Dengue is a viral infection caused by the bite of an infected Aedes aegypti or albopictus mosquito. Most people recover, but a small number develop severe dengue, which is dangerous. Symptoms include a high fever, severe headache, pain behind the eyes, muscle and joint pain, nausea, and a rash. Dengue is spread by mosquito bites, typically starting 4-10 days after a bite. Home care includes rest and drinking fluids. Paracetamol can be used for fever, but avoid aspirin and ibuprofen due to increased bleeding risk. Seek urgent care if fever lasts more than two days or if warning signs of severe dengue are present. Prevention includes emptying, covering, or scrubbing water containers weekly, covering stored water, using repellent, and wearing long sleeves during the day. Dengue has spread from the Tarai into Kathmandu Valley and hill towns, with cases rising sharply from August to November. Report local outbreaks to your municipality. Red-flag signs include severe tummy pain or repeated vomiting, bleeding gums or nose, blood in vomit or stools, restlessness, cold clammy skin, or drowsiness; fast breathing or feeling faint when standing.
