Tuberculosis, botulism, and streptococcal infections can be spread by which of the following methods?

• A. Consumption of sterile water
• B. Inhalation of contaminated airborne droplets
• C. Exposure to ultraviolet light
• D. Direct contact with infected individuals

Answer: (B)

Verified step by step guidance

1. Identify the diseases mentioned: tuberculosis, botulism, and streptococcal infections, and understand their common modes of transmission.
2. Recall that tuberculosis and streptococcal infections are primarily respiratory diseases, often spread through airborne droplets when an infected person coughs or sneezes.
3. Understand that botulism is typically caused by ingestion of toxins from contaminated food, not by airborne droplets or direct contact.
4. Evaluate each option: consumption of sterile water cannot transmit these diseases; exposure to ultraviolet light is a method of disinfection, not transmission; direct contact can spread some infections but is less common for tuberculosis and streptococcal infections compared to airborne droplets.
5. Conclude that the most accurate common transmission method for tuberculosis and streptococcal infections is inhalation of contaminated airborne droplets.
