Health experts say the H1N1 virus is targeting young children more than anyone else.
Of tracked flu hospitalizations in Colorado, children ages 5 to 17 make up about 7% of seasonal flu hospitalizations, but for H1N1 cases, the number triples.
As for the elderly, last year they made up 43% of seasonal flu hospitalizations, but for H1N1 cases, they're only making up 7%.
Mesa County Health Department officials say the Centers for Disease Control is now urging parents to get their children vaccinated, but some parents are still not sold on the idea.
There is still no final official word yet as to when the H1N1 virus vaccine will be ready.
Health Department officials say as for now, the most common symptom to look for is fever, and if you or your child has one, to stay home for at least 24 hours until the fever has subsided.
