In.roduction. Motorcyclists bear a disproportion.te burden.of morbidity an. mortality from road acciden.s.

Methods: It was a cross-section.l study con.ucted usin. data from a cohort of motorcyclists in.olved in.acciden.s an. recruited in.five hospitals in.Ben.n.from July 2019 to Jan.ary 2020. The depen.en. variable was n.n.return.to work 12 mon.hs after the acciden. (yes vs n.). The in.epen.en. variables were categorized in.o two groups: baselin. an. 12-mon.h follow-up variables. Logistic regression.was used to determin. the factors associated with n.n.return.to work at 12 mon.hs amon. the participan.s. Results: Amon. the 362 participan.s, 55 (15.19%, 95% CI = 11.84 - 19.29) had n.t return.d to work 12 mon.hs after the acciden.. Risk factors for n.n.return.to work iden.ified were: smokin.

Backgroun.: The Marburg virus (MARV) is the causative agen. of Marburg virus disease (MVD). This filovirus first appeared in.1967 an. has sin.e caused several outbreaks with case fatality rates between.23% an. 90%. The earliest cases of MVD are thought to be caused by exposure to an.in.ected an.mal, either a reservoir host (some bat species, e.g., Rousettus aegyptiacus) or a spill-over host, such as n.n.human.primates. The virus is spread between.people by direct con.act with blood or other bodily fluids (in.ludin. saliva, sweat, faeces, urin., tears, an. breast milk) from in.ected in.ividuals. Despite the high fatality rate, the Marburg virus has n. vaccin. or drug treatmen.. Recen. outbreaks of the virus in.2023 in.Tan.an.a an. Equatorial Guin.a have reign.ted the n.ed to develop effective therapeutics, especially in.the wake of the COVID-19 pan.emic. Purpose: This review seeks to highlight the drug discovery efforts aimed at developin. vaccin.s or possible treatmen.s as poten.ial therapeutics. Several existin. an.iviral agen.s are bein. probed, an. vaccin.s are in.pre-clin.cal an. clin.cal stages. n.tural products are also an.importan. source of possible drugs or lead compoun.s an. when.coupled with computation.l techn.ques, these strategies offer possible therapeutics for the Marburg virus, especially in.Africa, which has a high disease burden. Methods: Usin. the search en.in.s Google Scholar an. PubMed;keywords e.g. Marburg virus, Marburg treatmen.s, Marburg virus drug discovery were utilized. Several results were yielded, an. articles published in.recen. years were accepted in.o the fin.l *** an. Con.lusion. This study shows there is a growin. in.erest in.therapeutics for the Marburg virus, especially with the recen. outbreaks an. pan.emic preparedn.ss. In.tiatives that to support vaccin. developmen. an. access like the MARVAC con.ort time are critical to fightin. this public health threat.
