What should you know about chikungunya and dengue fever?

Both illnesses are spread by infected mosquitoes and can begin with a sudden fever and feeling unwell. Chikungunya often presents with prominent joint pain, sometimes affecting several joints and making movement difficult. Dengue can also cause severe aches, headache, nausea, or a rash, and some people develop easy bruising or bleeding. These patterns are clues rather than a diagnosis.

Recent travel, mosquito exposure, symptoms in household members, medicines, pregnancy, and existing health conditions help a clinician judge risk. A person can be ill without having every listed symptom, and an early examination may need follow-up as the illness changes.

Rest, drink fluids regularly, and monitor temperature, urine output, alertness, rash, bruising, and pain. Prevent further mosquito bites by using suitable repellent, wearing covering clothing, and using screens or a bed net; this reduces the chance of passing infection back to mosquitoes. Before taking pain or fever medicine, ask a clinician or pharmacist which option is appropriate, particularly if dengue is possible.

Arrange a GP consultation for fever after travel or mosquito exposure, especially when joint pain is marked or symptoms are worsening. Mention the places visited and the date symptoms began. Avoid donating blood until a healthcare professional confirms it is safe.

Seek urgent care for severe abdominal pain, repeated vomiting, bleeding, easy bruising with deterioration, difficulty breathing, fainting, confusion, extreme sleepiness, inability to drink, or much less urine. Fever that settles while the person becomes more unwell also needs urgent assessment. Babies, older adults, pregnant people, and anyone with significant medical conditions should seek advice early rather than waiting for symptoms to become severe.

Ask which illness is most concerning, whether blood tests or repeat assessment are needed, which pain medicines are suitable, how much fluid is appropriate, how to protect others from mosquito bites, and which warning signs should prompt emergency care.
