Dengue fever: prevention and control | Deccan Herald

“If you know you have dengue fever, avoid further mosquito bites in the first week of illness. During this time the virus can circulate in the blood and you can therefore spread the virus to new uninfected mosquitoes, which in turn can infect other people, ”warns the World Health Organization (WHO).

Dengue should be suspected if high fever (104 ° F) is accompanied by two of the following symptoms during the fever phase: severe headache, pain behind the eyes, muscle and joint pain, nausea, vomiting, swollen glands, rash.

The proximity of mosquito vector breeding sites to human residential areas is a major risk factor for dengue fever, as well as for other diseases that are transmitted by the Aedes mosquito. The WHO recommends the following measures.

• Prevent mosquitoes from accessing egg-laying habitats through environmental management and modification
• Properly dispose of solid waste and remove artificial, man-made habitats that can hold water
• Cover, drain and clean domestic hot water tanks weekly; Apply appropriate insecticides to outdoor water storage tanks.
• Use personal protection such as window bars, repellants, insecticide treated materials, coils, and vaporizers around the house. These measures must be followed both inside and outside the home during the day as the primary mosquito vectors bite throughout the day.
• Wear clothing that will minimize skin exposure to mosquitoes.
• Engage with the community to increase participation and mobilization for sustainable vector control.
• Spray insecticides as an emergency vector control measure.
• Actively monitor vector abundance and species composition to determine the effectiveness of control measures.
