Glandular fever is a self-limiting sickness which is caused by Epstein-Barr virus. It is also known as infectious mononucleosis. Following a recovery from this illness, the patient is usually immune to it for a lifetime due to the antibodies produced by the immune system during recovery. So, it is rare to contract the fever after going through the first episode.
Young adults and teenagers are common customers of glandular fever. Symptoms vary from a usual headache to sore throat and fever to swollen glands in the armpits or on the neck. It takes 4-8 weeks to incubate and is mainly spread by close contact – kissing, coughing, sneezing, and sharing things (cups, glasses, etc).
