As pathologists, patient advocacy and safety have quite unique meanings as compared to our colleagues on the wards and in the clinics. It is such a unique opportunity to affect further care and treatments, depending on how testing is used. I find the combination of patient advocacy within the clinics an opportunity for pathologists to possibly meet patients and learn from our clinical colleagues about how much the lab truly affects patient care.
At my institution, we have what is designated as “Diagnostic Management Teams” (DMT). At each DMT, our clinical pathology teams perform actions such as writing interpretations for difficult test panels or review the charts to make sure teams have changed their patients to the proper antibiotics. . In our coagulation DMT, we write the interpretations for complex esoteric coagulation studies to ensure: 1. the right tests were ordered, and if they weren’t, we recommend which are appropriate, 2. these complex tests are explained in a way that is understandable to our clinical colleagues and 3. proper patient care and safety for tests which are very critical to patients. To add a layer to this complex testing system, we also have the opportunity to attend benign hematology clinic with one of our attendings. I found this experience to be rather eye opening. Pediatrics hematology clinic is an interesting place whose patients are diagnosed with a wide variety of diseases. A vast majority of these pediatric patients have a parent who has been deemed a “bleeder” or a “clotter” at some point in their lives, or the patients themselves have exhibited such conditions. Often, the parents do not have a definitive diagnosis, and so the investigation begins. The hematologist, who also is one of the coagulation DMT attendings, will order panels which fit with clinical history not only on the patient but more often than not on their parents as well. This allows the DMT to analyze the nuances of the complex coagulation system, even down to multimer gels to figure out which type of von Willebrand disease a patient may have. Although these clinic visits may seem superficial, they give families such a comfort to know a classification of their disease, how it can be treated and if it has been passed down to the actual patient, their child. One such instance, we actually produced a family pedigree with the type of von Willebrand disease within them and then did confirmation testing. Seeing the delivery of information and subsequent relief on the patients’ faces is always a gentle reminder of how much we affect and advocate for our patients in the lab, which starts with the order or a “simple test.”

When I was approached about writing an essay about our rural lab, I was initially stymied. There’s a universality about the work we do; tech work is pretty much the same wherever you go. A differential is a differential in the biggest cities and smallest towns. The thing that makes us unique is that we’re 50 miles from a city with a full-service hospital and many of our patients are elderly and don’t drive, so we try to cobble together as much care as we can give them in a clinic setting.
Our clinical laboratory is a small independent lab in Cairo, IL, midway between Memphis and St. Louis. We are attached to a regional system of rural clinics that provides care for the residents of the poorest counties in Illinois. We are the only high-complexity FQHC lab in the country, and we’re extremely proud of the work we do with our limited financial and geographical resources.
Our part in battling the COVID-19 pandemic feels a little odd compared to the work of hospital labs. We see our job as keeping our patients out of the overburdened hospitals for as long as possible. We screen everyone who presents with a fever for flu and strep. That includes the prisoners from the two local prisons, the nursing home patients in all the small towns scattered around rural southern Illinois, the teachers, daycare and home health workers. The criteria for a C-19 test is still very stringent in Illinois and most of our patients don’t yet meet it. We generally send them home with free samples of over-the-counter palliative meds, instructions about avoiding other people, and what new symptoms they should watch for.
Even so, we’re running low on basic supplies: PPE, swabs, disinfectant, etc. Like everyone else, we’re having trouble finding more. Yesterday I took a couple of hours to open every cabinet and paw through every box, hunting for overlooked supplies. There was a stash of sixty N95 masks in a closet and forty painter’s masks left over from when the lab was built. The box claims the masks “have N95 properties”…whatever that means. Hopefully we won’t have to find out. I distributed the N95 masks to the clinics that were running low and traded a box of disposable lab coats to our local clinic for 3 hazmat suits for our lab staff. I sent a few dozen more nasopharyngeal swabs to the prison with instructions to use them sparingly. We’re currently backordered until mid-April for more.
All the techs I know (locally and all around the country) are pretty fatalistic about this. We expect to be infected. We’re hoping it’ll be later rather than sooner and we’re trying to protect our more medically fragile and/or elderly colleagues. As you probably know, the average age of MTs in this country is about my age…56. A new virus brings attention to the medical lab profession, and that causes a brief uptick in new interest in our field, but we’re chronically understaffed and techs are retiring faster than we can train new ones to replace them.
