Measles Outbreak in South Sudan
A very large outbreak of measles is being reported in South Sudan. According to Medecins Sans Frontieres (MSF), 460 cases have been recorded with 7 deaths in children under 5 years. Most cases come from the counties of Yambio and Nzara counties in Western Equatoria.
MSF is urging authorities to launch a vaccination program as soon as possible. More than 90% of the affected children have not been vaccinated.
Measles is a very infectious disease requiring high rates of vaccination to reduce or eliminate transmission. There are many factors, including the pandemic, which have impacted on the low rates of vaccine coverage.
Travellers to South Sudan should be aware of the risk of exposure and seek advice if travelling with young children. Children normally receive their first dose of the MMR vaccine at 12 months of age, but this should be brought forward if travelling to areas of risk. Mortality rates are higher in young children. Treatment can only be supportive and access to health services will be limited.
The risk of exposure to measles has increased globally since the pandemic. Unvaccinated or inadequately vaccinated individuals will not be protected by the “herd” when overseas.
The current outbreak comes at the same time health authorities have been trying to control an outbreak of Yellow Fever in South Sudan.
