Resolve to Save Lives partnered with primary health facilities in Sierra Leone to train frontline health workers to better detect and report infectious disease cases in our Epidemic-Ready Primary Health Care initiative. In one outstanding example of the initiative’s success, four health facilities recently brought a local outbreak of measles to an end with no recorded deaths, and met 7-1-7 timeliness targets to detect and report all confirmed cases. Thanks to targeted training and mentorship, frontline workers are overcoming one of the biggest barriers to stopping infectious disease outbreaks quickly—preventing epidemics and saving lives.
