WHO notes two clusters in recent H7N9 cases from China

Two clusters are among a group of 23 H7N9 avian influenza cases reported by China on May 13, the World Health Organization (WHO) said today in an update.

Seven of the patients died from their infections and 15 had either pneumonia or severe pneumonia; 1 had a mild infection. Nineteen had been exposed to poultry or live poultry markets, one had contact with a hospitalized patient, and one had exposure to both poultry and a previously confirmed case-patient. The two remaining case-patients had no known poultry exposure.

All of the patients were adults who hailed from Beijing and 10 different provinces.

The first cluster includes a 63-year-old man from Shaanxi province who was hospitalized on May 2 with a mild illness after visiting a confirmed case-patient in the hospital, a 62-year-old man from the same province. The other involves a 37-year-old woman from Hebei province who was hospitalized on May 3 with pneumonia. She had raised backyard poultry but also had contact with her 62-year-old mother who had been sick with an H7N9 infection in the middle of April.

In its risk assessment, the WHO said that although small clusters of H7N9 illnesses have been reported, including patients in the same hospital ward, so far evidence suggests the virus doesn't spread easily among humans and the likelihood of further community spread is low.

Since the virus was first detected in humans in 2013, the WHO has received reports of 1,486 cases. Most are from China, which is still in the midst of its fifth and biggest wave of illnesses and in which at least 700 cases have been reported since October.

North China province reports new H7N9 case

Source: Xinhua| 2017-05-24 14:25:14

TAIYUAN, May 24 (Xinhua) -- North China's Shanxi Province Wednesday reported its second human infection of the H7N9 bird flu virus.

Duan, 57, a farmer from Xinzhou, showed symptoms including a fever and cough in early May. He has been receiving treatment at the No. 4 People's Hospital in the provincial capital Taiyuan since the infection was confirmed Tuesday, according to the Shanxi health and family planning commission.

The province reported its first H7N9 case in mid-May.

H7N9 is a bird flu strain first reported to have infected humans in China in March 2013.

Experts recommend avoiding contact with birds, and only buying certified poultry.
