Rattlesnakes! A threat along the Wasatch Front. And it's not even summer yet.

In the hospital tonight-- a 21-year-old woman and an 18-month-old baby. Both are recovering from multiple bites.

A sign at the Fort Fouglas Cemetery, just east of University of Utah's Research Park, clearly identifies a potential risk for those visiting the cemetery.

21-year-old Elizabeth Hymas was bitten by a baby rattlesnake while she was hiking in Logan. Because she's allergic to anti-venom serum, she ended up in ICU at University Hospital.

Elizabeth said she picked up what appeared to be a dead snake. It bit her on the thumb.

ELIZABETH HYMAS: "MY HAND SWELLED UP QUITE A BIT - QUICK. IT STAYED LOCALLY IN MY ARM BUT I WAS IN ICU THE FIRST COUPLE OF DAYS AND I'VE BEEN IN THE HOSPITAL EVER SINCE SATURDAY."

At Primary Children's Hospital, a 20-month-old month child is recovering from two bites on his hand. Antonio Avile was out playing at his grandmother's house in Montezuma Creek.

CHARLOTTE AVILE, ANTONIO'S MOTHER: "HIS WHOLE HAND WAS JUST SWOLLEN. IT WAS SWOLLEN UP TO HIS ELBOW. IT LOOKED HIDEOUS."

While nobody found anything, Antonio's mother believes her son may have picked up a rattler which wandered into the yard. It too was probably a younger snake.

The Utah Poison Control Center doesn't normally get calls on snakebites this early in the year, but Barbara Crouch says so far they've received six calls in only seven days.

BARBARA CROUCH, DIR., UTAH POISON CONTROL CENTER: "IT'S VERY UNUSUAL. WE'VE ALMOST HAD OUR QUOTA FOR THE ENTIRE YEAR IN THE LAST WEEK OF SNAKEBITES."

Experts say baby rattlers right now are dangerous because they haven't yet learned how to control the release of venom. While an adult snake releases a small amount, a baby snake empties all of its venom.