In the meantime, of course, we continue to test and treat our regular patients. Mostly poor, mostly elderly, for the diabetes, hypertension, cardiovascular diseases and cancers that are the meat and potatoes of rural health. The concession they’ve made to social distancing is that less of them hug me, although a fair number say “If it’s my time, it’s my time” and hug me anyway. Many of our patients don’t drive, and they arrive one by one on the transit vans designed to seat 12 that pick them up from home. I wonder if the van driver disinfects between patients. I wonder if the patients know he ought to. I assume they hug him, too, so it probably doesn’t matter. This coronavirus crisis will eventually wind down, but the ongoing needs of medically underserved rural communities will continue unabated. Our hope is that this pandemic shines a big light on the many challenges of providing quality care to geographically large, sparsely populated rural communities.

I’ll get straight to the point this time: there’s a legitimate crisis happening in our world that is highlighting a multitude of things. Just to name a of few: the complex intersection of state-sponsored healthcare as a human right, the availability of resources to clinical personnel, the logistics and implications of public health measures to the average person, our global connectivity, and lack of damn tests!
And that’s our stop. Please take a minute to locate your exits, as they may be behind you, and get ready to talk about this SUPER CRITICAL aspect of the COVID-19 pandemic. What are clinical tests?
I know, this “viral” topic right now will be shared and spread to a vast array of audiences. So, I’m going to try something new here. The last four years of posts on this blog have been aimed somewhere between laboratory professionals and working clinicians. I open a rare window into our clinical world from time to time, but this pandemic is something affecting everyone. Today, we’ve got a major problem about what’s being said in the media and who understands which parts of it…so, as I discuss some major points below, I will take short pauses to highlight clinically relevant information as well as put things in plain, simple terms for all of us to get up to speed together.
(If you are one of my clinical colleagues, from the bench to the bedside, your notes will be in BLUE. If you are not in the healthcare world, or just want some simple clarification, your notes are going to be GREEN. Let’s run an example so you can see what I mean…)
Last month I talked about the background and biology of the SARS-CoV-2 virus as a novel, emerging pathogen and potential pandemic and discussed how we must contextualize these epidemics with proper understanding of data and statistics. Numbers are important and if we’re going to combat a super bug, we’ve got to know what it is, how it acts, where it came from, and what’s happening in the field. A subsequent and fantastic post right after mine by Dr. SoRelle at UTSW, discussed how to validate a COVID-19 test in your laboratory. Basically, he presented a snapshot of the current climate of academic hospital labs now depending on LDTs to respond to the pandemic and discussed where to read more, what limitations testing might have, and how to address things like designing/purchasing primers, cross-reactivity, detection capabilities, and EUAs under the new FDA guidance.
But back to business, this month we’re talking about testing, and if you just google search “COVID-19” in the states, you’re met with a myriad of failure stories…
“As US fumbles COVID-19 testing, WHO warns social distancing not enough” (source)
“Limited access to COVID-19 tests frustrates patients, health professionals” (source)
“What went wrong with coronavirus testing in the US” (source)
“Why coronavirus testing in the US is so delayed” (source)
“America’s shamefully slow coronavirus testing threatens all of us” (source)
I’ll stop torturing you. You’re forced to watch and/or read enough news as it is nowadays (you’re social distancing, right? …right?) I mean, even Norway took a jab and called us “underdeveloped” citing our poorly developed healthcare delivery system—ouch. So, what’s the big problem with testing? What stark revelation exists between all these different news sources and highlights our “laboratory failures” in America? Well, luckily nearly all of these lab-fail stories aren’t aimed at our labs at all, they’re aimed at governmental decisions and red tape traps. But that’s hard to get to in a sea of clickbait. So instead of giving you more rabbit-hole lab talk, let’s talk about two main tenets of this narrative that everyone should be aware of: what laws affect lab tests and what does it mean to create a new lab test? After we clear the air for those two key points, we’ll come back around and tell you what COVID-19 looks like in the medical laboratory.
