Bird Flu and Human Transmission

The human transmission of bird flu is rarely observed, but once occurred it can result into deadly consequences. More than 100 confirmed cases of human infection with bird flu viruses have been reported since 1997.

The incident occurring in Hong Kong has proved its hazardous effects. The H5N1 virus affected 18 people out of which 6 died. H5N1 is of particular concern for several reasons. H5N1 mutates rapidly and has a documented propensity to acquire genes from viruses infecting other animal species. Its ability to cause severe disease in humans has now been acknowledged on two occasions. Studies reveal that isolates from this virus have a high pathogenicity and can cause severe disease in humans.

Bird Flu Transmission
The birds that are infected from this disorder shed flu virus in their saliva, nasal secretions, and feces. Susceptible birds become infected when they have contact with contaminated excretions or surfaces that are contaminated with excretions. The most common factor for the transmission of bird flu in human being is believed to be the gradual contact with infected poultry or contaminated surfaces but the spread of bird flu virus from one person to another hasn't been observed yet.

Early Indications of Bird Flu
Early indications of bird flu are fever, cough, sore throat, muscle aches, eye infections, pneumonia and severe respiratory diseases such as acute respiratory distress. The disease can lead to life threatening consequences. The intensity of the symptoms of bird flu generally depends on the virus that caused the infection.

Bird Flu Treatment
Till date, a specific anti-avian influenza vaccine for humans is not readily available. However, the U.S. Centers for Disease Control and Prevention has suggested that the anti-viral medication oseltamivir phosphate, with brand name Tamiflu, may be effective in treating avian influenza.
