I. The theme urgency

Diphtheria is an acute infectious disease caused by Corynebacterium diphtheria and characterized by the appearance of a fibrinous membrane on the site of pathogen invasion, which can spread on to the tonsils, larynx and pharynx, leading to symptoms of toxemia and toxic lesions of the cardiovascular system, nervous system, adrenal glands and kidneys.

Infectious mononucleosis (Filatov’s disease) is an acute feverish viral disease, being spread by air-droplet route. It is characterized by polyadenitis (especially cervical one), acute membranous tonsillitis, enlarged liver and spleen, leukocytosis, limphocytosis, presence of atypical lymphocytes. The pathogen of the disease is Epstein-Barr virus (EBV), which contains DNA. EBV is isolated in other diseases: such as Burkitt’s lymphoma and nasopharyngeal carcinoma.

Mumps remains endemic in many countries throughout the world, and mumps vaccine is used in only 57% of countries that belong to the World Health Organization, predominantly in countries with more developed economies. As in the prevaccine era, most cases of mumps are still in children ages 5 to 14, but the proportion of young adults who become infected has been rising slowly over the last two decades. Mumps infections are uncommon in children younger than 1 year old. Death due to mumps is rare; more than half of the fatalities occur in persons older than 19 years.
