CTV.ca offers answers to your most frequently asked questions about how to spot swine flu in kids, when to treat it at home and when to call your doctor.

How do I know if my child has swine flu or a regular flu?

Without laboratory testing, it's difficult to tell the difference between swine flu and seasonal flu. And with the strain established in communities across Canada, doctors are no longer testing to determine which types of flu people have. 

But because the H1N1 is circulating so widely and "pushing out" other strains, chances are good that if you catch the flu in the next couple of months, you've caught swine flu. 

The symptoms of swine flu in kids older than five are similar to those of regular flu. They are:

  • fever of 38 C (100.4 F) or higher when measured orally
  • coughing and sore throat
  • fatigue
  • lack of appetite
  • sometimes vomiting and diarrhea, especially in younger children

Babies and toddlers under the age of five can have different symptoms: 

  • Fever may be the only symptom. Toddlers and babies usually have higher temperatures, often over 39.5C (103.1F) when measured orally 
  • About half of children under three years old have symptoms that include nausea, vomiting, diarrhea and stomach pain
  • Ear infections and red, sore eyes are more frequent in young children
  • Some babies may not be able to drink fluids or breastfeed
  • Stiff neck may appear in some babies
  • Toddlers and babies may have a hoarse cry and a barking cough.

The symptoms of the common cold, meanwhile, usually include stuffy or runny nose, sore throat and sneezing, and usually are not accompanied with fever, chills or body aches.

When should we see a doctor?

Remember, in the overwhelming majority of cases, swine flu causes illness that can be easily treated at home with bedrest and fever-reducing medication. Yes, it can often be a nasty infection, but complications are rare, especially in otherwise healthy kids.

But, you should seek medical care if your child or teen develops flu symptoms and has any of the following medical conditions:

  • lung or heart disease
  • any chronic health problem that requires regular medical attention
  • an illness that might affect their immune systems, such as diabetes, cancer, or HIV/AIDS
  • is pregnant

If your child has flu symptoms and then develops any of the following warning signs, you should call your child's doctor for advice:

  • Severe or persistent vomiting
  • Not drinking enough fluids. Goes to the bathroom less often than every six hours while awake if two years of age or older
  • Not waking up or not interacting. Loses interest in playing, watching TV, eating or drinking
  • Being so irritable that the child does not want to be held and cries a lot
  • Flu symptoms improve, but then return with fever and worse cough

Call 911 right away if your child:

  • has severe trouble breathing and it is not caused by a stuffy nose
  • has blue lips or hands, suddenly becomes pale, or has cold legs up to their knees
  • is so sleepy that he doesn't respond when you try to get him up, or isn't able to move
  • seems confused
  • has a seizure

"Parents should be really concerned if their child's fever is quite high and isn't coming down, or if they continue to have respiratory distress even when the fever is down," says Dr. Ken Farion, an emergency room doctor at The Children's Hospital of Eastern Ontario in Ottawa.

He says many times, symptoms of swine flu will come on suddenly in children, such as a fever that spikes quickly. That alone is not cause for worry.

He advises that parents first try to treat their child's fever -- with the appropriate amount of medication. If the fever goes down and the child is looking better, they should remain at home. But if they don't respond to medication, or they develop the more worrying signs mentioned above, they should seek medical care.

When should I keep my child home from school?

If your child has a fever, they should stay at home, even if they seem to have a mild case. That way your child won't infect other children, including those who could develop severe illness.

In most kids, the flu will run its course in about a week, though the cough and fatigue can last a few weeks in some patients.

How long should I keep my children at home if they have mild cases?

People infected with swine flu -- or any flu for that matter -- can infect others from one day before showing symptoms to up to seven days afterward. Just like with seasonal flu, swine flu is most contagious during the first days a patient starts showing symptoms, when they have "a high viral load."

Most experts agree it's best to keep sick kids home for at least five days or until they are able to resume daily activities, whichever is shorter.

If your child's symptoms do not improve after a week, call your doctor, as your child may have developed complications.

How do I treat flu in my kids?

  • To bring down the fever, use acetaminophen (Tylenol) according to instructions on the label or advice from a health care provider.
  • Ibuprofen can treat muscle aches but should not be used for babies younger than six months of age.
  • Children younger than 18 years of age should not take any products containing acetylsalicylic acid (ASA)
  • Encourage your child to rest or engage in quiet activities. Do not allow them to socialize with others.
  • Offer water or juice often
  • Dress your child in lightweight clothing and keep room temperature at 20C (68F). Do not use cool baths or alcohol rubs
  • Try saline nose drops to help relieve stuffy nose or cough

How can I protect my children from getting sick?

Swine flu is spread from person to person in the same way as seasonal flu: through coughing or sneezing and by touching surfaces contaminated with infected droplets.

Proper hand hygiene is one of the best ways to guard against the flu. Flu viruses can live on your hands for up to five minutes, and can live on hard surfaces, like countertops and telephones, for up to two days. To reduce transmission:

  • encourage your kids to clean their hands and clean them often to keep them and others from passing the flu. They should clean their hands after sneezing or coughing, before and after eating, after going to the washroom, and after playing outside.
  • keep alcohol-based sanitizers handy in gel or wipe form, at home or in their backpack for times when they can't wash their hands.
  • teach your children to cough or sneeze into their arms or sleeves
  • encourage your child not to share personal items or drinks
  • consider having your child vaccinated against swine flu once the vaccine becomes available in your area
