Filovirus outbreaks in Africa (2021-2025) showed high case fatality ratios (CFRs). Despite official termination, epidemics persisted due to high pathogenicity and transmissibility, necessitating expanded global collaboration for pandemic preparedness.
Area of Science:
- Virology
- Epidemiology
- Public Health
Background:
- Multiple Filovirus outbreaks occurred in Africa between 2021 and 2025.
- These outbreaks exhibited high case fatality ratios (CFRs), consistent with Filovirus pathogenicity.
Discussion:
- Epidemics continued despite official outbreak termination due to the viruses' inherent transmissibility and pathogenicity.
- This highlights the challenges in controlling Filovirus spread and the need for sustained vigilance.
Key Insights:
- Filovirus outbreaks pose a persistent threat, with epidemics continuing post-termination.
- Elevated CFRs underscore the severity and public health impact of these viral hemorrhagic fevers.
Outlook:
- Continued and expanded collaborative global strategies are crucial for mitigating future Filovirus outbreaks.
- Enhanced pandemic preparedness is essential to effectively manage and control persistent viral epidemics.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
