WHO raportti 8.5. 2023: VOC, VOI, VUM tarkennukset

 VOC määritellään kuten 15. maaliskuuta.

VOI kuten 21.huhtikuuta ja VUM on juuri tarkennettu eilen 8.5. 2023. VUM varianteistä on poistettu XBF ja lisätty XBB.1.9 1 ja XBB.1.9.2 molemmat.  VUM variantteja on  nyt 6 ja niiden järjestys taulukossa ilmaistaan näin:

BA.2.75,

CH.1.1,

BQ.1

XBB*,

XBB.1.9.1.

XBB.1.9.2.

Statement on the update of WHO’s working definitions and tracking system for SARS-CoV-2 variants of concern and variants of interest

Currently circulating variants of concern (VOCs) as of 15 March 2023

Note: To better reflect the current variant landscape, which is dominated by Omicron descendent lineages, WHO updated its tracking system and working definitions of VOCs and VOIs on 15 March 2023.

 

Currently circulating variants of interest (VOIs) as of 21 April 2023

WHO kuvaa tilanteen 4.5. 2023 näin:

Overview

Globally, nearly 2.8 million new cases and over 17 000 deaths were reported in the last 28 days (3 to 30 April 2023), a decrease of 17% and 30%, respectively, compared to the previous 28 days (6 March to 2 April 2023). The picture is mixed at the regional level, with increases in reported cases and deaths seen in the South-East Asia, Eastern Mediterranean, and Western Pacific regions, and decreases in other regions. As of 30 April 2023, over 765 million confirmed cases and over 6.9 million deaths have been reported globally.

In this edition, we include:

• The COVID-19 epidemiological update at the global and the regional levels
• An update on the SARS-CoV-2 variants of interest (VOI) and variants under monitoring (VUM)
• An update on hospitalizations and ICU admissions
