Matt Hildner of the Pueblo Chieftain reported that Alamosa County health officials are investigating an outbreak of salmonella that’s led to the hospitalization of four people and may have infected up to 74 people.  In addition to the 18 cases that have been confirmed through laboratory testing, Geiser said the county is also investigating 56 cases with symptoms of the illness although they have yet to be laboratory confirmed.  Geiser said she had never seen an outbreak of salmonella in her 12 years with the county.  "We have an employee that’s been here 25 years and she hasn’t seen anything like this either," she said.  Geiser said the cases have included a number of children, in part because adults are able to get over the infection more easily.
