cause of dengue - #16291

Tanmay

I am kinda freaking out because my brother just got diagnosed with dengue. He’s been really sick for a week now, fever and terrible joint pains! I'm trying to figure out the cause of dengue since none of us really know how he contracted it. We went to a family gathering at a park, and it was pretty humid, with a lot of mosquitoes around. I keep recalling all those times our parents used to tell us to be careful about mosquito bites, but I thought we were safe because we usually put repellent on. Now, looking back, I we didn’t reapply it often enough – kinda sloppy on our part. The doctor said it's spread by Aedes mosquitoes, but how exactly can we avoid this in the future? Like, are there specific times or places we should absolutely avoid? Can just one bite from an infected mosquito really lead to dengue? Pretty scared for my brother, honestly. Also, how long does it usually take for symptoms to show after getting bitten? I read somewhere it can be anywhere from a few days to two weeks, and that just makes it more nerve-racking. Trying to make sense of this whole thing and want to help protect my family! What do you all think is the best way to educate ourselves on the cause of dengue?

Doctors’ responses

Dengue fever is indeed spread by Aedes mosquitoes, specifically Aedes aegypti and Aedes albopictus. These mosquitoes are more active during the day, particularly during early morning and late afternoon, which are peak biting times. Your suspicion about the humid park with mosquitoes does make sense; these insects thrive in warm, tropical, and subtropical climates and can breed in standing water in containers, which are common in such environments. Even a single bite from an infected mosquito can transmit dengue, making protective measures crucial. To reduce your risk, using mosquito repellent on exposed skin and clothes, wearing long sleeves and pants, and ensuring window and door screens are intact will help. At home, removing or covering water containers can prevent breeding. Symptoms usually emerge 4 to 10 days after an infected mosquito bite, so your brother’s timeline seems consistent with this incubation period. In terms of education, understanding the cycle of the Aedes mosquito and avoiding environments where they breed or are known to be active is key. Local health authorities often provide guidance during outbreaks, and paying attention to such alerts can keep your family informed about high-risk areas or times. For a comprehensive approach, consider local community resources — they may offer information or programs, especially during peak mosquito seasons.
