TAIPEI -- The Centers for Disease Control (CDC) heightened a health advisory on travel to Nigeria Wednesday from "watch" to "alert" due to cases of the deadly Ebola virus reported there.
There have been four Ebola cases confirmed in the country so far, including one death, following the escalating outbreak that has spread to several countries in West Africa, the CDC said.
The CDC already raised its travel advisory Aug. 1 for Guinea, Liberia and Sierra Leone from "alert" to "warning" — the highest level — amid the more severe Ebola situation there.
According to the World Health Organization (WHO), as of Aug. 1, the cumulative number of Ebola cases in Guinea, Liberia, Sierra Leone and Nigeria stood at 1,603, with 887 deaths.
Under Taiwan's travel advisory system, a Level-1 "watch" advisory urges those who are bound for listed destinations to exercise vigilance and take health precautions, while a Level-2 "alert" calls for would-be travelers to maintain a high degree of caution and take strengthened protective measures, especially when they visit certain high-risk places. A Level-3 "warning" advises against travel to listed destinations.
The most recent outbreak of Ebola, the worst on record according to the WHO, is occurring primarily in remote villages in central and western Africa, near tropical rainforests.
The Ebola virus can cause severe viral hemorrhagic fever in humans and has a fatality rate of up to 90 percent, the WHO said.
No licensed treatment or vaccine is available for people or animals.
