According to the airport users, the problem is prevalent both in domestic and international terminals. Passengers claimed that many viruses were spreading across the world and the airport officials were not even able to prevent mosquito breeding in the premises — where thousands of passengers from different countries interact — and it could lead to fever outbreak apart from posing health hazards. “When I went to drop my cousin at the airport one night, I could not even wait for a few minutes as there were so many mosquitos. Officials should take steps to control the menace and should not take it lightly as many diseases may spread among the passengers,” said Kumaresan, an NRI presently residing in Chennai.
