South Asian nation aims to do what US, UK, and Europe failed to do during start of COVID-19 pandemic and slow spread of disease while case counts are low
With monkeypox quickly spreading around the world, India may be taking a lesson from western nations’ delayed response to COVID-19—including a sometimes slow availability of clinical lab testing for monkeypox—and preemptively increasing its national surveillance of the deadly social disease.
On Aug. 29, the Hindustan Times reported that in an attempt to slow the spread of monkeypox, India’s central government “has designated 15 viral research and diagnostic laboratories (VRDLs) spread across 13 states to monitor the incidence of monkeypox in the country.”
In the United States, the disease has spread with alarming speed, reaching all 50 states, as well as Washington, DC, and Puerto Rico. At 23,893 confirmed cases as of Sept. 14, the US now has the most cases in the world, according to the federal Centers for Disease Control and Prevention (CDC).
Reuters reported on Aug. 4 that the US Department of Health and Human Services (HHS) had declared a public health emergency. It was in May when monkeypox was detected in the United Kingdom (UK). Both the UK and several countries in Europe have struggled to control spread of the disease.
India hopes its decision to designate 15 VRDLs across 13 states to monitor the disease’s spread will enable it to do a better job than other countries at containing or eradicating monkeypox in the nation of 1.4 billion people, the Hindustan Times reported.
“The probability of containment is diminishing daily,” American infectious disease epidemiologist Anne Rimoin, PhD, a monkeypox expert at the UCLA Fielding School of Public Health, told STAT. “It’s really unfortunate because we do have the tools. This is not an unknown virus … We have vaccines that are already available, even vaccines with indications for monkeypox. Therapeutics. And we know what’s needed to be done.’’ Clinical laboratory testing for monkeypox will certainly increase over the coming months. (Photo copyright: KTLA.)
Keeping Up Their Guard
“Fortunately, India has not seen a surge in cases and the situation here is well under control. However, we cannot drop the guard just as yet. Therefore, a network of VRDLs has been established for surveillance purposes,” a top government expert told the Hindustan Times, seeking anonymity. “It will help pick signs early in case more cases get reported.”
As of Sept. 19, 2022, India reported just 12 cases of monkeypox resulting in one death, while, as noted above, the US had 23,892 confirmed cases and one death, according to CDC statistics. In the UK, confirmed cases totaled 3,552 with no deaths. And, as of that date, the European Union reported 19,379 confirmed cases.
Until recently, monkeypox was endemic only in West and Central Africa. India reported its first case of monkeypox on July 14. So far, most, but not all, of its cases have been related to international travel.
“The isolated cases of monkeypox reported in Delhi with no prior travel history emphasize the importance of tracing the source of the infection, perhaps transmission through rodent population,” Diwakar Kulkarni, PhD, former Director and Principal Scientist at the Indian Council of Agricultural Research, National Institute of High Security Animal Diseases, told Think Global Health.
Homosexuality a Vector in India
While India’s scientists are focused on containing the monkeypox outbreak, the country’s government may encounter societal roadblocks because of the disease’s connection with homosexuality. Gay sex is believed to be fueling the spread of the disease, ABC News reported. Until a Supreme Court of India ruling in 2018, gay sex was punishable by up to 10 years in prison in India.
Virologist and noted HIV expert Ishwar Gilada, MD, who opened India’s first AIDS clinic in 1986, told Bloomberg “anti-gay stigma” in India is causing male patients to avoid getting tested and treated for the disease. He said even before the first monkeypox cases were reported in India, two of his patients—a gay man and a man who identified as bisexual—refused to get tested because they feared being the first monkeypox case in the country.
“They are going underground,” Gilada told Bloomberg.
Did the US Wait Too Long to Begin Testing for Monkeypox?
The rapid growth in cases worldwide and the geographic spread of the disease has left global health experts pessimistic monkeypox can be contained.
NPR reported in June that some experts believe public health agencies ran too few tests in the early months of the outbreak because state health officials used a narrow definition of monkeypox when determining who qualified for testing, and that the US had “dropped the ball” on monkeypox testing.
As of Sept. 19, 2022, there were 62,406 confirmed cases worldwide, according to the CDC.
