California reports 4 more probable H5 cases in dairy workers

The California Department of Public Health (CDPH) today reported four more probable avian flu infections in dairy workers, as it awaits final confirmation from the US Centers for Disease Control and Prevention (CDC) on an earlier probable case identified in state testing.

The newly identified potential cases came from proactive testing over a 3-day period, the CDPH said. All of the sick people had contact with infected cattle on nine different farms.

So far, all patients have had mild symptoms such as conjunctivitis. None of the people were hospitalized.
