Swine Influenza Symptoms - #6992

I recently heard about Swine Influenza (Swine Flu), and I realized I don’t fully understand how it affects people. I know it comes from pigs, but what exactly are the Swine Influenza Symptoms, and how is it different from regular flu?? From what I read, Swine Influenza (H1N1 flu) is a strain of the influenza virus that originally spread among pigs but can also infect humans. But how does someone catch Swine Influenza—is it only from direct contact with pigs, or does it spread between humans too?? I also saw that Swine Influenza Symptoms are similar to regular flu, including fever, cough, sore throat, body aches, and fatigue. But are there any specific symptoms that make Swine Flu different? Does it cause more severe respiratory issues or complications like pneumonia?? One thing that really worries me—how dangerous is Swine Influenza? I read that the 2009 H1N1 pandemic was caused by this virus, but is it still a major threat today? And is there a vaccine that protects against it?? For those who have had Swine Influenza, what were your symptoms like? How long did it take to recover, and did you need any special treatments??
