Outbreak Preparation and Response

Community Response

Risk Communication and Community Engagement teams on the ground have been working closely with Infection Prevention and Control teams this week in support of the Safe Injection Campaign, an initiative aimed at encouraging the safer use of needles and injections in homes as a means of reducing EVD transmission risks. The campaign will commence on 5 May 2019, alongside activities for the World Hand Hygiene Day.

As part of the continued efforts to empower communities to be more actively engaged in the EVD response, requests received from the numerous dialogues with local residents are being reviewed to aid the transfer of the response ownership back to the community. Further plans are currently being drafted on who will deliver these feedback to the communities in a timely manner. Lastly, Risk Communication and Community Engagement teams are also working closely with other WHO partners to bring about a new mass communications campaign to comprehensively promote key messages to the affected communities from all outbreak response pillars. See more here.

The Paul G Allen Family Foundation named the WHO, Red Cross, and UNICEF as recipients of the Ebola Response Accelerator Challenge, funding projects that aim to end this outbreak quickly. The Red Cross project will track community data for response workers, while the WHO’s project aims to train Congolese medical students and youth leaders about Ebola. The grant allows UNICEF to establish a new text message system.

Vaccination

As of 2 May 2019 – since vaccination began on 8 Aug 2018, 109 844 people have been vaccinated [total numbers of people vaccinated in North Kivu, Ituri, Tshopo, and Haut-Uele provinces can be seen here. Preliminary data from the World Health Organization (WHO) released last month show the vaccine is 97.55% effective against the virus – see here. An article in Axios also explored the preliminary findings looking at the effectiveness of the vaccination programme currently in place within the DRC.

Preparedness in neighbouring countries

Uganda has also increased its ebola preparedness efforts, recently completing an Ebola simulation exercise. In addition, the International Rescue Committee (IRC), in collaboration with the Ministry of Health and Kagadi district, is to establish Ebola screening points at points of entry into the country on the shores of Lake Albert. The Infectious Diseases Institute (IDI), as an implementing partner in the district, has been providing vehicles to enable the district Ebola task force go to hard-to-reach areas down the escarpment.

Disease Research

A new paper in PNAS assesses the effectiveness of the vaccination programme that was implemented in the May-July 2018 Ebola outbreak in the Democratic Republic of Congo.

Using a spatial model that incorporates human mobility, poverty, and population density, the researchers assessed the effectiveness of the vaccination program that was implemented during the 2018 Ebola outbreak. Their results demonstrate that even modest delays in initiating vaccination would have markedly eroded the impact of the program. The methodology used has applicability for identifying areas at risk during outbreaks of other emerging and reemerging diseases.
