Peru is suffering a very bad outbreak of something that’s been nicknamed “break-bone fever”—dengue. In fact, it’s been a historically bad outbreak, as in the worst dengue outbreak that the country has ever had. The outbreak has already left over 146,000 people infected and at least 248 dead. It’s also resulted in the resignation of Rosa Gutiérrez, MD, from her post as Peru’s Minister of Health amidst questions about her handling of the outbreak. And don’t expect Peru to get a break from this outbreak any time soon.
