Kolkata : World Mosquito Day serves as a reminder of the critical role mosquitoes play in the transmission of deadly diseases. These tiny yet dangerous insects act as vectors, transporting infectious pathogens from one host to another. When a mosquito takes a blood meal from an infected person, it becomes a carrier of the pathogen. The next time it bites a non-infected individual; the disease is transmitted, leading to potentially severe health outcomes.
In West Bengal, mosquito-borne diseases remain a significant public health concern, with hundreds of cases reported annually. In 2022 alone, around 38,000 dengue cases were reported in Bengal, with Kolkata among the worst hit (4427 cases). [1]
One of the significant contributors to the increase in mosquito-borne diseases is climate change. Warmer temperatures can accelerate the development and biting rates of mosquitoes, as well as shorten the incubation period of the diseases they carry. Changing rain patterns are also expanding the habitats of mosquitoes, allowing them to thrive in regions where they were previously uncommon. With shorter, warmer winters and extended summers, the prevalence of vector-borne diseases is on the rise.
Understanding how to protect oneself from mosquito bites is crucial. You can use effective mosquito repellents such as lemon eucalyptus, clove, peppermint, and neem oil. Structural barriers like window nets and mosquito nets can also provide additional protection, while long sleeves and full-coverage clothing are recommended for personal safety. Removing potential mosquito habitats and using appropriate pesticides are also key preventive measures.
All age groups are susceptible to mosquito bites, but certain populations are at higher risk of severe disease. Infants, toddlers, and the elderly are particularly vulnerable to the complications associated with mosquito-borne illnesses. As the mosquito season begins, it’s essential to remain vigilant. In the past month alone, around 12-15 cases of mosquito-borne diseases were reported at Fortis Hospital Anandapur. While the season is just starting, there is already an observable increase in cases compared to last year.
There are also several myths and facts about mosquito bites that people should be aware of. For instance, it’s a fact that only female mosquitoes bite and that one mosquito can lay thousands of eggs.
However, contrary to popular belief, mosquitoes do not die after biting a human, and eating certain foods cannot repel mosquitoes naturally.
