"This is in stark contrast with seasonal influenza, where about 90 percent of severe and fatal cases occur in people 65 years of age and older," he said. "It's important to be aware that this virus can challenge even the most robust of immune systems."

Yet one thing remains exactly the same between seasonal influenza and H1N1 ”the way they spread.

"This virus spreads through person-to-person contact, through coughing and sneezing, and touching contaminated objects and then your mouth, nose or eyes," Dr. Mamtani said. "In this case, we know what we need to do to help prevent its spread."

Dr. Al-Khal recommended the following preventative measures:

Cover your nose and mouth with a tissue every time you sneeze and cough, and throw the tissue in the trash

Wash your hands with soap and water for 15 to 20 seconds, or, use an alcohol-based sanitizer or hand wipe to clean your hands, often

Avoid touching your eyes, nose or mouth directly with your hand when outside

Try to avoid contact with sick people

If you are sick with flu-like symptoms ”unusual tiredness, headache, runny nose, sore throat, shortness of breath or cough, loss of appetite, aching muscles, diarrhoea or vomiting ”seek medical care
