How can a 5 year old get mono?

A 5-year-old can get mononucleosis, commonly known as mono, primarily through the Epstein-Barr virus (EBV), which is often transmitted via saliva. This can happen through activities such as sharing drinks, utensils, or close contact with an infected person. While mono is more commonly seen in adolescents and young adults, younger children can contract it as well, sometimes without showing significant symptoms. It's important to practice good hygiene to reduce the risk of transmission.
