Epstein-Barr Virus

The Epstein-Barr Virus (EBV) is a common virus that belongs to the herpes virus family and is most known for causing glandular fever (also called infectious mononucleosis), especially in teens and young adults. Many people are exposed to EBV in childhood, and although it often causes mild or no symptoms at all, it can lead to fatigue, fever, sore throat, and swollen glands when it becomes active later. EBV spreads mainly through saliva—hence the nickname “the kissing disease”—but it can also be passed through sharing drinks, utensils, or personal items.

 

Once a person is infected, the virus stays in their body for life in a dormant state and may occasionally reactivate without causing symptoms. While there’s no cure for EBV, rest, fluids, and symptom relief are usually enough to recover fully, though fatigue can linger for several weeks. Understanding EBV helps families recognise the symptoms early, manage them effectively, and reduce transmission within the home.
