Glandular Fever (or infectious mononucleosis) is an infection caused by a virus — the Epstein Barr virus. It is sometimes known as the “kissing disease” because the virus can be passed on via saliva. Coughs and sneezes and sharing food utensils can also pass it on. It’s harder to catch than a cold. It is not a sexually transmitted disease. It generally affects teenagers and younger people. A full and quick recovery, without the need to see a doctor is the usual course of events. Some can carry the virus in their body without developing infection. This is harmless. Normally it’s not possible to work out who gave the infection to who. However it is known that the virus is most likely to be passed on whilst the temperature is high, so very close contact, such as kissing, should be avoided at this time. Symptoms develop between 4 and 8 weeks after infection and start with a very severe, sore throat, swollen tonsils, a high temperature and difficulty swallowing. Other symptoms can include: – Tiredness – Loss of appetite – Muscle aches and headaches – Swollen tender glands in the neck and armpits – Skin rash (sometimes associated with antibiotics) – Abdominal pain – No response to antibiotics (given for presumed bacterial throat infection) makes glandular fever more likely. Glandular fever is very difficult to diagnose from other causes of sore throats and tonsillitis. In most cases this does not matter, as symptoms will resolve quickly. There is no treatment that will work
