Colorado health officials are awaiting test results for what they call five suspected cases of Swine Flu.
The Colorado Department of Public Health and Environment says it expects the results to come back sometime today from the Centers for Disease Control and Prevention.
Officials are not disclosing where the suspected cases are.
The Utah Department of Health has also sent one flu sample in to be tested, those results are expected to come back tomorrow.
Officials classify a case as probable when it receives a flu sample that the public health lab is unable to identify.
