Swine flu
Swine flu — Comprehensive overview covers swine flu symptoms, tests, treatment and prevention.
Definition
Swine flu refers to a respiratory infection caused by influenza A viruses that ordinarily cause illness in pigs. Humans can catch swine flu from infected pigs, but pig-to-human transmission is unusual. Human-to-human transmission of true swine flu is also possible but infrequent.
The recent outbreak of what is being called swine flu involves a new H1N1 type A influenza strain that’s a genetic combination of swine, avian and human influenza viruses. It’s capable of spreading from human to human.
In June 2009, based on its wide spread to many nations, the World Health Organization declared the swine flu outbreak a global pandemic.
This new swine flu strain is being called by a number of names, including: swine-origin influenza A, swine influenza A (H1N1), influenza A/California/H1N1, swine origin influenza virus, North American flu and influenza A (H1N1).
The best approach you can take is to try to avoid infection. If you do develop symptoms of swine flu, seek prompt medical attention so that you have the best chance of antiviral drugs providing you with successful treatment.

Swine Flu Treatment
In swine
As swine influenza is rarely fatal to pigs, little treatment beyond rest and supportive care is required. Instead veterinary efforts are focused on preventing the spread of the virus throughout the farm, or to other farms.Vaccination and animal management techniques are most important in these efforts. Antibiotics are also used to treat this disease, which although they have no effect against the influenza virus, do help prevent bacterial pneumonia and other secondary infections in influenza-weakened herds.
In humans
If a person becomes sick with swine flu, antiviral drugs can make the illness milder and make the patient feel better faster. They may also prevent serious flu complications. For treatment, antiviral drugs work best if started soon after getting sick (within 2 days of symptoms). Beside antivirals, supportive care at home or in hospital, focuses on controlling fevers, relieving pain and maintaining fluid balance, as well as identifying and treating any secondary infections or other medical problems. The U.S. Centers for Disease Control and Prevention recommends the use of Tamiflu (oseltamivir) or Relenza (zanamivir) for the treatment and/or prevention of infection with swine influenza viruses; however, the majority of people infected with the virus make a full recovery without requiring medical attention or antiviral drugs. The virus isolates in the 2009 outbreak have been found resistant to amantadine and rimantadine. Read more
