Mesa County health officials are warning of a gastrointestinal illness that looks a lot like the norovirus. Mesa County Public Health issued a guidance Tuesday about prevention methods after detecting cases of the contagious gastrointestinal virus from child-care facilities. The virus has since made its way to some students at all levels throughout School District 51, bringing to mind the norovirus issues that ran through District 51 in November of 2019. Ideally, the district would rather not deal with norovirus again. But if itâs going to, now is one of the best times. âWe had a four-day weekend last week, so that kept kids away from each other,â said Emily Shockley, spokesperson for District 51. âNow we have spring break next week, too.â
