Angola says the outbreak of the deadly Marburg virus, which has already killed 244 people, appears to be under control.
Health ministry officials in Luanda Friday said the virus, which has already stricken 266 people, has largely been confined to the northwestern province of Uige.
A spokesman said four neighboring provinces, including the capital where doctors previously detected infections, have not reported any new cases.
International aid groups, including the World Health Organization, are working to control the highly contagious and incurable virus.
Experts say the Ebola-like virus, which is spread through contact with bodily fluids, can be contained with relatively simple hygienic precautions.
Previously, the most serious outbreak of the disease occurred in the neighboring Democratic Republic of Congo, killing at least 123 between 1998 and 2000.
