Efforts have been made at national level, but more resources must be quickly committed and targeted to areas that are still suffering from this disease in order to stop this outbreak.
Measles is a highly contagious disease that is transmitted by air. Currently, in DRC, a measles patient infects on average two to three other people. There is no specific treatment once someone contracts measles, but a well-conducted vaccination campaign is extremely effective to prevent new cases. In areas with low immunisation coverage, vaccination can reduce infant mortality by 50 per cent.
Barriers prevent stopping the outbreak in its tracks
Several factors are contributing to the spread of the current epidemic in DRC. There is extremely low immunisation coverage in some regions of the country due to the lack of vaccines, vaccinators, or access to health structures.
On top of this, there are stockouts of the measles vaccine in the country, difficulties in keeping the vaccine at the right temperature until injection (which reduces its effectiveness), and logistical difficulties in getting the vaccines to their final destinations. The needs are enormous, and the national vaccination programme cannot keep up. In 2019, measles spread to all 26 provinces of the country.
The epidemic is showing no signs of abating: 9,605 new cases were reported in the last week of November, the highest number since the start of the year. The fatality rate this year, over two per cent, is twice as high as in previous years. Nearly three-quarters (73%) of deaths are children under the age of five.
Areas seeing more measles cases than first thought
In addition, measles cases remain underreported across the country. We have set up surveillance strategies to identify new areas affected by the epidemic, in order to start interventions as soon as possible. For example, in Viadana, in the province of Bas-Uélé, a small team went to assess the situation following a rapid increase in the number of cases notified in early December.
When an epidemic is declared, medical care and vaccination must be combined to stop the spread of the disease.

What they found there far exceeded the data they had received. In a single school of about 300 children, more than 100 students were ill with measles. This assessment enabled us to immediately start medical activities for these children and organise a vaccination campaign.
A similar system has been set up in the four provinces of ex-Katanga, in the southeast of the country, where MSF has created “sentinel” sites. In October 2019 MSF put in place a decentralised laboratory in order to quickly analyse suspected cases of measles and rubella. Prior to that, the samples would have had to be sent all the way to Kinshasa for analysis, which took several months.
“When an epidemic is declared, medical care and vaccination must be combined to stop the spread of the disease,” said Alex Wade, MSF head of mission in DRC. “Since mid-November, the Congolese health authorities started measles supplementary immunization activities in the whole country.”
“Meanwhile we continue to provide free quality medical care to patients,” said Wade. “But for now, the epidemic is still several steps ahead of the medical-humanitarian response.”
MSF providing care beyond measles
We are also active in the province of Kongo Central. To support the Congolese health authorities, on 13 December we opened a treatment centre for complicated measles cases in the general hospital in Matadi, capital of the province and the country's main port.
A week earlier, another team had opened a similar facility a few hours’ drive west, in the coastal town of Muanda. These treatment centres were overloaded within a few days after their opening, and teams had to relocate to larger structures.
But they also support the treatment of measles in the surroundings of these health zones, by distributing treatment kits and strengthening surveillance and detection of new cases. They also provide free transport for patients who need to be transferred to clinics and hospitals.
Since 2018, MSF teams have been working to provide measles patients with appropriate care and undertake vaccination in various provinces of the country including Ituri, Haut and Bas-Uélé, Tshopo, Kasai, Mai-Ndombe, Kwilu, and Sud Ubangi.
Between January 2018 and October 2019, a total of 46,870 patients were treated, and 1,461,550 children vaccinated by our teams in 54 health zones.
Mass vaccination in bid to prevent further spread
In collaboration with the Congolese Ministry of Health, we also helped to strengthen measles vaccination activities in areas where the Ebola outbreak continues to spread and, as a result, where vaccination coverage for other diseases has dropped dramatically.
Unfortunately, many regions are still not vaccinated.
“Supplementary immunisation activities have been launched by the Congolese Ministry of Health, but there are still many health zones where the outbreak continues,” says Wade. “We must wait until the end of these vaccinations to have a better understanding of the evolution of the epidemic.”
“However, the current implementation of this campaign suggests that needs will persist, especially for children over the age of five who will not have been vaccinated during this period,” Wade continues. “It will then be essential that humanitarian organisations and other responders pool all possible efforts to help the Congolese Ministry of Public Health to overcome this measles outbreak. Too many children have died from this easily preventable disease.”
MSF has been working in the Democratic Republic of Congo since 1981. Our teams respond to the needs of communities during health and humanitarian emergencies (epidemics, pandemics, displacement of people, natural disasters, etc.) with the primary objective of reducing morbidity and mortality.
