ATLANTA (AP) – Thanks to swine flu, there’s a little less hugging and kissing in the United States.

A survey this week found that about one in 10 Americans have stopped hugging and kissing close friends or relatives because of concerns about swine flu. About the same number have stopped shaking hands.

Health officials have emphasized other measures to prevent spread of the virus, like washing hands and using hand sanitizers. The survey found about two-thirds of Americans are taking such steps.

The telephone survey of more than 1,000 people was done by Harvard School of Public Health, with funding from the Centers for Disease Control and Prevention.

The CDC said Friday the number of swine flu cases in the U.S. is now over 1,600.
