Seroprevalence and Phylogenetic Characterization of Hepatitis E Virus () in Guinean Pig Population.
Vector Borne Zoonotic Dis
August 2024
Hepatitis E virus (HEV) is transmitted by the fecal route, usually through contaminated water in humans and/or infected animals, especially pigs. The objective of this study was to evaluate the level of anti-HEV antibodies in a panel of pig sera and to identify HEV in pig feces in farms. The presence of HEV antibodies was tested by an in-house ELISA and a commercial ELISA IDvet.

We tested 888 serum samples collected from pigs in Guinea during 2017-2019 (between the 2013-16 epidemic and its resurgence in 2021) by indirect ELISA against the EBOV nucleoprotein. We identified 2 hotspots of possible pig exposure by IgG titer levels: the northern coast had 48.

- Brucellosis, Q fever, and Rift Valley fever are important zoonotic diseases causing economic issues in livestock, particularly in developing African countries like Guinea, where they are often under-reported.
- The study assessed the presence of these diseases in domestic ruminants by analyzing blood samples from over 1,300 animals across 17 areas in Guinea between 2017 and 2019, finding cattle had the highest rates of infection.
- The findings emphasize the need for better monitoring of these diseases in livestock and suggest health screenings for humans in contact with affected animals, advocating for a coordinated One Health approach.
Article Synopsis
- The study tracks the spread of the SARS-CoV-2 virus in Guinea over 1.5 years, highlighting how different clades and variants entered the country primarily via travelers through Conakry.
- It shows that the introduction of these variants occurred progressively over time.
- Emphasizes the importance of genomic sequencing to monitor the virus's evolution and develop effective control measures.
