Swine Flu

Everything you need to know.

Causes of Swine Flu

Swine flu is contagious, and it spreads in the same way as the seasonal flu. When people who have it cough or sneeze, they spray tiny drops of the virus into the air. If you come in contact with these drops or touch a surface (such as a doorknob or sink) that an infected person has recently touched, you can catch H1N1 swine flu.

Despite the name, you can’t catch swine flu from eating bacon, ham, or any other pork product.

Swine Flu Symptoms

People who have swine flu can be contagious one day before they have any symptoms, and as many as 7 days after they get sick. Kids can be contagious for as long as 10 days.

Most symptoms are the same as seasonal flu. They can include:

Like seasonal flu, swine flu can lead to more serious complications, including pneumonia and respiratory failure. And it can make conditions like diabetes or asthma worse. If you have symptoms like shortness of breath, severe vomiting, abdominal pain, dizziness, or confusion, call your doctor or 911 right away.

Tests for Swine Flu

It’s hard to tell whether you have swine flu or seasonal flu, because most symptoms are the same. People with swine flu may be more likely to feel nauseous and throw up than people who have seasonal flu. But a lab test is the only way to know for sure. Even a rapid flu testyou can get in your doctor’s office won’t tell you for sure.

To test for swine flu, your doctor takes a sample from your nose or throat. You may not need to be tested. The CDC says the people who need to be tested are those in the hospital or those at high risk for getting life-threatening problems from the flu, such as:

  • Children under 5 years old
  • People 65 or older
  • Children and teens (under age 18) who are getting long-term aspirin therapy, and who might be at risk for Reye’s syndrome after being infected with swine flu. Reye’s syndrome is a life-threatening illness linked to aspirin use in children.
  • Pregnant women
  • Adults and children who have chronic lung, heart, liver, blood, nervous system, neuromuscular, or metabolic problems
  • Adults and children who have suppressed immune systems (including those who take medications to suppress their immune systems or who have HIV)
  • People in nursing homes and other long-term care facilities

Vaccine for Swine Flu

The same flu vaccine that protects against seasonal flu also protects against the H1N1 swine flu strain. You can get it as a shot or as a nasal spray. Either way, it "teaches" your immune system to attack the real virus.

Besides a flu shot, there are other things you can do to stay healthy:

  • Wash your hands throughout the day with soap and water. Sing the "Happy Birthday" song twice to make sure you’ve washed long enough. Or use an alcohol-based hand sanitizer.
  • Don’t touch your eyes, nose, or mouth.
  • Avoid people who are sick.
