Swine flu is caused by the H1N1 virus. It is a respiratory disease which can be life-threatening.  Earlier this influenza virus was not found in people. It normally occurs in pigs but now it also infects humans. This influenza virus of type A was found the first time in humans in Mexico during 2009. Scientists found that this virus was originated in pigs. Swine flu was found in pigs in the 4 states of the United States in 1998. The swine flu pandemic killed almost 2, 00000(2lakhs) people worldwide in 2009. It was termed pandemic because it has the capacity to spread very fast across the globe.


Like other seasonal flu or fever, it is also contagious and the virus is transmitted from one affected person to another healthy person. The droplets coming out from coughing and sneezing contain H1N1 virus. The virus is transmitted when a person comes in contact with infected air. The lifetime of H1N1 influenza virus is just a few minutes therefore even if healthy people with strong immunity power come in contact, they may not catch the virus.


H1N1 influenza can infect cells deeper in the lungs than a seasonal strain of H1N1. The seasonal viruses attach themselves with receptors found on the outside of the cells. The seasonal influenza viruses are attached to cells found in the nose, throat and respiratory tract. The severe H1N1 virus can also attach to receptors of the cells found deep inside the lungs. The viruses are multiplied many thousands of times within the cell. Therefore pandemic H1N1 can cause acute respiratory disorders and be fatal. They replicate rapidly and can infect more neighboring cells of the respiratory tract, causing serious lung diseases.


Following are the frequently asked questions (FAQ) about swine flu symptoms, warning signs, causes, and treatment.

The serious infection can do more harm to the lungs than seasonal flu. The cold or normal flu cannot attach to cells while the H1N1 virus produces more viruses by using cell machinery. Without laboratory tests, it is hard to distinguish between the two diseases.

What is swine flu treatment?

Most of the people recover within 7-8 days but it is recommended that people who are suspected or infected should be treated with antiviral medicines. The antiviral agents prevent and reduce the severity of the H1N1 flu. The medicines used for treatment are Oseltamivir(Tamiflu) and Zanamivir. These drugs are more effective when they are given within 2 days of infection. The swine virus is also resistant to drugs like Amantadine and Rimantadine. People with serious symptoms should be treated in the intensive care unit. It is preventable by the H1N1 vaccine.
