In Twitter posts today, Peter Salama, MD, the WHO’s deputy director-general of emergency response, said sadly, many health workers in Mangina were exposed to Ebola early in the outbreak. And since health worker infections are known to amplify Ebola outbreaks, health officials expect the current DRC outbreak to get worse before it gets better. “Given complexities, we ask all partners to support government-led response with their most experienced staff,” he said. Salama said the event is on an “epidemiological precipice” and that there’s a crucial time-limited window of opportunity to prevent the Ebola outbreak from taking hold in areas that are much more difficult to access due to security concerns. “There is not a minute to lose,” he said.
