Which disease is primarily transmitted by aerosolized droplets?

• A. Hepatitis
• B. Meningitis
• C. Human immunodeficiency virus (HIV)
• D. Tuberculosis

Answer: (D)

Tuberculosis is primarily transmitted through aerosolized droplets, making it the correct answer. When a person with active tuberculosis coughs, sneezes, talks, or even breathes, they release tiny droplets containing the bacteria into the air. Other individuals can then inhale these droplets and become infected. This form of transmission highlights the importance of airborne precautions in healthcare settings when dealing with suspected or confirmed cases of tuberculosis. In contrast, hepatitis is generally transmitted through contact with infected blood or bodily fluids, including through sexual contact and sharing needles. Human immunodeficiency virus (HIV) is transmitted mainly through blood, sexual contact, and from mother to child during childbirth or breastfeeding, rather than through the air. Meningitis can be transmitted through both respiratory droplets and direct contact with infected individuals, but it is not primarily classified as an airborne disease like tuberculosis.
