Is H5N1 flu transitioning to a human-to-human illness? Recent reports of familial clusters suggest that it may be, though there are certainly other possible explanations, such as families living in environments contaminated by virus-laden bird feces. On the other hand, it would seem that epidemiologists are growing increasingly interested in the possibility that these clusters are indicative of human-to-human transmissions. Further, the virus may be inching towards being asymptomatic, which isn't as good as it sounds: if people can carry the virus and transmit it to others without showing symptoms, it will be very difficult to impossible to tell who is a vector and highly difficult to control any emerging epidemic.
