“The first human cases of West Nile virus are an important reminder that we all need to take steps to prevent mosquito bites and mosquito breeding,” said Dr. Muntu Davis, L.A.

"The mosquitoes were just eating us alive," he says.

Chikungunya is spread by two types of mosquito, neither of which are present in the UK, so there is no risk on onward infection.

In Gurugram, an upscale suburb just outside Delhi, gleaming SUVs, futuristic skyscrapers and neat apartments stand in stark contrast to nearby mosquito swarms, trash heaps and tarpaulin shanties.

The best way to prevent the virus from spreading is to reduce pools of stagnant water that allow the mosquitoes to breed, according to the World Health Organization.
