Dengue Outbreak: The place Are We At?


An outbreak is the sudden appearance of something undesirable like illness. Dengue fever is a viral infection that is transmitted through the bite of an infected mosquito. Dengue fever is characterized by sudden high fever, severe headache, pain behind the eyes, and pain in muscles and joints. Some may also have a rash and varying degrees of bleeding from different parts of the body, including the nose, mouth, and gums, or bruising on the skin.

The symptomatic illness can vary from dengue fever to more severe hemorrhagic dengue fever. Dengue hemorrhagic fever is a more severe form that only affects a small proportion of those infected. Dengue shock syndrome is a dangerous complication of dengue infection and is associated with high mortality. Severe dengue fever occurs as a result of a secondary infection with a different virus serotype.

Dengue fever and other mosquito-borne diseases such as malaria, Zika virus, chikungunya, and yellow fever mainly spread during the monsoons and post-monsoons.

People faced with any of the symptoms should rush to a doctor and have the necessary tests done and follow the doctor’s instructions. You should also get adequate rest and increase your fluid intake. Always keep dengue infected patients covered with a mosquito net to prevent it from spreading. Use a mosquito net to protect uninfected people, if possible, during the day.

Rapid and unplanned urbanization, the living conditions for the urban poor, and the lack of sanitation all contribute to an increasing number of people suffering from vector-borne diseases. Different awareness campaigns and campaigns need to be run on different platforms and health systems are strengthened to cope with the increasing numbers of dengue patients. This year the dengue fever outbreak could become alarming in Bangladesh, where panic is raging everywhere due to COVID-19. While the dengue season usually peaks from May, mosquito density in the capital has multiplied compared to last year when the country experienced the worst dengue outbreak in history.

The primary preventive measure to reduce dengue infections is to control mosquito populations. The transmission of dengue requires mosquitoes as vectors. A practical and recommended strategy for environmental management is to eliminate unnecessary container habitats where water such as plastic jars, bottles, cans, tires, and buckets can build up for mosquitoes to lay their eggs in. When container habitats are removed and water storage tanks covered to prevent mosquitoes from entering them, mosquitoes have fewer opportunities to lay eggs and cannot develop during their life cycle.

Source reduction can be effective when done regularly, especially when members of a community are mobilized and educated about vector control. Environmental management initiatives can also include important changes in a community, such as: B. the installation of water systems with direct connections to residential buildings and the replacement of wells and other water storage tanks that can be habitats for the mosquito brood. Smaller environmental changes can also be effective. For example, mosquito populations can be reduced if all members of a community clear clogged gutters and street gullies and keep their yards free of containers of standing water.

In Bangladesh, the dengue outbreak was unprecedented last year. But we need to understand that there is no alternative but to raise awareness about the destruction of mosquito breeding grounds in order to end the dengue threat.

Climate change and changing precipitation patterns as well as humidity lead to longer breeding periods for mosquitoes and a shortening of the incubation period for diseases. As a result, dengue epidemics are becoming much more unpredictable in terms of the time and place of their occurrence and their extent, and are overwhelming our health system already burdened with COVID-19.
