H1N1 Flu Causes: Facts and Myths

We all know the H1N1 flu causes people to have influenza-like symptoms. We also know that it is currently considered a pandemic by the World Health Organization (WHO). Protecting yourself and your family from this new flu strain is vital for your safety. But have you wondered what causes the H1N1 flu?

H1N1 Flu Causes: What Causes It?

The H1N1 flu is caused by coming into contact with a complex virus called the H1N1 virus.

The H1N1 virus, more commonly known as the swine flu virus, is a virus subtype responsible for influenza. This new strain, discovered in 2009, is genetically more complex than other strains. According to WebMD.com, it is made up of four previous influenza strains-the North American swine influenza strain, the North American avian influenza strain, the human influenza strain, and the Asian-European swine influenza strain.

Despite its complexity, it infects humans in roughly the same manner as the regular influenza strain. When an infected person sneezes or coughs, they release microscopic droplets containing the H1N1 virus, which can land on a variety of surfaces-door knobs, desks, and even clothes or bedding. When a healthy person touches the contaminated surface, the virus enters their body and begins attacking healthy cells, which causes H1N1 influenza. Symptoms typically appear after a few days. This is how it mainly infects otherwise healthy individuals.

Debunking Myths Surrounding Its Causes

Some people also believe it is spread through other means of contact. The following causes below do not cause the H1N1 flu:

- Eating pork, bacon, or ham. Although it was first called the swine flu, eating products derived from pigs does not cause it.

- Going to a pig farm causes the H1N1 flu. Although it is sometimes caused when a person has extensive contact with pigs, it is not the most common cause. Most people who contract the illness catch it from other humans who have never had contact with pigs or other livestock. Simply avoiding farms won't decrease your risk.

- Going to a public swimming pool causes it. The H1N1 flu is only caused through air exposure containing the virus. There have been no reported cases of it spreading through any sort of water contact, including swimming pools.
