As of April 29, 91 people in the United States had confirmed cases, according to the US Centres for Disease Control and Prevention (CDC). The first US death occurred on April 27, when a two-year-old child succumbed to swine flu after travelling from Mexico to Houston for treatment.

At least three cruise lines have suspended stops as of this week at Mexican ports because of concerns over the country's swine-flu outbreak. The cancellation of ship visits followed a recommendation issued this week by the U.S. Centres for Disease Control that advised US citizens to avoid non-essential travel to Mexico.

United States health officials said Wednesday that a vaccine against the H1N1 virus, also known as the swine flu, could be ready for human use by early September. The announcement was made at a joint press conference held by the Department of Health and Human Services, the Centers for Disease Control, and the Food and Drug Administration.

Mexico has long been considered the laboratory of globalization. Now a potentially deadly virus has germinated in that laboratory, finding ideal conditions to move quickly along a path toward global pandemic.

The deadly swine flu virus could infect up to 40% of the United Kingdom population in the next six months if the outbreak becomes a pandemic, world health officials said. Professor Neil Ferguson, a member of the World Health Organisation (WHO) taskforce which decided to raise its alert over the virus to level four, said four in 10 people could be infected if the country is hit by a pandemic.

The World Health Organization (WHO) has raised its alert level over swine flu from three to four, two steps short of declaring a full pandemic. WHO Assistant Director General Dr Keiji Fukuda said it signalled a significant step towards pandemic influenza, but added we are not there yet.

The international community is better prepared than ever to deal with the threatened spread of a new swine flu virus, the top United Nations health chief has said. As the UN warned the outbreak might become a pandemic, World Health Organization Director-General Dr Keiji Fukuda said years of preparing for bird flu had boosted world stocks of anti-virals.

Health experts in Britain are on high alert to prevent the spread of a new human strain of the swine flu virus. Britain’s NHS also revealed it has a stockpile of £ 500 million of Tamiflu anti-viral drug which has proved effective on patients in Mexico where the outbreak seems to have started.

Mexican Public Health Secretary Jose Angel Cordova said on Sunday that the number of deaths from swine flu virus had increased to 103, with 1.614 suspect cases and 400 in hospitals. Meantime in neighbouring United States the Health and Human Services, HHS, issued a nationwide public health emergency declaration.

Paraguay’s president Fernando Lugo and the Pan-American Health Organization, PHO, launched Sunday a new edition of the “Vaccination in the Americas” week which has the purpose of vaccinating 30 million people against a wide range of diseases that still ravage the region.
