in 1918-1919, swine flu was killed tens of millions of people. In 1967 was just a scare. Nothing serious actually. Now? Critical level! Where is it's origins you ask, in mexico. Where is the REAL ORIGINS you ask, I don't know. Possibly from animals, human designed for money, number of dead disease, i don't know. All I know is this, the disease has spread to US for sure. Now it hits Europe, and Thailand. MY GOD, THAILAND! Near our area. Other areas? I didn't check. Anyhow, more news about swine flu will be updated later.
PS, hope you are lucky enough that your school call of a 1 week holifay.
