What Is Mononucleosis?
3. Symptoms
As mentioned, the symptoms of mononucleosis are unlikely to cause any real harm, although they can be uncomfortable. One of the most common symptoms of the disease is a sore throat. This will sometimes lead to mono being mis-diagnosed as something else. Other common symptoms include fever and a headache.
Tonsillitis is another potential symptom, while the patient might also have swollen lymph nodes. In some cases, the patient will also develop a rash. The spleen can also become swollen in some cases. Symptoms will usually take between 4-6 weeks to show after infection, but it may be sooner in young children.
