What is Swine flu:
Swine flu or influenza is influenza caused by any strain of the influenza virus endemic in pigs (swine). Strains endemic in swine are called swine influenza virus (SIV). It is caused by a type-A influenza virus. Outbreaks in pigs occur year-round. The most common version is H1N1. The current strain is a new variation of an H1N1 virus, which is a mix of human and animal versions.
Symptoms of swine flu:
The symptoms are similar to the common flu. They include fever, lethargy, lack of appetite, coughing, runny nose, sore throat, nausea, vomiting and diarrhea.
Swine flu in world:
Swine flu is common in swine in the midwestern United States, Mexico, Canada, South America, Europe, Kenya, China, Japan, Taiwan, and other parts of eastern Asia.
How Swine flu Spread:
Caused by influenza type A virus, there are regular outbreaks among herds of pigs, where the disease causes high levels of illness but is rarely fatal. It tends to spread in autumn and winter but can circulate all year round. There are many different types of swine flu and like human flu, the infection is constantly changing. Swine flu does not normally infect humans, although sporadic cases do occur usually in people who have had close contact with pigs. There have also been rare documented cases of humans passing the infection to other humans.
Death from Flu:
The most notorious flu pandemic is thought to have killed at least 40 million people worldwide in 1918-19. Two other, less deadly flu pandemics struck in 1957 and 1968.
