hypodemic

n. A disease whose fully reproductive rate (R) is less than 1; a disease with an average probability of infecting less than one susceptible new host; a disease that is on the decline.
(not to be confused with hypodermic)

When R is greater than 1, the infection is growing exponentially, and it's at that point that it's known as an epidemic. When it holds steady around 1, that's when a disease is called endemic. And less than one means that it's on the decline. Hypodemic?

Trying to do parkour, I jumped down to a bar and hung from it. I caught the bar, but I landed too hard and bruised my webby cranny.
