- Infectious mononucleosis - kissing disease
- Treatment
Infectious mononucleosis - a disease caused by a virus, Epstein-Barr virus or human herpesvirus type 4. It is most common in teenagers, but it can hurt people of any age. Due to the fact that mononucleosis is transmitted through the saliva, it is sometimes also called the "kissing disease."
Causes of infectious mononucleosis
The cause of this disease is Epstein-Barr virus. According to scientists, the virus infected more than 98% of the world population, the vast majority of people are native speakers, have not yet reached the age of 30 years. A significant part of the virus infection does not cause any symptoms.
Most often the disease develops in people aged 15 to 17 years. Infectious mononucleosis in children under two years of relatively rare.
Epstein-Barr virus is transmitted by airborne droplets. Infection can occur, for example when an infected person coughs or sneezes using the same dishes with healthy people, or kissing them. Infection can also occur through blood and semen.

The first signs of infectious mononucleosis appear, on average, four to eight weeks after infection.

It is believed that Epstein - Barr virus lives on various objects, which gets the saliva of an infected person (such as toothbrushes or glasses) as long as they remain moist. While there is no evidence that disinfection helps prevent the spread of the virus, so to prevent this, the patient must use separate utensils to store your toothbrush separate from the others, and so on.
In the first weeks after infection a person can spread it for several weeks, even before they have any symptoms. Regardless of the cause Epstein - Barr virus mononucleosis, or not, it remains in the body in a latent state. If one day the virus is reactivated, people will once again be contagious to others.
Risk groups for the development of infectious mononucleosis include people aged 15 to 25 years, students (especially those who live in dormitories), nurses, employees of kindergartens, people with weakened immune systems.
Symptoms of infectious mononucleosis
According to studies, the symptoms of infectious mononucleosis in adults
Mononucleosis in adults - a rare phenomenon
It appears only in 35-50% of cases of infection with the Epstein - Barr virus. In children, the virus leads to a pronounced signs of disease even rarer. The most common symptoms of mononucleosis
Symptoms of mononucleosis - easy to make a mistake
:
- Drowsiness;
- Heat;
- Malaise;
- Lack of appetite;
- Muscle aches;
- Skin rash;
- A sore throat;
- Swollen lymph nodes;
- Enlargement of the spleen;
- The increase in the liver;
- Lethargy;
- Fatigue.
Symptoms of infectious mononucleosis in children
Mononucleosis in children - possible complications
They tend to be less severe than in adults. In many cases, the disease causes only brief discomfort that parents take for the common cold.
In rare cases, infectious mononucleosis may experience the following symptoms:
- Chest pain;
- Cough;
- Headache;
- Hives;
- Jaundice;
- Nosebleeds;
- Increased heart rate;
- Increased sensitivity to light;
- Shortness of breath.
When you see these symptoms, patients are advised as soon as possible to contact your doctor.
Typically, patients recover mononucleosis 2-4 weeks (although the virus, as already mentioned, remains in the body), but some patients as early as a few weeks or even months may experience unusual weakness and constant fatigue.
Diagnosis of infectious mononucleosis
For the diagnosis of this disease is usually carried out blood tests, during which identifies antibodies (immunoglobulins) to Epstein - Barr virus. IgM type antibody detected only during the active phase of infectious mononucleosis. IgG antibody blood test can identify later, when the patient begins to recover.
Results of analyzes for infectious mononucleosis may simply be positive or negative (the presence or absence of antigens, respectively). They may also be presented in the credits - a conditional value which shows the concentration of antibodies to viruses, bacteria or other pathogens (in the case of mononucleosis - to Epstein - Barr virus) in the material which was analyzed. His talk more precisely, the caption - an indicator of how much you need to dilute the sample, so that it was impossible to detect antibodies. For example, a titer of 1: 8 indicates that the antibodies can be detected when one of the blood diluted by eight portions of brine, but they are not detected when the solution was prepared at a ratio of blood to one part of the solution is sixteen. The larger second number, the higher the concentration of antibodies in the sample.
Blood picture in infectious mononucleosis is usually as follows:
- The level of white blood cells increased slightly, and reaches a peak in the second or third week of the disease;
- Approximately 40% of patients elevated levels of bilirubin in the blood (although jaundice only 5% of patients with mononucleosis);
- The titer of greater than 1: 320 - reliable indicator of active infectious mononucleosis. (Titer more than 1:10, but less than 1: 320 means that the patient is infected with Epstein-Barr virus, but it does not have active mononucleosis, and the titer of at least 1:10 happens to people who are not infected with the virus).
It should be noted that if a person has been infected only a few weeks ago, a blood test for antibodies to the Epstein-Barr virus may give a false-negative result. If the analysis showed the presence of antibodies, but the patient has symptoms associated with mononucleosis, after a time, the analysis need to be repeated. In a patient with very weakened immune systems analysis mononucleosis
