Langya virus

A new type of animal-derived Henipavirus has so far infected people in Shandong and Henan provinces of China, official media here reported on Tuesday.

There is currently no vaccine or treatment for Henipavirus and the only treatment is supportive care to manage complications. There is currently no vaccine or treatment for the virus and the only treatment is supportive care to manage complications The cases of Langya henipavirus so far have not been fatal or very serious, so there is no need for panic, Wang Linfa, a Professor in the Programme in Emerging Infectious Diseases at Duke-NUS Medical School who was involved in the study said, adding that it is still a cause for alert as many viruses that exist in nature have unpredictable results when they infect humans.

There are no vaccines or treatments, The Sun reported. They found the virus in 71 of 262 shrews - a small mole-like mammal - surveyed in the two Chinese provinces where the outbreak started, the Daily Mail reported. Both can cause severe and sometimes fatal illnesses.

As nations continue to contain the twin-threat of COVID-19 and monkeypox, there is another zoonotic virus that has made headlines in China.

However, the cases have not been very serious or fatal. However, the CDC has yet not ruled out the possibility of human-to-human transmission. According to the report, Taiwan’s Centres for Disease Control Deputy Director-General Chuang Jen-hsiang said that human-to-human transmission of the virus is yet to be reported.

The authors of the study have underlined that the sample size of their investigation is too small to determine human-to-human transmission. The patients were accompanied by abnormalities of “thrombocytopenia (35%), leukopenia (54%), impaired liver (35%) and kidney (8%) function”, the study noted. In all likelihood, the new virus has jumped from an animal to humans. The types of Henipaviruses that had been identified prior to this included Hendra, Nipah, Cedar, Mojiang and the Ghanaian bat virus. Langya was discovered in eastern China during surveillance testing of patients who had fever along with a recent history of animal exposure. Langya Henipavirus: Almost three years after the novel coronavirus was detected in China, a new zoonotic virus has been discovered in the country’s two eastern provinces with 35 infections identified so far.

The virus is suspected to have jumped from animals to humans in a process called zoonosis and scientists found the LayV viral RNA in over 200 shrews they tested hinting that they could be the natural reservoir of the virus. The virus has reportedly been found in throat swab samples from febrile patients in eastern China. Reports indicate that the early patients of the virus are mainly farmers, who have reported fatigue, cough, loss of appetite, and aches. A new virus outbreak is raising concerns in parts of China as 35 new cases have been reported.

A zoonotic virus Langya has been reported in China, with 35 people infected so far. The new type of Henipavirus has been found in China's Shandong and Henan ...

Henipavirus is a category of zoonotic RNA viruses that also includes Hendra virus and Nipah virus. A correspondence about the new virus by scientists from China, Singapore and Australia has been published in New England Journal of Medicine (NEJM). There have been no deaths from "LayV", as the virus is called by scientists.

Scientists detected another potential zoonotic spillover nearly three years into the coronavirus pandemic, though evidence suggests very low fatality rates.

Among the 35 patients, 26 were found to be infected only with the Langya virus. Two are considered highly virulent and are associated with high case-fatality ratios, according to the U.S. Centers for Disease Control and Prevention. But none of the Langya patients died, the study stated. Over a roughly two-year period, 34 other people were found to have been infected in Shandong and neighboring Henan, with the vast majority being farmers.

Chinese scientists say a new 'LayV' virus that has sickened dozens likely emerged in shrews.

“But it is yet another reminder of the looming threat caused by the many pathogens circulating in populations of wild and domestic animals that have the potential to infect humans.” But the scientists said the sample size of patients is too small to completely rule out human-to-human transmission. The scientists believe that the virus likely emerged in shrews, small mammals, who then passed it on to humans.

There has so far been no evidence of human-to-human transmission of the Langya henipavirus.

These viruses are known to infect humans and cause fatal disease. Most of them were farmers. Advertisement

Less than three years after the outbreak of COVID-19 started in China, the threat of the new animal-borne LayV virus has been identified.

According to the Chinese scientists, contact tracing of 9 patients with 15 close-contact family members revealed no transmission of the virus. But as none of the patients in China had close contact with each other, experts believe that the transmission of the virus from animal to human is still sporadic. The most common symptom of the Langya virus appears to be a fever (experienced by all patients), but those infected with the virus also reported fatigue (54 per cent of patients), loss of appetite (50 per cent), muscle pain (46 per cent), cough (50 per cent), nausea (38 per cent), headache and vomiting (35 per cent) after contracting the virus.

The contagiousness of the virus depends upon its spreadability and contagiousness. The study observed that contact tracing of nine patients with 15-close contact family members showed no close-contact LayV transmission. Besides 35% of the 26 patients, complained of headaches and vomiting. The virus was found in 27 per cent of the shrew subjects, the Deputy DG of CDC stated. Later, it was identified and isolated from the swab sample of one of those patients. According to a serological survey on domesticated animals, it was seen that 2 per cent of the tested goats and 5 per cent of the tested dogs were positive.

Meanwhile, the researchers from Beijing, Singapore and Australia pointed out further investigation is needed to better understand the infection. Tests detected the virus in 27% of shrews, a known vector for similar henipaviruses, suggesting the small, furry mole-like mammals may be a natural reservoir, they said. The newly identified Langya virus, which has infected over three dozen people in China, belongs to the family of deadly Nipah and Hendra viruses, experts pointed out, however, it is still to be known whether the pathogen can be transmitted from person-to-person.

