Swine flu has now infected 13,398 people in 48 countries since it was first uncovered last month, the World Health Organisation said today.
The number of deaths rose to 95 after three more deaths were reported by Mexico, while the total caseload grew up 444 from one day ago, according to the WHO's daily tally of confirmed cases.
The bulk of the new cases were posted by Mexico, with 367 additional cases, bringing its total to 4,541.
Other significant rises were recorded in Australia, with 20 new cases leading to a total of 39, and Argentina, which posted 14 new cases and a total caseload of 19.
Bahrain and Singapore both reported infections to the WHO for the first time. One case was recorded in each of the two countries.
Some affected countries no longer keep track of all cases according to the WHO, while others do not report daily.
WHO interim Assistant Director General Keiji Fukuda said Tuesday that the outbreak was continuing to evolve.
"I think it's quite possible that it will continue to spread and it will establish itself in many other countries in multiple regions, at which time I think it would be fair to call it a pandemic at that point," Fukuda said.
