New York doctor tests positive for Ebola. Meanwhile in Liberia...

A New York doctor who treated Ebola patients in Guinea while working for Medecins Sans Frontieres has tested positive for the disease.

Dr Craig Spencer, 33, left Guinea on 14 October and came back to New York on 17. He developed a fever on Thursday 23 and immmediately contacted medical services. He is now being kept in isolation at New York's Bellevue Hospital.

New York's mayor Bill de Blasio said in a press conference that there was no reason for New Yorkers to be "alarmed": "Ebola is an extremely hard disease to contract. New Yorkers who have not been exposed to an infected person's bodily fluids are not at risk."

That, obviously, didn't stop this happening:

Meanwhile in Liberia, as the Independent's Charlie Cooper reports this morning, disease experts have said international commitments to combat the disease are “grossly inadequate”.

Official figures from the World Health Organisation (WHO) show that there have been nearly 10,000 cases and 4,868 deaths from Ebola so far, but difficulties in reporting mean that the figures are underestimated.

In the first study to apply mathematical models of disease spread to the unprecedented outbreak, experts from Yale University and Liberia’s health ministry predicted that, in the worst-case scenario, there could be 113,000 cases and 67,000 deaths in the Monrovia area by 15 December.
