Fruit bats (FB)?
Highest occurrence is in the region of FBs. 8/20 FB species carry ebola
FB movement/breeding?
travel far for food and better living conditions. breed in dry season (December to May) longest region increases potential to replicate EVD
Climate?
High humidity/rainfall = increase of contact between people, decrease in assess to healthcare/infection control
Location of EVD?
within 10 degrees of equator, warm equatorial regions, high annual precipitation, rainforest
Rural/remote areas ?
limited healthcare higher risk of coming into contact with infected fauna
Human migration in West Africa is …
7 times higher then that of the global average
How does climate influence the timing of Ebola outbreaks?
Ebola outbreaks often occur during periods of high humidity and heavy rain, which increase human contact and reduce access to healthcare.
Why does Ebola thrive in areas with high rainfall and stable temperatures?
These conditions help the Ebola virus survive in the environment, supporting its natural reservoirs and increasing transmission risks.
What role do fruit bats play in the spread of Ebola?
Fruit bats are natural reservoirs of the Ebola virus and help spread it, especially during their breeding and migration seasons.
How many species of fruit bats are known to carry Ebola?
8 out of 20 known fruit bat species carry the Ebola virus.
When do fruit bats usually breed, and why is it significant?
Fruit bats breed during the dry season from December to May, when they gather in large colonies, increasing the chances of virus transmission among them.
What is the connection between fruit bat migration and Ebola outbreaks?
Fruit bats migrate in large numbers, often aligning with the timing and location of Ebola outbreaks due to increased virus spread during breeding.
How has deforestation contributed to the rise in Ebola outbreaks?
Deforestation pushes humans closer to wildlife that carry Ebola, increasing the risk of disease transmission.
How much forest area has been lost in the Congo over the past two decades?
Forest areas in the Congo have decreased by 83% due to expanding agricultural activities.
What percentage of West Africa’s economy and workforce is tied to agriculture?
Agriculture accounts for about 35% of the economy and employs around 60% of workers in West Africa.
How does land cover change increase the risk of Ebola outbreaks?
It creates environments where disease-carrying animals thrive and brings people into closer contact with them.
Why is human migration so common in West Africa?
Migration is driven by long-term conflict, poverty, and the search for better living conditions and economic opportunities.
How does migration impact the spread of Ebola?
High levels of movement spread the virus over wider areas, including from rural villages to crowded urban centers.
What happened during the 2014 Ebola outbreak in Liberia?
Liberia had the second-highest number of Ebola cases and the highest rate of internal displacement, allowing the virus to spread quickly in urban areas.
