Already reeling under public health crisis due to rising cases of COVID-19, Kerala has now recorded its first Nipah death in the last three years. On Sunday, state Health Minister Veena George said a 12-year-old boy from Kozhikode
district died due to Nipah virus infection. She added that the Pune National Institute of Virology confirmed the presence of the Nipah virus after testing the samples.
Two state health workers are also exhibiting symptoms
of the infection. Concerned over the possible threat of an outbreak, the Central government rushed a team of the National Centre for Disease Control to Kerala on Sunday. The team will provide technical support in dealing with the Nipah virus.
Back in 2018, the virus had claimed 17 lives in the state.
What is the Nipah virus?
is a zoonotic disease spread by the saliva of fruit bats. According to the World Health Organisation, the Nipah virus infects several animals, including pigs, dogs, and horses, among others, and causes severe disease and death in people. WHO has termed the disease a 'cause of concern for public health'.
Symptoms of the Nipah virus?
According to WHO, Nipah causes a range of illnesses from asymptomatic (subclinical) infection to acute respiratory illness and fatal encephalitis.
Major symptoms of the infection are:-Brain feverRespiratory infectionMuscle painVomitingSore throatDizziness and drowsinessEncephalitis-like neurological illness and seizuresPneumonia
As per WHO guidelines, the symptoms start emerging in the infected 5-14 days after the Nipah virus hits the host. However, in some cases, the incubation period of the virus can go up to 45 days which means that the infected person can remain unaware of the disease and continue to infect others as well.
Active case search in the family, families, village, and areas with similar topography (especially Malappuram).Active contact tracing (for any contacts) during the past 12 days.Strict quarantine of the contacts and isolation of any suspects.Collection and transportation of samples for lab testing.
Given the Nipah virus threat in Kerala
, the Union Health Ministry has issued the following public health measures:-
People can take following measures to minimise the risk of catching the virus:-Wash hands with soap and water frequently.Fruits should be consumed only after washing them properly.Avoid contact with sick animals.Wear protective gear during slaughter and culling of animals.
Diagnosis and treatment
The real-time polymerase chain reaction (RT-PCR) test, PCR test, and virus isolation by cell culture are the major methods to detect the presence of the virus.
As for treatment, the Ribavirin drug is used to treat the Nipah virus. Though, there are no WHO-approved vaccines available to prevent the infection.
In February 2020, Phase I trial of Nipah virus vaccine candidate (HeV-sG-V) started. It is expected to be completed this month.
