Swine flu is a disease that pigs (swine) can get. It can spread within a group of pigs that live together. The pigs may have mild symptoms, or they may have breathing problems, fever, coughing, sneezing, and watery eyes and nose. The main swine flu viruses infecting pigs currently are H1N1, H3N2, and H1N2, though other viruses may also cause swine flu in pigs.
Viruses can change and jump from one kind of animal to another, such as from cattle to deer, or from animals to people such as from pigs or birds to humans. The swine flu virus can be passed to people who work with or are exposed to the infected pigs.
Swine flu in humans is an infection currently caused by the H1N1v or H3N2v virus. The “v” (variant) means that the virus changed from infecting only pigs to also being able to infect humans. A person can pass a swine flu infection from these viruses to another person.
Infection with swine flu virus is like flu from any other virus. Flu symptoms may be mild, or flu can be more serious and lead to ear, sinus, and chest infections. Pneumonia can also be a result of the flu. It can be caused by the flu virus itself or by bacteria infecting lung tissues that have been damaged by the virus. Children whose immune systems are weak and children with chronic medical problems such as heart or lung disease or diabetes are at risk for more severe symptoms or problems.
The H1N1v or H3N2v virus can be passed from swine to humans through:
Swine flu can be passed from an infected person to another person, just like any other cold or flu. Your child can be exposed by being within 6 feet (2 meters) of an infected person who has been around swine. The virus is in mucus and saliva and can spread to others when someone coughs or sneezes. People can also get swine flu if they touch something with the flu virus on it such as door handles or hands, and then touch their mouth, nose, or eyes.
Swine flu is not spread by eating pork.
Swine flu symptoms are the same as seasonal flu. Your child may feel fine one hour and feel sick the next. Flu symptoms may be different from person to person. Some of the common symptoms include:
Swine flu symptoms usually last 3 to 7 days. Your child may start feeling better after the first 2 days or so.
Your child’s healthcare provider will ask about your child’s symptoms and whether your child has been around swine and examine your child. The diagnosis is usually based on your child’s symptoms. There are lab tests for flu, but in most cases, no test is needed.
Usually you can treat the symptoms for any type of flu at home.
Your healthcare provider can prescribe antiviral medicine that may make flu symptoms less severe. It is usually only prescribed if your child is at high risk for complications. The medicine can be taken as a pill or nasal spray. Usually it is taken for only a few days after your child gets sick. Even if your child takes antiviral medicine, your child can pass the flu virus to other people. It is still important for your child to wash hands often and cover the mouth and nose when coughing or sneezing.
Talk to your healthcare provider right away if your child has symptoms of the flu and:
Ask your child’s healthcare provider:
Make sure you know when your child should come back for a checkup. Keep all appointments for provider visits or tests.
The flu vaccine is the best way to help prevent the flu. Stay up to date with the recommended immunizations (shots) for your child including flu and COVID-19. Ask your healthcare provider about any other vaccines your child or your family may need.
The vaccine itself will not give your child the flu. However, if your child was exposed to the flu just before getting the vaccine, your child may still get sick. If your child does get the flu after getting the vaccine, your child will not get as sick as without the vaccine.
The flu vaccine is recommended for children 6 months and older. It’s especially important for those with a chronic illness. The shot contains killed virus and is safe for everyone age 6 months and older. The flu vaccine is usually given as a shot in the arm. It may be given as a nasal spray for some people.
Your child should get a new flu shot every year because the vaccine wears off over time and because it is changed each year to protect against the current year’s most likely flu strains. It’s best to get the new vaccine as soon as it’s available each year before the start of flu season. However, if the vaccine is still available, it can be helpful to get it anytime during the flu season. Flu season usually starts in October and can last through May.
Flu seasons can vary from region to region. If your child is at high risk for infection and will travel to an area where your child might be exposed to the flu, make sure your child has an up-to-date flu shot before the trip.
Other things to help avoid getting the flu include:
Your child should not go to school or work while sick.
