Kerala Chief Minister Pinarayi Vijayan has said that the state will conduct a seroprevalence study on the Nipah virus being repeatedly found in Kozhikode district.
According to WHO, population-based seroprevalence surveys are conducted to predict the proportion of infection and immunity in order to comprehend disease burden, a pattern of transmission, and associated risk factors.
The Chief Minister said that the Indian Council of Medical Research (ICMR) is not providing a clear answer to why the virus outbreak repeatedly happens in Kozhikode, ANI report said.
“So the state has decided to conduct a sero survey. Have asked the health department to prepare a detailed proposal for this,” CM Vijayan was quoted in the report as having said in Thiruvananthapuram.

The entire health system of the state is involved in this initiative with utmost caution,” he said, the report mentioned.
The CM also added that scientific precautions have been taken to prevent the spread of Nipah in Kozhikode as well as neighbouring Kannur, Wayanad, and Malappuram districts, it said.
