how dengue is caused

Dengue is indeed transmitted through mosquito bites, specifically those of the Aedes aegypti and Aedes albopictus species, which are common in many tropical and subtropical areas. When these mosquitoes bite an infected person, they become carriers and can then transmit the virus to others. It’s understandable to be concerned given your recent symptoms and travel history. Dengue often presents with symptoms like high fever, severe headache, pain behind the eyes, joint and muscle pain, rash, and mild bleeding (like nose or gum bleed). The fever and rash you’re describing could align with this, but it’s crucial to get a definitive diagnosis from a healthcare professional through proper tests, as symptoms can overlap with other viral illnesses such as Zika or chikungunya. Since dengue doesn’t typically have a direct treatment, management focuses on relieving symptoms. It’s usually recommended to rest, stay hydrated, and use paracetamol (acetaminophen) for pain and fever—avoid aspirin or ibuprofen as they can increase bleeding risk. Dehydration is a concern, so drinking plenty of fluids like water or oral rehydration solutions is advisable. If symptoms worsen, like experiencing severe abdominal pain, persistent vomiting, or bleeding, or if you feel very weak, it’s important to seek immediate medical attention, as these can be signs of dengue hemorrhagic fever, a more severe form. Regarding your other concern, if you catch dengue once, it’s possible to get it again since there are four different virus types that cause dengue. Immunity to the first type doesn’t protect against others; in fact, a subsequent infection increases the risk of more serious complications. It’s advisable to avoid mosquito-prone areas or use protective measures like insect repellent, mosquito nets, and wearing long sleeves or pants to prevent bites. Always monitor and follow up with your doctor, ensuring your signs are assessed properly. As you focus on recovery, having a detailed medical consultation will further clarify your condition and the next steps.
