Originally published by Citizen Digital — Read the original article →
Contact tracing is one of the key measures used to contain Ebola outbreaks, allowing health authorities to identify and monitor people who may have been exposed to the virus before they develop symptoms.
The incubation period for Ebola virus disease (EVD), which is the time between infection and the onset of symptoms, ranges from two to 21 days.
Symptoms commonly begin several days after exposure, although the exact timing varies from person to person.