The Law of the Lab
There are SO MANY regulations and accrediting bodies that govern the way labs operate, deliver results, and function in clinical settings. Let’s name some! Various federal, state, and local laws ensure the highest calibers of safety and accountability for clinical and research laboratories; laws from OHSA, the FDA, recommendations from the CDC and local health departments; regulations for mechanical, noise, chemical, exposure, pathogen/infectious safety, pollution, radiation, blah blah blah! Trust me, there are a ton. What feels ever present to us laboratorians are the accrediting and inspection agencies that grant us authority to continue performing our clinically vital roles. Joint Commission, FDA, and other inspections make sure hospitals are up to snuff. Laws that govern what labs can do what tests fall under CLIA. They help us define high complexity to waived (not complex) testing. There’s a massive difference in a clinical office’s medical assistant obtaining a point of care (POCT) glycated hemoglobin (Hgb A1c) than a medical laboratory scientist conducting a hemoglobin electrophoresis study, and that difference highlights specialized training, laboratory ability, safety and quality requirements.
Accreditations and recommendations can come from many professional societies like the CAP, ASCP, AABB, AACC, ASM, ASH, and many subspecialized groups. Laboratorian trigger warning: I’m a certified CAP inspector. No; you don’t have to put away your desktop coffee…for now. But I’ve certainly—along with all of you—been wholly immersed in the endless accreditation and regulation protocols we follow. We know exactly why these regulations exist and we should talk more about them, since they define our role as such a critical one.
Feeling Validated Yet?
Some of you lost a breath when I said CAP inspector. The rest of you may now spit out your coffee and run for the hills because I’m talking about VALIDATIONS. Rotating MLS students sometimes do their capstones or theses on validating a test or instrument, but we do them because that’s just a part of our job! So what goes into validating a test? The short answer: a whole lot. The long answer: a whole lot more! Let’s take PCR testing for example, it’s topical because we’re talking about COVID-19 testing and that’s the prime modality so let’s explore that validation.
So, you want to add a qPCR to your lab’s test menu, eh? You first have to decide quantitative or qualitative. If its quantitative you’re in for a treat—yay statistical variant analysis! You have to prove applicability, practical application, specificity, sensitivity, efficiency, correlatable translation into useful clinical data. Detecting a number or degree of mutations? Make sure its accurate and precise (and repeatable). Buying commercial kits or making your own in-house assay? What about a qualitative test, just a simple yes or no. Easier right? Not really, you need to prove most of the same data and statistical soundness depending on methodology used, instrumentation, nature of variation, etc. AND: it all must be documented, proven, up to regulatory standards, and you better have a database FULL of data that proves your test works. Now, I have good news and bad news.
The good news: this is pretty routine, and pretty easy to follow even for simple new tests your incorporating from commercial vendors with ready-to-validate test kits. The bad news: COVID-19 is not this type of test. Say what you will about the US’s decision to NOT utilize the WHO testing model available weeks ago, the CDC responded in kind here by providing a two-control kit that SLOWLY started to break out. Using this as a model, many labs in academic hospital pulled the trigger on their LDT work. (LDT = laboratory developed tests) I’ve already revealed myself as a CAP inspector (pshh, not even my final form!) and I can tell you that there are hundreds of citations for how to validate already existing tests, compare tests across different instruments, compare them across the same instrument, prove your statistical ability to ensure quality results, and even how to make your own test from scratch! Talk about extra work!
Running COVID-19 testing alongside B. burgdorferi: Corona…with Lyme?
Now we’ve come to the heart of the current discussion. Dr. SoRelle talked about validating a COVID-19 assay last month, so I’m letting him take point on that—read his piece, its great! What we’re talking about today is what exactly regulations and validations have to do with COVID-19 testing. Remember the regulations that say how laboratories run tests and operate clinically? Okay, well there are issues with this narrative. You’ll see plenty of news stories about the regulatory red tape that has hindered lab professionals from providing COVID testing. This makes it sound like because of “rules” we just can’t give them out to everyone, or we can’t set up testing for whatever regulatory reason. This is not the case. This is how the relationship between those aforementioned regulatory bodies work. The FDA makes sure labs operate up to federal standards and, and specifically, enforce regulations outlined in CLIA. While the FDA would like to call tests/results products of analyzers/devices to fall in their prevue, the interpretation and translation of that clinical data is not a print out but a MEDICAL SPECIALTY—hi, I’m pathologist #2465827, part of the FDA regional lab result response team—nope. Lab developed tests (LDTs) are not FDA products, but CLIA certified processes that only CLIA certified laboratories can perform. No CLIA no LDT—it’s as simple as that. You now understand that a lot goes into a single test, and that not every lab can perform high-complexity testing, thus, not every lab is CLIA certified to do LDTs… which means no COVID testing for them.
