Molecular mechanisms of Ebola pathogenesis

Area of Science:

• Virology
• Infectious Diseases
• Public Health

Background:

• Ebola viruses (EBOVs) and Marburg viruses (MARVs) are highly lethal viruses, causing significant global health crises.
• The 2014-2016 West Africa Ebola Virus Disease (EVD) epidemic was the largest and longest on record, underscoring the need for robust surveillance and response.
• Recent EVD cases in Guinea highlight the ongoing threat, necessitating extended surveillance periods to detect potential outbreaks from missed chains, animal reservoirs, or persistent infections in survivors.

Purpose of the Study:

• To review current knowledge of EBOV pathogenesis.
• To describe vaccine and therapeutic candidates for EVD currently in clinical trials.
• To discuss viral persistence mechanisms and long-term health consequences for EVD survivors.

Main Methods:

• Literature review of EBOV pathogenesis.
• Analysis of clinical trial data for EVD vaccines and therapeutics.
• Examination of studies on viral persistence and sequelae in EVD survivors.

Main Results:

• EVD pathogenesis involves complex interactions between the virus and host immune system.
• Several promising vaccine and therapeutic candidates are in various stages of clinical development.
• Viral persistence in survivors and long-term health issues are significant concerns requiring further investigation.

Conclusions:

• Continued vigilance and enhanced surveillance are crucial for controlling EVD outbreaks.
• Development of effective vaccines and therapeutics is vital for combating EBOV and MARV infections.
• Addressing the long-term health sequelae in EVD survivors is essential for comprehensive patient care and public health.
