CDC continues to respond to the outbreak of H5N1 bird flu in dairy cows that has so far affected 163 herds in 13 states, with eight human cases confirmed by CDC as of July 18. Recent CDC activities include finalizing agreements with eight commercial laboratories to develop tests to identify A(H5) infections in people; posting information that describes and illustrates the procedure for collecting, storing, and shipping conjunctival specimens for testing using the A(H5) assay; and reporting that extensive efforts to sequence or isolate virus from a human case in Colorado were unsuccessful.
