Health Minister V.S. Sivakumar has requested Union Health Minister Ghulam Nabi Azad to make available the services of the National Institute of Virology, Pune, in conducting an in-depth study of the dengue scenario in Kerala.

The dengue virus types in circulation in the State, any genetic mutations or increased virus virulence, and long-term measures needed to be adopted in the State for effective dengue control should be studied, Mr. Sivakumar said. This would be taken up during the discussions with Union Health Secretary Keshav Desiraju, during his visit to the State on July 12.
