Someone with latent TB infection:

Someone with latent TB infection:

• A. Can infect others
• B. Shows symptoms
• C. Cannot infect others
• D. Is curable using antibiotics

Answer: (C)

Individuals with latent TB infection harbor the bacteria that cause tuberculosis, but they do not exhibit any symptoms and are not contagious. This means that someone with latent TB cannot spread the bacteria to others, which distinguishes them from those with active TB disease, who do show symptoms such as coughing and can transmit the bacteria through the air. Latent TB is a state where the immune system contains the infection, keeping it inactive. While latent TB can be treated and potentially cured with antibiotics, it is important to note that the key factor that confirms it as latent TB is the absence of active disease symptoms and the inability to infect others. Therefore, the characteristic defining someone with latent TB is that they cannot infect others, making this answer the correct choice in the context of the question.
