By taking early measures to combat the spread, the country had a medical laboratory test for COVID-19 available as early as Jan. 24, and was able to focus medical laboratory testing on the most at-risk individuals
With the Coronavirus disease 2019 (COVID-19) outbreak dominating headlines and medical laboratories under growing pressure to increase testing capacity, Taiwan’s rapid response to the pandemic could provide a critical model for other countries to follow.
Given its proximity to mainland China—just 81 miles—and the large number of individuals who frequently travel back and forth between the countries, Taiwan was at risk of having the second-highest number of imported COVID-19 cases, according to a model developed by researchers at Johns Hopkins University and the University of New South Wales Sydney. News reports indicate that, each year, about 60,000 flights carry 10 million passengers between Taiwan and China.
Data from Taiwan’s Centers for Disease Control (CDC) and Central Epidemic Command Center (CECC) indicate that the country has managed to contain the outbreak thanks to these aggressive actions.
As of March 19, Taiwan’s CECC reported a total of 108 laboratory-confirmed COVID-19 infections. That compares with 81,155 in China, 41,035 in Italy, and 10,755 in the US, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. When the World Health Organization (WHO) reports on the number of COVID-19 cases by country, it includes the number of COVID-19 cases from Taiwan under the totals for the People’s Republic of China. WHO made this decision several years ago, under pressure by China to not recognize Taiwan as an independent nation.
The World
Population Review website says Taiwan’s population is about 23.8 million.
But its infection rate is low even on a per capita basis: Approximately 45
infections per million population, compared with 6,784 in Italy, 564 in China,
and 326 per million in the US.
The JAMA authors noted that Taiwan was prepared for
an outbreak after its experience with the severe
acute respiratory syndrome (SARS) pandemic in 2003, which also originated
in China.
Timeline of COVID-19 Outbreak at the Earliest Stages
Taiwan apparently learned a lesson about preparedness from
the SARS outbreak the rest of the world did not and that enabled the tiny
nation to respond immediately to the novel Coronavirus threat.
The country’s efforts began on Dec. 31 with inspections of
flight arrivals from Wuhan. “When there were only a very few cases [of
COVID-19] reported in China, [Taiwanese health authorities] already went onto
every airplane that came from Wuhan,” C. Jason Wang,
MD, PhD, an Associate Professor of Pediatrics and Director of the Center for Policy, Outcomes, and
Prevention at Stanford University and lead author of the JAMA
report, told Vox.
“Health officials came on the airplane and checked people for symptoms,” he
added.
Travelers who had recently visited Wuhan and displayed
symptoms of pneumonia were quarantined at home for 14 days. Taiwan’s
CDC reported that quarantined individuals were being tested for the
2019-nCoV coronavirus (later renamed to SARS-CoV-2)
soon after it was identified. The CECC, activated in January to coordinate the
government’s response, reported the first confirmed imported case on Jan. 21.
On Jan. 24, their
CDC announced that testing for the virus was being performed at the CDC and
eight designated hospitals. Testing included samples from physicians around the
country. As of Feb. 17, daily testing capacity was about 1,300 samples, the JAMA
authors reported.
Wang told Vox that aggressive measures to identify
and isolate at-risk individuals at the earliest stages reduced the volume of clinical
laboratory tests that had to be performed. “Here in the US and elsewhere, we’re
now seeing community spread,” he said. “It’s probably been here for a while.
And so now we’re trying to see, ‘Oh, how many people should we test?’ Then, you
really need to have a very large capacity in the beginning.”
“I think the US has enormous capacity that’s currently not being used,” C. Jason Wang, MD, PhD (above), Associate Professor of Pediatrics and Director of the Center for Policy, Outcomes, and Prevention at Stanford University and lead author of the JAMA report, told Vox. “We have big tech companies that really could do a lot, right? We ought to get the big companies together. Get the governors together, get the federal government agencies to work with each other, and try to find innovative ways to think about how to best do this. We’ve got the smartest people here in the US because they come from everywhere. But right now, those are untapped resources. They’re not working together. And the federal government, the agencies, they need to collaborate a little more closely.” (Photo copyright: Stanford University.)
More Actions by Authorities
The JAMA report supplementary materials notes a total of 124 actions taken by Taiwanese authorities between Jan. 20 and Feb. 24 to contain the outbreak. In addition to the border inspections, quarantines and testing, they included integration of data between the country’s National Health Insurance Administration and National Immigration Agency, so authorities, and later hospitals, could identify any patient who had recently traveled to China, Hong Kong, or Macau.
