The Ministry of health of Israel reported that the country has seen a significant increase in cases of epidemic parotitis (mumps).
From January 2017 the mumps contracted in Israel 121 people. At the same time for the same period last year there were 18 cases of infection of this disease.
According to experts from the Ministry of health, the reason for the increase in new cases of mumps may consist in weakening the action of the vaccine, as well as in the development of new strains of the virus.
To date, vaccinated against mumps in children are one year of age. There is an opinion that vaccination should be carried out at an earlier age.
Mumps is most common in children 5 to 15 years and is transmitted by airborne droplets. The incubation period of mumps ranges from 11 to 23 days, the patient is contagious in the last days of the incubation period and the course of disease. The main symptoms of mumps – discomfort when chewing, on the second day swelling of the parotid glands (on one or both sides), the saliva almost ceases to stand out.
Painful effects are reduced, on average, on the fifth day of the disease, and a half weeks, the child recovering if there were complications. If the inflammation a few days switched to the second salivary gland, the disease is usually delayed for 2-3 weeks.
After the disease the mumps of any severity develops strong immunity to re-infection is lifelong immunity. 25% of those infected with mumps are asymptomatic and unnoticed by the patient and his family.
Complications of mumps are relatively rare. Among the possible complications – inflammation of the pancreas, testes in boys and ovaries in girls, inflammation of the thyroid, thymus, and breast, inflammation of the meninges (meningitis) and inflammation of the brain tissue (encephalitis).
