What are the symptoms? Mono comes with a common string of symptoms such as a high fever, sore throat, muscle aches, swollen glands (especially the tonsils) and a complete lack of energy. It usually takes about four to six weeks to show symptoms after being exposed to mono. It may seem like you have the flu or strep throat because the symptoms are so much alike, so it's important to confirm you have mono by visiting a doctor. Your doctor will most likely do a physical exam and a blood test. Most people's symptoms last a few weeks, but it takes several months to recover fully.
How long is mono contagious? Even though you may not have anymore of the symptoms, the virus stays in your saliva for months after your initial infection. Therefore, if you've had mono, experts recommend not sharing lip makeup, cups or other objects that may contain your saliva for about six months after you start feeling better. In addition, most doctors suggest avoiding kissing during that period. A person can be infected with the virus for months before any symptoms appear, so it's also possible to have mono and accidentally spread it to others.
