As rain and thunderstorms are expected in various parts of the country over the next few days, experts warn that the dengue season could extend further this year. The chances of the situation improving in October remain low. According to the Bangladesh Meteorological Department, rain and thunderstorms, accompanied by gusty winds, are likely in Dhaka, Khulna, and Sylhet divisions, with isolated showers expected in other regions, including Rangpur, Rajshahi, Mymensingh, Barishal, and Chattogram.
This weather pattern is expected to continue until Sunday. Prof Kabirul Bashar, an entomologist at Jahangirnagar University, said the ongoing rainy season might extend the dengue season until December or even January. "Although the density of Aedes mosquitoes has remained static in the last two weeks, this level is still enough to spread dengue further," he said.
Prof Bashar emphasised the importance of controlling mosquito breeding sites and managing hotspots to curb the spread of the virus. "Necessary steps must be taken to control Aedes mosquitoes to manage the situation effectively." Entomologist GM Saifur Rahman echoed this sentiment, saying the current pattern of rainfall is highly conducive to Aedes mosquito breeding.
"This type of rain won't wash away mosquito larvae or eggs, so without immediate action, dengue cases in the most vulnerable areas will rise further," he warned. "We do not expect a reduction in cases this month as the rainy season continues," Saifur added. He stres.
