High risk of dengue fever in Basabo, Goran: DGHS study


The Basabo and Goran regions of the capital have the highest prevalence of the Aedes aegypti mosquito, a vector of dengue fever, according to a survey by the Directorate General of Health Services (DGHS) published on Sunday.

The aforementioned areas have the highest Breteau (IB) index of 73.3, followed by the Elephant Road and Science Laboratory neighborhoods (66.7).

The Monsoon Aedes 2021 survey found that 11 areas of Dhaka North and Dhaka South City companies are at risk of increased dengue outbreaks compared to other parts of the city.

The BI, short for Breteau Index, indicates the number of containers of positive larvae per 100 houses inspected. Under normal conditions, the BI of a zone should be less than 20.

Other areas with high IBs are Moghbazar and New Eskaton (56.7), RK Mission Road and Tikatuli (50), Bashundhara Residential Area and Nikunja (48.4), Kalyanpur and Darussalam (46.7), Mirpur 10 and Kazipara (43.3), Mohakhali and Niketan (40), Banasree (40) and Minto Road and Baily Road (40).

Households in these areas had higher Aedes aegypti larval indices.

20 teams from the Centers for Disease Control (CDC) of the DGHS conducted the survey on 100 sites in 98 neighborhoods in the Dhaka North and Dhaka South regions from July 29 to August 7.

Aftabnagar and Merul Badda from Ward 37 in Dhaka North, and Bangshal from Ward 35 in Dhaka South had an IB of zero, suggesting the lowest possible risk of dengue infection in these neighborhoods.

According to the survey, the greatest number of containers with larvae, 44.2%, were found in multi-storey buildings, 25% in simple buildings, 18.2% in buildings under construction, 9.7 % in slums and 3% in vacant lots.

The results were presented at the Monsoon Aedes Survey 2021 dissemination workshop, by Afsana Alamgir Khan, Deputy Program Manager Malaria & Vector Borne Disease Control.
