"An epidemiologic investigation of each case of hepatitis A was carried out with the filling in of the relevant documentation forms, water samples (centralized water supply, decentralized water supply and water from private aquamats) were examined in each center of infection, and final disinfection was carried out in each center, if desired," the response to the request reads.
The department reported that in addition, laboratory testing of employees of epidemically significant facilities was carried out using the ELISA method. In particular, drinking water supply facilities, including aqua mats, confectioneries, dairy and meat processing plants, markets, and shopping centers. As well as sanitary and virological testing by PCR of washings from vegetables and fruits sold in Vinnytsia city markets to identify the source of the hepatitis A virus pathogen.
The final cause of the hepatitis A outbreak will be established upon its completion.
