Who is At Risk?

People who are most at risk include those with compromised immune systems, such as people living with HIV, malnutrition or diabetes, or people who use tobacco.

When a person develops active TB disease, the symptoms – cough, fever, night sweats, weight loss etc. – may be mild for many months. This poses a risk for others around them if the person is not diagnosed until the disease has progressed and symptoms have worsened.

People with active TB can infect 10-15 other people through close contact over the course of a year. Without proper treatment, 45% of HIV-negative people with TB on average and nearly all HIV-positive people with TB will die.
