Rubella is a viral disease which is famous for its high transmissibility. Most often rubella is caught by not vaccinated children from two to nine years old. It is especially dangerous to get this disease in the first trimester of pregnancy as it promotes development of serious defects in a fetus, and sometimes and provokes his death.
The delivery agent and incubator for rubella virus is human. The virus is transmitted by air, drop way at conversation, etc., and also in direct way from mother to a fetus. The transmission of infection is possible also in the contact way (children’s toys, use subjects, kisses, etc). The infected person is capable to start infecting people around in a week before rashes are shown, and remains dangerous to people around a week more after the first rash. In the child with a congenital rubella the transmissibility remains about three weeks.
The rubella is shown by an eruption in the form of fine maculae, an insignificant feverish state and a hyperadenosis. Viability of this infection is extremely weak, it almost instantly perishes in the environment, weak against acidity change, influence of disinfectants and ultraviolet rays. After the sustained disease human gets the immunity to it on for the rest of the life.
The period of maturing of rubella virus (incubation) from ten days to three weeks; the first symptoms are: rash, insignificant headache and temperature which are felt about three days. Two days after eruption has vanished, the joints’ tumescence is shown which passes approximately in ten days.
