The swine flu is influenza which is in news these days and becomes headlines when a VIP or popular personality gets caught by it. In this article, we will tell you about this flu and how people get infected by it and also about its symptoms?

Swine flu is the name for the influenza type A virus that affects pigs (swine). Although swine flu doesn’t typically affect humans, there was a global outbreak (pandemic) in 2009–2010, the first flu pandemic in more than 40 years. It was caused by a then-new flu virus known as H1N1, a type A influenza virus that’s a combination of swine, avian (bird), and human genes that mixed together in pigs and spread to humans. H1N1 is now considered a normal type of seasonal flu and is included in the flu vaccine. The Centers for Disease Control and Prevention (CDC) estimates that swine flu infected nearly 61 million people in the United States and caused 12,469 deaths. Worldwide, up to 575,400 people died from pandemic swine flu.  

H1N1 causes a respiratory illness and is very contagious. Symptoms  are similar to those of the seasonal flue  and may include: 

  • Fever 
  • Body aches 
  • Loss of appetite 
  • A cough 
  • A sore throat 
  • A headache 
  • Fatigue 
  • A runny nose 
  • Irritated eyes 
  • Vomiting, nausea, and diarrhea 

H1N1 flu is also known as swine flu. It’s called swine flu because, in the past, the people who caught it had direct contact with pigs. That changed several years ago, when a new virus emerged that spread among people who hadn’t been near pigs. 

In 2009, H1N1 was spreading fast around the world, so the World Health Organization called it a pandemic. Since then, people have continued to get sick from swine flu, but not as many. People who have swing flu can spread it one day before they have any symptoms and as many as seven days after they get sick. Kids can be contagious for as long as 10 days.
