If you were in a country with a COVID-19 outbreak and feel sick with fever, cough, or difficulty breathing, within 14 days after you left, you should

• Seek medical advice – Call ahead before you go to a doctor’s office or emergency room. Tell them about your recent travel and your symptoms.
• Avoid contact with others.
• Not travel on public transportation while sick.
• Cover your mouth and nose with a tissue or your sleeve (not your hands) when coughing or sneezing.
• Wash hands often with soap and water for at least 20 seconds to avoid spreading the virus to others.
• Wash your hands with soap and water immediately after coughing, sneezing or blowing your nose.
• If soap and water are not readily available, you can use an alcohol-based hand sanitizer that contains 60%–95% alcohol. Always wash hands with soap and water if hands are visibly dirty.
