The rise in dengue cases in many parts of the country is attributed to the climate crisis and excessive intermittent rains this year, stated Indian Council of Medical Research (ICMR) director Regional Medical Research Centre, Gorakhpur, Dr Rajnikant Srivastava.

“We have witnessed excessive rainfall, which is causing imosquito breeding sites in flowerpots, tyres and coolers,” Srivastava said.

According to data from the US Centers for Disease Control and Prevention (CDC), around 400 million people get infected with dengue each year. About 100 million get sick. Outbreaks have occurred in Southeast Asia, the Western Pacific, the Eastern Mediterranean, the Americas, the Caribbean, and Africa.

Dengue viruses are spread to people through the bites of infected mosquitoes, mainly Aedes aegypti mosquitoes.

Dengue is caused by one of any of four related viruses: Dengue virus 1, 2, 3, and 4.

Dengue is widespread throughout the tropics, with local variations in risk influenced by rainfall, temperature, relative humidity and unplanned rapid urbanization.
