How are these cases distributed across Dhaka?
There are a greater number of cases reported in Moghbazar, Rampura, Jatrabari , Malibag than other areas in Dhaka city.
The Aedes aegypti mosquito is the primary vector of dengue. The virus is transmitted to humans through the bites of infected female mosquitoes. The dengue mosquito can breed in just a teaspoon of standing or stagnant water. The Aedes aegypti mosquito lives in urban habitats and breeds mostly in man-made containers. Common breeding areas are discarded tires, barrels, plastic drums and jerry cans. Unlike other mosquitoes Ae. aegypti is a day-time feeder; its peak biting periods are early in the morning and in the evening before dusk.
“Cities like Dhaka, where development is taking place in an unplanned manner, the grounds are ripe for mosquitoes to breed and procreate.”Bangladeshi urban planner Dr Sarwar Jahan told Al Jazeera.

The incidence of dengue has grown dramatically around the world in recent decades. (WHO, https://www.who.int/news-room/fact-sheets/detail/dengue-and-severe-dengue). This is the case for Bangladesh as well.
Usually, the first cases of dengue are reported in late May or June and go away by late August or early September. However, this year, the number of reported cases begin in January and drastically increased in 2019.
Who is the data source?
These data are sourced from the Institute of Epidemiology Disease Control and Research
The present Institute of Epidemiology, Disease Control and Research (IEDCR) were established in 1976. The institute conducts research on epidemiological and communicable diseases and runs disease control programs mainly in the form of parasitic and entomological containment of vector-borne diseases through the application of epidemiological principles. For example, in recent years, they have conducted tuberculosis prevalence survey, a national serosurvey of dengue exposure in Bangladesh and estimated the incidence of maternal deaths from HEV in Bangladesh. Other activities include surveillance, outbreak investigation and training and workshops on related issues.
