The report came as Mexico, the epicentre of the hither-to unknown influenza, started relaxing some of its restrictions and reduced its alert from red to orange. Restaurants, cafes, administrative offices and court buildings may re-open from Wednesday, provided that they respect certain health requirements.

In the US, a number of schools remained closed, under a 14-day shut-down guideline from US health officials.

Only Mexico and the US have reported any deaths. For Mexico, the death toll was 25, while for the US, it was one – a Mexican toddler who was treated and died at a Texas hospital.
