About the condition
What is Influenza A (H1N1)?
Influenza A (H1N1-2009) (also described as 2009 Influenza A (H1N1), and previously referred to as "new strain of swine flu") is a new strain of influenza virus that spreads from human to human. Influenza A (H1N1) is a viral respiratory disease that presents with flu-like symptoms, and it has been found to infect more children and young adults than the older population.
How to reduce the risk for children?
Practise good personal hygiene and be socially responsible by :
Washing your hands regularly and thoroughly with soap and water, especially before touching your eyes, nose or mouth.
Cover your mouth and nose with tissue whenever you need to cough or sneeze.
Avoid close contact with sick people or someone who has H1N1 flu.
Use alcohol-based hand cleaner
Reduce unnecessary social contacts and avoidance whenever possible of crowded settings
Facemasks may help to reduce the risk of getting influenza

Decreased or no movement/lethargic
Diagnosis and Treatment Options
What is expected at hospital?
Step1: Your child will be seen in Fever Facilities at a Emergency Department. A nurse will take your temperature and other parameters. Your will be asked for your travel history and symptoms.
Step 2: Your child will be see by a doctor from Children's Emergency. The consultation aims to assess your child's condition as well as risk factor for more severe H1N1 disease. In the absence of risk factors and complication, you child will be treated symptomatically and discharge as appropriate.
Step 3: Nasal swab for H1N1 testing will be done for your child if your child is deemed at higher risk for more severe H1N1 disease.
Step 4: A doctor or nurse will take a nasal or throat swab sample from you. Your child will be asked to tilt his/her head backwards while the doctor or nurse inserts a swab into the nostrils or to the back of his/her throat. The swab will be held for a few seconds and he/she may experience a slight discomfort.
Step 5: After the swab has been taken, the sample will sent to the laboratory for processing. This will take approximately 36 hours.
Step 6: Your child will be discharged after the swab if his/her condition is stable. You will be informed of the result when it is available.
Treatment for H1N1 is like for other influenza viruses. Rest and plenty of fluids are important for speedy recovery. Symptomatic treatment for fever, sore throat, runny nose and cough may alleviate the discomfort
Your doctor will decide if your child needs antiviral drugs such as Tamiflu® (oseltamivir) or Relenza® (zanamivir). Antiviral drugs are prescription pills, liquids or inhalers that fight against the flu by keeping the germs from growing in your body. These medicines can make your child feel better faster and make their symptoms milder.
Can influenza antiviral drugs be used in children?
Oseltamivir(Tamiflu) and zanamivir(Relenza) can be used for children, but as most of them recover without any medications, they are now not routinely prescribed. Children at high risk of complications from influenza, like those with chronic lung and heart disease, immunocompromised children, or those presenting with more complicated and severe symptoms would be given these anti-viral drugs. These medicines work best when started soon after symptoms begin within 2 days and for antiviral treatment it is usually for a period of 5 days.
Will there be any side-effect after taking influenza antiviral drugs?
The common side-effects of influenza anti-viral drugs are nausea and vomiting. In children and adolescents, there have been reports of unusual behaviour, like self-injury and confusion after taking oseltamivir. Rarely, severe allergic skin reaction may occur.
