Measles

Measles, or rubeola, is a viral infection that starts in the respiratory system. It still remains a significant cause of death worldwide, despite the availability of a safe, effective vaccine. There were about 110,000 global deaths related to measles in 2017, most of them in children under the age of 5, according to the World Health Organization (WHO). Measles cases have also been increasing in the United States in recent years.
