Swine influenza is a respiratory illness that infects pigs. Caused by the influenza virus type A, there are regular outbreaks of swine herds in which the disease causes high rates of disease, but rarely fatal. Which tends to spread in the fall and winter, but throughout the year. There are many types of swine and human influenza, such as influenza, the infection is in constant evolution. Swine influenza does not usually infect humans, although sporadic cases occur, usually people who are in close contact with pigs. In addition, rare cases of documented infection to others. Transmission from person to person by the thought of swine influenza and seasonal influenza – by coughing and sneezing. The epidemic in Mexico seems to imply a new type of swine influenza, DNA, usually found in viruses from avian and human influenza.

The World Health Organization has confirmed at least some of the cases governed by this new strain of H1N1. “We are very, very worried,” World Health Organization (WHO), said spokesman Thomas Abraham. “We, leading to a new virus and has developed among the population … It was on deck all hands in time. ” Genetically quite different from human influenza virus H1N1 has been circulating around the world seasonal in recent years. , DNA, which is typical for poultry, swine and human viruses, including those in Europe and Asia the virus of swine When a new strain of avian flu acquires the ability to benefit from human to human, it is closely followed in this case has the potential to cause pandemics. WHO is worried, but said it was too early to assess the threat to call for a pandemic.

But he has a group of experts convened to an increase in supply or theme Travel opinion. Perhaps it is too late to trigger one of the leading experts on pandemic influenza United, “he says. Dr. Michael Österholm, an expert in the field of public health at the University of Minnesota, said that given the rapidity of the flu can spread around the world, if they are the first signs of a pandemic it is likely that the case in incubators and other parts of the world. “Literally, hundreds and thousands of passengers from Mexico every day,” said Österholm. “We must believe that it is more of the unknown, the transfer.” There is a vaccine to protect specifically against swine flu, and it is unclear how effective protection of human vaccines against influenza can.

However, the CDC, said that two anti-flu drugs Tamiflu and Relenza appears effective against the new strain. Roche, the manufacturer of Tamiflu, said the company is prepared to immediately deploy a reserve of medication, if necessary. Both drugs must be early in the days following the onset of symptoms to be effective. It is also feared that some forms of influenza have developed resistance to drugs. Scientists have long feared that a new influenza virus could be a global pandemic of a deadly disease.

A new pandemic influenza virus to develop when the different influenza viruses infect pigs, a person or a bird, mix their genetic material. The hybrid could be fast, because people do the natural defenses against them. The most famous of pandemic influenza are of the opinion, which killed at least 40 million people worldwide in 1918-19. Two other flu pandemics less deadly Struck in 1957 and 1968.
