Rachel Herlihy, MD, MPH, the Deputy Chief Medical Officer and Chief Epidemiologist at the Colorado Department of Public Health, specified that while the total danger to human beings is low, it differs based upon direct exposure levels.
She kept in mind that roughly 70 farm employees in Colorado have actually been under observation, and to date, none have actually displayed signs.

Baldwin stated there are still numerous unknowns, consisting of the length of the incubation duration in livestock, the system of transmission, the length of time the animals shed the infection, and whether H5N1 postures a danger to nonlactating livestock or other animals types.