The steps also included:
An escalating series of travel restrictions,
eventually including suspension of most passenger flights from Taiwan to China,
as well as a suspension of tours to Hong Kong or Macau.
Use of government-issued cell phones to monitor
quarantined individuals.
Fines for individuals breaking the 14-day home
quarantine.
Fines for incoming travelers who failed to
provide accurate health information.
Fines for disseminating false information or
rumors about the epidemic.
Fines and jail sentences for profiteering on disease-prevention
products.
Designation of military camps and other
government facilities for quarantine.
Nationwide disinfection of universities,
colleges, and public spaces around schools.
The government also took aggressive action to ensure
adequate supplies of surgical masks, including stepped-up manufacturing, export
bans, price limits, and a limit of one to three masks per purchase.
The JAMA authors noted that government officials issued daily press briefings to educate the public about the outbreak. Communication efforts also included public service announcements by Taiwan Vice President Chen Chien-jen, a trained epidemiologist.
A poll taken in Taiwan on Feb. 17 and 18 indicated high approval ratings for officials’ response to the crisis.
The JAMA authors also noted some “challenges” in the
government’s response. For example, most real-time public communication was in
Mandarin Chinese and sign language, leaving out non-Taiwanese citizens in the
country. And the cruise ship Diamond Princess, later found to have infections
on board, was allowed to dock near Taipei and disembark passengers. There are
also questions about whether similar policies can be sustained through the end
of a pandemic.
Still, “well-trained and experienced teams of officials were
quick to recognize the crisis and activated emergency management structures to
address the emerging outbreak,” the JAMA authors wrote. “Taiwan is an
example of how a society can respond quickly to a crisis and protect the
interests of its citizens.”
One noteworthy difference in the speedy response to
recognition of a novel coronavirus in Taiwan, compared to recognition of the
same novel coronavirus in the United States, was the fast availability of
clinical laboratory tests for COVID-19 in Taiwan.
Pathologists and clinical laboratory professionals here in
the US are frustrated that their skills and talents at developing and
validating new assays on an accelerated timeline were not acknowledged and
leveraged by government officials as they decided how to respond to the
emergence of the novel coronavirus now called SARS-CoV-2.
In a separate study, HHS finds a 40% increase in sepsis cases, as more patients succumb to infections without effective antibiotics and antimicrobial drugs
Given the drastic steps being taken to slow the spread of the Coronavirus in America, it’s easy to forget that significant numbers of patients die each year due to antibiotic-resistant bacteria (ARB), other forms of antimicrobial resistance (AMR), and in thousands of cases the sepsis that follows the infections.
The CDC’s website states that “more than 2.8 million antibiotic-resistant infections occur in the US each year, and more than 35,000 people die as a result.” And a CDC news release states, “on average, someone in the United States gets an antibiotic-resistant infection every 11 seconds and every 15 minutes someone dies.”
Those are huge numbers.
Clinical laboratory leaders and microbiologists have learned to be vigilant as it relates to dangerously infectious antimicrobial-resistant agents that can result in severe patient harm and death. Therefore, new threats identified in the CDC’s Antibiotic Resistance Threats in the United States report will be of interest.
Drug-resistant Microbes That Pose Severe Risk
The CDC has added the fungus Candida auris (C. auris) and carbapenem-resistant Acinetobacter (a bacteria that can survive for a long time on surfaces) to its list of “urgent threats” to public health, CDC said in the news release. These drug-resistant microbes are among 18 bacteria and fungi posing a greater threat to patients’ health than CDC previously estimated, Live Science reported.
In 2013, the CDC estimated that about two million people each year acquired an antibiotic-resistant (AR) infection that killed as many as 23,000. However, in 2019, the CDC reported that those numbers were low and that the number of deaths due to AR infections in 2013 was about twice that amount. During a news conference following the CDC announcement, Michael Craig (above), a Senior Adviser for the CDC’s Antibiotic Resistance Coordination and Strategy Unit said, “We knew and said [in 2013] that our estimate was conservative … and we were right,” Live Science reported. In 2019, CDC reported 2.8 million antibiotic-resistant infections annually with more than 35,000 related deaths in the US alone. (Photo copyright: Centers for Disease Control and Prevention.)
