In the postpandemic period, which began on Aug. Preliminary genetic characterization found that the hemagglutinin HA gene was similar to that of swine flu viruses present in U.

The cause of the outbreak is still unknown and no exposure to pigs was identified. Will current vaccines work against swine flu.

Because of a striking similarity in the viral RNA of both strains — one which is unlikely to appear in nature due to antigenic drift — it was speculated that the later outbreak was due to a H1n1 influenza incident in Russia or Northern China, though this was denied by scientists in those countries.

Given the nature of international trade, the disease rapidly spread towards England, and reached the United States.

In October an intravenously administered antiviral known as peramivir, though not formally approved by the U.

The virus was passed from human to human primarily through inhalation of infectious particles or contact with an infected individual or a contaminated surface. The virus was suspected of having been carried to those states by individuals who had been in affected areas in Mexico and then traveled from there.

Although President Gerald Ford espoused the need for such a program, there was a consensus among many Congressmen that such a program was not warranted.

They did not recommend closing borders or restricting travel. The properties of RNA help to explain the epidemiology of influenza and the difficulty of achieving successful prophylactic treatment by using vaccines. Department of Health and Human Services had secured resources for the production of million doses of vaccine, expecting that the full stock would be available by mid-October.

The virus has been found in American hogs, [] and Canadian [] as well as in hogs in Northern Ireland, Argentina, and Norway. They also urged schools to suspend rules, such as penalties for late papers or missed classes or requirements for a doctor's note, to enforce "self-isolation" and prevent students from venturing out while ill; [] schools were advised to set aside a room for people developing flu-like symptoms while they waited to go home and to have ill students or staff and those caring for them use face masks.

The National Office of Vital Statistics in the United States recorded the distribution of deaths during showing that the highest levels of morbidity occurred at the extremes of infancy and old age, and was very low in between these two age groups.

As history would show, the predicted epidemic failed to materialize.

Influenza A virus subtype H1N1

By 19 Novemberdoses of vaccine had been administered in over 16 countries. Wash the hands and face regularly. In addition, many more cases of the disease were suspected in other countries, including Australia, Chile, Colombia, and France.

The H1N1 flu pandemic was the first influenza pandemic to be declared since the outbreak of Hong Kong flu, which caused more thandeaths. Can I eat pork meat and pork products?.

Swine flu is a disease of pigs that can, in rare cases, be passed to humans. It is a highly contagious respiratory disease caused by one of many Influenza A viruses. Information regarding the seasonal influenza vaccination can be found on the vaccination page.
