In Michigan Center, Dr. Rubina Shaikh at Allegiance Family Medicine is diagnosing a few cases of mononucleosis, commonly known as mono or the kissing disease.

Symptoms can remain dormant for four to seven weeks after a person is infected.

One of the first to appear is extreme fatigue. You may also have fever, tenderness in lymph nodes, sore throat, and upset stomach, as well as sweats, swollen eyelids, body swelling, headache and muscle and joint pain.

You may not feel "back to normal" for up to three months.

During that time, get proper rest, drink fluids, and take over-the-counter medications. You can also gargle with warm salt water.

The virus is most common in people between the ages of 15 and 35.

Mono is highly contagious and can be spread through kissing, coughing, sneezing, and sharing utensils or some makeup.

Since mononucleosis symptoms can remain dormant for a month or more, the virus can be spread easily.