The CDC considers five threats to be urgent. Including the
latest additions, they are:
Dark Daily has regularly covered the healthcare industry’s ongoing struggle with deadly fungus and bacteria that are responsible for hospital-acquired infections (HAI) and sepsis. This latest CDC report suggests healthcare providers continue to struggle with antimicrobial-resistant agents.
Acinetobacter Threat Increases and C. auris
a New Threat since 2013
Carbapenem-resistant Acinetobacter, a bacterium that
causes pneumonia and bloodstream and urinary tract infections, escalated from
serious to urgent in 2013. About 8,500 infections and 700 deaths were noted by the
CDC in 2017.
C. auris, however, was not addressed in the 2013
report at all. “It’s a pathogen that we didn’t even know about when we wrote
our last report in 2013, and since then it’s circumvented the globe,” said Michael
Craig, Senior Adviser for the CDC’s Antibiotic Resistance Coordination and
Strategy Unit, during a news conference following the CDC announcement, Live
Science reported.
Today, C. auris is better understood. The fungus
resists emerging drugs, can result in severe infections, and can be transmitted
between patients, CDC noted.
By year-end, CDC tracking showed 988 cases in the US.
More Patients Getting Sepsis as Antibiotics Fail: HHS
Study
In a separate study published in Critical Care Medicine, a journal of the Society of Critical Care Medicine (SCCM), the US Department of Health and Human Services (HHS) found that antibiotic-resistant bacteria and fungi are resulting in more people acquiring sepsis, a life-threatening condition, according to an HHS news release.
Sepsis increased by 40% among hospitalized Medicare patients
from 2012 through 2018, HHS reported.
“These (untreatable infections) are happening here and now in the United States in large numbers. This is isn’t some developing world thing. This isn’t a threat for 2050. It’s a threat for here and now,” Cornelius “Neil” Clancy, MD, Associate Chief of Veterans Affairs Pittsburg Health System (VAPHS) and Opportunistic Pathogens, told STAT.
It is troubling to see data about so many patient deaths
related to antibiotic-resistant infections and sepsis cases when the world is
transfixed by the Coronavirus. Nevertheless, it’s important that medical laboratory
leaders and microbiologists keep track of how the US healthcare system is or is
not responding to these new infectious agents. And, to contact infection
control and environmental services colleagues to enhance surveillance, ensure
safe healthcare environments and equipment, and adopt appropriate strategies to
prevent antibiotic-resistant infections.
Scientist described the speed at which SARS-CoV-2’s full sequence of genetic material was made public as ‘unprecedented’ and medical labs are rushing to validate tests for this new disease
In the United States, headlines scream about the lack of
testing for the novel Coronavirus
disease 2019 (COVID-19). News reporters ask daily why it is taking so long
for the US healthcare system to begin testing large numbers of patients for
SARS-CoV-2, the virus that causes COVID-19. Yet, pathologists
and clinical
laboratory scientists know that new technologies for gene sequencing
and diagnostic testing are helping public health laboratories bring up tests
for a previously unknown new disease faster than at any time in the past.
At the center of the effort to develop accurate new assays
to detect SARS-CoV-2 and help diagnose cases of the COVID-19 disease are medical laboratory
scientists working in public health
laboratories, in academic medical centers, and in research labs across the
United States. Their collective efforts are producing results on a faster
timeline than in any previous discovery of a new infectious disease.
For example, during the severe
acute respiratory syndrome (SARS) outbreak in 2003, five months passed
between the first recognized case of the disease in China and when a team of
Canadian scientists cracked the genetic code of the virus, which was needed to
definitively diagnose SARS patients, ABC
News reported.
In contrast, Chinese scientists sequenced this year’s
coronavirus (originally named 2019-nCoV) and made it available on Jan. 10,
2020, just weeks after public health officials in Wuhan, China, reported the
first case of pneumonia from the unknown virus to the World Health Organization
(WHO), STAT
reported.
Increases in sequencing speed enabled biotechnology
companies to quickly create synthetic copies of the virus needed for research. Roughly
two weeks later, scientists completed sequencing nearly two dozen more samples
from different patients diagnosed with COVID-19.
Molecular biologist Kristian Andersen, PhD (above right, with graduate students who helped sequence the Zika virus), an Associate Professor in the Department of Immunology and Microbiology at Scripps Research in California and Director of Infectious Disease Genomics at Scripps’ Translational Research Institute, worked on the team that sequenced the Ebola genome during the 2014 outbreak. He told STAT that the pace of sequencing of the SARS-CoV-2 coronavirus is “unprecedented.” (Photo copyright: Scripps Research.)
