How is glandular fever contracted?

The infection is caused by the Epstein-Barr virus that's transferred from one person to another in saliva. Kissing is one obvious way by which the disease can be transmitted. But the infection is also spread via airborne droplets.
The incubation period from infection to when the symptoms first appear is between 30 and 50 days.

What are the symptoms of glandular fever?

• It's possible to become infected with this virus and to develop no symptoms. This is referred to as a sub clinical infection.
• Before the disease breaks out, one to two weeks may pass with symptoms that are similar to those of flu.
• A with swollen tonsils that are heavily covered by a white.
• Severe fatigue.
• Muscle pains.
• In 20 per cent of cases: swelling and puffiness may develop around the eyes, settling after one to two days.
• Tendency to sweat.
• Like the lymph glands, your spleen is part of the immune system and can become swollen. If this occurs, it can sometimes be felt below the ribs on the left-hand side of the abdomen and may occasionally cause mild pain.
• Swollen and sore lymph nodes in the neck, armpits and the groin.
• The liver may become enlarged and yellow may develop.

Future prospects

Glandular fever usually takes two to four weeks and resolves itself without complications. In about 3 per cent of all cases, it goes on longer. After having the disease, a person will have lifelong immunity to it – so will not catch it again.
Possible, but rare, complications of glandular fever include the following.

• The respiratory passages may become partially blocked and require a short course of oral steroid therapy to help to reduce the inflammation.
•  requiring antibiotic therapy.
• The spleen may rupture – this happens in 0.1 to 0.2 per cent of all cases.
• Very rarely, the central nervous system may be infected by the virus and can cause complications like or.
• The number of blood platelets may decrease .
• Rarely, the disease may lead on to chronic fatigue.
