Which age group is most likely to be affected by Tuberculosis?

• A. Children under 5
• B. Adults aged 20-50
• C. Seniors over 65
• D. All age groups equally

Answer: (B)

The age group most likely to be affected by Tuberculosis (TB) is adults aged 20-50 because this demographic often encounters a combination of risk factors that can lead to higher transmission rates. These factors include higher rates of social mobility, living in close proximity with others, and potential exposure to environments where TB is more prevalent, such as crowded living conditions or specific work settings.

Additionally, this age group might have reduced immunity compared to younger children, who often have protective factors in place, such as vaccinations and more robust health care access related to childhood diseases. Seniors also face increased susceptibility, but this is often due to comorbidities and weakened immune systems rather than a direct link to high transmission rates.

While Tuberculosis can affect all age groups, adults aged 20-50 typically show higher incidence rates in epidemiological studies due to social and economic factors that facilitate the spread of infection.
