I received this from a listserve for the Project for Monitoring Emerging Diseases (ProMED). It contains useful information related to the epidemic of avian flu in wild birds and poultry and the low risk of infection in humans in Colorado. I’ve observed several dead pelicans and gulls in Larimer County in recent days. > From: ProMED <pro...@isid.org> > > Sent: Friday, April 29, 2022 3:56 PM > To: Komar, Nick (CDC/DDID/NCEZID/DVBD) <n...@cdc.gov> > Subject: PRO/AH/EDR> Avian influenza, human (14): Americas (USA) H5N1 > > > > AVIAN INFLUENZA, HUMAN (14): AMERICAS (USA) H5N1 > ************************************************ > A ProMED-mail post > http://www.promedmail.org > ProMED-mail is a program of the > International Society for Infectious Diseases > http://www.isid.org > > Date: Thu 28 Apr 2022 21:46 EDT > Source: KKTV [edited] > https://www.kktv.com/2022/04/29/colorado-man-tests-positive-h5-bird-flu-1st-human-case-us-cdc-reports-public-health-risk-assessment-remains-low/ > > > > The 1st human case associated with the H5 bird flu in the United > States was detected in a Colorado man.
