High dengue outbreak expected in 2022

Health Entomological Officers’ Association President Najith Sumanasena said yesterday that a dengue epidemic has spread across the country with the beto index measuring mosquito densities exceeding 20. He said that although the beto index was planned to be kept below 5, the World Health Organization had prescribed that it should be kept at less than two.

He said that with the increase in the number of Aedes aegypti and Albopictus mosquitoes that spread the dengue virus in the environment these days, the number of dengue cases has also increased. He said that a high dengue epidemic had spread in the country in 2017. He said that the dengue epidemic usually occurs every five years and that an outbreak would occur in 2022.
