Among the given options, strep throat and virus infection are examples of diseases that strictly require direct (body) contact for transmission, while influenza is not. Option B is correct answer.
Strep throat and virus infection are both examples of fomite diseases that can be transmitted through direct contact with an infected individual. Strep throat is caused by the bacteria Streptococcus pyogenes, which can be spread through respiratory droplets or by touching surfaces contaminated with the bacteria and then touching the mouth, nose, or eyes. Therefore, direct contact with an infected individual is necessary for transmission.
Similarly, many viral infections, such as the common cold or the flu, can be transmitted through direct contact with respiratory secretions or by touching contaminated surfaces. However, it's important to note that not all viruses strictly require direct contact for transmission. Some viruses, like the influenza virus, can also spread through airborne droplets when an infected person coughs or sneezes, making it possible for transmission to occur even without direct contact.
In summary, strep throat and virus infections are examples of diseases that strictly require direct (body) contact for transmission. Influenza, on the other hand, can be transmitted through both direct contact and airborne droplets.
