CNN reports that a nurse who traveled on an air flight may have contaminated passengers on a plane exposing another 800 flyers to Ebola.
Children in a public school have been sent home due to suspected Ebola virus.
The incubation time for symptoms to occur from Ebola virus is 4-21 days.
These exposed subjects should theoretically be quarantined for that period of time. They have secondarily exposed others.
What will be found is that some subjects exhibit Ebola virus in blood samples.
Recent evidence suggests well-nourished individuals will simply develop antibodies and no symptoms or mild symptoms (transient fever) and fatigue. In one published study in Africa about 7 out of 10 exposed to Ebola developed antibodies without a vaccine.
Immune compromised individuals (smokers, drinkers, diabetics, others) may be at greater risk for developing full-blown life-threatening Ebola.
