Ebola crisis: 'Many exposed' to infected Mali girl

The authorities in Mali have confirmed the death of the country's first Ebola patient, a two-year-old girl.

The World Health Organisation said the toddler had travelled hundreds of kilometres by bus from Guinea through Mali showing symptoms of the disease.

More than 40 people known to have come into contact with her have been quarantined.

The girl was being treated in the western town of Kayes, after arriving at a hospital on Wednesday.

The child had travelled more than 1,000 km (600 miles) from Guinea through the capital, Bamako, to Kayes.

"The child's symptomatic state during the bus journey is especially concerning, as it presented multiple opportunities for exposures, including high-risk exposures, involving many people," the WHO said.

The girl's mother died in Guinea a few weeks ago and the child was then brought by relatives to Mali.

Guinea, Liberia and Sierra Leone have seen most of the 4,800 Ebola deaths.

In the US, the governors of the states of New York and New Jersey have ordered a mandatory 21-day quarantine period for all doctors and other travellers who have had contact with Ebola victims in West Africa.

Anyone arriving from affected West African countries without having had confirmed contact with Ebola victims will be subject to monitoring by public health officials.

The moves go beyond anything so far announced at a national level by the Obama administration and come after a doctor, Craig Spencer, was diagnosed with Ebola following his return to New York from Guinea.

People in the city have expressed concern that Dr Spencer used public transport and restaurants before being diagnosed.
