The symptoms of this new H1N1 flu virus in people are similar to the symptoms of seasonal flu and include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. A significant number of people who have been infected with this new H1N1 virus also have reported diarrhea and vomiting. The high risk groups for novel H1N1 flu are not known at this time but it’s possible that they may be the same as for seasonal influenza. People at higher risk of serious complications from seasonal flu include people age 65 years and older, children younger than 5 years old, pregnant women, people of any age with chronic medical conditions (such as asthma, diabetes, or heart disease), and people who are immunosuppressed (e.g., taking immunosuppressive medications, infected with HIV).
Avoid Contact With Others
If you are sick, you may be ill for a week or longer. You should stay home and avoid contact with other persons, except to seek medical care. If you leave the house to seek medical care, wear a mask or cover your coughs and sneezes with a tissue. In general you should avoid contact with other people as much as possible to keep from spreading your illness. At the current time, CDC believes that this virus has the same properties in terms of spread as seasonal flu viruses. With seasonal flu, studies have shown that people may be contagious from one day before they develop symptoms to up to 7 days after they get sick. Children, especially younger children, might potentially be contagious for longer periods.
Protect Yourself, Your Family, and Community
Stay informed. Health officials will provide additional information as it becomes available.
Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also effective.
Avoid touching your eyes, nose or mouth. Germs spread this way.
Try to avoid close contact with sick people.
If you are sick with a flu-like illness, stay home for 7 days after your symptoms begin or until you have been symptom-free for 24 hours, whichever is longer.
Keep away from other household members as much as possible. This is to keep you from infecting others and spreading the virus further.