Lower Sequencing Costs Speed COVID-19 Diagnostics Research
Additionally, a significant decline in the cost of genetic synthesis is playing an equally important role in helping scientists slow the spread of COVID-19.In its coverage of the SARS-CoV-2 outbreak, The Verge noted that two decades ago “it cost $10 to create a synthetic copy of one single nucleotide, the building block of genetic material. Now, it’s under 10 cents.” Since the coronavirus gene is about 30,000 nucleotides long, that price reduction is significant.
Faster sequencing and cheaper access to synthetic copies is
contributing to the development of diagnostic tests for COVID-19, an important
step in slowing the disease.
“This continues to be an evolving situation and the ability to distribute this diagnostic test to qualified medical laboratories is a critical step forward in protecting the public health,” FDA Commissioner Stephen M. Hahn, MD, said in an FDA statement.
However, the Washington Post soon reported that the government-created coronavirus test kits contained a “faulty component,” which as of February 25 had limited testing in the US to only 426 people, not including passengers who returned to the US on evacuation flights. The Post noted that the nation’s public health laboratories took “the unusual step of appealing to the FDA for permission to develop and use their own [laboratory-developed] tests” for the coronavirus.
“This is an extraordinary request, but this is an extraordinary time,” Scott Becker,
Parallel efforts to develop and validate tests for COVID-19
are happening at the clinical laboratories of academic medical centers and in a
number of commercial laboratory companies. As these labs show their tests meet
FDA criteria, they become available for use by physicians and other healthcare
providers.
Dark Daily’s sister publication, The Dark Report just published an intelligence briefing about the urgent effort at the clinical laboratory of Northwell Health to develop both a manual COVID-19 assay and a test that can be run on the automated analyzers already in use in the labs at Northwell Health’s 23 hospitals. (See TDR, “Northwell Lab Team Validates COVID-19 Test on Fast Timeline,” March 9, 2020.)
Following the FDA’s March 13 EUA for the Thermo Fisher test,
Hahn said, “We have been engaging with test developers and encouraging them to
come to the FDA and work with us. Since the beginning of this outbreak, more
than 80 test developers have sought our assistance with development and
validation of tests they plan to bring through the Emergency Use Authorization
process. Additionally,” he continued, “more than 30 laboratories have notified
us they are testing or intend to begin testing soon under our new policy for
laboratory-developed tests for this emergency. The number of products in the
pipeline reflects the significant role diagnostics play in this outbreak and
the large number of organizations we are working with to bring tests to
market.”
Pharma Company Uses Sequencing Data to Develop Vaccine in
Record Time
Even as clinical laboratories work to develop and validate diagnostic tests for COVID-19, drug manufacturers are moving rapidly to develop a COVID-19 vaccine. In February, Massachusetts-based biotechnology company Moderna Therapeutics (NASDAQ:MRNA) announced it had shipped the first vials of its potential coronavirus vaccine (mRNA-1273) to the National Institute of Allergy and Infectious Disease (NIAID) for use in a Phase One clinical trial.
“The collaboration across Moderna, with NIAID, and with CEPI [Coalition for Epidemic Preparedness Innovations] has allowed us to deliver a clinical batch in 42 days from sequence identification,” Juan Andres, Chief Technical Operations and Quality Officer at Moderna, stated in a news release.
The Wall Street Journal (WSJ) reported that NIAID expects to start a clinical trial of about 20 to 25 healthy volunteers by the end of April, with results available as early as July or August.
“Going into a Phase One trial within three months of getting the sequence is unquestionably the world indoor record,” NIAID Director Anthony Fauci, MD, told the WSJ. “Nothing has ever gone that fast.”
There are no guarantees that Moderna’s coronavirus vaccine
will work. Furthermore, it will require further studies and regulatory
clearances that could delay widespread distribution until next year.
Nonetheless, Fauci told the WSJ, “The only way you
can completely suppress an emerging infectious disease is with a vaccine. If
you want to really get it quickly, you’re using technologies that are not as
time-honored as the standard, what I call antiquated, way of doing it.”
In many ways, the news media has overlooked all the important
differences in how fast useful diagnostic and therapeutic solutions for
COVID-19 are moving from research settings into clinical use, when compared to
early episodes of the emergence of a new infectious disease, such as SARS in
2003.
