Deadly Swine Flu Outbreak Hits U.S. 2. Pigs May Be to Blame for Deadly Flu Outbreak 3. Scientists Tracing Origin of Deadly Swine Flu 4. More Deaths Reported in Swine Flu Outbreak 5. Second Wave of Swine Flu Hits U.S.

The deadly swine flu outbreak, which began in Mexico in April 2009 and has since spread to numerous other countries, reached the United States in early June. The first confirmed U.S. case was reported in California, and subsequent cases were discovered in Texas, New York and several other states. At least 21 people have died from the swine flu in the United States as of mid-June.

The cause of the swine flu outbreak is still unknown, but scientists are investigating how it originated. One theory is that pigs may be to blame; some experts believe that the strain of flu originated in pigs and then spread to humans. Pigs are known to carry a variety of flu strains, and this particular strain is believed to be a mix of human, pig and bird viruses.

The swine flu has proved to be more deadly than initially thought; as of mid-June, more than 460 people had died from it worldwide. In the United States, where there have been more than 2,000 confirmed cases, 21 people have died from the virus. Most of those who have died were young and healthy adults, which has alarmed public health officials.

A second wave of the swine flu has hit the United States in recent weeks; as of late June there had been more than 2,600 confirmed cases nationwide. This latest wave appears to be more severe than the first one, with a higher number of hospitalizations and deaths reported. Some areas of the country are being hit harder than others; for example, Texas has seen more cases than any other state.

Public health officials are urging people to get vaccinated against the swine flu if they haven't already done so. A vaccine is available now and is considered safe; it was used during the pandemic of 1957-58. There are also anti-viral drugs available that can help lessen the symptoms of swine flu if they are caught early enough.
