Kern County Public Health announced an ongoing investigation Saturday into a person who possibly came in contact with a cow infected with bird flu. An individual working at a dairy farm has potentially been infected with H5N1 bird flu after coming in contact with a cow carrying the virus,

Hospital workers reported respiratory symptoms after encountering a Missouri patient with H5N1 who had not been exposed to farm animals. Officials say bird flu transmission is unlikely.

Both patients were dairy workers whose illnesses were mild. Investigators are continuing to evaluate the contacts of a Missouri patient who had no exposure to animals.
