Rattlesnakes are coming out of hibernation, so it's time for Arizona desert dwellers to be particularly vigilant to avoid being bitten.

The Banner Good Samaritan Poison & Drug Information Center in Phoenix reports having seven snake-bite patients from Maricopa County in the past week.

Meanwhile, the Arizona Poison and Drug Information Center in Tucson had its first two patients of the season earlier this week.

The Arizona Republic reports that 270 snakebites were reported statewide last year, with nearly half of them in Maricopa County.

The last fatal snakebite in the state was a 63-year-old Chino Valley woman, who died in October.
