Swine flu like viral strains are attacking the world from eons. But in the recent years it has emerged as an epidemic and has affected most parts of the world. The recent outbreaks of swine flu have forced health officials to declare it as an epidemic in the whole world. A disease is said to an epidemic if it occurs every year and affects masses present in that region. A disease is called pandemic if it appears rarely but affects all the continents within a short span of time.
Swine flu was common in pigs but in due course of time the H1N1 virus mutated and developed the ability to infect human body. It is also said that people living with pigs get infected with this virus and spread it to other people. It was assumed that the pork or pork product can increase the chances of infection from the swine flu virus, but research showed that the infected meat if cooked properly does not infect a person and people who did not eat pork made the larger fraction of swine flu sufferers. Swine flu spreads in the same manner as the common seasonal flu from person to person but grows very rapidly in the human body and cannot be recognized unless develops in the body. Whenever people hear swine flu as an epidemic in the whole world news, they become alert as this disease can make anyone its victim. Swine flu has also been declared as an epidemic because during the flu season anyone dealing with the symptoms of flu is considered as a swine flu patient unless he is not confirmed otherwise.
The truth behind swine flu as an epidemic in the whole world news
Due to over reporting the number of patients of swine flu hypothetically increases. It takes three days to confirm presense of H1N1 virus in a patient. In addition the vaccination given for the protection against swine flu has many side effects and it has also not proved to be fully efficient against flu. Swine flu epidemics started from Mexico in the year 2009 and spread in the most parts of the world. In USA almost every state reported at least one case of swine flu. Swine flu is an infectious respiratory disease which spread from the coughing and sneezing of an infected person. So when a person visits a place where cases of swine flu are prevalent or when a person comes to a place which is affected by H1N1, he becomes a potential carrier of swine flu virus. This way the virus first spreads from person to person, and slowly grips the whole world. Mostly the small children between six months to three years, young guys, pregnant women and people suffering form chronic diseases are attacked by the swine flu virus. So these are reasons of declaring swine flu as an epidemic in the whole world news.
