Glandular fever is caused by the Epstein-Barr virus (EBV). This virus is found in the saliva of infected people and can be spread through: kissing – glandular fever is often referred to as the "kissing disease" exposure to coughs and sneezes sharing eating and drinking utensils, such as cups, glasses and unwashed cutlery EBV may be found in the saliva of someone who has had glandular fever for several months after their symptoms pass, and some people may continue to have the virus in their saliva on and off for years. If you have EBV, it's a good idea to take steps to avoid infecting others while you are ill, such as not kissing other people, but there's no need no need to avoid all contact with others as the chances of passing on the infection are generally low.
