Swine flu will not cause a pandemic this winter, and it won't mutate into a terrible superbug, despite what our health officials and the World Health Organization tell us.
Even so, swine flu will be easy to catch, say researchers from the University of Maryland, who have carried out tests on three different viruses, including the H1N1 responsible for swine flu.
The H1N1 virus doesn't interact with other viruses and won't cause a superbug, says virologist Daniel Perez. But because it's a new virus, it's very infectious and people haven't yet been able to build a natural immunity against it.
