Dengue, the world’s most rapidly spreading mosquito-borne viral disease, is taking a far bigger human toll than was believed to be the case. As many as 390 million people across the globe could be falling victim to the virus each year, according to a multinational study published by Nature on Sunday.
India emerges in the analysis as the country with the world’s highest dengue burden, with about 34 per cent of all such cases occurring here.
According to the World Health Organisation (WHO), incidence of dengue has shot up 30 fold in the past 50 years. Its estimate has been that globally there were 50-100 million dengue infections taking place annually.
