Mononucleosis is a viral infection causing fever, sore throat, and swollen lymph glands, especially in the neck.

Alternative NamesMono; Kissing disease
Causes, incidence, and risk factorsMononucleosis, or mono, is often spread by saliva and close contact. It is known as "the kissing disease," and occurs most often in those age 15 to 17. However, the infection may develop at any age.
Mono is usually linked to the Epstein-Barr virus (EBV), but can also be caused by other organisms such as cytomegalovirus (CMV).
SymptomsMono may begin slowly with fatigue, a general ill feeling, headache, and sore throat. The sore throat slowly gets worse. Your tonsils become swollen and develop a whitish-yellow covering. The lymph nodes in the neck are frequently swollen and painful.
A pink, measles-like rash can occur and is more likely if you take the medicines ampicillin or amoxicillin for a throat infection. (Antibiotics should NOT be given without a positive Strep test.)
Symptoms of mononucleosis include:
Less frequently occurring symptoms include:
During a physical examination, the doctor may find swollen lymph nodes in the front and back of your neck, as well as swollen tonsils with a whitish-yellow covering.
The doctor might also feel a swollen liver or swollen spleen when pushing on your belly. There may be a skin rash.
Blood work often reveals a higher-than-normal white blood cell (WBC) count and unusual-looking white blood cells called atypical lymphocytes, which are seen when blood is examined under a microscope. Atypical lymphocytes and abnormal liver function tests are a hallmark sign of the disease.
The goal of treatment is to relieve symptoms. Medicines such as steroids (prednisone) and antivirals (such as acyclovir) have little or no benefit.
To relieve typical symptoms:
You should also avoid contact sports while the spleen is swollen (to prevent it from rupturing).
Expectations (prognosis)The fever usually drops in 10 days, and swollen lymph glands and spleen heal in 4 weeks. Fatigue usually goes away within a few weeks, but may linger for 2 to 3 months.
ComplicationsThe initial symptoms of mono feel very much like a typical viral illness. It is not necessary to contact a health care provider unless symptoms last longer than 10 days or you develop the following:
Call 911 or go to an emergency room if you develop:
Persons with mononucleosis may be contagious while they have symptoms and for up to a few months afterwards. How long someone with the disease is contagious varies. The virus can live for several hours outside the body. Avoid kissing or sharing utensils if you or someone close to you has mono.

No. Mononucleosis (Mono) is a virus.
That is the correct spelling of "mononucleosis" (a viral disease).
mononucleosis is not infectious
An infectious disease specialist can evaluate mononucleosis.

It is called mononucleosis because the virus causes unusual proliferation of monocytes in the blood.
Mono is short for mononucleosis.

how many people get mononucleosis per year and whats the normal age to get it?
A mononucleosis spot (or Monospot) test is a blood test used to determine whether or not you are infected with the Epstein-Barr virus, which is the organism that causes infectious mononucleosis.
Between the ages of 10 and 20. Mononucleosis is caused by the Epstein-barr virus (EBV). People usually get mononucleosis before the age of 20 or at the moment they contract the virus.
