Avian influenza, or bird flu since it is more commonly known, was discovered for a century ago in Italy and to date, there are several variations of the bird flu virus. A great number of strains have become deadly, in particular the H5 and H7 strains. The most serious one to date, the H5N1 strain, has reportedly killed 85 people in Asia only in the last two years. Many experts believe that if proper actions is not taken, bird flu has the potential to be the final major pandemic in the world.Flu has affected the existence of so many people, particularly in the twentieth century. The Spanish Swine flu of 1918, Asian Flu associated with 1957 and Hong Kong Flu with 1968 killed at least 20 thousand people worldwide. Bird virus can spread quickly because bird flu virus is typically perfectly found on the intestines of migrant birds of which travel great distances. Chicken flu spreads when some other birds, chickens or geese come in contact with an infected bird’s spit, nasal secretions or feces. Birds fall ill and die inside of 48 hours of contracting the virus. Humans who interact with afflicted birds without proper protective gear are at risk. There are four reasons that scientists believe that chicken flu could become a crisis.1. Many countries, especially third world countries, do not have the best facilities in place to take care of a bird flu problem. Without these facilities, there is a great possibility of the bird winter flu spreading.2. No vaccine may be fully developed and subjected to testing to fight bird flu virus. Using amantadine and rimantadine, two drugs that happen to be used to treat influenza, upon those infected with the virus has not been successful. Even though research is ongoing, there is still no well-known cure for bird flu around humans. Should a outbreak happen, it will take at least four many weeks to produce vaccines that can be distributed to people suffering from the disease.Three. The avian influenza pathogen affects birds and pigs. On the other hand, because the virus has diverse strains and they easily mutate, professionals fear the virus could advance into something worse and affect humans directly. The herpes simplex virus could become airborne and be transmitted from one human to an alternative.4. People who work in farms and are in the poultry along with livestock industry many not need the proper equipment and adequate protection against the disease.A human who is possibly infected with hen flu could show signs similar to human influenza. A person with bird flu will experience throwing up, sore throat and muscle discomfort. Because of the similarity of signs or symptoms between bird flu plus human flu, a person with fowl flu could be mistakenly diagnosed with human flu. However, advanced symptoms of bird flu include eye infections and the respiratory system problems, which could become deadly.In 1997, when an outbreak of bird flu occurred in Hong Kong, 18 people were infected plus six were killed. For a quick response, Hong Kong’s entire egypr population, which was estimated on 1.5 million, had been killed. Many believe that this particular rapid response to the fowl flu outbreak was the top solution and helped avert it from becoming a pandemic. In general, there is little risk of a lot of people getting infected with bird flu since it requires close as well as direct interaction with contaminated birds or bird waste material. Since the number of people that has been who have contracted the disease is still low as well as confined to a few children and adults, there is no serious cause of alarm but. However, for those who have constant hitting the ground with birds, the risk becomes extremely high during outbreaks in nearby poultryBecause of the constant and quick advances in technology currently, in addition to lessons learned from past major pandemics, there may be hope that bird swine flu will be prevented from turning into another global pandemic.
