But severe illnesses such as pneumonia and respiratory failure and even deaths have been reported with swine flu infection in people. Like seasonal flu, swine flu can worsen underlying chronic medical conditions.There is no vaccine available right now to protect against swine flu. But there are everyday actions that can help prevent the spread of germs that cause respiratory illnesses like influenza. These include covering your mouth and nose with a tissue when coughing or sneezing and then throwing the tissue in the trash; washing hands often with soap and water or using alcohol-based hand cleaners; and trying to avoid close contact with sick people.
