Background: Hantaviruses are enzootic haemorrhagic fever viruses whose transmission to humans can cause serious illness with mortality rates ranging from 12% to 40%. Objective: This study aimed to estimate the seroprevalence of IgG antibodies against hantaviruses in the Conakry region. Methods: This was a cross-sectional study of suspected haemorrhagic fever cases. Blood samples were analysed at the Guinea Virology Research Center, Conakry, Republic of Guinea. The indirect enzyme-linked immunosorbent assay (Euro-Immun, vector-best, Russia) was used to detect the presence of specific IgG antibodies to hantaviruses according to the manufacturer's instructions. Results: A total of 368 suspected cases of haemorrhagic fever were reported between 2021 and 2022 in public health facilities in Conakry. The seroprevalence of IgG in patients was 8.7% (95% CI: 6.1-12.0). Patients under 30 years of age were the group most affected (14.9%). The seroprevalence of hantaviruses was significantly higher in trades worker (16.0%) than in other socio-professional categories (p<0.001). Patients with fever associated with anorexia and cough had a hantavirus IgG seroprevalence of 45.5% and 28.9% respectively. Conclusion: This study provided serological evidence of hantavirus circulation in the Conakry region. Active surveillance of hantaviruses, including molecular biology and serotyping, would be necessary to improve our understanding of the ecology of circulating hantavirus strains.
