Dengue cases may increase in the rainy season as some 182 people were infected with the mosquito virus and two died of the disease in the capital during its off-period, health experts said.
They have advised city-dwellers to remain cautious about dengue infection as the mosquito-borne disease breaks out mainly in urban areas during rainy season.Though dengue infection rate is less in other time, but it may increase during the rainy season, they added.
The experts have advised urban people to keep the surroundings of their homes and homesteads clean and destroy possible dens of dengue mosquitoes.
According to the report by the Health Emergency Operations Centre and Control Room of Directorate General of Health Services (DGHS), around 185 patients were admitted with dengue infection to different hospitals in the capital from January 1 to May 25 this year.
Of them, two dengue patients died in Asgar Ali Hospital and BRB Hospital in the capital in April this year, the report said.
“The number of dengue infection may increase in the peak season. Dengue cases may increase during this rainy season that usually begins in July,” ASM Alamgir, principal scientific officer of Institute of Epidemiology, Disease Control and Research (IEDCR), told the daily sun.
“We have to remain cautious before the rainy season for prevention of the disease. We have to keep our neighborhoods clean and destroy all possible dens of the Aedes mosquito which is responsible for the disease,” he advised.ASM Alamgir further said if city-dwellers do not remain alert and do not take any preventive measures, these diseases may spread in villages, cities and towns.
Earlier, some 1192 people were infected and two died in November and 293 infected and one died in December in 2018.
In 2018, some 26 patients were infected with dengue virus in January, seven in February, 19 in March, 29 in April, 52 in May, 295 in June, 946 in July, 1796 in August, 3087 in September, 2406 in October, 1192 in November and 293 in December. A total of 26 patients died last year, the DGHS report said.
While talking to the daily sun, some health experts said people are infected with dengue virus in the capital as Aedes mosquitoes responsible for the disease breed mainly in the city.
Although the disease spreads mainly in the rainy season from April to October, it may infect people anytime round the year, the expert also said.
“There are three types of dengue diseases: dengue fever, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS),” Muhammad Shakhawat Hossain, medical officer of the Health Emergency Operations Centre and Control Room, said.
The Aedes mosquito breeds mostly in flower tubs, abandoned cans, pots, cups, and coconut shells containing clean water in and around the houses, particularly in urban areas, he also said. Health experts said the Aedes mosquito, which is responsible for dengue disease, breeds mostly in flower tubs, abandoned cans, pots, cups, and coconut shells containing clean water in and around the houses, particularly in urban areas.
A joint study conducted by the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), in collaboration with some national and international institutions, said the dengue viruses are responsible for over 100 million confounder adjustments.
“Rainfall, temperature, and relative humidity also significantly affected the mean abundance of mosquitoes. Proper use, disposal and recycling of the containers that effectively produce large numbers of Aedes vector mosquitoes may decrease the risk of arbovirus transmission,” it said.
The study observed that plastic drums, plastic buckets, water tanks, clay pots, and flower tubs are producing a large number of Aedes larvae and pupae while the residents of Dhaka use relatively smaller plastic drums, plastic buckets and larger water tanks to store water from piped water source.
