On Sunday, a 12-year-old boy succumbed to the virus, and medical experts in the state began checking all the 251 people who had come into contact with the teen.
"There are 38 persons in isolation at Kozhikode Medical College and Hospital, of which 11 have shown symptoms. Samples of eight persons have been sent to [the] Pune NIV (National Institute of Virology) for testing", George stated, as quoted by the national broadcaster NDTV, adding that the condition of those with symptoms is deemed stable.
The Indian Health Ministry ordered that epidemiological surveillance be bolstered and more intensive contact tracing be conducted. Strengthened security measures related to the virus were also introduced in the Kozhikode district, where the boy lived, and in three neighbouring districts.
The nipah virus is carried by fruit bats, and people contract the disease when eating fruit with the saliva of infected animals. The virus is considered by the World Health Organisation as one of the most dangerous in the world, as there are no drugs or vaccines against it. From 40% to 75% of cases of nipah are fatal.
Nipah was found in Indians in the state of West Bengal in 2001, and in Kerala in 2018-2019.
