Mono takes around 6 weeks to incubate. A person is contagious throughout this time, from the time of infection until symptoms manifest. Symptoms include fever, headache, body aches, diarrhea, vomiting, and abdominal pain. In addition to the symptoms listed above, people who are infected with Mono may also have abnormal blood tests results. These include elevated levels of proteins in the blood called "antibodies". The more severe the case of Mono is, the longer it will take for these antibodies to be produced. People who are infected but do not show any signs of the disease may still pass on the virus. They could be responsible for spreading Mono within a school or community. There is no treatment for Mono. The aim of management is to control the symptoms and prevent complications. This includes providing adequate nutrition and hydration as well as controlling fever with medications. Mono can be fatal if not treated promptly. Symptoms include high temperatures, headaches, body aches, confusion, and nerve problems. If you are concerned that you or someone you know has Mono, call your doctor immediately.
