The 11 people who had direct contact with the animals at Hess-Hathaway Park will be monitored by the Oakland County Health Division for 10 days. One person who has flu-like symptoms was tested for the highly pathogenic avian influenza. Results from the state lab are pending.

Last month, state health officials detected bird flu in a backyard flock in Jackson County, plus two commercial poultry facilities in Ottawa County.

Two people are sick in Oakland County and nine others are being monitored after they had contact with H5N1 bird flu from an infected backyard flock.
