Children and infants are more susceptible to the illness.

A virus with the potential to make vulnerable populations deathly ill is on the rise in California. Higher than normal levels of the virus have been found in the wastewater of several towns across the state, putting public health officials on high alert due to both the contagious nature of the rotavirus and how sick it can make children and infants.

Fortunately, with a heads-up about the spreading virus, many families and health agencies can be proactive about the illness.

The Sacramento Bee reports that there has been a rise in cases of rotavirus. According to the publication, WastewaterSCAN shows "high concentrations" of the virus in places like Santa Cruz, Marin, San Jose, and Redwood City.

Moderate concentrations of the virus have been found in other places, like Novato, Vallejo, Sacramento, San Francisco, Davis, and Sunnyvale.

The findings are especially concerning for parents with children and infants, who are more susceptible to the illness.

The California Department of Public Health's website says that the virus is responsible for most cases of severe diarrhea in that age group in the U.S., and it remains one of the major drivers of childhood deaths worldwide. This is because it causes severe dehydration, which can sometimes require medical attention to be resolved.

Fortunately, there is a vaccine, and the U.S. Centers for Disease Control and Prevention says that many children receive six doses in the first eight months of life.

Trying to avoid the illness? According to the Mayo Clinic, unwashed hands are one of the biggest spreaders of the virus. That's because it is found in fecal matter, which can be spread from person to person through touch, making it very important to always wash your hands after using the bathroom and before eating.

That being said, the virus spreads very quickly, and even the smallest and shortest contact with it can cause an infection.
