Be seen today
Arrange a prompt medical assessment if you have a cough lasting several weeks, especially with fever, night sweats, weight loss, chest pain, or blood-streaked mucus.
You should also seek assessment if you have had close contact with someone diagnosed with active TB, even if you feel well.
