The avian influenza virus must change. The virus can change to become more contagious among humans in two ways. The first is a "reassortment" event, in which genetic material is exchanged between human and avian viruses during co-infection of a human or pig. Reassortment could result in a fully contagious pandemic virus.

Studies done in laboratories suggest that the prescription medicines approved for human flu viruses should work in preventing bird flu infection in humans. However, flu viruses can become resistant to these drugs, so these medications may not always work. Additional studies are needed to prove the effectiveness of these medicines

The risk from bird flu is generally low to most people because the viruses occur mainly among birds and do not usually infect humans. However, during an outbreak of bird flu among poultry (domesticated chicken, ducks, turkeys), there is a possible risk to people who have contact with infected birds or surfaces that have been contaminated with excretions from infected birds.

Symptoms of bird flu reported in humans have ranged from typical influenza-like symptoms (fever, cough, sore throat, and muscle aches) to eye infections, pneumonia, acute respiratory distress (difficulty breathing), viral pneumonia and other severe and life-threatening complications. Only if you have recently returned from travel to an area where bird flu is present. Depending on your symptoms, dates of travel, and activities, additional testing might be recommended.

Infected birds 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. It is believed that most cases of bird flu infection in humans have resulted from contact with infected poultry or contaminated surfaces.

A person infected by bird flu may have all symptoms of common flu like fever, persistent cough, sore throat and body ache. Moreover, there is a high risk of complications such as pneumonia, bronchitis, eye and ear infections and severe breathing problems. The most effective drugs known for seasonal flu are Oseltamivir (commercial name Tamiflu) and Zanamavir (Commercial name Relenza).

Unfortunately, yes. About 200 people, most of them in Vietnam, Thailand, Indonesia, or China, have developed a human form of the disease, typically from direct contact with infected birds among the poultry flocks that live and roam freely in rural villages.

It is believed that most cases of bird flu infection in humans have resulted from contact with infected poultry or contaminated surfaces. There is no evidence of human-to-human transmission so far.

Bird Flu" or Avian Influenza is a highly contagious viral disease that can classified as either low pathogenic (low mortality) or high pathogenic (up to 100% mortality). Low Pathogenic Avian Influenza like the common flu in humans is a common annual event in birds. High Pathogenic Avian Influenza like the H5N1 virus circulating in Asia, Europe, and Africa is less common.

Yes, bird flu can infect humans and the disease can be fatal. Keep in mind that at this stage the disease remains a rare event.

If Avian Influenza changes and becomes contagious human to human it would start a flu pandemic. An especially severe influenza pandemic could lead to high levels of illness, death, social disruption, and economic loss. Everyday life would be disrupted because so many people in so many places become seriously ill at the same time. Impacts can range from school and business closings to the interruption of basic services such as public transportation and food delivery.

The flu virus becomes contagious one day before you feel sick. The virus enters through your nose, throat, or lungs from the air. It then begins to multiply, usually causing symptoms within a day or two. Children, on the other hand, can pass the virus on for more than a week. You can contract the flu if you touch a surface that has the flu virus on it and then touch your nose or mouth.

Bird flu is transmitted to humans from direct or indirect contact with infected wild ducks and chickens through infected aerosols, discharges and surfaces. Based on present knowledge, there appears to be no risk of transmission of the H5N1virus to humans from raw, chilled or frozen poultry foods. Since the virus is easily inactivated by heat, one does not get bird flu from thoroughly cooked chicken meat.
