Mexico's deadly swine flu outbreak is raising fears that the virulent disease could spread and create a global pandemic.
Spain became the first country outside North America to report its first case and was soon followed by two confirmed cases in Scotland on Monday. Canada and certain states in the U.S are the other areas where cases of the disease have been confirmed.
The suspected death toll from swine flu in Mexico had increased to 149 since Monday. The Mexican Health Ministry had reported that 20 cases are confirmed as swine flu, according to the BBC News .
The swine flu scare has disrupted travel plans to Mexico by people around the world. In Asia, health authorities have taken steps to screen in-coming passengers at airports.
The BBC News website reported that Mexico's Health Minister Jose Angel Cordova said nearly 2,000 people had been hospitalised since the first case of swine flu was reported on April 13.
