A new Ebola outbreak is currently ongoing in the Democratic Republic of Congo, after the most severe outbreak in West Africa in 2014-2016 was controlled. Ebola outbreaks are usually a significant cause of death among pregnant women. The clinical presentation of Ebola Virus infection in pregnancy often mimics common pregnancy related bleeding complications or febrile conditions common in pregnancy. The large amount of body fluids discharged during the management of these conditions make pregnancy a highly risky intervention for nosocomial infection transmission, especially to health workers. In this review, we discuss the Ebola virus, its pathogenesis, clinical features, diagnosis and the current supportive intensive medical and obstetric- specific practices to ensure safe management of Ebola positive pregnant women. We present how Ebola may be managed in highly resourced settings where experience is limited in the management of pregnancy complicated by Ebola infection and how wherever these patients are managed, postpartum contraceptive support is necessary because of lingering concerns about sexual transmission. Wider issues highlighted by the Ebola outbreaks included the demonstration of how weak health systems from prolonged lack of investment, in the face of highly infectious diseases like Ebola Virus infection, can pose a risk to the global community, bringing sharply into focus the need for essential collaboration between national health departments and international health organizations such as the World Health Organization.

Many virus species, including Ebola virus, Marburg virus, SARS-CoV-2, dengue virus (DENV) and Zika virus (ZIKV), exploit CD209 and CD209L as alternative or attachment receptors for viral cis- or trans-infection. Thus, CD209 and CD209L may be critical targets for the development of therapeutic monoclonal blocking antibody drugs to disrupt the infection process caused by multiple viruses. Here, we produced a human chimeric monoclonal blocking antibody that simultaneously blocks CD209 and CD209L, namely 7-H7-B1.

Background: Ugandan health authorities declared an outbreak of Ebola disease (EBOD), caused by the Sudan virus, in September 2022. A rapid review was conducted to update the Public Health Agency of Canada's guidelines for infection prevention and control measures for EBOD in healthcare settings to prepare for potential introduction of cases.
Objective: Summarize the available evidence on personal protective equipment (PPE) use by healthcare workers (HCWs) to prevent exposure to and transmission of viral hemorrhagic fevers (VHFs), including Ebola virus.

Ebola virus (EBOV) causes severe disease in humans, with mortality as high as 90%. The small-molecule antiviral drug remdesivir (RDV) has demonstrated a survival benefit in EBOV-exposed rhesus macaques. Here, we characterize the efficacy of multiple intravenous RDV dosing regimens on survival of rhesus macaques 42 days after intramuscular EBOV exposure.

The Ebola virus (EBOV) causes severe disease in humans, and animal models are needed to evaluate the efficacy of vaccines and therapeutics. While non-human primate (NHP) and rodent EBOV infection models have been well characterized, there is a growing need for an intermediate model. Here, we provide the first report of a small-particle aerosol (AE) EBOV ferret model and disease progression compared with the intramuscular (IM) EBOV ferret model.

: Orthoebolaviruses and orthomarburgviruses are filoviruses that can cause viral hemorrhagic fever and significant morbidity and mortality in humans. The evaluation and deployment of vaccines to prevent and control Ebola and Marburg outbreaks must be informed by an understanding of the transmission and natural history of the causative infections, but little is known about the burden of asymptomatic infection or undiagnosed disease. This systematic review of the published literature examined the seroprevalence of antibodies to orthoebolaviruses and orthomarburgviruses in sub-Saharan Africa.
