Fever, cough, a runny nose, sore throat, body ache, and weakness are common symptoms—but they do not always have the same cause.
Depending on the history, examination, season, exposure, and local disease patterns, a clinician may need to consider viral respiratory illness, dengue, malaria, typhoid, tuberculosis, pneumonia, or another infection. The purpose of an assessment is to identify the likely cause, decide whether investigations are needed, and avoid unnecessary medicines.
When a consultation becomes important
Seek medical advice when:
- fever persists for several days or repeatedly returns;
- symptoms improve and then become worse again;
- there is persistent cough, increasing weakness, weight loss, or dehydration;
- breathing becomes difficult or unusually fast;
- there is chest pain, confusion, fainting, or another severe symptom;
- platelet counts are falling or a test result is concerning; or
- the patient is older, pregnant, immunocompromised, or living with a chronic illness.
Do not treat every fever in the same way
Taking only a fever-reducing medicine may temporarily lower the temperature without addressing the cause. Antibiotics are not effective against viral infections and should not be taken without an appropriate prescription.
Rest, hydration, and monitoring can be useful for mild illnesses, but a worsening or prolonged illness needs review.
