Swine Flu - What is it and how to avoid them

Basics

Swine flu) is caused by an influenza virus (H1 N1. We must first explain what type and which are H & N main categories are divided into three influenza viruses A, B and C, A-influenza virus causing outbreaks in worldwide (pandemic) of, B virus causes serious outbreaks, while C virus causes only mild respiratory infections. The influenza A virus, caused by pandemics occur almost every 10-20 yearsbut there are major epidemics caused by this virus almost every year in different countries.

The key to the persistence of virus genetic material is his and antigenic composition. It 'important surface antigens hemagglutinin (H) and neuraminidase (N). The H antigen is the association used to host cells, while the N antigen divided budding viruses from infected cells. Four haemagglutinin subtypes (H1, H2, H3 and H5) and N-antigen has two (N1 and N2) that have caused human disease.Changing the surface antigens, or (Shift) over time. H & N antigens change continuously reflects changes in their genome, where antigenic shift occurs when a major change occurs in the antigen and this movement often leads to a pandemic, because people often have little or no preexisting immunity against the new strain.

Type of infection

spread of swine influenza virus or any other flu virus is spread by dropletsAerosols.

Incubation period

1-4 days (the time before the onset of symptoms).

Clinical manifestations

Unfortunately, swine influenza has the same symptoms as normal human influenza, and this includes:

sudden increase in body temperature, cough, malaise, anorexia, headache, muscle aches, runny nose and shortness of breath (you may or may not be accompanied by vomiting andDiarrhea).

Laboratory Diagnostics

Swine flu is the disease diagnosed nasopharyngeal swabs, washes or blows the taking of specimens in the first. The virusus are fragile and must be handled with care, and samples must not be frozen.

Prevention

Since there is no treatment yet the only way we can prevent infected or to improve our immunity is, for the following measures:

- Avoid crowds (you canWear masks) - Avoid kissing when you are not the kisser - Wash hands often with soap and water (especially when you sneeze) - Always a good airing - Drinking water and fluids as possible especially Ginger (increase immunity) - foods that help increase immunity melon, apple, guava, honey, lettuce and radishes - with vitamins, especially vitamin A and C and antioxidants.

I hope this information helps you overcome this difficult time.