Okay, the other half of the narrative says that because of a lack of supplies from industry vendors, commercial kits were unavailable either from them or the CDC and if they got them, their reagents were not good. Frustrated, scorned immunology/chemistry lab specialists decide, “we’ll show them…we’ll make our own test! *evil laugh*” A bit dramatic, because it is dramatic. That’s not how LDTs work. How, then, do we get to LDTs? That answer is simple: regardless of politics, resources, or any other social concerns, medical laboratorians and clinical pathologists are part of the essential healthcare team that strives to care for the sick and hopes to prevent unnecessary infection or illness. We’re in this together and if one system can’t provide tests for the whole country, hundreds of thousands of hospitals will rise to the occasion and share partial LDTs or create their own. Just like with any other test, labs know full well how to get this done and work together to do it.
But what about the stories that say some tests take 8 hours vs others that take 4 days to turn around results? How come some kits came with 2 swabs, and some with 3? Why did other countries like South Korea do a lot better than us in testing their population? Did we wait too long to set up LDTs? Can’t I just go to my doctor and get tested now? Okay, okay, I hear you. This is where it gets heavy, especially in the media. The takeaway can be a simple comparison: look back to the Zika epidemic. Zika is an Arbovirus/Flavivirus that we knew about for roughly 60 years. As such, we had time to understand it and create tests quickly that measured exposed patients’ antibody response to acute or resolved infections. Even simpler, Zika is part of a family of mosquito-borne illnesses that we generally understand pretty well. SARS-CoV-2 is not like Zika. The word “novel” is used because it’s just that: brand spankin’ new. And, even though it’s a cousin of its predecessor in the old SARS epidemic, we’ve been racing the clock to create accurate and reliable testing. That’s why there’s so much variability happening across commercial industry to academic hospital laboratories.
I love to make puns but let me be clear: this is a serious global pandemic, as defined by the CDC and WHO and we must understand this fully and appropriately. We’re still in the dark about a lot of data, mostly because of missing numbers. What we do know continues to inform our daily-changing climate of public health awareness in the US. The following images speak for themselves and I’ve collected them as a resource and snapshot for you to look through, just to get your SARS-CoV-2 bearings.
What can I say? It’s hard to write a conclusion about something that’s changing every day. I’ve been doing my best editing to keep this as up to date as it could possibly be for publication, but there are a million more resources sitting in the queue that I wish I could walk you all through. But I think, at the end of the day, what we need to remember is one simple thing: we’ve been here before and we’ll be here again. Public health epidemics and our responsiveness is one of the more serious aspects of laboratory medicine and pathology, not to mention healthcare at large. I said it last month that we’re lucky that this isn’t an influenza-type virus, because that would look a lot different. There are still some highly serious infectious etiologies out there more lethal than COVID-19, but this pandemic is bringing to light a lot of public health awareness and an opportunity to examine our population’s medical/health literacy, our policy priorities, our strength and resolve, as well as our ability to adapt.
In the coming days, weeks, months you’re going to most likely hear about municipal infrastructures cutting back on things in order to prevent the spread of the virus. Listen to these warnings and heed the advice of the medical community. If you think you’re being a hero by braving the storm, you’re no better than a mosquito that carries malaria with no symptoms itself. Wash your hands, practice appropriate social distancing, continue your daily life with your necessary trips out being mindful of what those of us in healthcare live with on a daily basis. Practice compassion as well, just because we’re social distancing to “flatten the curve” doesn’t mean its time for martial law and cleaning supply hoarding. I know these are serious times, but humor and compassion can be infectious too.
Thank you for reading.

While washing my hands in an airport restroom, “Until the End of the World” by U2 (Achtung Baby, 1991, Island Records) was playing over the toilet speakers. As I watched several people incorrectly wash their hands during this current pandemic, the songs lyrics (which I have known by heart since 1991) rang through my brain and struck a new chord with me. There are plenty of doomsday songs that actually make us happy (Prince’s 1999, from 1999, 1982, Warner Bros.; R.E.M.’s “It’s the End of the World as We Know It,” from Document, 1987, I.R.S. Records) despite the dark images in the lyrics. And then here are a whole host of doomsday songs that are dark and brooding (“Man Comes Around” by Johnny Cash, “Waiting for the End of the World” by Elvis Costello, “It’s Not the End of the World but I Can See it from Here” by Lostprophets, and “Preaching the End of the World” by Chris Cornell, etc.). It turns out you can write a doomsday song after a breakup with your partner (“The End of the World” by Skeeter Davis) or in response to nuclear war fears (“Everyday is Like Sunday”by Morrissey).
