Infectious mononucleosis is an infective disease caused by Epstein-Barr virus. The most frequent symptoms include sore throat, fever, fatigue, weight loss, malaise, and pharyngeal inflammation.
Enlarged lymph nodes, enlarged liver or an enlarged spleen might be present, too. The infected person can infect someone else when the symptoms appear, which is usually 4 to 7 weeks after the infection. Infection is no longer possible when the symptoms disappear.
Immunity to mononucleosis is developed in people that were infected before. However, there are reported cases of reinfection, although these cases are extremely rare.
Avoiding the usual ways of transmission (kissing, sharing utensils or a toothbrush) is recommended until all the symptoms disappear in the infected person.
You might want to visit a specialist in infective diseases for additional information.
