The incidence of ixodid tick-borne borreliosis in residents of the Krasnoyarsk territory who suffered COVID-19

A retrospective epidemiological analysis of the incidence of natural focal zoonotic infections among the human population in the Krasnoyarsk Kray showed that the increase in the incidence of ixodid tick-borne borreliosis in 2022 could be caused by an increase in the number of people with post-acute COVID-19 syndrome, who probably have dysregulation of the immune response and increased sensitivity to various pathogens.

There were no significant gender differences in infectious sensitivity to Borrelia in people who underwent COVID-19. At the same time, among people diagnosed with borreliosis, the proportion of women who have previously had COVID-19 is increased. The same happens with tick-borne encephalitis: a higher infectious sensitivity of women to the encephalitis virus is a statistically justified fact in people who have undergone COVID-19.
