Scientists have found a superbug that is resistant to most antibiotics. So far it is widespread in India, and it could soon appear worldwide. In the journal, Lancet Infectious Diseases, doctors reported finding a new gene, NDM-1, which alters bacteria, making it resistant to nearly all known antibiotics. This is a particular risk for people on "health tourism" trips seeking cheaper medical care in India and Pakistan.
The BBC's Johnny Hogg reports on the difference between this new but and MRSA and what makes it so dangerous.
