How is infectious mononucleosis typically transmitted?

Infectious mononucleosis, often caused by the Epstein-Barr virus (EBV), is primarily transmitted through saliva, which is why sharing eating utensils with an infected person is the most plausible mode of transmission. Activities such as kissing, sharing drinks, or using the same eating utensils can all facilitate the spread of the virus since it can be present in high concentrations in saliva.

Other modes of transmission, such as through respiratory droplets or contaminated surfaces, are less significant in the spread of this particular virus. Respiratory droplets are more commonly associated with other viral infections, and, while touching contaminated surfaces can contribute to the transmission of many pathogens, it is not a primary route for infectious mononucleosis. Additionally, insect bites do not play a role in transmitting this virus, as it is not vectored by mosquitoes or other insects. Understanding these pathways is important for recognizing how to prevent the spread of infectious mononucleosis, particularly in social settings where close contact occurs.
