The Rise Of Swine Flu And How It Spreads The Centre of Disease Control and Prevention explains that swine flu is a highly contagious breathing illness that affect pigs. While it's uncommon for humans to catch swine flu from pigs, it can happen if they are in close contact with infected pigs or places where their viruses are present. Once a person gets infected, they can then spread the virus to other people, likely through coughing or sneezing, just like regular seasonal flu. How Swine Flu Changes CDC explains that just like the flu virus that affects people and birds, swine flu viruses are always changing. Pigs are unique because they can catch flu viruses not just from other pigs, but also from birds (avian flu) and people (human flu). When different types of flu viruses infect a pig at the same time, they can mix and swap their genetic material. This is like shuffling a deck of cards. When they mix, brand new flu viruses can be created that are a combination of swine, human, or avian flu. Over time, many different kinds of swine flu have appeared. Right now, in the United States, there are three main types of influenza A viruses found in pigs: H1N1, H1N2, and H3N2. Treating H1N1 – Managing the Disease According to Medscape, if you have H1N1 flu, the main goal of treatment is to help you feel better. This usually means resting a lot, drinking plenty of fluids, and taking medicines to calm your cough, lower your fever, and ease muscle aches (like Tylenol or ibuprofen). If someone gets very sick, they might need fluids given through a vein and other help from doctors. Sometimes, doctors might also give special antiviral medicines to treat the flu or to keep you from getting it if you've been exposed.
