Tamiflu-resistant swine flu which has broken out in Wales will become much more common as the virus mutates, a flu expert said.
Three out of five patients diagnosed with the Tamiflu-resistant strain remain in hospital, after it was revealed they could be the world's first cases of person-to-person transmission of the virus, the National Public Health Service for Wales (NPHS) said.
Professor Nigel Dimmock, a virologist at the University of Warwick said: "This is just the beginning. You have got a lot of viruses and if you use Tamiflu at the level they are using it you get resistance.
"However, they probably aren't resistant to Relenza, the other antiviral. You need other mutations to make it resistant to Relenza.
"Also, the vaccine is coming on so people regard Tamiflu as a stop gap and there's no need to panic."
