How common is fever in tuberculosis?

Tuberculosis can affect different parts of the body. When it affects the lungs, fever may occur with a cough that persists, night sweating, tiredness, reduced appetite, or unintended weight loss. Some people have mild symptoms, while others become more unwell. Fever patterns can vary and may not be present throughout the illness.

A fever does not show that tuberculosis is the cause; many conditions can produce the same symptom. Assessment may include questions about exposure, travel or residence in places where tuberculosis is more common, examination, and tests chosen for the suspected body site.

Contact a healthcare professional if fever continues without a clear explanation, returns repeatedly, or occurs with a persistent cough, night sweating, or unexplained weight loss. Mention any known contact with tuberculosis and any immune-system condition or medicine that may affect your risk.

If tuberculosis is suspected, follow testing and infection-control advice carefully. Do not stop prescribed treatment when you begin to feel better; tuberculosis treatment usually requires a planned combination of medicines and clinical follow-up.

Seek urgent help for severe breathing difficulty, coughing blood, chest pain, confusion, fainting, or inability to drink. If you have been told you may have infectious lung tuberculosis, ask promptly how to reduce close-contact exposure while assessment is arranged.

Could my symptoms require tuberculosis testing? Which tests are appropriate for the body area involved? Should people close to me be assessed, and what should I do while results are pending?
