The organization has warned that small flare-ups of the disease are likely because the virus can persist in the bodily fluids of survivors. Officials estimate that the virus can be present in semen for up to a year after survivors have recovered from the disease and show no symptoms.
Ten flare-ups have been reported in the past nine months in the three countries that were hardest hit by the outbreak: Guinea, Liberia and Sierra Leone.
The risk of transmission from survivors is low but significant, officials have said, noting that the risk decreases as victims’ immune systems clear out the virus. that started two years ago killed more than 11,300 people and infected more than 28,500.
