|---|---|
| Route of infection | When the body fluids (blood, secretions, vomit / excretion) of a patient with symptoms are touched without sufficient protection, the virus enters through wounds and mucous membranes and is transmitted. It is also transmitted from wild animals in endemic areas. In general, it is not transmitted from asymptomatic patients and there is no airborne infection. |
