In 2022, the number of cases of opisthorchiasis morbidity increased in the Novosibirsk Region. This is a parasitic disease caused by flatworms.
According to data provided by the Rospotrebnadzor Office for the region, last year the number of cases was 2,566 people, which is 1,076 more than in 2021, when the incidence was at the level of 1,490 people.
Note that outbreaks of opisthorchiasis transmitted from fish have been recorded in large areas of the former Soviet Union. High rates of infection with an infection that affects the bile ducts, gallbladder and pancreatic ducts are observed in Siberia, as well as in Southeast Asia.
In the first two months of this year, 423 cases of opisthorchiasis were detected in the Novosibirsk Region, which is 175 cases more than in the same period last year, when 248 cases were detected.
As stated in the regional Rospotrebnadzor, last year 95% of patients with acute opisthorchiasis fell ill after eating dried, slightly salted river fish, such as ide, bream and crucian carp, purchased at spontaneous markets.
