[The role of the food transmission factor in the occurrence of 2 hepatitis A outbreaks].

Two outbreaks of virus hepatitis were etiologically and epidemiologically interpreted. In this work the original method of obtaining washings, with their subsequent concentration, from the suspected foodstuff was used and hepatitis A virus was then detected in concentrated washings in the enzyme immunoassay, which made it possible to confirm the contribution of the alimentary factor of the transfer of infection (sun-cured melon) in the above-mentioned outbreaks. The data thus obtained are indicative of the necessity to conduct epidemiological investigation, taking into account the possibility of contacting hepatitis A when using foodstuffs not subjected to preliminary treatment.
