With public health officials declaring emergencies related to the current measles outbreak, I thought I would share some data visualizations related to the impact of vaccines on infectious diseases.

These heat maps were originally published in The Wall Street Journal in February 2015 in an article by Tynan DeBold and Dov Friedman. A link to the related article is provided above.

These heat maps show that the number of infected people, measured over 70-some years and across all 50 states and the District of Columbia, generally declined after vaccines were introduced.

The heat maps below show number of cases per 100,000 people.
