Leah’s Story

When Leah was just 4 years old, she was bitten by a mosquito carrying La Crosse virus. Two days after complaining of a headache that would not go away, Leah’s family took her to the emergency room. Leah died in her parents’ arms three days later from La Crosse encephalitis.

Prevention
