 Five Coloradans have been diagnosed with bird flu, and Governor Jared Polis has declared a disaster emergency after that avian flu has impacted poultry, dairy cattle, and that handful of humans. State epidemiologist Dr. Rachel Herlihy says one of the main symptoms they're seeing is pink eye and flu-like symptoms. If you have any of those symptoms after being in contact with poultry or cattle, call the Colorado Department of Public Health and Environment.
