Which of the following diseases is primarily transmitted via respiratory droplets?

The correct choice, mumps, is primarily transmitted through respiratory droplets. This means that the virus can spread through the air when an infected person coughs or sneezes, releasing droplets that may be inhaled by others nearby. Understanding the mode of transmission is essential in preventing outbreaks, especially in crowded settings where close contact occurs.

Mumps is an infectious viral disease that specifically affects the salivary glands, and its primary transmission method highlights the importance of vaccination and isolation during outbreaks to protect vulnerable populations.

In contrast, other diseases listed have different transmission pathways. Hepatitis, primarily types A and B, involves fecal-oral transmission or bodily fluids, while staphylococcal infections are typically spread through direct skin contact rather than respiratory droplets. This distinction is crucial for understanding how to control and prevent the spread of various infectious diseases.
