Article Synopsis
- Nigeria reported its first mpox cases in nearly 40 years five years before the 2022-2023 outbreak, with ongoing human-to-human transmission driving the epidemic.
- Researchers analyzed 112 mpox virus genomes from Nigeria (2021-2023) and traced the lineage back to its emergence around July 2014 from southern Nigeria, specifically Rivers State.
- The study also found that human-to-human transmission significantly increased the virus's evolutionary rate and emphasized the importance of better pathogen surveillance and response strategies.
Article Synopsis
- Nigeria and Cameroon reported their first mpox cases in over 30 years starting in 2017 and 2018, with Nigeria's outbreak recognized as a human epidemic.
- The study focused on understanding the zoonotic transmission dynamics of the mpox virus across the Nigeria-Cameroon border, revealing ongoing cases driven by a new Clade IIb.1 lineage and highlighting significant cross-border viral spread.
- The findings indicate that southern Nigeria is likely the origin of the mpox epidemic, with evidence of a zoonotic precursor lineage present in local animal populations for over 45 years, emphasizing the persistent risk of MPXV emergence in both countries.

Article Synopsis
- Identifying various animal hosts involved in spill-over events of infectious diseases is essential for understanding how viruses like Lassa virus (LASV) are transmitted to humans and pose public health risks.
- Researchers conducted a study in southern Nigeria, screening domestic and non-domestic animals, including birds and lizards, to assess their potential as LASV reservoirs.
- Results showed lizards had the highest positivity rates for LASV, while cattle showed significant seropositivity, pointing to the need for further analysis of these animal hosts to inform strategies for managing Lassa fever transmission.