As clinical laboratories attempt to recover from the workload created by the COVID-19 pandemic, monkeypox appears to be the next endemic to test the mettle of lab professionals. Only time will tell if America and other western nations failed to act as expeditiously as India in curbing spread of this latest deadly disease.
Officials also worry about diminishing smallpox vaccinations, which offered people protection against the infectious disease
Monkeypox challenges from the current outbreak have dogged public health agencies even though the disease was first identified more than 50 years ago. That is because the virus has found new avenues of infection. These developments will be relevant for the nation’s clinical laboratories, which are often the first healthcare providers to confirm a suspected case is positive for monkeypox and notify a public health laboratory about the positive test result.
The latest monkeypox numbers from the federal Centers for Disease Control and Prevention (CDC) indicate that, as of September 6, the US has identified 19,962 cases in the 2022 outbreak, while worldwide the case number is 52,037.
In “When It Comes to Monkeypox Testing, Clinical Laboratories Should Be Aware of Five Significant Developments,” Dark Daily wrote about steps being taken to identify and control infections in America as well as trends in medical laboratory testing for monkeypox. This included reports of phlebotomists refusing to draw monkeypox blood samples and how social stigma surrounding the disease can affect who gets a medical laboratory test.
Workers at clinical laboratories and anatomic pathology groups will gain from understanding why monkeypox has spread beyond its traditional geography.
“Monkeypox symptoms include swollen lymph nodes, fever, and body aches that result in red bumps on hands, feet, mouth, and genitals,” Bodhraj Acharya, PhD (above), of the Laboratory Alliance of Central New York, told Dark Daily. “It spreads by close contact, respiratory droplets, lesions, and bodily fluids.” Clinical laboratories engaged in testing for monkeypox will want to stay alert to patients presenting with such symptoms.

African Public Health Officials Saw New Monkeypox Challenges Coming
Researchers and public health experts have been perplexed about how and why the latest monkeypox outbreak has occurred so aggressively beyond its origin in rural Central Africa.
“Monkeypox is caused by the pox virus, with a close resemblance to smallpox,” said Bodhraj Acharya, PhD, Manager of Chemistry and Referral Testing at the Laboratory Alliance of Central New York, in a conversation with Dark Daily. “Unlike COVID-19, this is an old enemy which has roots in the 1970s from Congo, when the disease was erratically endemic in Africa.”
According to the World Health Organization (WHO), most monkeypox cases since 1970 have been reported from rural rainforest regions in Central and Western Africa.
Thus, a monkeypox outbreak occurring in Europe and the United States in 2022 has puzzled virologists and microbiologists because it does not follow the historical pattern of the virus’ spread. For example, the first monkeypox case in the US arrived in May from a Massachusetts patient who had traveled to Canada, a state press release noted.
Before the Nigerian outbreak, the virus rose from rural areas where hunters came in close contact with animals. The illness resulted in lesions on the face, hands, and feet, Nature wrote of Yinka-Ogunleye’s recollections.
However, after 2017, she and other epidemiologists warned peers that the virus was spreading in new ways and in urban settings. For example, infected people sometimes had genital lesions, suggesting that the virus might spread through human sexual contact.
Now, in 2022, “the world is paying the price for not having responded adequately” in 2017, Yinka-Ogunleye told Nature.
Lack of Smallpox Vaccination Increases Monkeypox Challenges
The waning effects of smallpox vaccinations, which ended in 1980 after smallpox was basically eradicated from the world, may have opened the door for monkeypox to spread earlier this year. Smallpox vaccines provided some protection against monkeypox, but by now three generations of people have not received smallpox inoculations.
“Eyebrows were raised when multiple cases of monkeypox were reported from various non-endemic countries starting in May of 2022,” Acharya said. “Due to genetic similarity, smallpox vaccination provided some cross-protection, but the termination of smallpox vaccination could have provided ground for the recent insurgence and spread of monkeypox.”
Trying to jumpstart a new monkeypox vaccination campaign on the heels of COVID-19 shots may be met with resistance from a virus-weary public. But other options at preventing the current spread of monkeypox may present challenges as well, such as trying to curtail sexual activity among affected population, the BBC reported.
“The easiest way to prevent it is to close down all highly active sexual networks for a couple of months until it goes away, but I don’t think that will ever happen. Do you?” Paul Hunter, PhD, Professor of Medicine at the University of East Anglia in Norwich, England, told the BBC.
