H1N1 (Swine Flu) Questions and Answers
What is swine flu?
Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza viruses. Outbreaks of swine flu happen regularly in pigs. People do not normally get swine flu, but human infections can and do happen. Most commonly, human cases of swine flu happen in people who are around pigs but it’s possible for swine flu viruses to spread from person to person also.
Are there human infections with swine flu in the U.S.?
In late March and early April 2009, cases of human infection with swine influenza A (H1N1) viruses were first reported in Southern California and near San Antonio, Texas. The Centers for Disease Control (CDC) and local and state health agencies are working together to investigate this situation.
Is this swine flu virus contagious?
CDC has determined that this virus is contagious and is spreading from human to human. However, at this time, it not known how easily the virus spreads between people.
What are the signs and symptoms of swine flu in people?
The symptoms of swine flu in people are similar to the symptoms of regular human flu and include fever, cough, sore throat, body aches, headache, chills and fatigue. Some people have reported diarrhea and vomiting associated with swine flu. In the past, severe illness (pneumonia and respiratory failure) and deaths have been reported with swine flu infection in people. Like seasonal flu, swine flu may cause a worsening of underlying chronic medical conditions.
How do you catch swine flu?
Spread of swine flu can occur in two ways: Through contact with infected pigs or environments contaminated with swine flu viruses. Through contact with a person with swine flu. Human-to-human spread of swine flu has been documented also and is thought to occur in the same way as seasonal flu. Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.
Are there medicines to treat swine flu?
Yes. Public health officials recommend the use of oseltamivir or zanamivir for the treatment and/or prevention of infection with these swine influenza viruses. Antiviral drugs are prescription medicines (pills, liquid or an inhaler) that fight against the flu by keeping flu viruses from reproducing in your body. If you get sick, antiviral drugs can make your illness milder and make you feel better faster. They may also prevent serious flu complications. For treatment, antiviral drugs work best if started soon after getting sick (within two days of symptoms).
How long can an infected person spread swine flu to others?
People with swine influenza virus infection should be considered potentially contagious as long as they are symptomatic and possible for up to 7 days following illness onset. Children, especially younger children, might potentially be contagious for longer periods.
What can I do to protect myself from getting sick?
There is no vaccine available right now to protect against swine flu. There are everyday actions that can help prevent the spread of germs that cause respiratory illnesses like influenza. Take these everyday steps to protect your health:
Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also effective. Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
Try to avoid close contact with sick people.
If you get sick with influenza, DHSS recommends that you stay home from work or school and limit contact with others to keep from infecting them. Avoid touching your eyes, nose or mouth. Germs spread this way.
What should I do if I get sick?
If you have recently traveled to areas currently reporting swine flu cases, or have been in direct contact with someone who has, and believe you are becoming ill with influenza-like symptoms, contact a local healthcare provider. Symptoms include fever, body aches, runny nose, sore throat, nausea, or vomiting or diarrhea, you may want to contact their health care provider, particularly if you are worried about your symptoms.
