Over the 4 months of this year, the branch of the National Center of Expertise in the Kostanay region received 772 samples with suspected measles for research.
Using enzyme immunoassay, virologists identified 551 positive results.
According to experts, there are also adults among the sick, but children predominate in the age structure of the sick.
During the same period last year, the branch examined only 10 samples, of which only 2 samples turned out to be positive.
Today, the region has seen a gradual decline in the incidence of measles.
