High prevalence of human coronaviruses in rural and urban Ghana in the post-COVID-19 era.
Article in Frontiers in epidemiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The prevalence and distribution of endemic human coronaviruses (HCoVs) in Ghana remain poorly characterized, particularly in the post-COVID-19 pandemic era. We conducted a cross-sectional molecular and serological survey of 1,000 individuals from five rural and five urban communities in Ghana to assess the prevalence of HCoVs. Reverse transcriptase real-time PCR (RT-qPCR) assays targeted SARS-CoV-2, HCoV-OC43, HCoV-HKU1, HCoV-NL63, and HCoV-229E, while serological assays evaluated IgG antibody responses against SARS-CoV-2, SARS-CoV-1, MERS-CoV, HCoV-OC43, HCoV-HKU1, HCoV-NL63, and HCoV-229E Spike proteins. A broad pan-coronavirus RT-qPCR assay detected HCoV RNA in 6.7% of participants, with SARS-CoV-2 as the most frequent, followed by HCoV-229E, HCoV-HKU1, and HCoV-OC43; HCoV-NL63 was not detected. Serological analyses revealed widespread exposure to SARS-CoV-2, HCoV-OC43, HCoV-229E, and HCoV-HKU1, with a low seroprevalence for HCoV-NL63. Our findings demonstrate ongoing co-circulation of multiple HCoVs in both rural and urban settings in Ghana post Covid-19, suggesting sustained community transmission, increased potential for co-infection, and the need for continued surveillance of endemic and emerging respiratory viruses. The data provides rare insights into the epidemiology of HCoVs in West Africa.