For medical laboratory workers and others who may find themselves testing for the disease in the future, the biggest lessons from current monkeypox challenges are twofold: The virus has invaded new geography, and discontinued smallpox vaccination campaigns may have left younger people exposed to monkeypox.
There are reports of phlebotomists refusing to draw monkeypox blood samples and social stigma surrounding the disease can affect who gets a medical laboratory test
Cases of monkeypox are increasing in the US—14,115 as of Aug. 19, up 1,400 from the prior week—and clinical laboratories around the country are bracing for a potential increase in monkeypox testing orders.
Several factors, however, are affecting the testing. Chief among them:
Lab workers refusing to take blood draws from potential monkeypox patients, and
Community clinics in some cities having to delay other care to deal with an onslaught of monkeypox test orders.
Here are five trends clinical laboratory leaders should be aware of that are influencing the state of monkeypox testing in the country.
Trend 1: Some Phlebotomists Refuse to Draw Possible Monkeypox Specimens
CNN reported that phlebotomists at two of the largest commercial laboratories—Labcorp and Quest Diagnostics—were either refusing or being told not to draw blood samples from suspected monkeypox patients.
“Labcorp and Quest don’t dispute that, in many cases, their phlebotomists are not taking blood from possible monkeypox patients,” according to CNN. “What remains unclear, after company statements and follow-ups from CNN, is whether the phlebotomists are refusing on their own to take blood or if it is the company policy that prevents them. The two testing giants say they’re reviewing their safety policies and procedures for their employees.”
In “Medical Laboratories Respond to Monkeypox Outbreak Using CDC-Developed Diagnostic Test,” Dark Daily noted that skin lesion swabbing, such as that necessary to perform the OrthopoxvirusPCR test, is the preferred method to check for monkeypox because of higher viral counts in the lesions. However, physicians may order follow-up blood tests for confirmed monkeypox patients, and suspected patients may need bloodwork as part of other routine care.
In an update posted on its website, Quest noted it has been testing swab specimens of skin lesions for monkeypox, but those swabs are performed by providers and not Quest. However, the company was also preparing to take blood draws of possible monkeypox patients in its patient service centers.
“Given that monkeypox has been declared a national public health emergency and the most recent CDC guidance, we are now implementing procedures to safely enable patients with suspected or confirmed monkeypox infection into our patient service sites for phlebotomy blood draws and other non-swab specimen collections,” Quest stated. “This approach will enable patients with suspected or confirmed monkeypox infections to receive additional testing they may need.”
Trend 2: Guidance Is Available to Help Lab Workers Avoid Monkeypox Infection
The CDC has posted guidance to maintain infection control around suspected monkeypox specimens. Among the steps noted by the agency:
Lesion specimens from patients suspected of having monkeypox will carry the highest quantity of the virus. When possible, lab workers that have a smallpox vaccination from within the last three years should handle these specimens. Smallpox vaccination also protects from monkeypox in many cases. Unvaccinated workers who test suspected monkeypox specimens need to take extra precautions, such as wearing a buttoned lab coat, gloves, and face protection, and avoiding splashes, the CDC stated.
Blood specimens draw from suspected monkeypox patients will have a low quantity of the virus. Lab workers testing these specimens do not need to be vaccinated for monkeypox, but standard precautions should be followed.
Before using automated testing platforms with suspected monkeypox specimens, labs should conduct a risk assessment to identify potential hazards.
Trend 3: Monkeypox Testing Gains an Early Social Stigma
Some people who need to be tested for monkeypox may be hesitant to seek out a medical laboratory or patient service center because of a stigma being attached to the disease.
Although it does not match the early hysteria associated with HIV infections in the 1980s—in a 1987 poll, 60% of respondents said AIDS patients should carry a card identifying them as such, Gallup noted—there have been clear instances where people and agencies have associated monkeypox infection with men having sex with other men.
“The focus for all countries must be engaging and empowering communities of men who have sex with men to reduce the risk of infection and onward transmission, to provide care for those infected, and to safeguard human rights and dignity,” Tedros Adhanom Ghebreyesus, PhD, the Director-General at the World Health Organization, said in a July 27 media briefing.
Ghebreyesus added that while 98% of monkeypox infections have been among men who have sex with men, anyone can get the disease, including children.
