what is mono virus

Mononucleosis, also known as "mono," is a viral infection caused by the Epstein-Barr virus (EBV) . It is often called the "kissing disease" because it is spread through saliva, but it can also be spread by sharing food or drinks with someone who has the virus. The virus has an incubation period of about four to six weeks, although in young children this period may be shorter. Symptoms of mono include extreme fatigue, fever, sore throat, swollen lymph nodes, and a swollen spleen. The symptoms usually appear four to six weeks after being infected with EBV and may last for several weeks. There is no vaccine to protect against mono, but good hygiene practices such as not sharing food, drinks, or personal items like toothbrushes with people who have mono can help prevent its spread. If you suspect you have mono, it is important to see a doctor if your symptoms do not improve on their own in a week or two.
