Tuberculosis ( 23 Questions)
Chemoprophylaxis involves using medications to prevent TB infection or its progression in individuals at high risk of exposure. While it is an important strategy, it is not specifically related to administering the BCG vaccine.
Screening for TB involves identifying individuals who are at risk of infection or have active disease through various tests such as tuberculin skin tests and chest X-rays. Although screening is a crucial aspect of TB control, it is not the strategy involving BCG vaccine administration.
Vaccination with the BCG vaccine is an individual-level strategy aimed at providing protection against TB, particularly in infants or children at high risk of TB exposure or infection. The BCG vaccine does not provide complete protection against TB but has been shown to reduce the risk of severe forms of the disease, such as TB meningitis and miliary TB, in children.
Surveillance involves monitoring the incidence and prevalence of TB at the population level. It does not directly involve administering the BCG vaccine to individuals at risk.
Choice A rationale:
Chemoprophylaxis involves using medications to prevent TB infection or its progression in individuals at high risk of exposure. While it is an important strategy, it is not specifically related to administering the BCG vaccine.
Choice B rationale:
Screening for TB involves identifying individuals who are at risk of infection or have active disease through various tests such as tuberculin skin tests and chest X-rays. Although screening is a crucial aspect of TB control, it is not the strategy involving BCG vaccine administration.
Choice C rationale:
Vaccination with the BCG vaccine is an individual-level strategy aimed at providing protection against TB, particularly in infants or children at high risk of TB exposure or infection. The BCG vaccine does not provide complete protection against TB but has been shown to reduce the risk of severe forms of the disease, such as TB meningitis and miliary TB, in children.
Choice D rationale:
Surveillance involves monitoring the incidence and prevalence of TB at the population level. It does not directly involve administering the BCG vaccine to individuals at risk.
