Malaria is the most significant and deadly tropical mosquito-borne parasitic disease in the world, infecting up to 1 billion people across 109 nations in Africa, Asia, and Latin America. The spread of malaria by female Anopheles mosquitoes, particularly in the subtropics, will play a significant role in reducing the disease’s negative effects. This article focuses on the reasons why mosquitoes are more prevalent during the rainy season, the effects of climate change on diseases spread by mosquitoes, like malaria, as well as the control measures that should have been employed to control the spread of malaria.
Why does the rainy season have a higher malaria mosquito population?
During the rainy season, there is humidity in the air, which is a good environment for mosquito breeding. This is because regions with a lot of rain may turn rivers into a network of pools that mosquitoes prefer as their preferred breeding grounds. Remember, warm temperatures, erratic rainfall patterns, and humidity have a significant impact on the lifespan of the mosquito, the development of malaria parasites in the mosquito, and ultimately the transmission of malaria. In order to safeguard yourself from illnesses associated with the rainy season, it is advised to keep all of the doors and windows closed during the rainy season, especially at night.
How is the transmission of malaria affected by climatic variation?
Climate change, in particular the ongoing rise in temperature, will increase the rates of disease spread by mosquitoes and widen their geographic range. And it should be emphasized that a rise in temperature, rainfall, and humidity may encourage the growth of malaria-carrying mosquitoes at higher altitudes, which would lead to an increase in malaria transmission in previously unreported areas. Besides, warmer temperatures will change the mosquito parasite’s growth cycle, allowing it to mature more quickly, increasing transmission and impacting the burden of the disease in lower altitudes where malaria is already a problem.
However, knowledge of the mechanisms underlying the association between malaria and climate change is still incomplete as a result of the complexity of this relationship.
Which preventive strategy has been used to halt malaria’s spread?
The World Health Organization’s malaria control strategy places a strong emphasis on surveillance and readiness. The other areas of focus have included selective vector control, capacity building to prevent epidemics, and prompt, effective treatment in addition to early diagnosis and treatment.
New initiatives like the WHO’s “Roll Back Malaria” campaign, the creation of the Global Fund to Fight AIDS, Tuberculosis, and Malaria, as well as the inclusion of malarial indicators, have all contributed to a resurgence in interest in malaria control. These innovations include dipsticks for diagnosis, artemisinins for the treatment of malaria, and insecticide-treated nets for the prevention of transmission.
