Electronics giant Samsung is donating 3,000 smartphones to support the fight against Ebola in the virus' three worst-hit African countries: Guinea, Liberia and Sierra Leone.

GALAXY S3 Neo devices, worth about $1 million, will be used by the Humanitarian Connectivity Project, a United Nation's project that uses mobile devices to provide support in disaster areas.

60 Ebola medical clinics in the three countries will receive the devices, says Samsung.

"By installing the UN's Smart Health Pro mobile application, medical staff can utilise the smartphones to treat patients and collect medical data, while quarantined patients can contact their families using the devices," says Samsung in a statement.

"All donated smartphones will be destroyed once the virus outbreak has subsided," adds the company.

Ebola has had a devastating effect in West Africa where the death toll has hit over 4,000 people.

Cases of the virus have even been reported in the US and Europe.

The World Health Organisation (WHO) further says the outbreak could grow to 10,000 new cases per week.

Meanwhile, Samsung says it is also supporting other efforts to defeat Ebola in Africa, "including providing financial support for the purchase of hazmat suits in Ghana and distribution of hand sanitizers in the Democratic Republic of Congo, as well as launching an Ebola SMS text service in South Africa."
