(Reuters) -The U.S. Centers for Disease Control and Prevention on Friday confirmed two additional cases of bird flu in Colorado poultry farm workers.

Last week, Colorado reported four confirmed infections of H5N1 bird flu and was checking on the status of a fifth suspected case.

The two new cases were in poultry workers with exposure to infected poultry during depopulation and disposal activities, the CDC said on Friday.

The cases are part of an outbreak of H5N1 bird flu that has been spreading globally in wild birds, infecting poultry and various species of mammals.

The CDC said on Monday that they deployed a nine-member field team comprising epidemiologists, veterinarians, clinicians and an industrial hygienist to support Colorado’s assessment of the outbreak and the human cases.
