Bamako - More than 90 people including UN peacekeepers were quarantined across Mali's capital on Wednesday after a 25-year-old nurse died of Ebola having treated a Guinea man who succumbed with Ebola-like symptoms that were not recognised.
The man, a Muslim imam from the border town of Kouremale, was never tested for Ebola. In a series of rites that may have exposed many mourners to the deadly virus, his highly contagious body was washed in a Bamako mosque and returned to Guinea for burial without precautions against Ebola.
The World Health Organisation said there were now four confirmed and probable Ebola deaths in Mali, adding that one was a friend who had visited the imam in hospital. The group did not give immediate details of the fourth case.
A doctor at the Pasteur Clinic where the nurse worked - one of Bamako's top medical centres and the default clinic for expatriates - is also suspected to have contracted Ebola and is being monitored.
About 20 UN peacekeepers who were at the clinic for injuries sustained while serving in the turbulent north of Mali were quarantined as a precaution, the UN mission said, without specifying their nationalities.
Mali, the sixth West African nation to record Ebola during the world's worst ever outbreak of the disease, must now trace a new batch of contacts just as an initial group of people linked to its first and only other case - a two-year-old girl who died last month - completed their 21-day quarantine on Tuesday.
Lack of training
The locations quarantined in Bamako, a mining and humanitarian hub with a population of nearly 2 million, include the clinic, the mosque where the imam's body was washed and the houses where the nurse lived and the imam stayed.
Concern is growing at the time it took between the imam dying and the steps needed to contain the deadly disease being put in place. Dr. Samba Sow, head of Mali's Ebola response, said the imam died on 27 Oct, two days after going to the clinic.
"This case shows the lack of training of doctors in Bamako. This training should have been done six months ago," one aid worker told Reuters, asking not to be named.
The government said on Wednesday that the nurse was confirmed with Ebola on Tuesday and died later that evening. All necessary steps to identify people who had come into contact with the nurse had been taken, it said.
Ousmane Doumbia, secretary general of the health ministry, said more than 90 people had been quarantined. The clinic was locked down by police on Tuesday night.
Mali shares an 800 km border with Guinea, which alongside Liberia and Sierra Leone has been worst affected by an Ebola outbreak that has killed 5 147 people this year.
The two-year-old girl had also brought Ebola to Mali from Guinea but Malian authorities said the border would remain open for now.
In a rare piece of good news, the WHO said on Wednesday that there were signs that the incidence of new cases was declining in Guinea and Liberia, although it reported steep increases in Sierra Leone.
