Mononucleosis: Symptoms and Causes

Mononucleosis Tegan Parry

Prevention

Mononucleosis is spread through saliva. If you’re infected, you can help prevent spreading the virus to others by not kissing them and by not sharing food, dishes, glasses and utensils until several days after your fever has subsided — and even longer, if possible. The Epstein-Barr virus may persist in your saliva for months after the infection. No vaccine exists to prevent mononucleosis. [9]

Diagnosis

Healthcare providers typically diagnose infectious mononucleosis based on symptoms. Laboratory tests are not usually needed to diagnose infectious mononucleosis. However, specific laboratory tests may be needed to identify the cause of illness in people who do not have a typical case of infectious mononucleosis. The blood work of patients who have infectious mononucleosis due to EBV infection may show:

more white blood cells (lymphocytes) than normalunusual looking white blood cells (atypical lymphocytes)
fewer than normal neutrophils or platelets
abnormal liver function. [10]
