AT A GLANCE
H1N1 influenza is as contagious as seasonal flu. It's mainly spread by coughing or sneezing and infected droplets coming into contact with another person.
Symptoms: Fever, cough, sore throat, body aches, headache, chills, fatigue. Patients may have diarrhea and vomiting. Symptoms are usually mild to moderate; most patients fully recover.
Precautions: Cover coughs and sneezes with an elbow, sleeve or tissue. Coughing into hands can spread germs to others. Wash hands often with soap and water, or use an alcohol-based hand cleaner. Avoid touching your eyes, nose and mouth, even after washing your hands. Avoid close contact with sick people.
Treatment: Most people recover without medical attention. Seek immediate care if you have warning signs such as trouble breathing; severe or persistent vomiting; pain or pressure in the chest or abdomen, sudden dizziness or confusion. Warning signs for a child include fast breathing, bluish or gray skin, persistent vomiting.