“Stigma and discrimination can be as dangerous as any virus, and can fuel the outbreak,” said Tedros Adhanom Ghebreyesus, PhD (above), Director-General at the World Health Organization (WHO), in a media briefing. Clinical laboratories would be wise to prepare for a marked increase in demand for monkeypox testing. (Photo Copyright: WHO/Christopher Black.)
“Men who have sex with men have been hit the hardest by monkeypox to date, but LGBTQ+ health advocates say improper messaging risks branding monkeypox as a ‘gay disease,’ eroding effective preventive measures and allowing the virus to spread,” Bloomberg Law reported.
For example, 66% of respondents either were not sure or did not believe there is a vaccine for monkeypox.
Trend 4: Workers Who Refuse to Test Patients for Monkeypox Face Possible Backlash
Some medical professionals have raised concerns about healthcare workers being unwilling to test monkeypox patients.
“This is absolutely inexcusable. It’s a grave dereliction of duty,” David Harvey, Executive Director of the National Coalition of STD Directors, told CNN. The group represents sexually transmitted disease (STD) directors at public health departments in the US.
“For every single patient that walks [through] your door, you use universal precautions because every disease doesn’t have a phenotype or outward appearance, so you have to treat everyone exactly the same,” Garfield Clunie, MD, president of the National Medical Association and Assistant Professor of Obstetrics, Gynecology, and Reproductive Science at the Icahn School of Medicine at Mount Sinai, told Bloomberg Law. “You can’t treat someone differently because of their sexual orientation, or race, or gender, or for any other reason.”
Trend 5: Public Clinics Show Early Signs of Monkeypox Testing Pressure
A survey of 80 public health departments conducted by the National Coalition of STD Directors indicated that some sites may already be getting overwhelmed by demand for monkeypox testing.
According to the survey results, 79% of public health clinics saw an increased demand for monkeypox testing over the past four weeks. In a troubling aspect, 28% of clinics said they could not meet testing demand if it increases.
Further, 22% of clinics have reduced screenings for other STDs to prioritize monkeypox testing. Such moves likely delay patients from receiving other care they need.
Clinical laboratories may want to take note of the survey findings. The pressure public health clinics currently face could be a precursor to similar problems at labs if demand for monkeypox testing grows.
The federal agency shipped tests to five commercial clinical laboratory companies, augmenting efforts by public health labs
Medical laboratories in the US are ramping up their efforts to respond to an outbreak of monkeypox that has been spreading around the globe. Microbiologists and clinical laboratory scientists will be interested to learn that this infectious agent—which is new to the US—may be establishing itself in the wild rodent population in this country. If proved to be true, it means Americans would be at risk of infection from contact with rodents as well as other people.
The Centers for Disease Control and Prevention (CDC) announced on May 18 that it had identified the infection in a Massachusetts resident who had recently traveled to Canada. As of August 3, the federal agency was reporting 6,617 confirmed cases in the US.
“Because there are no other non-variola orthopoxviruses circulating in the US, a positive test result is presumed to be monkeypox,” states the APHL press release.
“As we focus on the US response, we keep a close watch on the global outbreak. Infectious diseases don’t respect borders, as we know,” said Chris Mangal (above), director of public health preparedness and response, APHL, in a press release. “I am proud of how LRN member laboratories have rapidly and effectively responded to this emergency. This is precisely what the LRN was intended to do. Should this outbreak continue to grow, preparing for expanded testing and increasing capacity beyond LRN laboratories is important to ensuring we are ready for a surge in testing.” (Photo copyright: Association of Public Health Laboratories.)
Commercial Labs Get Involved
Seeking to bolster testing capacity, the federal Department of Health and Human Services (HHS) announced on June 22 that the CDC had begun shipping OrthopoxvirusPCR tests to five commercial lab companies. They include:
“By dramatically expanding the number of testing locations throughout the country, we are making it possible for anyone who needs to be tested to do so,” said HHS Secretary Xavier Becerra in an HHS press release.
Labcorp was first out of the gate, announcing on July 6 that it was offering the CDC-developed test for its customers, as well as accepting overflow from public labs. “We will initially perform all monkeypox testing in our main North Carolina lab and have the capacity to expand to other locations nationwide should the need arise,” said Labcorp chief medical officer and president Brian Caveney, MD, in a press release.
