What causes people to suffer or suffer diseases Bird Flu? Cause of Bird Flu Disease is a virus influenza A subtype H5N1. Influenza Vrus is included in the type or class of viruses are pathogenic for humans influenza, namely type A, b and C. Virus Influenza A spiral-shaped symmetrical and has a casing that encloses genetic material in the form of RNA (ribonucleic acid), a single chain has a negative polarity. This virus has two kinds of projections, namely haemagglutinin (u) and neuraminidase (N), strain (strain), type 'A' will be coded according to antigenic properties and haemagglutinin (H) and neuraminidase (N), as shown in the following example: H1N1, H2N2 , H3N2, or H5N1. And, there are 16 subtypes of H (h1-H16) and 9 N subtypes (N1-N9).
In the virus can occur influenza A big change in the composition antigenitiknya called antigenicity small shifts or changes in the antigenic composition is called antigenic drift. These changes lead to an epidemic or even pandemic.
The wave of the epidemic because the virus influenza A place periodically every 2-3 years, while the period of interpidemi to influenza B is longer ie 3-6 years. Every 10-40 years, when there influenza A virus subtype new, there will be a pandemic as happened in 1918 (H1N1), 1957 (H2N2), and in 1968 (H3N2). In the year 1997 has emerged a new subtype of H5N1, although until now has not resulted in a pandemic.
In humans there is only influenza A virus of the subtype H1N1, H2N2, H3M3, H5N1, H9N2, H1N2, and H7N7, whereas in animals is a subtype H1 to H5 and N1 to N9.
Of all these subtypes, only influenza A virus subtypes H5 and H7 that have been known to cause of highly malignant disease. However not all influenza viruses H5 and H7 subtypes are lethal, and also not all cause disease in poultry animals.
What is the nature of bird flu virus (H5N1)?
Important and is something that we should all know that we can avoid the adverse effects of the virus. At least we have the basic knowledge to be able to avoid the bird flu disease caused by the H5N1 virus.
Some properties of avian influenza virus (H5 N1) is:
- Easy to change shape and perform mutation.
- Survive life in water up to 4 hearts at 22 degrees Celsius and more than 30 days at 0 degrees C.
- Survive live longer in the body in feces or sick birds
- Dead at 80 Degrees Celsius warming subs 1 minute, or with a temperature of 60 degrees Celsius for 30 minutes and at a temperature of 56 degrees Celsius for 3 hours.
- Off with detergent, disinfectant (such as formalin), the liquid containing iodine (such as betadine) and potassium sodium hypochlorite (ie bleach clothes).
