The World Health Organization (WHO) experts have confirmed the first case of inter-human bird flu infection in Pakistan.

However, WHO stated that there was no obvious possibility of its widespread eruption.

In a statement, the U.N. agency said that examinations had founded that the person was infected with the deadly H5N1 virus, even though he had not been in contact with infected poultry.

A spokesman John Rainford told, “Because we have an individual not directly exposed to sick birds suggests a limited human-to-human transmission.”

In the recent months, this human-to-human infectivity has been reported in Cambodia, Indonesia and Vietnam. But it hathere were no reports  not spread beyond a single person. A suspected case in China was denied by the authorities there.

In the most recent Pakistani case, a WHO report stated that prelim examinations had detected no proof of sustained or community human to human transmission.

It added, “All identified close contacts including the other members of the affected family and involved health care workers remain asymptomatic and have been removed from close medical observation.”

Specialists fear that if the H5N1 strain changes into a highly infectious form, it would incite an epidemic on the scale of the 1918 Spanish flu outburst that took tens of millions of lives.

The WHO team was sent after the agency declared the death of a man who was among the six people infected with the H5N1 strain in North West Frontier Province along the Afghanistan border.

A victim’s brother also died before being examined for the disease. Both had worked on a cull of contaminated poultry.
