April 25th is World Malaria Day

This is a reminder that Malaria is still a major killer for half of the world population. In 2015, there were 214 million new malaria cases, and roughly half a million people died of this mosquito-borne disease.

The San Francisco Bay area used to be a malaria infested area, and only after 1951, malaria was considered eliminated from the United States.
