Public health experts said that maintaining hygiene and other preventive measures for COVID-19 has helped in keeping away cases of vector borne diseases. Former director of Public Health Dr K Kolandaisamy said that prioritising cleanliness and hygiene in view of coronavirus has helped in reducing the cases of mosquito borne diseases and influenza. “However, the State needs to track vector borne diseases simultaneously to prevent any sudden spike or outbreak,” said Dr Kolandaisamy.
