what is the cause of dengue - #24198
I am feeling really stressed out these days. My cousin just got diagnosed with Dengue last week, and I'm freakin out about it. We were all hanging out together, and now I can’t stop thinking about possible causes of dengue. Like, what is the cause of dengue that could've made him sick? He had the weirdest symptoms, high fever, crazy joint pain, and this awful rash. Honestly, I can't shake the thought that maybe I was exposed too and don't even know it. I mean, is it only from mosquito bites or could there be other things we aren't aware of? I read something that it can be worse for some people... is that true? I'm just wondering, what is the cause of dengue from a medical standpoint? Do we have any control over it? Are there specific places or conditions like standing water that make it worse? If anyone knows and could share that knowledge, I’d really appreciate it. Just want to get a grasp on this cause of dengue thing so I can keep myself and my family safe.

Doctors' responses
Dengue fever is primarily caused by the dengue virus, which is transmitted to humans through the bite of an infected Aedes mosquito, notably the Aedes aegypti and Aedes albopictus species. These mosquitoes are generally found in tropical and subtropical climates worldwide, and they’re most active during daylight hours. The virus can’t spread directly from person to person, so the primary mode of transmission remains mosquito bites. When a mosquito bites a person already infected with the dengue virus, it can become a carrier and then spread the virus to the next person it bites.
Apart from mosquito bites, there aren’t other common ways for the dengue virus to spread. However, certain conditions can exacerbate the situation, like standing water. These environments offer ideal breeding grounds for the Aedes mosquitoes. Decreasing standing water around where you live can definitely help minimize the risk. Things like unused tires, buckets, and plant saucers can collect rainwater and become mosquito breeding sites, so it’s good practice to check and empty these regularly.
Regarding the symptoms you’re worried about, you’re right that dengue can present with high fever, severe joint and muscle pain, rash, and other symptoms. In some cases, especially on subsequent infections with a different serotype of the virus, it can lead to a more severe form called dengue hemorrhagic fever or dengue shock syndrome, which are more serious and require immediate medical attention. If you develop similar symptoms or have concerns about being exposed, it’s crucial to seek medical advice promptly to rule out dengue or receive the appropriate care. Stay aware of outbreaks in your area, follow local health advisories, and use mosquito repellent and protective clothing, especially during peak mosquito activity times, to reduce your risk of dengue.
