    What is swine flu?


    Swine flu is a highly contagious respiratory disease in pigs. The disease is caused by a virus and causes sickness in the animals, but has a low death rate. The virus frequently circulates among the animals throughout the year, with outbreaks more common in the fall and winter.

    How do people become infected?

    The CDC says the spread of swine flu can occur in two ways: through contact with infected pigs or environments contaminated with the virus; or through contact with a person with swine flu. The CDC has determined that the virus is contagious and spreading among people, but at this time it is not known how easily that happens.

    Is this a pandemic?


     


    No, not yet, at least. But it is considered an outbreak, or a sudden increase in the numbers of a particular illness. What caused doctors in Mexico to sit up and take notice was a sudden jump in serious pneumonias at the end of the regular flu season. Tests are under way now to determine how many of these cases might be swine flu.

    A pandemic is a worldwide outbreak of disease, typically affecting millions of people. An epidemic is a disease that spreads rapidly and widely in a localized region or country. And since officials aren't sure how many of the cases are actually swine flu, it's still too early to call it an epidemic.

    The World Health Organization, one of the groups monitoring the situation and coordinating an international response to the swine flu outbreak, currently has the situation listed as "Phase 3," on a six-step scale, which means that though the disease has affected small clusters of people, the swine flu "has not resulted in human-to-human transmission sufficient to sustain community-level outbreaks."

    WHO officials have called the outbreak a "public health emergency of international concern," but have so far held off raising the pandemic level any higher. Phases 4 and higher represent significant human-to-human spread of the virus both at a community level and worldwide.

    If this isn't yet a pandemic, why the alarm?

    Officials don't yet know how contagious the disease is or exactly how it's spreading, but the high number of cases as well as the geographic distribution has them on the lookout for more cases, which are expected to be found. Influenza viruses, like the swine flu, can be transmitted between people by coughing or sneezing, or by touching something with a flu virus on it.

    Here is more information on Swine Flu:

    What are the symptoms?

    The symptoms are similar to those of regular flu:
    - Fever
    - Lethargy
    - Runny nose
    - Cough
    - Sore throat
    - Lack of appetite
    - Vomiting and diarrhoea in some cases.

    How common is swine flu infection in humans?

    In the past reports of about one human swine flu virus infection had been received every one to two years in the United States. From December 2005 till February 2009, 12 cases have been reported.

    Has this strain of flu been seen before?

    No. Flu mutates constantly, so it is common for new strains to emerge. Pigs can also be infected with both human and avian influenza, and the current circulating swine flu strain appears to contain genetic elements from all three.

    Can swine flu be treated with antiviral drugs and flu vaccine?

    The swine flu is resistant to two common drugs – Amantadine and Rimantadine. The H1N1 swine flu viruses are very different from human H1N1 viruses. Therefore, vaccines for human seasonal flu would not provide protection. However, a “seed vaccine” has been specifically tailored to this swine flu and will be manufactured if officials deem it necessary.

    Can people catch swine flu by eating pork?

    No. Swine influenza viruses are not transmitted by food. Eating properly handled and cooked pork and pork products is safe. Cooking pork to an internal temperature of 70ºC and above kills the swine flu virus.

    How long is someone with swine flu considered contagious?

    People with swine influenza virus infection should be considered potentially contagious as long as they are symptomatic; possibly for up to seven days following the onset of the illness. Children, especially younger children, might potentially be contagious for longer periods.

    What can I do to protect myself from the swine flu?

    There is no vaccine available right now to protect against the swine flu.

    However, you can help prevent the spread of germs that cause respiratory illnesses like influenza by:

    - Covering your nose and mouth with a disposable tissue or handkerchief when you cough or sneeze. Throw the tissue in the waste basket after you use it.

    - Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also helpful

    - Try to avoid close contact with sick people. - If you get sick with influenza, stay at home and limit contact with others to keep from infecting them.

    - Avoid touching your eyes, nose or mouth.

    - Consult your nearest healthcare facility if you think you have any of the symptoms.

    Which countries have had cases of the swine flu?

    The World Health Organisation (WHO) has confirmed human cases of swine flu in Mexico, the United States, Canada and Spain. Only Mexico has reported deaths from the new strain.

    CDC recommends the use of oseltamivir or zanamivir for the treatment and/or prevention of infection with swine influenza viruses.


    1. Oseltamivir (brand name Tamiflu ®) is approved to both treat and prevent influenza A and B virus infection in people one year of age and older.

    2. Zanamivir (brand name Relenza ®) is approved to treat influenza A and B virus infection in people 7 years and older and to prevent influenza A and B virus infection in people 5 years and older.

    Recommendations for using antiviral drugs for treatment or prevention of swine influenza will change as we learn more about this new virus.
