"According to the Department of Health, about 1 in 15 people infected with measles gets pneumonia, and 1 in 1,000 develops brain swelling, which can lead to brain damage or death.It's also possible for a person, many years after a measles infection, to develop a devastating and disabling brain disorder known as subacute sclerosing panencephalitis, which is fatal. In 2017, there were 110,000 measles deaths globally, mostly among children under the age of five." from this article
