Article Synopsis
- A study was conducted to explore syphilis prevalence among migrant craft and manual workers (MCMWs) in Qatar, which make up 60% of the population, focusing on both lifetime and recent infections.
- Analysis involved sera specimens collected during a nationwide SARS-CoV-2 seroprevalence survey, utilizing advanced testing methods to detect syphilis antibodies and recent infections.
- Results showed a lifetime syphilis infection rate of 1.3% and a recent infection rate of 0.09%, with higher infection prevalence noted in older age groups and variations based on nationality and occupation.
Background: This study provides a head-to-head comparison of the protection provided by the BNT162b2 and mRNA-1273 vaccines against SARS-CoV-2 infection and against severe COVID-19, covering primary series and third dose/booster vaccinations over up to 3 years of follow-up, both before and after the emergence of the omicron variant.
Methods: Two national, matched, retrospective cohort studies were conducted on Qatar's vaccinated population from December 16, 2020, to February 18, 2024. Subgroup analyses by pre-vaccination SARS-CoV-2 infection history, as well as sensitivity analyses, were also conducted.
Introduction: Chemical contamination and pollution are an ongoing threat to human health and the environment. The concern over the consequences of chemical exposures at the global level continues to grow. Because resources are constrained, there is a need to prioritize interventions focused on the greatest health impact.

Methods: Between December 1, 2020, and April 11, 2023, a matched case-control study was conducted to investigate the association between 3036 acute stroke cases and 3036 controls drawn from the entire population of Qatar.
Results: The adjusted odds ratio (aOR) for vaccination among cases compared to controls was 0.
Article Synopsis
- A study was conducted on migrant craft and manual workers (CMWs) in Qatar to assess the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among this population, which makes up 60% of the country's workforce.
- Findings showed that current HBV infection prevalence was low at 0.4%, with education and occupation influencing infection rates, while lifetime HCV infection prevalence was 0.8%, with Egyptians having the highest rates at 6.5%.
- The results suggest that while HBV infection is low among CMWs, HCV is present at an intermediate level compared to global and regional statistics, highlighting the need for ongoing monitoring and targeted health initiatives.
