Indian scientists confirm new dengue virus in Tamil Nadu
Scientists at Pune-based National Institute of Virology have spotted a new genetic variant of the existing dengue virus in Tamil Nadu. The DENV-1 virus was responsible for outbreaks in Tamil Nadu in 2012 and Kerala in 2013, scientists said. The mosquito-borne virus is said to have entered into India from Singapore, where it was associated with severe epidemics in 2005.