What struck me in my new feeling of U2’s track was the dichotomy of viewpoint by the two principal voices in the song. The speaking voice is in it for the short game, in it for “me.” The listener in the song is in it for the long game, in it for “we.” Considering both the inspiration for the song personally for Bono as well as the historical character about which the song is based, this might be kind of obvious to most of us. However, in 2020, as we face what can only be described as a venomous divergence of voices, the lyrics force me to think about individuals’ motivations, agendas, messages, points of view, and goals when they speak, text, post, or otherwise communicate their opinions and that such opinions come in two flavors. There are those that are in this for themselves. There is no other valid observation than selfishness, conceit, arrogance, and disrespect for others. There are those that are in this for everyone. There is no other valid observation than collaboration, caring, selflessness, humility, and respect.
Considering that, regardless of your moral compass or who your parents were, most children are theoretically raised to be like the latter but the innate, instinctive traits of our evolution are really the former. Thus, as many great philosophers and thinkers have concluded, the intellectual evolution of the human mind and personality is such that seeing and caring for “the other”, even more than for ourselves, is a mark of high achievement while base, crude attacks on “the other” are marks of devolved, unintelligent individuals. Notice that there is no good and evil in this argument. There is only awareness of self and awareness of others and choosing one over the other. Naturally, the best life is to balance our care for ourselves and our care for others, which, some would argue, is one of the most valuable aspects of organized religion. As I am a non-religious person—despite the fact that the U2 track is one of my favorites—I strive to achieve that balance through a universal moral compass perspective which includes a great deal of importance on the safety, security, health, well-being, and happiness of others.
COVID-19 and its viral cause, SARS-CoV-2, have sent incredible ripples, waves, and tsunamis across every aspect of human life in the last 6 months. Pandemic preparedness and responsiveness is a “we” activity. China very much had a “we” approach to health (among many other sectors) which was evident by their incredible response to SARS originally in 2002. Some would argue that had SARS emerged in any other country, it would have gone pandemic at a much faster rate with horrible consequences; yet, emergence in China meant the virus was facing a huge pre-programmed response. But importantly in the 2002 outbreak, CDC officials from the US were relocated to China and work closely with the Chinese government to plan, implement, and execute daily changes to the management of the outbreak. Relationships being what they are, China did not interact as closely with the US for COVID-19 and, thus, the response was not as successful. In healthcare, as in many areas of human life, we are stronger together, and we will be more successful with transparency and communication than with secrecy and seclusion. The health of humanity should not be a geopolitical issue.
The diagnostic medical team (DMT), composed of pathologists and laboratory professionals, is the backbone of modern healthcare. However, these are also people who have underlying conditions, have elderly parents, have to ride the train to work, etc. Everyday, even when there isn’t a pandemic, members of the DMT place their own personal health and safety on the line to provide patients with rapid, accurate diagnoses and continuous care. Fortunately, laboratorians are well versed in protecting themselves within the laboratory from potential risks; however, in a pandemic situation, they must also protect themselves from external risks, else the laboratory staffing falls below the levels that insure high quality patient care is available.
COVID19 testing by RT-PCR of SARS-Cov-2, for example, is a high complexity laboratory test that is often performed by a select number of laboratorians and not by all laboratory staff. When we hear discussions of laboratory testing for COVID and money for such testing or availability of kits, it must also be noted that the laboratory is the only segment in the system who can take money and tests and turn it into data that saves lives—but only if they have sufficient people to make this happen. Healthcare facility leadership and national leadership must support those teams by providing all necessary resources to meet the needs of patients including the laboratory direct and indirect needs. Expanding the ability of personnel in the laboratory to meet this emergent need through cross-training and potential emergency staffing coverages is essential to successfully navigating this pandemic.
