What is the bird flu?

For more than a century, bird flu spread among birds, especially domesticated poultry, but recent attention was alerted to bird flu from some tribes of infected people. Bird flu is no longer included in pigs and birds because the virus has strengthened and mutated, leading to infection that can move from the bird to man. Human cases of bird flu caused infections and death around the world because scientists seek to identify dangerous tribes and prevent fatal pandemic.

We knew for a long time that bird flu had existed in animals and often killed wild and domestic populations. These viruses are one of the related flu types that develop and mutate as much as any virus. We have previously dealt with the loss of valuable birds who provided eggs or meat to poultry farmers. In 1997, however, it changed when it seemed that bird flu showed fatal for people in Hong Kong.

The pathogenic or active bird flu strain quickly kills birds and quickly expands by the population. IfA wild, migratory bird catches the flu, can transfer it many kilometers to other wild or domesticated groups. These viruses develop in two ways, drift and shift. drift concerns inaccurate replication, so newer viruses are further from the original genetic material, but share enough DNA that they still spread only between one species. When the virus moves , it means that the genes of one viral mixture or breed with another virus usually inside the carrier. Due to the shift, the bird flu was mixed with the human type of flu and was able to infect people with direct contact with birds.

Human cases of bird flu are incredibly alarming and have been concerned about virologists and government agencies in China, Hong Kong, Vietnam, Canada and other countries. This immediate pandemic could only be dominated by a huge defeat of millions, which contains a virus that spreads air, water and soil. Bird flu is particularly dangerous because our immune systems do not needNot antibodies that could handle something that was previously included in animals. It is therefore maintained by unprecedented force, settles in the lungs and resists antiviral and antibacterial drugs.

Most health experts examining and fighting the incidence of human bird flu has no optimistic outlook. They point out that the pathogen seemed not to develop so that people's contact with a person is contagious, yet it remains that people working with poultry, swimming in infected rivers, playing in an area where carcasses were buried, or breathing air near the poultry plant can lead to infection.

So far, doctors have been able to diagnose bird flu, identify a specific strain and focus on the correct disposal of infected birds. Yet they are ineffective in the treatment of the resulting respiratory infection, leading to fatititiis. They note that influenza and pandemic epidemics seem to be inevitable due to the history of contagious disease over the past few centuries.
