3 Ebola Flashcards
what family does Ebola belong to
Filoviridae
how many species does Ebola contain
five species
example of non pathogenic ebolavirus
reston
example of highly pathogenic ebolavirus
Zaire
ebola virus reservoir and spread - enzootic
circulates bat population species – doesn’t cause disease in these species
epizootic
bat virus past to other animals
predominant epidemic feature
human to human transmission is predominant feature of epidemics
Ebolavirus pathogenesis
Release too many cytokines in infected cell
Endothelial cells fit together – tight junction but cytokine makes it leaky, fluid runs out of blood into tissues to lungs (drown in own blood fluid)
incubation period for ebola
2-21 days
when do ebola symptoms show
3-10 days after exposure
what are the early stages of ebola
fever over 101.5oF
headache
diarrhoea
what are the late stages of ebola
confusion
chest pain
vomiting
during recovery what happens in post infection
anemia
visual complications
how long is there a risk of ebola transmission for
up to 3 months in tears and semen
who is most likely to die with ebola
Those with lots of virus in their circulatory system more likely to die
