MEXICO CITY, May 29 (Xinhua) -- Mexico's health ministry on Friday updated the country's death toll from A/H1N1 flu to 97, two more than the Thursday figure, with the total number of infections reaching 5,029.

    The ministry again urged the public to wash their hands regularly and go to the doctors if they develop any flu symptoms, such as headaches, excessive mucus, muscular pain or breathing difficulties.

    The ministry said that the bulk of the newly confirmed cases are from old samples, and that from May 22 to the present only 10 people have been confirmed infected with the new virus. The peak of infections arrived on April 27, a week after the declaration of a national public health emergency, with 354 infections reported in a day.

    Mexico City remains the most infected region of the country, with 1,741 infections. The dead accounted for some 1.9 percent of those infected, and about one third of them had suffered from obesity or diabetes before they were sickened.

    The World Health Organization (WHO) said on Friday that there are now more than 15,500 infections across the globe, with the United States reporting the most infections in a single country. Only Mexico, the United States, Canada and Costa Rica have reported cases of flu-related deaths.
