dengue fever is caused by which virus - #17469
I am pretty worried and just want to know dengue fever is caused by which virus. Last week, my sister had what we thought was just a flu, but then she seriously got worse. She had a high fever, severe headaches, and those terrible body pains. We went to the doctor and they mentioned something about dengue fever. I didn't really get it at first, like, how could she get dengue fever when we've never been to a tropical place? Then they did some tests. Turns out, her platelet count was super low! I mean, are there specific viruses that lead to dengue fever? Do we need to be on the lookout for anything specific where we live? 'Cause I keep hearing how dengue fever is caused by which virus but I don't understand if there are more than one strain or anything. My whole family is kinda freaked out now, especially since they keep saying prevention is key, but what does that even mean? Should we all get tested or something? Just trying to figure this out before it gets any worse. Sorry if it sounds scattered, but I'm just really worried!

Doctors' responses
Dengue fever is caused by the dengue virus, which is transmitted primarily through the bite of an infected Aedes mosquito, typically Aedes aegypti. This virus actually consists of four closely related but distinct serotypes, known as DENV-1, DENV-2, DENV-3, and DENV-4. This means a person can potentially be infected up to four times, once with each serotype. You mentioned not traveling to a tropical area, but it’s worth noting that dengue is now found in many areas, even closer to home than you might expect. It’s spread through various regions due to global travel and climate factors expanding the range of these mosquitoes. When it comes to prevention, the focus is mostly on avoiding mosquito bites. This includes using insect repellent, wearing long sleeves and pants if you’re in an area with mosquitoes, and using screens or nets over windows and beds. Eliminate standing water around your home regularly as it can serve as breeding grounds for these mosquitoes. While testing for dengue might not be necessary for everyone, your sister’s lower platelet counts indicate a classic sign of this viral infection, so it’s crucial she follows the healthcare provider’s advice closely. If someone in your household begins to show similar symptoms like high fever or severe headaches, it would be wise to seek medical advice soon. Testing is usually guided by clinical symptoms, especially if there’s known exposure risk. Prevention really revolves around reducing the chance of getting bitten by an infected mosquito and early medical consultation if symptoms arise.
