The Egyptian Health and Population Ministry has issued an order that anyone coming from Equatorial Guinea must be quarantined before allowed to enter the country following an outbreak of the Marburg virus.

Nine people died have died in the latest outbreak in eastern Equatorial Guinea, Central Africa, where authorities imposed a quarantine in one of the provinces to contain the epidemic.

The ministry said that the incubation period for the disease ranges between two and 21 days, and that the virus is transmitted through contact with the patient’s blood or other body fluids that contain the virus.
