At least 27 people have so far been diagnosed with dengue in Bangladesh's capital city Dhaka since July 1, Xinhua reported. Six people were admitted to different hospitals in the capital Wednesday with dengue infection, Nasim-us-Seraj, the chief entomologist of Dhaka City Corporation (DCC) was quoted as saying. Nasim said the DCC has been in close contact with hospitals and clinics in the city since July 1 to keep record of the mosquito-borne disease dengue cases. In the middle of the breeding season of Aedes, the dengue-carrying mosquito, everyone needs to use mosquito nets when going to bed, even during the daytime, Nasim cautioned. Entomologist Touhid Uddin Ahmed said the present pattern of monsoon rain creates a suitable atmosphere for Aedes mosquito to breed rapidly. In 2001-2006, dengue fever killed 130 people in Bangladesh. Andin 2006 a total of 1,423 people in Dhaka were infected with the disease and four of them died. There is no treatment for dengue, which can cause high fever, rash, headache, and severe muscle and joint pains. A more severe form can cause hemorrhagic fever.