The story the American public has yet to learn is how new
genetic sequencing technologies, improved diagnostic methods, and enhanced
informatics capabilities are being used by researchers, pathologists, and
clinical laboratory professionals to understand this new disease and give
healthcare professionals the tools they need to diagnose, treat, and monitor
patients with COVID-19.
At present, medical laboratories are collecting blood specimens for testing by authorized public health labs. However, clinical laboratories should prepare for the likelihood they will be called on to perform the testing using the CDC test or other tests under development.
“We need to be vigilant and understand everything related to the testing and the virus,” said Bodhraj Acharya, PhD, Manager of Chemistry and Referral Testing at the Laboratory Alliance of Central New York, in an exclusive interview with Dark Daily. “If the situation comes that you have to do the testing, you have to be ready for it.”
The current criteria for determining PUIs include clinical features, such as fever or signs of lower respiratory illness, combined with epidemiological risks, such as recent travel to China or close contact with a laboratory-confirmed COVID-19 patient. The CDC notes that “criteria are subject to change as additional information becomes available” and advises healthcare providers to consult with state or local health departments if they believe a patient meets the criteria.
Bodhraj Acharya, PhD (above), is Manager of Chemistry and Referral Testing at the Laboratory Alliance of Central New York. In an exclusive interview with Dark Daily, he stressed the importance that medical laboratories be prepared. “We need to be vigilant and be active and understand everything related to this virus and the testing. That’s the role of clinical laboratory scientists, to be ready because this can become a pandemic anytime. It can spread and tomorrow the CDC could announce it is disseminating the test to designated laboratories.” (Photo copyright: Laboratory Alliance of Central New York.)
Test Kit Problems Delay Diagnoses
On Feb. 4, the FDA issued a Novel Coronavirus Emergency Use Authorization (EUA) allowing state and city public health laboratories, as well as Department of Defense (DoD) labs, to perform presumptive qualitative testing using the Real-Time Reverse Transcriptase PCR (RT-PCR) diagnostic panel developed by the CDC. Two days later, the CDC began distributing the test kits, a CDC statement announced. Each kit could test 700 to 800 patients, the CDC said, and could provide results from respiratory specimens in four hours.
However, on Feb. 12, the agency revealed in a telebriefing that manufacturing problems with one of the reagents had caused state laboratories to get “inconclusive laboratory results” when performing the test.
“When the state receives these test kits, their procedure is to do quality control themselves in their own laboratories,” said Nancy Messonnier, MD, Director of the CDC National Center for Immunization and Respiratory Diseases (NCIRD), during the telebriefing. “Again, that is part of the normal procedures, but in doing it, some of the states identified some inconclusive laboratory results. We are working closely with them to correct the issues and as we’ve said all along, speed is important, but equally or more important in this situation is making sure that the laboratory results are correct.”
During a follow-up telebriefing on Feb. 14, Messonnier said
that the CDC “is reformulating those reagents, and we are moving quickly to get
those back out to our labs at the state and local public health labs.”
Above is a picture of CDC’s laboratory test kit for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). CDC is shipping the test kits to laboratories CDC has designated as qualified, including US state and local public health laboratories, Department of Defense (DOD) laboratories, and select international laboratories. The test kits are bolstering global laboratory capacity for detecting SARS-CoV-2. (Photo and caption copyright: Centers for Disease Control and Prevention.)
Serologic Test Under Development
The current test has to be performed after a patient shows
symptoms. The “outer bound” of the virus’ incubation period is 14 days, meaning
“we expect someone who is infected to have symptoms some time during those 14
days,” Messonnier said. Testing too early could “produce a negative result,”
she continued, because “the virus hasn’t established itself sufficiently in the
system to be detected.”
Messonnier added that the agency plans to develop a serologic test that will identify people who were exposed to the virus and developed an immune response without getting sick. This will help determine how widespread it is and whether people are “seroconverting,” she said. To formulate this test, “we need to wait to draw specimens from US patients over a period of time. Once they have all of the appropriate specimens collected, I understand that it’s a matter of several weeks” before the serologic test will be ready, she concluded.
“Based on what we know now, we believe this virus spreads
mainly from person to person among close contacts, which is defined [as] about
six feet,” Messonnier said at the follow-up telebriefing. Transmission is
primarily “through respiratory droplets produced when an infected person coughs
or sneezes. People are thought to be the most contagious when they’re most
symptomatic. That’s when they’re the sickest.” However, “some spread may happen
before people show symptoms,” she said.
