World Health Organization officials are
increasingly concerned that a thus far
unexplained outbreak of the bird flu virus could
mean that a long-feared scenario has been borne
out -- that the virus may have mutated so that it
can be passed from one human to another.
The concern began with reports that seven members of one family in a remote Indonesian village had come down with the disease.
Doctors were immediately troubled by the fact that there had been no outbreaks of the disease among birds in the region. To date, all of the more than 200 people infected with the virus have gotten it from contact with a diseased bird.
Health authorities hoped that their investigation would disclose a common contact among the seven infected people. So far, that contact has not been found.
At this point, health officials say they cannot rule out that the seven infected family members passed the virus to each other.
Scientists from the Centers for Disease Control and Prevention have joined their WHO colleagues on the scene to continue the probe.
Unless they can find a connection among all seven family members with one or more diseased birds, they say they may be forced to conclude that a mutation has occurred.
Some scientists have said that if the disease can be transmitted easily among humans, the resulting pandemic could be catastrophic, resulting in millions of fatalities worldwide.
At least 115 of the 208 people known to be infected with the bird flu have died in the last three years, mainly in Asia.
