China, Shandong: A 74-years-old patient recovered from H7N9 influenza infection

___

(…)

On June 21 afternoon, an H7N9 influenza virus infected patient was discharged from Binzhou Medical College Hospital.

(…)

However, throughout the treatment process, and not so easy.

On May 12 a male patient was admitted to hospital, with fever which lasted for 6 days; less than 24 hours since hospital admission, he showed symptoms of respiratory failure, the disease developed rapidly. At that time, the attending doctor Wang Xiaizhi recognized that his illness was unusual, and after the other respiratory viruses were checked and ruled out, on May 19, the patient was diagnosed with H7N9 virus infection.

During the whole treatment process, the patient received careful treatment by medical staff, more than a dozen pipelines, ventilator parameters, appetite, sputum volume, urine volume, volume and other types of values ​​have been accurately recorded, in vitro cardio-pulmonary oxygenation And other life support equipment to make every effort to retain the patient's life.

"Light patients do prone position ventilation when you need 6 people together to help turn over, but we did not because the virus is contagious and the slightest resentment and complaints, fearless, the personal safety of the degree, 24 hours alternate guardian." Wang Xiaoshi said , "In the patient during the diagnosis of the hospital to join the anti-viral treatment, no hormones, treatment in place, accurate, did not take a little detour, which ensures the progress of treatment of patients, this time in the province of virus infection treatment is the fastest "

____

National Influenza Centres (NICs) and other national influenza laboratories from 84 countries, areas or territories reported data to FluNet for the time period from 29 May 2017 to 11 June 2017 (data as of 2017-06-23 08:49:26 UTC).

The WHO GISRS laboratories tested more than 61275 specimens during that time period.

4815 were positive for influenza viruses, of which 3286 (68.2%) were typed as influenza A and 1529 (31.8%) as influenza B.

Of the sub-typed influenza A viruses, 757 (31.5%) were influenza A(H1N1)pdm09 and 1648 (68.5%) were influenza A(H3N2).

Of the characterized B viruses, 134 (37.1%) belonged to the B-Yamagata lineage and 227 (62.9%) to the B-Victoria lineage.
