The dengue situation might worsen in the months of August and September, according to health experts. Despite the government's visible preventive measures, the numbers of cases and fatalities from dengue fever are rising day by day as a record number of dengue cases and deaths were reported in the country in the first six months of this year. According to experts, the pattern of Aedes mosquitoes has changed as it has now become much “smarter” than before. Prof. Dr. Kabirul Bashar, Entomologist of Jahangirnagar University, said, “The dengue situation may worsen in the running month. During our research in the laboratory, we make a model after analyzing some factors, including the density of Aedes mosquito population, number of dengue patients, temperature, humidity and rainfall. It is clear that the dengue situation may worsen in the coming days. It could take a serious turn in the months of August and September.” Dengue death toll rises to 127 with record 13 deaths in 24 hours “At this moment it is important to manage dengue hotspots and use fogging to combat Aedes mosquitoes in those areas where dengue has already spread. In that case, the authorities can detect the infected people through their address and kill the mosquitoes through fogging machines, because as long as these mosquitoes remain alive, dengue will spread in all the areas,” he said. He also urged city dwellers to combat dengue and ensure that Aedes mosquitoes do not accumulate in their homes and yards. 55 wards in Dhaka at high risk According to a survey conducted in 98 wards — under Dhaka North and South city corporations — by the Directorate General of Health Services (DGHS), from June 18 to 27, 55 wards are at high risk of dengue.

Reasons behind deaths from dengue Public health expert Dr Lelin Chowdhury said the country has recorded the highest death toll from dengue in the first six months this year. There are some reasons behind it. First, most of those who were infected with dengue this year, have had dengue once or twice before. When they again became infected with the disease, the severity increased. Most of them failed to identify whether they were infected with dengue or not and some people were in a dilemma. When they delay in seeking medical attention, they develop a condition of complications or shock syndrome, he said, adding, “This is another reason for deaths behind dengue.” DSCC opens control room to check dengue Besides, the behaviour pattern of Aedes mosquitoes has changed as they bite people throughout the day and night, and can remain active in artificial light outside, which is playing a vital role in dengue infection. “We are afraid that if no immediate program is taken against the Aedes mosquito to control dengue, a terrible disaster might be upon us in the coming days,” he said. Replying to a question on why the authorities concerned have not yet managed to control dengue, Dr Lelin said, “The authorities concerned of the city corporations have not taken effective measures as we see. Secondly, it is not possible for the city corporations alone to combat dengue. For this, the public representatives and people should be involved as well.” Prof. Dr Nazmul Islam, director of disease control and line of DGHS, said during a survey conducted on 3149 houses in 40 wards of DNCC and 58 wards of DSCC, Aedes larvae were found in 549 houses, which is an alarming sign. He also blamed people’s unawareness behind the spread of dengue.
