The Flu

Influenza (flu) is infection of the lungs and airways with one of the influenza viruses. The flu is not the same as the common cold. The flu is a more serious infection such as the swine flu (H1N1) or the bird flu (H5N1).

Influenza virus is spread by inhaling droplets that have been coughed or sneezed out by an infected person or by having direct contact with an infected person's secretions. That's why I have been repeating 49 times that one should practise cough/sneeze etiquette. Please don't blame the cold weather for it. The flu is caused by a virus. I repeat, a virus.

So, what are the symptoms of the flu? Sore throat, runny nose, cough, chills, fever, body aches and pain, headache, and watery eyes. Yes, the symptoms are the same as the common cold. The symptoms for the flu could start 24 to 48 hours after infection or it could begin suddenly!

How to treat it? All you need to do is to rest adequately, drink plenty of fluids, and avoid exertion. Fever may be treated with acetaminophen (paracetamol, as it is commonly known here in Malaysia). Alternatively, the flu may be treated with antiviral drugs.

And since the flu is a virus infection, antibiotics will not cure you. Antibiotics are to be taken if it is a bacterial infection, such as a bacterial pneumonia infection.

Should I say it again? Practise cough/sneeze etiquette!
