High Infection Risk Among Health Care Workers During the First SARS-CoV-2 Wave in Niamey, Niger.
Article in Influenza and other respiratory viruses, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIn 2020, the new pathogen SARS-CoV-2 spread fast, causing a pandemic. Health care workers on the frontline were of course highly exposed. This study aims to analyze the risk factors of SARS-CoV-2 infection in HCWs who have been in contact with positive patients in Niger.
methodsA prospective cohort was conducted among HCWs from March 2020 to June 2020 in health facilities in Niamey. A questionnaire was administered at inclusion; RT-PCR testing was performed if clinical signs were present. Serological testing was performed at baseline, Days 15 and 30. Univariate analysis and Cox regression were used.
resultsRegarding inclusion criteria, 129 health care workers were included. The sex ratio (male/female) was 0.82. The participants were mainly physicians (45.7%) and nurses (34.1%). At inclusion, the prevalence of COVID-19 was 34.9%. Only seronegative (n = 84) were followed up; the attack incidence rate for the first month was 440 per 1000 person*month. Regarding the Cox model, the use of alcohol-based hand washing was a protective factor (RR = 0.28, p = 0.01). Furthermore, females were more at risk than males (RR = 2, p-value = 0.049).
conclusionsHCWs in Niger were faced with high infection risk; this should lead decision-makers to (i) enhance training on preventive measures and (ii) boost access to personal protective equipment in emergency and infectious disease wards.
