Outbreak response in the Democratic Republic of the Congo
In a complex environment, partners of the polio programme are working to vaccinate every child.
In the Democratic Republic of the Congo, emergency response has been ongoing since 2017 to overcome outbreaks of circulating vaccine-derived poliovirus, caused by low rates of routine immunization. In the battle to close the outbreak, health workers, partners of the Global Polio Eradication Initiative, Governors of affected provinces, and the Ministry of Health are working together to vaccinate every child. In a context with weak health systems and other high-profile health and humanitarian emergencies, these united efforts are crucial to boost population health and keep all young children safe from paralysis.
In Tanganyika province, where poliovirus was first detected in September 2017, outbreak response is focused on reaching all vulnerable populations with the safe, effective oral polio vaccine. Health infrastructure is weak in the province, and it has taken concerted efforts to reach many children. Here, mothers with their babies queue for polio immunization activities in Manono district, organized with the support of WHO, UNICEF and partners.
Despite several campaigns, immunity gaps still remain. Continuing cases from several virus strains in the country show that the battle to protect every child from paralysis is far from over. Here, a nurse carefully places vaccines vials back in a cooler during immunization activities in Manono. It is critical that the polio vaccine is kept cool, a considerable challenge in warm locations far from the nearest vaccine storage facility.

The Democratic Republic of the Congo has some of the lowest vaccination rates worldwide, and it is hoped that the lessons learned in overcoming this and other health emergencies will help strengthen the country’s health system for the future, and prevent other outbreaks.
A community mobilizer tells a woman in a village in Manono about the polio vaccination campaign that has just begun. Community mobilizers, usually local people trained by UNICEF and partners, are a critical part of efforts to ensure that every child is protected from the virus. Going house to house, they speak to parents about the dangerous poliovirus, and answer questions about the vaccine. Often, they also provide other health service support, including child and maternal health advice.

Amongst the communities here, there are children whom the virus has already reached. Remy Muyombi was previously an opponent of vaccination. Since his three-year-old son Justin was affected by polio paralysis, he has become a strong advocate of the campaigns ongoing in his district. So far in 2018, there have been eleven confirmed cases of polio paralysis due to the outbreak. In 2017, 22 children were paralyzed.
A community health worker crosses a shallow stream with his bike to reach the most distant children in Manono health zone. Many communities here live hours from the nearest road, far from any route that a car could easily traverse.
After a household is visited with vaccines, health workers mark the home with chalk to show that the children there have been immunized. They also collect paper records of vaccination, to feed back into a central monitoring and evaluation system coordinated by WHO.
Community mobilizers speak to a mother in Kalunga site for internally displaced people in Tanganyika Province. Regular movement of people in the Democratic Republic of the Congo complicates outbreak response, as there is a real threat of virus spread. The programme works specifically with moving and displaced populations to boost immunization rates, and collaborates with other UN agencies to gather up-to-date information on population movements and the wider humanitarian situation in the country.

More polio immunization activities are planned for the coming months, building on commitment from the government of the Democratic Republic of the Congo and provincial governors. Working with other programmes, and in complex contexts, the polio eradication teams continue their work to keep every child safe from polio paralysis.