Mayo Clinic Laboratories followed suit on July 11, announcing that the clinic’s Department of Laboratory Medicine and Pathology would perform the testing at its main facility in Rochester, Minnesota.
“Patients can access testing through Mayo Clinic healthcare professionals and will soon be able to access testing through healthcare professionals who use Mayo Clinic Laboratories as their reference laboratory,” Mayo stated in a press release.
Then, Quest Diagnostics announced on July 13 that it was testing for the virus with an internally developed PCR test, with plans to offer the CDC test in the first half of August.
The lab-developed test “was validated under CLIA federal regulations and is now performed at the company’s advanced laboratory in San Juan Capistrano, Calif.,” Quest stated in a press release.
Public Health Emergency?
Meanwhile, the CDC announced on June 28 that it had established an Emergency Operations Center to respond to the outbreak. A few weeks later, on July 23, World Health Organization (WHO) Secretary-General Tedros Adhanom Ghebreyesus, PhD, declared that the outbreak represented “a public health emergency of international concern.”
He noted that international health regulations required him to consider five elements to make such a declaration.
“WHO’s assessment is that the risk of monkeypox is moderate globally and in all regions, except in the European region where we assess the risk as high,” he said in a WHO news release. “There is also a clear risk of further international spread, although the risk of interference with international traffic remains low for the moment. So, in short, we have an outbreak that has spread around the world rapidly, through new modes of transmission, about which we understand too little, and which meets the criteria in the International Health Regulations.”
Still, public health authorities have made it clear that this is not a repeat of the COVID-19 outbreak.
“Monkeypox virus is a completely different virus than the viruses that cause COVID-19 or measles,” the CDC stated in a June 9 advisory. “It is not known to linger in the air and is not transmitted during short periods of shared airspace. Monkeypox spreads through direct contact with body fluids or sores on the body of someone who has monkeypox, or with direct contact with materials that have touched body fluids or sores, such as clothing or linens. It may also spread through respiratory secretions when people have close, face-to-face contact.”
The New York Times reported that some experts disagreed with the CDC’s assessment that the virus “is not known to linger in the air.” But Professor of Environmental Health Donald Milton, MD, DrPH, of the University of Maryland, told The Times it is still “not nearly as contagious as the coronavirus.”
The Massachusetts resident who tested positive in May was not the first known case of monkeypox in the US, however, previous cases involved travel from countries where the disease is more common. Two cases in 2021—one in Texas and one in Maryland—involved US residents who had recently returned from Nigeria, the CDC reported. And a 2003 outbreak in the Midwest was linked to rodents and other small mammals imported to Texas from Ghana in West Africa.
“Labcorp and Quest don’t dispute that in many cases, their phlebotomists are not taking blood from possible monkeypox patients,” according to CNN. “What remains unclear, after company statements and follow-ups from CNN, is whether the phlebotomists are refusing on their own to take blood or if it is the company policy that prevents them. The two testing giants say they’re reviewing their safety policies and procedures for their employees.”
One symptom of monkeypox, the CDC states, is a rash resembling pimples or blisters. Clinicians are advised that two swabs should be collected from each skin lesion, though “procedures and materials used for collecting specimens may vary depending on the phase of the rash.”
“Effective communication and precautionary measures between specimen collection teams and laboratory staff are essential to maximizing safety when manipulating specimens suspected to contain monkeypox virus,” the CDC notes. “This is especially relevant in hospital settings, where laboratories routinely process specimens from patients with a variety of infectious and/or noninfectious conditions.”
Perhaps the negative reaction to the CDC’s initial response to the COVID-19 outbreak in the US is driving the federal agency’s swift response to this new viral threat. Regardless, clinical laboratories and pathology groups will play a key role in the government’s plan to combat monkeypox in America.
CDC asks physicians and clinical laboratories to be on the lookout and report symptoms of hepatitis to state health departments
Growing incidences of hepatitis in children are perplexing medical professionals and researchers in several countries around the world. The mysterious outbreak is occurring in otherwise healthy children and, to date, is of unknown origin, though an adenovirus may be involved.
Microbiologists and clinical laboratory scientists who perform virology testing may want to prepare for increased numbers of children presenting with hepatitis symptoms in the US.
