Swine Flu Facts

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.

SymptomsSwine 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.

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.
