View Summary
Although avian influenza (H1N1), or bird flu, might not be getting as much attention since the first cases were found in Hong Kong in 1997, it hasn’t gone away and still infects and kills dozens of persons every year. Researchers remained concerned about its potential to cause a large-scale, global outbreak. Because Hong Kong is one of the world’s most densely populated places, persons living there are at high risk for a rapidly spreading outbreak, particularly because wholesale markets selling live poultry are common. Do Hong Kong residents still perceive that they are at risk for bird flu, and are they taking the right steps to prevent it? One study surveyed Hong Kong residents over time and found that they are less worried about buying live poultry and about contracting with bird flu. These changes in perception of risk were associated with a decline in handwashing and covering coughs and sneezes, both of which help prevent influenza infections. A second study focused on poultry workers in Hong Kong and found a low level of knowledge about bird flu. Although many workers knew the symptoms, they were less likely to know how the disease is spread and how deadly it is. They also reported moderate to low levels of hand hygiene and other preventive measures.