On April 21, the Centers for Disease Control and Prevention (CDC) issued a nationwide health alert to notify the public about a cluster of children in Alabama who presented with hepatitis and adenovirus infections. The CDC asked physicians to watch for symptoms in children and to inform local and state health departments of any new suspected cases.
Also in April, the World Health Organization (WHO) issued its own alert to an outbreak of acute hepatitis of unknown etiology among young children in several countries. In addition to the United States, cases were reported in the United Kingdom, Spain, Israel, Denmark, Ireland, the Netherlands, Italy, Norway, France, Romania, and Belgium.
All the cases reported to the WHO involved children between one month and 16 years of age with the majority of cases occurring in children under five.
According to NBC News, as of May 19, the worldwide number of cases “under investigation” had reached 600 in more than 25 countries. In the US, more than 90% of the patients required hospitalization and 14% of those patients needed a liver transplant. The CDC is investigating five pediatric deaths that may be attributed to the mysterious hepatitis outbreak.
“Fifteen days ago, CDC issued a nationwide health alert to notify clinicians and public health authorities about an investigation involving nine children in Alabama identified between October of 2021 and February of 2022 with hepatitis or inflammation of the liver and adenovirus infection,” said pediatrician and epidemiologist Jay Butler, MD (above), Deputy Director for Infectious Diseases at the CDC. “We’re casting a broad net to increase our understanding,” he added. “As we learn more, we’ll share additional information and updates.” Hospital-based clinical laboratories that support emergency departments and urgent care centers with testing for hepatitis will want to monitor for upcoming CDC alerts.

Adenovirus/SARS-CoV-2 May Be Linked to Hepatitis Outbreak
The cause of the hepatitis outbreak is as yet undetermined, but the pre-eminent theory among disease experts points to the presence of an adenovirus, which often causes cold and flu-like symptoms in addition to stomach issues.
NBC News reported that more than half of the US patients, 72% of the UK patients, and 60% of the affected patients across Europe tested positive for human adenovirus type 41. This virus, however, is generally not associated with hepatitis in healthy children, and rarely impacts the liver so severely.
Medical experts are also considering the possibility that COVID-19 infections could somehow be an underlying cause since the hepatitis outbreak occurred during the pandemic. The WHO is investigating whether exposure to the SARS-CoV-2 coronavirus might have prompted the immune systems in the infected children to react abnormally to adenoviruses that are typically non-life threatening.
“The big focus over the next week is really looking at the serological testing for previous exposure and infections with COVID,” Phillipa Easterbrook, MD, a senior scientist at the WHO headquarters in Geneva, told NBC News.
Hepatitis, or inflammation of the liver, is typically caused by heavy alcohol use, exposure to toxins, certain medical conditions and medications, or a virus.
The most recent children diagnosed with hepatitis presented with some or most of these symptoms, particularly stomach issues and fatigue. However, one symptom was present in all the children.
“The big symptom that made all of these kids different was that they all showed signs of jaundice, which is the yellowish coloration of the skin and eyes,” Markus Buchfellner, MD, a pediatric infectious disease fellow at the University of Alabama, told NBC News.
Buchfellner was the first person in the US to notice an unusual pattern of hepatitis among children. He reported his findings to the CDC last fall in 2021.
“We were able to uncover the possible association with the adenovirus 41 strain because it is our standard practice to screen patients diagnosed with hepatitis for adenovirus,” he said. “For us to dig deeper into this medical mystery and see if this strain is the cause of these severe hepatitis cases, we first need more data on how widespread the outbreak is.”
Adenovirus 41 is usually spread through fecal matter, which makes hand washing critical, especially after visits to the bathroom or diaper changes. This type of adenovirus typically presents as diarrhea, vomiting, and fever, and is often accompanied by respiratory issues.
Clinical Labs Performing Gene Sequencing Can Help
Medical scientists around the world are responding to this threat to the youngest and most vulnerable among us. Research is underway into identifying additional cases, determining what is causing the hepatitis globally among children, and establishing preventative measures.
Pathologists and clinical laboratory managers in the US will want to be on the alert for positive hepatitis tests in children whose specimens were tested at their facilities. With advances in gene sequencing that make testing economical and expeditious, more labs have the ability to not only detect hepatitis, but also to identify any genetic variants that may be associated with the increased number of pediatric hepatitis cases appearing around the world.
