Article Synopsis
- * A survey involving 1,089 unvaccinated participants revealed that 59.7% had experienced COVID-19, with 47.1% of those exhibiting symptoms and 8.6% hospitalized, while 96.2% of asymptomatic cases were not reported.
- * Findings indicate a link between older age and poor self-rated health with increased COVID-19 severity and hospitalization, emphasizing the need for better surveillance to detect asymptomatic infections.
Background: The published estimates of SARS-CoV-2 seroprevalence in Russia are few. The study aimed to assess the SARS-CoV-2 seroprevalence in Arkhangelsk (Northwest Russia), in a year after the start of the pandemic, to evaluate the population adherence to non-pharmaceutical interventions (NPIs), and to investigate characteristics associated with COVID-19 seropositive status.
Methods: We conducted a SARS-CoV-2 seroprevalence study between 24 February and 30 June 2021 involving 1332 adults aged 40-74 years.
Hepatitis C, caused by the hepatitis C virus (HCV), is a major public health issue in Russia. The aim of our study was to assess the seroprevalence of markers of HCV exposure and factors associated with HCV seropositivity among the general population aged 18-39 years in the city of Arkhangelsk, Northwest Russia. A social research agency applied a quota sampling method to recruit study participants using cell phone numbers.

The aim of our study was to assess the prevalence of serological markers of HBV infection, associated factors, and vaccination status among young adults in Arkhangelsk, Northwest Russia. In this cross-sectional, population-based study, we used a quota sampling method to recruit 1243 adults aged 18⁻39 years.

Mother to child transmission causes high morbidity and mortality among infants. Russia is on the brink of a generalized HIV-epidemic, but Arkhangelsk is still a low-prevalence area.
View Article and Find Full Text PDFBackground And Objective: Statistics on healthcare-associated infections (HAIs) in Russia is scarce and has been considered to suffer from underreporting. We assessed the prevalence and changes in the prevalence of HAIs over 5 years and identified factors associated with acquiring HAIs in the pediatric hospital in Arkhangelsk, Northern Russia.
Materials And Methods: Ten cross-sectional studies were conducted in the Arkhangelsk regional pediatric hospital biannually during 2006-2010.
