Ebola spreads through direct contact with bodily fluids (such as blood, saliva, urine) of infected individuals or animals. It can also be transmitted indirectly through contaminated objects like needles or surfaces. Close contact with infected patients during caregiving without proper protective measures increases the risk of transmission. Additionally, traditional burial practices involving close contact with deceased bodies contribute to further spread. Understanding these modes of transmission helps healthcare professionals design effective strategies for containment and prevention efforts.
2.1 Virology of the Ebola Virus
The Ebola virus, named after the Ebola River in Congo, where it was first identified in 1976, belongs to the family Filoviridae. It is a single-stranded RNA virus with a filamentous shape that can measure up to 14,000 nanometers in length. This deadly pathogen is classified into five distinct species: Zaire ebolavirus (EBOV), Sudan ebolavirus (SUDV), Bundibugyo ebolavirus (BDBV), Reston ebolavirus (RESTV), and Tai Forest ebolavirus (TAFV).
Among these species, EBOV is responsible for most outbreaks and has the highest fatality rate of about 50-90%. The Ebola virus primarily targets cells of the immune system such as macrophages and dendritic cells. Once inside a host’s body, it binds to specific receptors on these cells and enters them through endocytosis.
Once inside the cell, viral replication occurs rapidly, leading to massive destruction of infected cells. This triggers an intense inflammatory response by the immune system which further contributes to tissue damage.
Understanding the virology of the Ebola virus provides crucial insights into how this highly infectious pathogen invades and replicates within its host. Such knowledge aids in developing effective strategies for prevention and control measures against future outbreaks.
