Karnataka Health Minister K Sudhakar on Wednesday said there is no need to panic about reports of tomato flu in neighbouring Kerala, as it is endemic to that State, and instructed authorities in the border district to remain vigilant aimed at controlling its spread.

Tomato flu is a rare viral disease, which causes red-coloured rashes, skin irritation and dehydration, and the disease gets its name from the blisters it causes, which look like tomatoes.
