What is the difference between regular flu and swine flu?

Other than the fact that it is spread by pigs rather than humans.

Are the symptoms any different?

There are different strains of flu, including different strains of swine flu. This particular swine flu is different because it has so little genetic relationship with the flus we have experienced in recent decades. Our immune systems have never been exposed to it or anything similar, so we lack resistance to it. Also, it is readily contagious from human to human (like most of the flus we suffer from). And it strikes those with the most robust health the hardest. It kills people in their prime instead of killing the weak.
The reason it kills the strong, I assume, is that it produces an excessive immune reaction, and people die from the immune reaction rather than from the virus itself. This is what happened in 1918, but that was an avian flu.

What are the symptoms of swine flu in humans?
The symptoms of swine flu in people are expected to be similar to the symptoms of regular human seasonal influenza and include fever, lethargy, lack of appetite and coughing. Some people with swine flu also have reported runny nose, sore throat, nausea, vomiting and diarrhea.

How can human infections with swine influenza be diagnosed?
To diagnose swine influenza A infection, a respiratory specimen would generally need to be collected within the first 4 to 5 days of illness (when an infected person is most likely to be shedding virus). However, some persons, especially children, may shed virus for 10 days or longer. Identification as a swine flu influenza A virus requires sending the specimen to CDC for laboratory testing.

omg..i just looked this up today..my son is sick..i got a lil freaked out when my sister told me she saw on the news that someone from Mexico stole the virus to release in U.S.

(CNN) -- A potentially deadly new strain of the swine flu virus cropped up in more places in the United States and Mexico on Saturday, in what the World Health Organization called "a public health emergency of international concern."

Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza virus that regularly causes outbreaks of influenza in pigs. Swine flu viruses cause high levels of illness and low death rates in pigs. Swine influenza viruses may circulate among swine throughout the year, but most outbreaks occur during the late fall and winter months similar to outbreaks in humans. The classical swine flu virus (an influenza type A H1N1 virus) was first isolated from a pig in 1930.

The regular flu is composed of different genetic types than the swine flu. The so-called swine flu is actually now known to be made up of human, avian and swine flu viruses that have recombined into a new strain.

There are hundreds of different strains of the influinza virus, however they are all made of RNA For a very simple answer, its a slight difference in the negative-sense RNA genome that mutates in the host over time.

Swine flu can bind with human flu. This present flu is a combo of human, pig, and bird flus. Don't let any "expert" tell you that it is a natural combo. This one was hatched out in a laboratory by humans for some purpose.

Where it comes from

If men stop having sex with pigs,we would not enduring this swine flu.[truth to be known.a pigs virgina,is as close to a womens,in the animal kingdom].That is a true fact,so guys put it elss where.Cheers lol.
