Influenza A virus subtype H1N1, also known as A(H1N1), is a subtype of influenzavirus A and the most common cause of influenza (flu) in humans. Some strains of H1N1 are endemic in humans.Influenza A virus strains are categorized according to two proteins found on the surface of the virus: hemagglutinin (H) and neuraminidase (N). All influenza A viruses contain hemagglutinin and neuraminidase, but the structure of these proteins differs from strain to strain due to rapid genetic mutation in the viral genome.
Influenza A virus strains are assigned an H number and an N number based on which forms of these two proteins the strain contains. There are 16 H and 9 N subtypes known in birds, but only H 1, 2 and 3, and N 1 and 2 are commonly found in humans.
As far as I know, there are 144 different combinations that a flu can mutate into. China,Hong Kong,South Korea and Malaysia.
Many countries are doing the screening at the airport,all schools are doing the temperature taking,many shopping centers are providing hand sanitisers to clean their hands. I don't think that it is effective as the symtoms take 7 days to take shape so by the time it has already sperad to many people.
Singapore advised public to take precautionary measures such as avoiding crowded areas and maintaining high standards of personal hygiene at all times. However, if you are unwell with fever and cough but have no travel history to affected areas, please see a doctor and stay at home.
I will follow the government's advice to maintain high standards of personal hygiene and see a doctor if I've a cough or fever.

Kindness
Kindness is an ongoing act. Kindness is happening everywhere. This is the message from our government. In his 1996 New Year Message, then Prime Minister Goh Chok Tong highlighted the need for Singapore to become a gracious society by the 21st century.
Kindness start from ourselves, we must pass it on to our family members, friends and relatives. Kindness is helping somebody who is in need of help. Is the practice of being or the tendency to be sympathetic and compassionate. Yes, it is important for people to be kind as if you help someone, in the future,when you need help,that person may help you. People can show their kindness by helping others or just helping something (go to http://www.helpothers.org/story.php). One day after school, I took the bus back home, I saw an old lady climbing up the stairs boarding the bus. I decided to offer my seat to the old lady. Unfortunately, a young man sat down on the seat instead of the old lady. Doesn't that make you angry? Well,I was pretty angry and did not want to make a scene as another boy offered his seat to the old lady. With these people around, I think Singapore will take many more years to become a gracious or kind society.

SA1 Oral Exam
Hi,I am back after the long preparation for SA1. I think Mrs Azhar will be mad at me as I am quite far back in updating my blog. I am going to post about my over due SA1 Oral Exam. I had my oral exam on 22nd April Wednesday. Actually it was supposed to be on Thursday but because of Maths Olympiad, Miss Rahimah had to change the date of our Oral Exam.
That day,after lunch,we lined up in the hall to be tested on oral. At first,I thought the examiner was Mrs Subra but it was Mr Muzaffar. While i was waiting, I did my homework. The picture was a bus stop with students littering, playing soccer and dashing across the road.I remembered to look into the teacher's eyes. The most difficiult part was the picture conservation. Mr Muz asked "Have you ever witnessed a accident?"I replied "No". I think that I did not do well as I mumbled a few words. I think that he was a bit angry with me. Let's hope I do well.
Next was Chinese. I had to wait for my turn be called. Then, the teacher called about ten of us to the corridor of the hall to wait for our turn. (Shawn was in front of me). We were taken to the space beside the spiral staircase which was where we sit and prepare to read the passage and describe the picture. My chinese teacher,Mr Koo,tested me for oral. The passage was difficult as I did not know most of the words. I have to pray that I pass my chinese.
Hope everyone in my class P6.6 strive hard for good result!!!GOOD LUCK!!!
