Whatever happened to bird flu?
Strains of avian influenza, or bird flu, are still around, these viruses exist in host species in Asia and potentially elsewhere and could still make the leap to humans at any time. Alternatively, another host species harbouring a different type of virus altogether might emerge at another time.
Will there be a global flu epidemic?
“We do not know whether this swine flu virus or some other influenza virus will lead to the next pandemic,” says, Richard Besser, acting director of the CDC, “However, scientists around the world continue to monitor the virus and take its threat seriously.” UPDATE: the WHO raised its alert level from Phase IV to V, with recent infection rates in Japan, the WHO has been hinting that they will need to upgrade to pandemic Phase VI.
How can we prevent the spread of swine flu?
People at risk should cover their mouth when they cough. They should regularly wash their hands with an alcohol-based cleaner and and avoid close contact with the sick. Patients with the disease should stay at home. There is no need to avoid eating pork.
Has the disease spread to the USA?
Cases in California, Texas, and Kansas, have been confirmed and tests are being carried out on students at a school in New York. Cases have been seen in New Zealand, Spain, Scotland, and elsewhere; those infected have been recovering well.
Swine Flue H1N1
World Health Organisation took us to Phase 6 on June 11, which only means that they see the distribution of the virus across the globe as being at levels associated with a flu pandemic, the first such declaration since 1968. The virus itself has not become any worse nor have the chances of any individual dying from the disease increased.
Swine flu is still with us although the media hype has died down. There have been numerous cases and many deaths, but nothing on the scale of the millions predicted early on. Could this first wave strain now be evolving into a more virulent form that will affect the northern hemisphere more severely after the summer is over?
I’ve previously discussed the many latent diseases in hosts as rodents, birds, and cattle. Many of these are ready and willing to make the species leap to humans given the opportunity. For the last ten years or so bird flu and Asia have been the focus of much research and concern. However, the wave of swine flu (H1N1) infections that began in March-April 2009 in Mexico highlight the fact that a potentially lethal strain of virus can emerge from other species and not necessarily in Asia.
Currently, not all the deaths attributed to swine flu have been definitively associated with type A H1N1 influenza, the actual mortality rate could be as low as 1% or as high as 6.5% depending on how you count.

What is swine flu?
Swine flu, normally seen in pigs caused by Type A influenza viruses are known as a respiratory disease and that disease can spread rapidly.
People get in to?
From pig and human flu from human to pigs to humans can be infected. People do not have natural immunity against viruses.
Therefore, the World Health Organization (WHO), to leave the control of disease outbreaks which can be broadly found in the alert.
Influenza is captured in the Mı eat pork?
Swine flu virus in pigs infected with the flesh is not the defeated. The virus is spread by breathing.
Pigs in this new type of flu?
Such as human influenza virus, swine influenza virus in pigs also shows continuous change. Pigs in the respiratory tract of pig, human and bird flu viruses are sensitive to the recipient.
Therefore, pigs, infected with viruses simultaneously in the case of the emergence of new influenza viruses is increasing the likelihood.
DSÖ'ye, the cause of death in Mexico of the swine influenza A/H1N1 virus. This virus can infect human to human. A/H1N1 virus, human, pig and is made of a mixture of bird flu virus.
Do vaccine?
The vaccine is available to the pigs, but no human vaccine yet.

Swine influenza
Swine influenza (also called swine flu, hog flu, pig flu and sometimes, the swine) is an infection by any one of several types of swine influenza virus. Swine influenza virus (SIV) is any strain of the influenza family of viruses that is endemic in pigs.[2] As of 2009, the known SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H3N1, H3N2, and H2N3.
Swine influenza virus is common throughout pig populations worldwide. Transmission of the virus from pigs to humans is not common and does not always lead to human influenza, often resulting only in the production of antibodies in the blood. If transmission does cause human influenza, it is called zoonotic swine flu. People with regular exposure to pigs are at increased risk of swine flu infection. The meat of an infected animal poses no risk of infection when properly cooked.
During the mid-20th century, identification of influenza subtypes became possible, allowing accurate diagnosis of transmission to humans. Since then, only 50 such transmissions have been confirmed. These strains of swine flu rarely pass from human to human. Symptoms of zoonotic swine flu in humans are similar to those of influenza and of influenza-like illness in general, namely chills, fever, sore throat, muscle pains, severe headache, coughing, weakness and general discomfort.