The virus can also spread when people touch contaminated surfaces and then touch their eyes, nose, or mouth. But it “does not last long on surfaces,” she said.
Where the Infection Began
SARS-CoV-2 was first identified during an outbreak in Wuhan, China, in December 2019. Soon thereafter, hospitals in the region “were overwhelmed” with cases of pneumonia, Dr. Acharya explained, but authorities could not trace the disease to a known pathogen. “Every time a new pathogen originates, or a current pathogen mutates into a new form, there are no molecular tests available to diagnose it,” he said.
So, genetic laboratories used next-generation sequencing, specifically unbiased nontargeted metagenomic RNA sequencing (UMERS), followed by phylogenetic analysis of nucleic acids derived from the hosts. “This approach does not require a prior knowledge of the expected pathogen,” Dr. Acharya explained. Instead, by understanding the virus’ genetic makeup, pathology laboratories could see how closely it was related to other known pathogens. They were able to identify it as a Betacoronavirus (Beta-CoVs), the family that also includes the viruses that cause SARS and Middle East Respiratory Syndrome (MERS).
This is a fast-moving story and medical laboratory leaders are advised to monitor the CDC website for continuing updates, as well as a website set up by WHO to provide technical guidance for labs.
The self-cleaning material has been proven to repel even the deadliest forms of antibiotic resistant (ABR) superbugs and viruses. This ultimate non-stick coating is a chemically treated form of transparent plastic wrap which can be adhered to surfaces prone to gathering germs, such as door handles, railings, and intravenous therapy (IV) stands.
“We developed the wrap to address the major threat that is posed by multi-drug resistant bacteria,” Leyla Soleymani, PhD, Associate Professor at McMaster University and one of the leaders of the study, told CNN. “Given the limited treatment options for these bugs, it is key to reduce their spread from one person to another.”
According to research published in the peer-reviewed Southern Medical Journal, “KPC-producing bacteria are a group of emerging highly drug-resistant Gram-negative bacilli causing infections associated with significant morbidity and mortality.”
Were those surfaces covered in this new bacterial-resistant
coating, life-threatening infections in hospital ICUs could be prevented.
Taking Inspiration from Nature
In designing their new anti-microbial wrap, McMaster researchers took their inspiration from natural lotus leaves, which are effectively water-resistant and self-cleaning thanks to microscopic wrinkles that repel external molecules. Substances that come in contact with surfaces covered in the new non-stick coating—such as a water, blood, or germs—simply bounce off. They do not adhere to the material.
The “shrink-wrap” is flexible, durable, and inexpensive to
manufacture. And, the researchers hope to locate a commercial partner to
develop useful applications for their discovery.
“We’re structurally tuning that plastic,” Soleymani told SciTechDaily. “This material gives us something that can be applied to all kinds of things.”
In the video above, Leyla Soleymani, PhD, Associate Professor at McMaster University, explains how “The new plastic surface—a treated form of conventional transparent wrap—can be shrink-wrapped onto door handles, railings, IV stands, and other surfaces that can be magnets for bacteria such as MRSA and C. difficile. This may be technology that has great value to clinical laboratories and microbiology laboratories. Click here to watch the video. (Image and video copyright: McMaster University/YouTube.)
Industries Outside of Healthcare Also Would Benefit
According to the US Centers for Disease Control and Prevention (CDC), at least 2.8 million people get an antibiotic-resistant infection in the US each year. More than 35,000 people die from these infections, making it one of the biggest health challenges of our time and a threat that needs to be eradicated. This innovative plastic coating could help alleviate these types of infections.
And it’s not just for healthcare. The researchers said the coating could be beneficial to the food industry as well. The plastic surface could help curtail the accidental transfer of bacteria, such as E. coli, Salmonella, and Listeria in food preparation and packaging, according to the published study.
“We can see this technology being used in all kinds of institutional and domestic settings,” Tohid Didar, PhD, Assistant Professor at McMaster University and co-author of the study, told SciTechDaily. “As the world confronts the crisis of anti-microbial resistance, we hope it will become an important part of the anti-bacterial toolbox.”
Clinical laboratories also are tasked with preventing the
transference of dangerous bacteria to patients and lab personnel. Constant
diligence in application of cleaning protocols is key. If this new anti-bacterial
shrink wrap becomes widely available, medical laboratory managers and
microbiologists will have a new tool to fight bacterial contamination.
