H1N1 is swine flu (new Influenza A)
H1N1 is a flu virus that contains a combination of 3 viruses. It is not a pure human virus. In addition to parts of the human flu, H1N1 also contains parts of the swine flu and avian flu. The virus probably originated in Mexico. All flu viruses are also transmitted by birds and not, as is often thought, by pigs. Birds can surrender to pigs. Because pigs are easier to establish than in some birds, it is often assumed that pigs are at the root of the flu virus.
Annoyingly enough, the phenomena appear on the ordinary flu. So in the beginning it is difficult to determine whether you have an ordinary flu among the members or that you are actually infected with the H1N1 virus. The symptoms can vary from mild to very severe. The most important and common symptoms are:
- Fever (38 Degrees or higher)
- Fatigue (feeling loom)
- A dry cough
