dengue risk factors - #18257
I am confused about dengue risk factors. Just a few weeks ago, I traveled to a tropical area for a family wedding, and I started feeling sick the day after I returned. At first it seemed like the flu—fever, fatigue, and awful joint pains. But then I read online about dengue and started freaking out, thinking about all the potential dengue risk factors I might've encountered. I was at this beautiful garden for a reception, and there were a lot of mosquitoes around, which had me worried, like, were they carrying the virus? I did do some research and saw that apparently living in a warm and humid environment can increase the risk, and I live in a hot climate too. I don’t know though, is it also true that if you’ve had dengue before, you’re at a higher risk? Ugh, the doctor I saw seemed to brush me off and said it was just a viral infection, but I’m wondering if I should be more worried about these dengue risk factors. I keep thinking, what else should I be looking out for? And, honestly, how can I prevent this in the future? Feeling really anxious about all this and just need some clarity on the dengue risk factors.

Doctors' responses
Dengue fever is indeed transmitted by mosquitoes, specifically Aedes species, which thrive in warm, humid areas. Your exposure in a tropical setting where there were mosquitoes around does place you at risk for dengue, especially if there were Aedes mosquitoes present. Living in a hot climate might slightly increase your chances, but it’s the mosquito bites during the trip that would be the main factor. Yes, if you’ve had dengue before, you have a higher risk of severe dengue if infected again, possibly due to antibody-dependent enhancement, which can complicate your immune response during a subsequent infection. Given your symptoms, it’s important to differentiate between dengue and other conditions like the flu. Dengue typically involves high fever, severe headache, muscle and joint pains (sometimes called “breakbone fever”), rash, mild bleeding, and in some cases, severe symptoms like abdominal pain, persistent vomiting, or bleeding requiring prompt medical attention. You should be vigilant for these severe symptoms, as they necessitate immediate medical evaluation. For prevention, try to reduce mosquito exposure by using repellent, wearing protective clothing, and ensuring windows and doors are screened. Also, eliminate standing water sites where mosquitoes breed. Keeping these mosquito control measures in mind will help minimize future risks. It’s prudent to follow up with a healthcare provider who can evaluate if your symptoms may truly align with dengue or another infection. Blood tests are often used for definitive diagnosis, and the treatment involves supportive care, ensuring you stay hydrated and manage fever and pain. If any severe new symptoms appear, return to your doctor promptly.