At least 35 patients across 2 Chinese provinces have been infected with the phylogenetically distinct Langya henipavirus (LayV), according to a report in ...

LayV is most closely phylogenetically related to Mojiang henipavirus, a virus with a genome length of 18404 nt originally discovered in southern China. The Langya virus is comprised of 18402 nucleotides with genomic organization identical to other henipaviruses. Though the sample size is small, they suspect Langya virus was hosted by shrews before infecting humans.

Thirty five people are known to have been infected by Langya henipavirus in the Shandong and Henan provinces of China between December 2018 and May 2021.

Nevertheless, he says the most likely source of any future pandemic will be a virus that jumps from animals to humans. The researchers found no evidence of close contact between the people infected with the virus. The researchers mention that some of the infected people had pneumonia, but don’t specify how many or give details on its severity. The researchers tested 25 species of small wild animals for the virus. The Nipah virus, first identified in 1999 in Malaysia, is also part of this genus. The genus includes the Hendra virus, which was first identified in Australia in 1994 and is known to infect humans and horses.

Scientists hypothesize wild shrews may be the 'natural reservoir' for the new Langya henipavirus discovered in eastern China.

The Cedar, Ghanaian and Mojiang viruses have not definitively made the jump to humans. “I don’t think this should make the list.” Most of the infected patients were farmers.

Scientist detected 35 cases of Langya virus, a new henipavirus, over three years. No deaths or person to person transmission has been reported.

With the development of new techniques for identifying viruses, there’s certainly been a global increase in surveillance, and this has accelerated in the past five years," Hudson said. Cooper guessed that people might also get exposed through contact with the droppings of infected animals, but scientists haven't determined that to be true yet. In the case of Hendra virus, the virus is usually passed from bats to horses; it then infects humans through the animals' excretions or bodily fluids. "There are clearly repeated transmission events from what looks to be a common reservoir in shrews," Cooper said. People can catch Nipah virus from bats or pigs through direct contact with the animals, their bodily fluids or contaminated food. She was infected with a henipavirus, a class that includes some dangerous pathogens like Nipah virus, which has a fatality rate of 40% to 75%.

Though the virus has not yet caused any fatalities, it comes from the same family as other deadly viruses.

A new study published in Nature Climate Change this week revealed that climate change is making 218 known infectious diseases more severe. In the report, scientists emphasized the importance of keeping an eye on the spread of the virus. As of now, researchers believe the virus cannot be transmitted from human to human.

The virus is related to Hendra and Nipah viruses. But we don't know whether it spreads from human to human.

This new virus appears to be a close cousin of two other viruses that are significant in humans: Nipah virus and Hendra virus. However, it is thought more recent outbreaks have been due to food contaminated with the urine or saliva of infected bats. Although they found a small number of goats and dogs that may have been infected with the virus in the past, there was more direct evidence a significant proportion of wild shrews were harbouring the virus. The researchers used a modern technique known as metagenomic analysis to find this new virus. Researchers in China first detected this new virus as part of routine surveillance in people with a fever who had reported recent contact with animals. It’s related to Hendra and Nipah viruses, which cause disease in humans.

Langya virus, which can cause fever, fatigue and nausea, found in 35 people in eastern China, researchers say.

The Hendra virus was first identified in Australia in 1999 and has infected seven humans and more than 70 horses. Nipah infection can be fatal, with 40 to 75 percent of infected people dying in past outbreaks. Some patients also had body aches, nausea, vomiting and headaches, they said.

The henipavirus can cause respiratory symptoms and is related to Nipah and Hendra viruses, but cannot spread easily in people.

This suggested that shrews are a reservoir for the virus, passing LayV between themselves “and somehow infecting people here and there by chance”, says Gurley. Still, she notes that she didn’t see anything in the data to “cause alarm from a pandemic-threat perspective”. The LayV genome shows that the virus is most closely related to Mojiang henipavirus, which was first isolated in rats in an abandoned mine in the southern Chinese province of Yunnan in 2012. Most patients said in a questionnaire that they had been exposed to an animal within a month of their symptoms appearing. Researchers say LayV has infected only 35 people since 2018, and none of the cases seems to be linked. The virus was named after a town called Langya, in Shandong, where she was from, says co-author Linfa Wang, a virologist at Duke–National University of Singapore Medical School in Singapore.

Scientists have warned that phenomena such as deforestation might lead to an increase in the risk of contact between wild animals and humans, heightening the spillover risk. According to the US Centers for Disease Control and Prevention, there are as many as half a million viruses with spillover potential that could cause widespread infection among humans. Between then and 2021, 34 more cases were identified, all among farmers, and further researched published last week in the New England Journal of Medicine confirmed the cause was a virus transmitted by shrews—a very small, mole-like mammal typically found on farms.

Langya virus patients reported symptoms that include fever, fatigue, cough, nausea and headaches.

Further investigation is needed to better understand illnesses associated with the virus, according to the researchers in China, Singapore and Australia who were involved in the paper. The infections were found in China's eastern Shandong and central Henan provinces, affecting 35 people, according to a report in the New England Journal of Medicine this month. Dozens of people in China have fallen ill with a new virus that is also found in shrews, a report has said, but there is so far no evidence of human-to-human transmission.
