Influenza update 1 December 2014 - Update number 225

Opublikowano nowe dane WHO dotyczące zachorowalności na grypę.

Za wyjątkiem niektórych wysp Pacyfiku aktywność grypy jest generalnie niska. W Europie mamy jak dotąd szczęście, choć aktywność grypy nieco wzrosła, nadal pozostaje niska. Szczegóły w tekście i na załączonej mapce. Google potwierdza dane WHO. Ludzie nie szukają jeszcze informacji o grypie, zatem problem jeszcze nie wystąpił. Nic dziwnego, dopiero od kilku dni się wyraźnie ochłodziło.

Cytuję:
  • In North America, influenza activity continued to increase.
  • In Europe overall influenza activity increased slightly but remained low.
  • In tropical countries of the Americas, influenza detections remained low with respiratory syncytial virus (RSV) causing most influenza-like illness (ILI) and severe acute respiratory infections (SARI).
  • In Africa and western Asia, influenza activity was low.
  • In eastern Asia, influenza activity in most countries remained low.
  • In tropical Asia, influenza activity was low with influenza B predominant in Viet Nam.
  • In the southern hemisphere, influenza activity remained low except in several Pacific Islands where ILI activity remained high.
  • The review of the southern hemisphere influenza season has been published at the WHO website see link below
  • Based on FluNet reporting (as of 27 November 2014, 14:25 UTC), during weeks 45 to 46 (2 November 2014 to 15 November 2014), National Influenza Centres (NICs) and other national influenza laboratories from 45 countries, areas or territories reported data. The WHO GISRS laboratories tested more than 34 452 specimens. 2572 were positive for influenza viruses, of which 2123 (82.5%) were typed as influenza A and 449 (17.5%) as influenza B. Of the sub-typed influenza A viruses, 27 (2.9%) were influenza A(H1N1)pdm09, 917 (97.0%) were influenza A(H3N2) and 1 (0.1%) was influenza A(H5). Of the characterized B viruses, 34 (94.4%) belonged to the B-Yamagata lineage and 2 (5.6%) to the B-Victoria lineage.
  • Due to changes in data collection platforms, data from the WHO Regional Office for Europe are temporarily not available at the global level. Those data will be uploaded to FluNet and FluID as soon as possible. Information on European influenza activity can be found at http://www.flunewseurope.org/
