Wealthy nations need to do more to fix health systems and help in the recovery process for Sierra Leone, Guinea, and Liberia, the three countries hit hardest by the Ebola outbreak, international development agency Oxfam said on Tuesday.

All three countries were showing strong economic growth before the sudden outbreak of the deadly virus that gripped the world in fear, and now that growth has vanished ever since the first cases of Ebola emerged in Guinea last March, according to an Associated Press report.

Ebola appears to be subsiding in those nations, but Oxfam argued that there needs to be a plan to assist those nations, which are dealing with cash shortages and a lack of access to basic necessities like sanitation and education.

Oxfam GB Cief Executive Mark Goldring said the international community’s slow response to the early stages of the Ebola outbreak has resulted in families in those countries going “through hell,” according to the report. He said that the world cannot wipe its hands of the issue now that the disease rates are dropping, and that wealthy nations need to lend a hand in order to avoid a “double-disaster.”

About 73 percent of families in three counties in Liberia, for example, have lost an average of 39 percent of their income. This, combined with rising food prices, has meant that 60 percent of people have been starving for the last seven days, according to Oxfam.

A total of 8,600 people have died in the three nations from the disease, according to the World Health Organization. WHO member nations approved a resolution that allow the United Nations to better respond to emergencies such as this one, as a slow response may have resulted in the deaths of thousands.

Failure to continue to be vigilant in fighting Ebola now that cases are subsiding could result in a resurgence of the disease, according to Doctors Without Borders.
