Rais Yatim said that it's difficult to pronounce H1N1 rather that "selsema babi" for reporters. So using the "selsema babi" will be easy for sending the message across. But anyway, it's good to find out the reason why it is called "swine flu" at first.
Why is novel H1N1 virus sometimes called “swine flu”?
This virus was originally referred to as “swine flu” because laboratory testing showed that many of the genes in this new virus were very similar to influenza viruses that normally occur in pigs in North America. But further study has shown that this new virus is very different from what normally circulates in North American pigs. It has two genes from flu viruses that normally circulate in pigs in Europe and Asia and avian genes and human genes. Scientists call this a "quadruple reassortant" virus.
