On 6 February, the WHO declared that Uganda was Ebola-free, with no new cases in the previous 21 days. 173 people had died. While the survivability rate in previous Ebola outbreaks was as low as 10%, the Ugandan outbreak had a survivability of nearly 50%, an increase partially attributable to better health care. Lukwiya was the last health worker at St. Mary's to die from Ebola. Foreign epidemiologists credit Lukwiya with accelerating the government's public education campaign to stop the spread of the disease with his phone call to Kampala on 8 October. The number of lives possibly saved by this quick action is variously numbered in the hundreds to the thousands.
