BRYAN, Texas -

Brazos County Health Department Two brothers living in Brazos County who contracted E. coli remained in fair condition at Texas Children's Hospital.

The brothers -- 4-year-old Jack Melton and 17-month-old Noah Melton -- contracted E. coli strain 0157H7, which turned into hemolytic-uremic syndrome.

The strand affects about 100,000 people in the U.S. each year. Hemolytic-uremic syndrome, or HUS, is a condition that results from the premature destruction of red blood cells, which can cause kidney failure.

At least three others have contracted the same E. coli strain.

According to the Center for Disease Control, symptoms include stomach cramps, diarrhea, and vomiting. The usual recovery time is about one week.

To avoid contracting E. coli, doctors recommend frequently washing your hands, avoiding unpasteurized dairy products, and cooking meats thoroughly.
