What should you know about causative agent for dengue?

Dengue virus enters the bloodstream after a bite from an infected mosquito. It can cause an illness with fever, headache, muscle aches, joint pain, chills, and sometimes easy bruising. These features can overlap with other infections, so symptoms alone cannot confirm dengue. The virus is not normally passed directly from one person to another through casual contact. Mosquito protection still matters around an unwell person because a mosquito can acquire the virus from blood and spread it onward.

Arrange medical advice when dengue is possible, especially after travel or residence in an area where it circulates. Rest, drink fluids, and record temperature and symptoms. Ask which pain or fever medicines are suitable; avoid starting aspirin or ibuprofen unless a clinician has advised them, because bleeding can be a concern. Use mosquito repellent, long clothing, and screens so mosquitoes are less likely to bite during illness.

Seek urgent care for severe abdominal pain, persistent vomiting, bleeding from the nose or gums, blood in vomit or stool, easy bruising that is increasing, breathing difficulty, extreme weakness, restlessness, drowsiness, or fainting. Warning signs can appear as fever improves, so continue watching symptoms and follow the clinician's plan.

Ask whether testing is needed, which medicines are safe, how to maintain hydration, when blood tests should be repeated, and which symptoms require emergency assessment. Tell the clinician when fever began and where you have recently travelled.
