what are the causes of dengue

Dengue fever is primarily caused by the dengue virus, which is transmitted to humans through the bite of infected Aedes mosquitoes, mainly Aedes aegypti and Aedes albopictus. These mosquitoes become carriers of the virus when they bite a person already infected with dengue. Once infected, the mosquito can transmit the virus to other humans for the rest of its life. Since you live in a tropical area, these mosquitoes can breed easily due to the warm and humid climate favorable for their life cycle. While avoiding standing water is a great measure, as this is where these mosquitoes like to breed, it may not be entirely sufficient, given that these mosquitoes can reproduce in incredibly small amounts of water. With high population densities and urbanization, mosquito exposure can rise without you noticing. Additionally, the Aedes mosquitoes are day biters, with peak periods of biting early in the morning and before dusk, which sometimes catches people off guard. Environmental factors, like unplanned urban developments, poor waste management, insufficient sanitation, as well as climate changes, can also enhance mosquito proliferation, increasing risk of transmission. There is currently no specific antiviral treatment for dengue, so prevention is key. It’s crucial to use mosquito repellents and wear long-sleeved clothing to minimize skin exposure. Regular removal of stagnant water from all possible artificial containers remains an essential control measure. Additional tactics, like using mosquito screens and insecticide-treated bed nets, especially in areas with reported dengue cases, can further reduce the risk of mosquito bites. While it’s mostly the vectors that spread dengue, being conscious of your immediate environment and personal measures can help protect you and your family. If you’re ever in doubt or symptoms persist, promptly consulting a healthcare professional can ensure timely diagnosis and management.
