How is mononucleosis primarily spread?

• A. Blood transfusion
• B. Saliva and airborne droplets
• C. Direct skin contact
• D. Contaminated food and water

Answer: (B)

Mononucleosis, often referred to as "mono," is primarily caused by the Epstein-Barr virus (EBV), and its most common mode of transmission is through saliva. This is why it is frequently referred to as the "kissing disease," as kissing can easily spread the virus. Additionally, the virus can be present in other bodily fluids, including respiratory secretions, leading to its potential spread through airborne droplets.

The emphasis on saliva transmission highlights the need for caution in activities that facilitate such interactions, especially among adolescents and young adults, who are more frequently affected by mono. Recognizing this means understanding that typical preventive measures can include avoiding sharing drinks, utensils, or engaging in close personal contact with someone who is infected, aiding in infection control and the maintenance of health among peers.
