The worst Ebola outbreak on record is now projected to infect up to 1.4 million by January 2015, according to scientists and studying the deadly virus.
Studies by the US Centers for Disease Control and Prevention have calculated that the outbreak could infect as many as 20,000 people in West Africa by November, with this figure increasing up to 1.4 million by early next year without international efforts to contain its spread.
The projected figure for those infected by January 2015 includes cases 'under-reported' or not logged by medics in West Africa, given the remote rural locations of many victims.
