SWINE FLU OUTBREAKS

Like people, pigs can get influenza or medically termed as FLU but swine flu viruses are not the same as human flu viruses. Swine flu doesn't often infect people, and the rare human cases that have occurred in the past have mainly affected people who had direct contact with pigs. But the current swine flu outbreak is different. It's caused by a new swine flu virus that has changed in ways that allow it to spread from person to person -- and it's happening among people who haven't had any contact with pigs.

Others might say that Swine Flu can be typified as a respiratory disease, affecting pigs. According to World Health Organization, stating that a number of Swine Flu cases have resulted strain of H1N1 (conventional flu).
Scientifically, there are three types of viruses - A, B and C which causes influenza. Further each type has sub-types or strains, but each of the sub-type maintains the characteristic of the original virus.
Seasonal changes, especially setting of winter or ending of seasons, is a favorable time for the influenza viruses as they get active and spread among large populations.

Generally, people with strong immune system can easily recover from the effects of influenza as the body immune system fight against the viruses. With bird flu it is different as this virus strain (H5N1) makes the body produce large amounts of anti-bodies to the extent where it can kill the patient. A strong immune system will produce more antibodies than a weak immune system increasing the risk of death in healthy people.

On the other hand, Smoking can also make your immune system weak and the chance of having Swine Flu is big. Many viruses can be easily affected you and may suffer from it if not taking the right vitamins and minerals or any other protection which can help you free from this very well known disease.
