Infectious disease screening is a process used to identify individuals who may be infected with contagious diseases, such as HIV, tuberculosis, or hepatitis. This screening often involves tests, questionnaires, or physical examinations to detect the presence of pathogens or antibodies in the body. Early detection can help prevent the spread of diseases and allow for timely treatment. Screening is typically recommended for high-risk populations, such as those with multiple sexual partners or individuals with weakened immune systems. Public health initiatives often promote regular screening to ensure community health and safety, reducing the overall burden of infectious diseases.
