Health authorities in the southern Indian state of Kerala are on high alert following the latest flare-up of the deadly Nipah virus. It comes after a 14-year-old boy died from an infection over the weekend and as authorities race to track those who came into contact with him. Kerala Health Minister Veena George said Tuesday that the close relatives of the teenager had tested negative for the virus, according to local media reports. She added that precautionary measures such as wearing face masks in public areas could not be lifted yet.
The state’s health minister has previously said that 60 people had been identified as being in the high-risk category of having the disease. All of those identified as high-risk are being tested for the virus. The Nipah virus, which partly inspired the fictional “MEV-1” virus in the 2011 Hollywood film “Contagion,” is considered one of the most dangerous pathogens circulating in the wild.
Lack of Vaccines and Treatment
First identified 25 years ago in Malaysia, Nipah is estimated to have a case fatality rate as high as 75% and has been cited as having the potential to spark another pandemic. There is currently no vaccine to prevent infection and no treatment to cure it. The Nipah virus is transmitted to humans from animals such as fruit bats or pigs. The virus is known to cause a lethal brain-swelling fever in humans. The World Health Organization says human infections can range from asymptomatic infection to acute respiratory infection.
Dr. Roderico H. Ofrin, WHO Representative to India, said Tuesday that the latest Nipah virus outbreak in Kerala appeared to have a “low risk” of further transmission. “Active and extensive contact tracing was carried out by the Kerala government. 60 people had a close contact with the 14-year-old who died and thus were categorized as high-risk contacts. They are all being tested for the virus,” Ofrin told CNBC in an emailed statement. “Considering transmission dynamics of the Nipah virus itself and the current assessment and the caseloads, this outbreak seems to have a low risk of further transmission.”
Factors Contributing to Outbreaks
Dr. Ofrin mentioned that the reason why Nipah virus outbreaks have been detected in Kerala was “multi-factorial” but emphasized that the southern Indian state has an “excellent” system for identifying, detecting, and registering all suspected cases, leading to immediate public health measures. Prior to the latest flare-up, Kerala’s state government had reported four separate Nipah virus outbreaks in the region since 2018. In an investigation published last year, Reuters reported that extensive tree loss and rapid urbanization in Kerala over recent decades had created ideal conditions for the Nipah virus to emerge.
The situation in Kerala regarding the Nipah virus outbreak is concerning, but the prompt response and proactive measures taken by health authorities are commendable. With no vaccine or treatment available for the virus, it is crucial to focus on prevention strategies and containment efforts to prevent further transmission and mitigate the risk of future outbreaks. The identification of high-risk individuals and extensive contact tracing are important steps in controlling the spread of the virus. It is imperative for governments and health organizations to work together in addressing the root causes of these outbreaks and implementing sustainable solutions to protect public health.
