To prevent the spread of Ebola virus disease (EVD) from an imported case, case detection mechanisms must be highly sensitive, so as to detect the slightest suspicion that an individual may be infected. This must be reported to the public health authorities and, in turn, to the international community through the channels established by the International Health Regulations (IHR).
The identification of an Ebola virus case must take into account:
- clinical manifestations (even if these are initial, nonspecific manifestations)
- travel history (to areas where there is transmission)
- exposure history reported by the patient or obtained through epidemiological research.
Any patient with this combination of factors should be isolated immediately.
