Swine flu: causes, symptoms, and prevention
Swine flu (swine influenza, pig flu) is a variety of influenza virus that usually infects pigs. Swine flu typically is spread from pig to pig. However, the swine flu becomes dangerous when it spreads from pigs to humans and then from one human to another. Humans who have been infected with the swine flu tend to present with symptoms that are similar to the typical influenza virus such as fever, chills, sore throat, aches andpains, and weakness.
The current swine flu outbreak is a new strain of influenza A virus with the subtype of H1N1. It has raised alarms simply because of the fact we have no vaccinations prepared to combat this particular strain. However, it does seem the this strain of swine flu is not necessary very aggressive and deadly. Yet, caution must still be taken.
Prevention:
The swine flu, just like any other influenza virus, spreads via water droplets that are released during sneezing or coughing. Thus, in order to prevent the spread of swine flu, the same precautions need to be taken as used to prevent any influezna virus. People should cover their mouths during coughing or sneezing, wash your hands with soap or alcohol-based hand rub, and disinfect surfaces such as counter or table tops and door knows.
If you began to come down with flu-like symptoms such as fever, cough, chills, or aches, you should immediately contact a physician and avoid using public transportation or going out in public places.
