Swine influenza – Swine influenza or swine flu is a respiratory disease in pigs caused by the type A H1N1 swine influenza virus (SIV). Humans in close proximity to swine could contract swine influenza if the swine are carrying the rare strain of the SIV that is capable of affecting humans.

Symptoms – Swine flu symptoms in humans are generally similar to regular flu (influenza) symptoms and include muscle pain, runny nose, sore throat, cough, headache, lack of appetite, fever, chills, and general weakness and discomfort. Other reported symptoms are nausea, vomiting and diarrhea.

Transmission – Swine flu spreads from pigs to humans when humans are close to infected pigs. People working in barns or visiting livestock exhibits housing infected pigs are likely to get affected. Transmission from humans to humans can occur when the infected individual coughs or sneezes when others are close by. Putting one’s hands to the nose or mouth after touching anything with the flu viruses on it could also spread the infection. Consuming well-cooked pork and pork products won’t cause infection as cooking to an internal temperature of 160°F kills bacteria and viruses, including the swine flu virus.

Treatment and medication – While swine flu can generally be cured by the four antiviral drugs approved for curing flu in the US, amantadine, rimantadine, oseltamivir and zanamivir, the recent 2009 swine flu outbreak viruses have been found to be resistant to the first two drugs. Oseltamivir and zanamivir are now recommended for treatment and prevention of swine influenza.

Prevention – Swine flu can be prevented by taking certain precautionary measures, such as washing hands frequently with soap or an alcohol-based hand wash. Staying away from infected individuals is important as their coughing or sneezing could spread the infection. If instances of infection are reported in your locality, stay indoors as far as possible. Swine flue vaccine could be out by June 2009.

Wash your hands

Basic way of preventing getting infected is washing your hands frequently, especially after coughing or sneezing. You can use soap and water, alcohol-based hand sanitizers are also effective. Hand sanitizers can be used when water isn’t available.

Don’t touch your eyes, nose or mouth

Germs spread when you touch your eyes, nose or mouth after touching something that’s contaminated.

Avoid close contact with sick people

If possible, avoid contact with possibly infected people. Avoid crowds. Swine flu spreads mainly when people cough or sneeze.

Avoid travel

Try to limit traveling, especially to high risk areas such as Mexico. If you’ve been to Mexico and have flu like symptoms visit a doctor.

Wear facemask or respirator

Centers for Disease Control and Prevention recommends wearing facemask in crowded settings to prevent getting infected and to not infect others. Respirator should be used if you have close contact with infected person (for example you’re caring of sick person at home).

Antiviral drugs

Swine influenza A (H1N1) is sensitive to Oseltamivir (sold under name Tamiflu) and Zanamivir (sold as Relenza). They are effective means of swine flu prevention and treatment. If taken for treatment, Tamiflu and Relenza are most effective if taken within 2 days after illness started. They are also effective for prevention if given to healthy person that had contact with infected people. Antiviral drugs are 70% to 90% effective means of flu prevention. According to CDC, number of days they should be used to prevent H1N1 influenza varies depending on each person’s situation.

Vaccine

Influenza A (H1N1) vaccine isn’t available yet, WHO and CDC are working on it.

Stay home if you feel sick

CDC recommends to stay at home for 7 days after symptoms begin or until you are symptom-free for 24 hours to not spread infection further.

Take care of your health

Sleep well, be active, manage stress, drink lots of fluids, eat healthy. This strengthens your immune system.

Survive the Pandemic Flu!

Eric Kampel asked:


The recent swine flu outbreak in Mexico has caused much trepidation among the international community, especially because of the increasing number of fatalities. It is important to recognize swine flu symptoms to prevent the spread of infection and illness.

Swine flu or swine influenza is a respiratory infection caused by the influenza type A virus, endemic in domestic pigs. In the past, swine flu has infected people only rarely – those infected being ones who have had direct and close contact to infected pigs. But the current swine flu outbreak in Mexico is different, caused by a new strain of the swine flu virus. As per recent health reports, swine flu is being transmitted with surprising speed in humans, spreading easily from person to person, causing serious illness among those infected. It has been reported that the disease has been diagnosed in humans who haven’t had any exposure to pigs.

Among pigs, swine flu symptoms include sudden onset of fever, depression, coughing, sneezing, breathing difficulties, redness or inflammation of the eye, going off feed, and discharge from the nose or eyes.

Like the influenza virus affecting humans, swine flu viruses are constantly mutating. Although the swine flu viruses are not the same as human flu viruses, swine flu symptoms resemble those produced by regular human seasonal influenza. In humans, common swine flu symptoms are fever, chills, sore throat, muscle pain, severe headache, coughing, lethargy, lack of appetite, weakness, and general discomfort. Some may even experience runny or stuffy nose, nausea, vomiting and diarrhea.

However in humans, self care measures and appropriate treatment in the early stages of infection can reduce the increased risk of these complications. In order to confirm that the illness is the result of a swine flu virus, one must undergo laboratory testing. Antiviral drugs such as Tamiflu and Relenza are considered effective for the treatment and/or prevention of infection by swine flu viruses.

Swine flu or swine influenza is a disease common in swine, with normal flu-like symptoms, but caused by any strain of the swine influenza virus (SIV – virus endemic in pigs). Though rare in humans, individuals with greater exposure to swine could contract swine influenza if the swine are carrying the particular rare strain of the SIV that is capable of affecting humans. Even then, it is a rare occurrence for the strain to be able to pass from human to human. This could occur if the SIV is able to mutate into a form that can be easily transmitted among humans.

The swine flu outbreak of 2009 is believed to be caused by such a mutated strain of the SIV. The current outbreak is called swine flu only because one of the surface proteins of the tested virus is similar to the one which infects pigs. It is still unknown if this is currently infecting pigs though it’s clearly spreading among people, leading the World Health Organization to raise the Phase 4 pandemic alert. This new strain responsible for the outbreak has been found to be a re-assortment of strains of the influenza A virus subtype H1N1. These strains are separately endemic in humans and in swine.

According to the Centers for Disease Control and Prevention (CDC), Tamiflu (oseltamivir) and Relenza (zanamivir) would help in treatment and prevention. Antiviral drugs, if started within two days of the manifestation of symptoms, succeed in reducing the severity of the symptoms, preventing further complications, and hastening cure. The most effective method of prevention is to wash hands frequently with soap or with a foam or alcohol-based gel hand wash that helps wipe away bacteria and viruses. Vaccines against the 2009 H1N1 strain outbreak are in the development stage and are expected to be ready by June 2009.
