There is a newly identified virus in China which causes symptoms that include fever, fatigue, cough, loss of appetite and muscle aches.

The virus is believed to have spread from animals to humans and researchers have begun tracking it in China, with dozens of cases recorded so far, The UK Guardian reports.

No fewer than 35 persons are said to have been infected.

Similarly, the novel coronavirus (2019-nCoV, or COVID-19) epidemic first broke out in Wuhan, China before spreading to other parts of the world, killing millions of people.

The novel Langya henipavirus (LayV) was first detected in the northeastern provinces of Shandong and Henan in late 2018 but was only formally identified by scientists last week.

The virus was likely transmitted from animals to humans, scientists said, and Taiwan’s health authority is now monitoring the spread. The researchers tested wild animals and found LayV viral RNA in more than a quarter of 262 shrews, “a finding that suggests that the shrew may be a natural reservoir”. The virus was also detected in 2% of domestic goats and 5% of dogs.

Initial investigations into the virus were outlined in correspondence published by scientists from China, Singapore and Australia in the New England Journal of Medicine (NEJM) last week.

In people, the virus caused symptoms including fever, fatigue, cough, loss of appetite and muscle aches. All of the people infected had a fever, the scientists said. The virus was the only potential pathogen found in 26 of the 35 people, suggesting that “LayV was the cause of febrile illness”.

There have been no deaths from LayV to date. Prof Wang Linfa of the Duke-NUS Medical School, a co-author of the NEJM paper, told the state-run Global Times that the LayV cases had “not been fatal or very serious” so far and that there was “no need for panic”.

It was still unclear whether the virus can be transmitted between people, researchers said. Most of the 35 cases were in farmers, and other infected individuals included factory workers.

Contact tracing of nine patients with 15 close-contact family members revealed no close-contact LayV transmission, but our sample size was too small to determine the status of human-to-human transmission,” the researchers found.

Scientists sequenced the LayV genome and determined it is a henipavirus, a category of zoonotic RNA viruses that also includes Hendra virus and Nipah virus. Hendra virus – which affects horses and humans and originated in Australia – and Nipah virus – which has caused disease outbreaks in south-east Asia – have both been associated with high fatality rates.

LayV is most closely related to the Mojiang virus, which was discovered in southern China.

The Taiwan Centers for Disease Control (CDC) announced on Sunday it would implement genome sequencing and surveillance measures for the virus, reported Taiwan’s Central news agency.

Infectious diseases experts have long warned that the climate crisis and the destruction of nature will increase the risk of viruses being transmitted from animals to humans, in events known as “zoonotic spillovers”.
