In 2005, Libya conducted a national campaign to vaccinate all people between nine months and 20 years old. Libya’s biggest measles outbreak in recent history occurred in 2009 when the country had 329 confirmed cases. For comparison, the year before that, there were only eight. Libya seemed to have everything under control by 2014, when the numbers started to steadily decline — until this year.

22. Benin
> Population: 11.4 million
> Cases in 2018: 498
> Cases in 2017: 192
> Cases in 2016: 98

This country in West Africa has dealt with worse measles outbreaks in the recent past. In 2013 and 2014, there were 757 and 761 measles cases, respectively, and almost 1,000 in 2009. In fact, only twice over the last decade did the number of cases fall under 100. After a 2009 WHO/UNICEF vaccination campaign that covered more than 72% of the population, the number of measles cases decreased by nearly two-thirds.

Burkina Faso is dealing with the worst measles outbreak since at least 2006. This is the first year in over a decade when the number of confirmed cases has exceeded 1,000. It fell by almost half between 2012 and 2013, from 803 to 422. The CDC has worked on improving the country’s public health system by introducing vaccines.
