Tuberculosis screening is a process used to detect if a person has been infected with the tuberculosis bacteria. This is important because early detection can help prevent the spread of the disease. Common methods for screening include the Mantoux tuberculin skin test and interferon-gamma release assays (IGRAs), which measure the immune response to the bacteria. Screening is especially recommended for individuals at higher risk, such as those with weakened immune systems, close contacts of infected individuals, or people living in areas with high rates of tuberculosis. Regular screening helps public health officials monitor and control the spread of this infectious disease.
