 Chinese researchers warn that the chances of stamping out the bird flu virus altogether are slim.
In a study of the genetic ancestry of the so-called H5N1 virus, researchers say the risk can only be reduced and delayed by present measures.
They warn that the proximity of farm fowl to humans continues to pose a threat.
That proximity can harbour both avian and human viruses and act as a vessel to mix them.
Researchers are concerned it may create a virus that would be lethal and transmissible among humans.
The study by Chinese researchers from the University of Hong Kong and Shantou University Medical School is about the genetic identity of the so-called Z genotype, or strain of the H5N1 virus.
The study, published on Thursday in the British weekly science journal Nature, coincides with the outbreak of a new case of bird flu in China's Anhui province as well as confirmed and suspected cases in Vietnam and Thailand.
*********************************************
Internet regulators around the world have launched a "fight back against spam" campaign and pledged to develop a global anti-spam strategy.
Regulators from about 60 countries and regions met at the International Telecommunication Union in Geneva.
They discussed the growing plague of unwanted e-mails and phone messages that threaten the survival of the internet.
They suggested a co-operative effort should be made between governments and industries.
Spam is defined as unsolicited electronic messages. It now accounts for more than half of e-mails and a growing proportion of phone messages.
Spam costs the world an estimated $25 billion a year in lost productivity and extra security measures.
The main "spammer" source countries are the US, followed by China, South Korea, Brazil and Canada.
*********************************************
Apple has said that it would end the waiting and launch its iPod mini digital music player around the world on July 24.
The popular music player is capable of holding up to 1,000 songs on its 4-gigabyte hard drive. | |
