  • The WHO has reported that 2017 saw outbreaks of measles worldwide. This includes an estimated 110,000 deaths, mostly among children under the age of 5.





  • More than 41,000 people were infected with measles in the first six months of 2018 in Europe, compared to almost 24,000 cases last year and 5,273 in 2016. (WHO). Measles has killed 37 people this year, and this is the highest number infected in the region in a decade.
  • Dr Mary Ramsay, head of immunisation at Public Health England, said: “The measles outbreaks we are currently seeing in England are linked to ongoing large outbreaks in Europe. The majority of cases we are seeing are in teenagers and young adults who missed out on their MMR vaccine when they were children.”

  • In June 2017, the UN announced Yemen was facing the “worst cholera outbreak in the world.” From September 28, 2016 to March 12, 2018 there were roughly 1.1 million suspected cholera cases and 2,400 associated deaths (UN Dispatches). In comparison, during a 2011 cholera outbreak prior to the country’s civil war, there were almost 32,000 cases and 134 deaths from cholera and Acute watery diarrhoea (Unicef).
  • In May 2018 it was reported that the weekly number of cholera cases was decreasing nationally. A cholera vaccination campaign began in May, after a one-year delay due to senior Houthi officials objecting to vaccinations.
