From 01/18/2023 to 03/22/2023, 1.6% of people subject to testing and vaccination against blood-borne viral hepatitis applied for testing (n=208). Of these, (n=199) 95.6% of people tested negative and (n=9) 4.5% of people tested positive for viral hepatitis B. Daily load at testing and vaccination sites is very low from 6.2 to 9, 4 people per day.

More women apply for vaccination against parenteral viral hepatitis — 67.7%. Among those who applied for 1-2 vaccinations, the largest share is made up of unemployed 36.8-37.4% (code 120), the second position is occupied by examination for clinical and epidemiological indications — 27.2-26.4% (code 113) and the third position — medical workers 18.1-19.3% (code 118).
