How Long Does Mono Last?

How long does mono last? First, let's define what mono is. Mononucleosis, “mono,” or the “kissing disease” is caused by the Epstien- Barr virus. This virus is spread through secretion around the face including the nose, eyes, and mouth. Mono is most common with teenagers and is often identified by fatigue, swollen glands, sore throat and flu like symptoms. A swollen spleen can also be a symptom of mono and in extreme cases it has been known to rupture.

Incubation It takes anywhere between 4 to 7 weeks for mono to show symptoms. During the incubation period the disease can still be spread even though the person may be unaware that they even have the virus.

How long do symptoms last? Symptoms can last anywhere between 2 weeks to 4 months, in extreme cases it may last even longer.

How long is mono in your system? Mono can be in your system for the rest of your life. The longer that you have the virus, the weaker it becomes. So, even though you may still have the virus in your system it will become dormant after time.

How long is treatment? Treatment for mono is simply rest and relaxation. There are rare cases where anti-viral medications are given but in most cases it takes from anywhere between 2 weeks to 4 months for the symptoms to resolve themselves. Doctors will often prescribe a lot of bed rest, and over the counter fever reducers.

How long am I contagious? People have the potential to spread the virus from the moment that they contract it until 18 months after their symptoms have subsided. For a person to actually be contagious during the entire time is extremely unlikely. Most people are contagious from when they begin to show symptoms until around 6 months after symptoms subside.
