You’re right, this disease is very contagious.
Infectious mononucleosis is a viral disease. Since it is caused by a virus, and not a bacterium, it should immediately be said that the use of any antibiotic is completely pointless. But this is often done, as the disease is often confused with tonsillitis.
Unfortunately, once ill, will become a carrier of the virus for life.
In most cases, the infection is transmitted by airborne droplets: during conversation, crying, crying, sneezing and coughing. But there are other ways in which infected saliva and biological fluids can enter the body:
kissing, sexual way;
through toys, especially those that have been in the mouth of a child – a virus carrier;
through the transfusion of donor blood, if the donor is the carrier of the virus.
Susceptibility to infectious mononucleosis is universal. This may seem incredible, but most healthy people are infected with this virus, and are carriers. In underdeveloped countries, where there is a high population density, this occurs in toddlers, and in developed countries – in adolescence.
Increase and severe edema of the tonsils, with the appearance of loose deposits, or sore throat. They even close, making breathing difficult. The patient’s mouth is open, nasal, puffiness of the posterior pharyngeal wall (pharyngitis).
Almost always increases the spleen and liver. This symptom of infectious mononucleosis in children is noted quite often, and it is well pronounced. Sometimes there are pains in the side and right upper quadrant, mild icterus and increased activity of enzymes: ALT, AST. It is nothing but benign hepatitis, which soon passes.
Picture of peripheral blood. Of course, the patient does not complain about this, but the unique originality of the results of the tests requires that this symptom be indicated as the main symptom: against a background of moderate or high leukocytosis (15-30), the number of lymphocytes and monocytes increases to 90%, of which almost half are atypical mononuclear cells. This sign gradually disappears, and a month later the blood “calms down.”
Approximately 25% of patients have a different rash: tubercles, spots, spots, small hemorrhages. The rash does not disturb, appears at the end of the period of initial appearances, and disappears without a trace in 3-6 days.
Consequences of mononucleosis
After infection, mononucleosis remains resistant immunity. There are no repeated cases of the disease. In the form of rare exceptions, mononucleosis can be fatal, but it can be caused by complications that have little to do with the development of the virus in the body: it can be obstruction and edema of the respiratory tract, bleeding due to rupture of the liver or spleen, or the development of encephalitis.
I hope it answered your question, and I can say – if you kiss the virus carrier, most likely, you can get sick yourself.
I wish you best of luck.
