Swine flu
With so much attention in the news on swine flu, it’s wise to know the basics of what it is, what you can expect, and how to protect yourself and your loved ones from swine flu. Knowledge may alleviate your fear of swine flu.
There were six cases of swine flu reported in South Africa up to 29 April 2009 while countries throughout the world were reported to be in a panic mode over a possible epidemic, the SA National Institute for Communicable Diseases (NICD) said. It is best to know about the flu and to be prepared.
What is swine flu?
Swine flu is a strain of virus that pigs contract and transmit. The swine flu of interest this year is the H1N1 strain which can be passed from pigs to human beings. It was first identified in pigs in 1930. Now it can be transferred from human to human having the possibility of creating a pandemic.
Why is this flu different from other flues?
Influenza is caused by a virus. There are probably thousands of different kinds of viruses that can cause the flu. The seasonal flu is actually several different strains, and each year those strains seem to change. Swine flu is just one more strain.
Difference between swine flu and avian flu
Avian flu is another name for bird flu. Swine flu seems to be a combination of human flu and avian flu.
How is swine flu transmitted?
Just the way any viral disease is transmitted – person to person contact, or by touching something someone with a virus has already touched, or from droplets in the air which come from a sneeze or a cough of a person who has swine flu.
What are the symptoms of swine flu?
Typical flu symptoms appear. Fever, cough, sore throat, body aches, headache, chills and fatigue are the most prevalent symptoms. Some patients report diarrhoea and vomiting, too.
Do people die from swine flu?
People can die, but most do not. In Mexico more than a hundred deaths are already reported as well as many more cases of swine flu.
Who is most at risk for catching swine flu?
Like any contagious disease, older people, babies or anyone with a compromised immune system are vulnerable to a flu virus. However, what it is unusual about swine flu is that healthy people seem to be most at risk. Health professionals theorise that a stronger immune system may cause the body to develop highly vigorous antibodies to attack the virus, and those antibodies inflame the lung cells, making healthy people even sicker. People who died from swine flu in Mexico were mostly older than three and younger than 60. The cases so far reported in the US seem to be younger than 65.
Are you safe from swine flu in South Africa?
No. Any contagious disease can easily be transmitted around the world within a very short period of time because people don’t stay in one place. Vacationers and business travellers may go to or leave Mexico or any other area where swine flu is prevalent. Any of them may have been exposed to the flu. If they are contagious, they may transmit the virus on planes, trains, in airports or other travel-related places, exposing others. And then they take it home with them.
You got a flu vaccine, so are you protected?
The authorities say that a seasonal flu vaccine can protect you from swine flu, if it includes the H1N1 strain.
