The study by researchers at London's Imperial College, published in the journal Science, found that swine flu has "full pandemic potential", spreading easily from person to person and infecting around one in three of those who come into contact with it.
Swine flu is certainly milder than the Spanish flu which caused an estimated 50 million deaths in 1918, but it is not yet possible to say whether it will kill more than the most recent pandemics in 1957 and 1968.
The number of laboratory-confirmed cases of the swine flu or A(H1N1) virus has increased to 4,694 - double from the last Friday's figure - and also claimed 53 lives around the world, the World Health Organization (WHO) has said.
If it hits my lovely country India, am not sure what will be the outcome. I know that the government agencies here are so prompt & efficient, it will cause at least a million deaths before its wiped out of India. So I pray for the well being of my fellow citizens.
