The good times just keep rolling..

• new strain of flu
• has the potential to become pandemic
• emerged recently and is carried by pigs, but can infect humans
• researchers are concerned that it could mutate further so that it can spread easily from person to person, and trigger a global outbreak
• say it has "all the hallmarks" of being highly adapted to infect humans
• as it's new, people could have little or no immunity to the virus
