In recent years there has been an outbreak of H5N1 virus affecting birds in Asia, Europe and Africa, the mortality rate is high. Many cases of infection were recorded, but the risk of bleach in a possible development of a new, more powerful virus. Viruses are the main causes of avian influenza or bird flu. The disease is carried by wild birds, without being affected. However, the poultry, the disease ranges from mild to severe, which are lethal. The effort resulted in more deaths, both in poultry and humans around the world are the highly pathogenic H5N1 virus spreads easily. Moreover, once the H5N1 virus has been detected in several parts of the world such as South Korea, Asia, Europe and the Middle East, which shows that bird flu is very easy to transmit. For a country that has been affected by this quarantine against influenza is entitled to three months after the evidence suggests that the virus is not present.
In addition, research shows that H5N1 is annoying and can pass to humans. Bird to human transmission is possible in the communities where people are in close relationship with domestic poultry. More risk includes poultry farms and markets, as the virus persists on surfaces and in secretions. The symptoms of bird flu can range from conjunctivitis and flu-like manifestations (fever, sore throat, cough) and more serious, like pneumonia, acute respiratory infections, viral pneumonia, which can lead to death.
Finally, we can say that current data on the H5N1 virus is of concern and reinforces the need for an effective drug to prevent the spread of illness and death of those affected. Furthermore, the ability of the virus to alter its genetic structure and to combine with other viruses to create a vaccine requires that before.
