“The death of Dr Mouzoko also underscores that when health workers are targeted and attacked, it has huge ripple effects that are felt by the people they served, the communities in need, and of course their loved ones, friends and co-workers. It’s a loss for everyone, everywhere” – Dr Tedros said on Twitter.

The outbreak in DR Congo is the second largest and second deadliest Ebola outbreak the world has ever experienced and it is DR Congo’s ninth outbreak since 1976 when the disease was first discovered there. In its latest update on the outbreak, the WHO said: “As of 16 April, a total of 1290 confirmed and probable Ebola viral disease cases have been reported, of which 833 died (case fatality rate 65%).”

This is not the first time health workers have been attacked in the volatile northeast of DR Congo, near its borders with Rwanda and Uganda and where for years the government has been unsuccessful at countering rebel activities.

In February, two separate attacks on Ebola treatment centers forced the medical charity, Doctors Without Borders to evacuate staff and suspended medical services in the epicenter of the outbreak, Butembo and Katwa.

In March, an attack on another treatment center killed a police officer and injured others. Shortly after the attack that killed Dr Mouzoko, there was another attack on a treatment facility in which one assailant was killed and four others were captured.

Violent attacks in North Kivu province, is disrupting outreach efforts by medical teams to treat confirmed and probable cases of Ebola and affecting their ability to reach individuals at risk of the disease by virtue of coming into contact with an infected person.

Mass vaccination has helped to prevent more infections and death according to a preliminary report [pdf] on the efficacy of the trial vaccine released earlier this month. Of the 93,965 at-risk people who consented to vaccination, 71 cases were confirmed and nine deaths occured. There have been no deaths recorded in vaccinated people who showed symptoms more than 10 days after the trial vaccine was administered.
