A second health worker in contact with the Missouri patient who tested positive for bird flu also developed symptoms but wasn’t tested for influenza, the CDC said Friday.

A patient in Missouri who was hospitalized after an infection with bird flu had the H5N1 strain of the virus, the US Centers for Disease Control and Prevention confirmed Friday.

This is the second health care worker to report that they developed symptoms after being in contact with the patient. The first was tested for flu, and the results were negative, the CDC said. The agency says the risk of H5N1 to the general population remains low.

The number of people who were in contact with the hospitalized bird flu patient in Missouri and developed symptoms is now up to three, officials said. All three have recovered. The other two symptomatic cases included a healthcare worker who tested negative for influenza and a household contact of the patient who developed symptoms at the same time as the hospitalized patient,

Health officials identified three contacts, including two healthcare workers, who were closely monitored after a bird flu patient in Missouri was recently hospitalized.
