During the last couple of days, eight people with dengue symptoms have been admitted to Dhaka Medical College Hospital, Holy Family Red Crescent Hospital, Ibn Sina Hospital and Central Hospital.

However, six out of the eight dengue-infected patients were released from the hospitals.

The patients reside in the areas of PWD colony, Malibagh, Mohammadpur, Tikatuli, Basabo and Keraniganj.

According to Nasimus Siraj, chief entomologist of Dhaka City Corporation (DCC), fumigation drives are on in the city to combat the situation and the DCC is monitoring the situation.

DCC also intends to launch a mass awareness campaign to clean up all areas in the city and destroy breeding places of dengue-bearing mosquitoes. Volunteers and boy scouts have been requested to help the DCC with the campaign, he added.

In last six years, Bangladesh raised concerns over the outbreak of dengue fever, which has killed 130 people. A total of 1,423 people in Dhaka were infected with the disease and four of them died in 2006.

Warmer weather and heavy rains help the mosquito-borne virus spread through the region. 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.

Aedes, the dengue-carrying mosquito, breed in stagnant water in houses, construction sites, schools and factories.
