Which virus is transmitted primarily through droplet transmission?

The influenza virus is primarily transmitted through droplet transmission, which occurs when respiratory droplets containing the virus are expelled into the air when an infected person coughs, sneezes, or talks. These droplets can then be inhaled by individuals nearby, facilitating the spread of the virus. This mode of transmission highlights the importance of respiratory hygiene and the use of masks during influenza outbreaks to minimize exposure.

In contrast, measles virus also primarily spreads through droplet transmission, but it can also be spread via airborne routes over longer distances. Clostridium difficile is mainly transmitted through the fecal-oral route and does not involve respiratory droplets. Mycobacterium tuberculosis, while it can be transmitted through droplets, is more accurately described as primarily spreading through airborne transmission over longer distances due to its ability to remain suspended in the air. This distinction emphasizes the specific characteristics of influenza and its direct association with droplet transmission in common respiratory illnesses.
