MEASLES AT THE PRESENT STAGE

Abstract

Relevance: Measles is an acute viral infection, the most "contagious" among childhood infections. The causative agent of measles is an RNA virus of the genus morbillivirus of the paramyxovirus family , which has a spherical shape and a diameter of 120-230 nm . The measles virus is not stable in the external environment, quickly dies outside the human body, remains active in the air and on surfaces for up to 2 hours, is not resistant to environmental factors, and quickly dies from sunlight and UV rays. Measles is one of the most contagious diseases in the world, with a contagiousness index of over 90%. Perhaps intrauterine infection ( transplacental transmission), when a woman falls ill at the end of pregnancy, the child is born with signs of measles. Measles during pregnancy is a high risk factor for preterm birth, spontaneous abortion, and the development of congenital malformations . In the absence of anti-measles antibodies in the mother, the child may become ill in the neonatal period .
