Bird Flu Spreads Human-to-Human, Admit Chinese Authorities

The Chinese authorities on Jan. 27 acknowledged for the first time that they have discovered cases of human-to-human infection with the H7N9 bird flu, while remaining vague on the details in an attempt to prevent public panic.

In a short statement on Jan. 27, the authorities said that human-to-human transmission was recorded in eastern Chinas Zhejiang Province. They do not specify the number of cases, nor the city in which they took place.

The H7N9 Joint Prevention and Control Office said the infection or infections took place under particular conditions and are non-sustained transmissions, meaning that it is not expected to spread from those incidents.

The case or cases in Zhejiang would be the first time that human-to-human transmission has been officially acknowledged by the authorities since H7N9, a new avian influenza, was first recorded in China in March 2013.

Experts at the China Center of Disease Control, however, said it was just a special case, and human-to-human transmission of H7N9 is not yet very widespread.

The public has no need to panic too much, said Xinhua, the mouthpiece of the Chinese Communist Party.

Zhejiang has a bad record with H7N9 infections: it has recorded 49 diagnosed cases and 12 deaths this month, the latest official report says.

A newly released Treatment Scheme of Human Infection with H7N9 Bird Flu by Chinas Health and Family Planning Commission also now lists limit and non-sustained human-to-human infection as one of the ways in which the H7N9 virus may be transmitted.

More common transmission mechanisms include infection through the respiratory tract, through close contact with secretions or excretions of infected birds, and through contact with the infected environment.

Despite the authorities attempts at damage control in emphasizing the limited nature of human-to-human transmission, the news still came as highly unwelcome to the public. Many individuals posting on the Internet said they would avoid eating poultry, in order to protect themselves from contracting the virus. (Though it does not spread from the consumption of chicken meat.)
