My 62 year old cousin was bitten by a mosquito and developed encephalitis this April. She was dead three days later.
That's terrible.
The horses around here have trouble with EEE.
I am taking precautions, using mosquito repellent and sleeping inside a mosquito net, as I am over eighty years old. I was bittten a few weeks ago and had no ill effects so I know that not every mosquito carries the virus.
