A substantial amount of epidemiological data has been reported on Enterovirus D68 (EV-D68) infections after the 2014 outbreak. Our goal was to map the case fatality rate (CFR) and prevalence of current and past EV-D68 infections. We conducted a systematic review (PROSPERO, CRD42021229255) with published articles on EV-68 infections in PubMed, Embase, Web of Science and Global Index Medicus up to January 2021.

- Hepatitis B virus (HBV) is a major global health issue, impacting around 2 billion people and causing about 1 million deaths annually, with healthcare workers (HCWs) at high risk due to potential exposure to infected blood.
- This study aims to assess the global prevalence of HBV serological markers among HCWs by analyzing relevant research published between 1970 and 2019, including a total of 227 studies from 71 countries.
- The meta-analysis revealed a pooled prevalence of current HBV infection (2.3%), with very low rates for HBeAg (0.2%) among the HCW population, highlighting the importance of monitoring and improving HBV control strategies in healthcare settings.
Rabies is transmitted to humans mainly by dogs but also by other animal species. Reliable data on the incidence of Rabies virus (RABV) in humans, dogs, and other animal species in Africa, could be essential in the implementation of a global strategic plan to eliminate the RABV by 2030 as adopted by the WHO, OIE, and FAO. We searched the Pubmed, Embase, Scopus, African Journal Online, and African Index Medicus databases for relevant studies that report data on the incidence of RABV in Africa up to February 17, 2020.

There are uncertainties about the global epidemiological data of infections due to Crimean-Congo hemorrhagic fever virus (CCHFV). We estimated the global case fatality rate (CFR) of CCHFV infections and the prevalence of CCHFV in humans, ticks and other animal species. We also explored the socio-demographic and clinical factors that influence these parameters.

- The researchers analyzed data from various databases spanning from 1969 to 2020, ultimately reviewing 109 reports which contributed to 291 prevalence records across 25 countries.
- The overall CFR for humans was found to be 29.7%, with a pooled prevalence of 8.7% in humans, 3.2% in rodents, and 0.7% in other mammals, indicating significant regional disparities and higher risks in Western Africa.