The DMT is always practicing the “we.” But now that the pandemic requires transparency and communication for success, the entire health system must amplify the practice of “we” and advocate with external leaders for every member of the healthcare team, but especially the laboratories. It is no time for “me” in this situation. Hand washing, social distancing, and self-quarantine may seem like things that protect “me” but it is clear that the goal is rooted in protecting “we.” Flattening the curve may prevent the healthcare systems from becoming overburden; however, laboratories are going to be massively overburdened regardless. Asymptomatic, symptomatic with other diseases, and true cases of COVID19 all have to be tested and there isn’t a precedent for the pace the disease is moving. Laboratories are coming online this week (March 16th) with testing that needed to be available in January. Laboratory staff must be enabled and mobilized to meet this current needs. We are all behind the curve on this one, but I have full confidence in our DMTs to get this done if they can be supported. There will be struggle but the tenacity and perseverance of our nation’s laboratory professionals and pathologists will see this through to its end. Because we, the DMT, don’t have a choice but to always consider the “we” in our daily practice, our patients WILL BE tested and diagnosed. We will beat this together and in being together, we will be stronger.

In the 1986 remake of the horror film “The Fly,” the character played by actress Geena Davis has a great line. When she warns another person about the extremely unsafe behaviors of the title character, she says, “Be afraid…be very afraid!” Clearly this woman in the story understands the dangers involved in hanging out with a man whose mind is slowly being dominated by a killer creature. As a lab safety professional, one of my greatest wishes is that laboratorians would understand the danger they can be in when they permit unsafe behaviors in those around them.
Coaching fellow lab workers about safer behaviors is perhaps one of the most powerful and important tools we have to improve the overall safety culture, but it is also one of the most difficult tools to use. There are a variety of reasons we don’t do well with speaking up when we notice unsafe activities. Some laboratorians are introverts, and saying something that could be perceived as forward or direct just isn’t natural for them. There are those who do not want to correct co-workers or friends since doing so might somehow damage the relationship. Others don’t say anything because doing so in the past had no noticeable results.
The damage done by not coaching others for safety is terrible, and unfortunately, it’s easy to do. Repairing this damage, on the other hand, can be a slow and difficult process. Albert Einstein said, “The world is not a dangerous place because of those who do harm, but because of those who look on and do nothing.” That means that when we see unsafe behaviors, we have a responsibility to do take action against them. Otherwise when we do nothing, we are essentially giving permission for those dangerous behaviors to go on. That will only lead to a worsening lab safety culture, and eventually there will be increasing amounts of injuries and exposures.
With the rapid spread of COVID-19 in the Unites States, the number of questions that have arisen about lab safety has climbed exponentially. I am excited about any uptick in interest in laboratory safety issues, but I wish it didn’t take a world-wide pandemic to cause it. The Centers for Disease Control (CDC) has offered very good lab safety instruction for the processing and testing of COVID-19 specimens (https://www.cdc.gov/coronavirus/2019-ncov/lab/index.html), and virus testing is being performed in more labs each day.
It is vital for laboratorians to remember this. While the coronavirus is not to be taken lightly, the patient specimens we handle every day contain biohazards that are far more dangerous to us than COVID-19. Hepatitis, HIV, select agents, and many other pathogens reside in the blood and body fluids processed and tested in laboratories across the country, and many of the illnesses these agents can cause are very hazardous to human health. I hope we remember that when the hype about this latest virus passes.
Use Standard Precautions when working in the laboratory. Wear lab coats, gloves, and face shields. When you see a co-worker who is not properly attired, offer them the PPE they need. If you see an unsafe practice like eating, drinking, or using cell phones in the department, end it quickly. That is how infections occur, and that is how they spread into the community. Remember, unsafe behaviors can have a direct affect on the safety of the entire team. The sooner we can help everyone to understand that, the better we will all be at coaching others. In the original 1958 version of “The Fly,” the title character is caught in a spider’s web. His famous (and often imitated) last words were, “Help me! Help meeeee!” The scientist practiced unsafe behaviors until it was too late to turn back. Don’t let that be the case for anyone in your laboratory!

According to this recently-published study in the Journal of Histotechnology, ” … experts are confident that 70% ethanol and 0.1% sodium hypochlorite should inactivate the virus. Formalin fixation and heating samples to 56oC, as used in routine tissue processing, were found to inactivate several coronaviruses and it is believed that 2019-nCoV would be similarly affected.”
