Although the name 'swine flu' brings up a lot of extra fear and worry, it is important to note that swine flu is just an influenza A H1N1 virus.
That means that it is just another type of flu virus, just like that causes our typical seasonal flu symptoms. The big difference is that the current swine influenza A (H1N1) virus is new and most of us don't have any immunity to it. That is why it so easily became a pandemic virus (with the ability to cause a global outbreak), because it could easily spread from person to person.
After a summer of declining flu cases, instances of swine flu began to rise again in early fall and there are now widespread swine flu cases in most of the US, as you can see on this swine flu map.
Swine Flu Symptoms
According to the CDC, like seasonal flu, symptoms of swine flu infections can include:
fever, which is usually high, but unlike seasonal flu, is sometimes absent
cough
runny nose or stuffy nose
sore throat
body aches
headache
chills
fatigue or tiredness, which can be extreme
diarrhea and vomiting, sometimes, but more commonly seen than with seasonal flu
Signs of a more serious swine flu infection might include pneumonia and respiratory failure.
If your child has symptoms of swine flu, you should avoid other people and call your pediatrician who might do a rapid flu test to see if he has an influenza A infection. Further testing can then be done to see if it is a swine flu infection. (Samples can be sent to local and state health departments and the CDC for confirmation of swine flu, especially if a child is in the hospital.)
Swine Flu High Risk Groups
With regular seasonal flu, young children and the elderly are usually thought to be most at risk for serious infections, in addition to people with chronic medical problems. Swine flu high risk groups, people who are thought to be at risk for serious, life-threatening infections, are a little different and can include:
pregnant women
children under age two years old
people with chronic medical problems, such as chronic lung disease, like asthma, cardiovascular disease, diabetes, and immunosuppression
children and adults with obesity
It is important to keep in mind that unlike seasonal flu, more than half of the hospitalizations and a quarter of the deaths from swine flu are in young people under the age of 25.
Serious Swine Flu Symptoms
More serious symptoms that would indicate that a child with swine flu would need urgent medical attention include:
Fast breathing or trouble breathing
Bluish or gray skin color
Not drinking enough fluids
Severe or persistent vomiting
Not waking up or not interacting
Being so irritable that the child does not want to be held
Flu-like symptoms improve but then return with fever and worse cough
Swine Flu Symptoms vs. a Cold or Sinus Infection
It is important to keep in mind most children with a runny nose or cough will not have swine flu and will not have to see their pediatrician for swine flu testing.
This time of year, many other childhood conditions are common, including:
fall allergies - runny nose, congestion, and cough
common cold - runny nose, cough, and low grade fever
sinus infections - lingering runny nose, cough, and fever
strep throat - sore throat, fever, and a positive strep test
What You Need To Know
Swine flu likely spreads by direct contact with respiratory secretions of someone that is sick with swine flu, like if they were coughing and sneezing close to you.
People with swine flu are likely contagious for one day before and up to seven days after they began to get sick with swine flu symptoms.
Droplets from a cough or sneeze can also contaminate surfaces, such as a doorknob, drinking glass, or kitchen counter, although these germs likely don't survive for more than a few hours.
Anti-flu medications, including Tamiflu (oseltamivir) and Relenza (zanamivir), are available to prevent and treat swine flu in high risk children.
The latest swine flu news from the CDC includes advice that daycare centers should do daily health checks, separate ill children until they can go home, encourage kids to stay home until they are free of fever for at least 24 hours, encourage proper hand-washing, and teach kids to properly cover their coughs and sneezes to help everyone avoid the flu.
