H5N1 is back

Remember SARS (Severe Acute Respiratory Syndrome) seven years ago? Well, it's back!

Hong Kong has confirmed its first case of human bird flu in seven years and raised the bird flu alert to ‘serious’. Read here.

A 59-year-old woman had tested positive for H5N1 bird flu after returning to Hong Kong from the Chinese mainland, and is in serious condition in a local hospital.

We just had H1N1 last year and this year we are going to have another round of flu, this time, H5N1.

Again, the worry is where did she contract the flu from? She must have got it from someone or from the birds.

And please, everyone, please practise cough/sneeze etiquette. Just imagine how H1N1 which started in Mexico could spread to the entire world. We should thank those who don't practise cough/sneeze etiquette for that.

As long as we don't observe this etiquette, we are going to face another round of influenza pandemic again.
