It is not yet clear whether the Omicron COVID-19 variant is more transmissible, or causes more severe disease compared to other variants including Delta, the World Health Organization said on Sunday.。
WHO said it's not yet clear whether Omicron is more easily spread from person to person compared to other variants, even though the number of people testing positive has risen in South Africa where this variant was involved.。
It's also not yet clear whether Omicron causes more severe disease, but preliminary data suggests that there are increasing rates of hospitalization in South Africa, which however may be due to increasing overall numbers of people becoming infected.。
WHO confirmed that there is currently no information to suggest that symptoms associated with Omicron are different from those from other variants, as understanding the level of severity of the Omicron variant will take days to several weeks.。

All variants of COVID-19, including the Delta variant that is currently dominant worldwide, can cause severe disease or death, in particular for the most vulnerable people, and thus prevention is always key.。
However, WHO said preliminary evidence suggests there may be an increased risk of reinfection with Omicron, but information is limited. More information on this will become available in the coming days and weeks.。
It added that current PCR tests continue to detect Omicron, while further studies are still going on to understand how the Omicron variant will impact on available vaccines and treatments to COVID-19.。
WHO classified on Friday the latest variant B.1.1.529 of SARS-CoV-2 virus, now with the name Omicron, as a "Variant of Concern" (VOC).。
According to WHO's definition, a VOC, with a degree of global public health significance, demonstrates one or more of mutational changes, such as increase in transmissibility or detrimental change in COVID-19 epidemiology, increase in virulence or change in clinical disease presentation, and decrease in effectiveness of public health and social measures or available diagnostics, vaccines, therapeutics.。
WHO has since called on countries to enhance surveillance and sequencing on circulating SARS-CoV-2 variants, submit complete genome sequences and metadata to a publicly available database, and report initial VOC cases or clusters to WHO.。
It has also recommended field investigations and laboratory assessments to better understand potential impacts of the VOC on COVID-19 epidemiology, the effectiveness of public health and social measures and antibody neutralization.。
LaLiga: Athletic Club beat Villarreal, Valencia stage late fightback******
MADRID, Oct. 23 (Xinhua) -- Athletic Club Bilbao inflicted Villarreal's first away defeat of the season as they claimed a 2-1 win in the San Mames Stadium that was close to capacity for the first time since March 2020.
Raul Garcia put Athletic ahead from Inaki Williams' cross in the 14th minute, but Francis Coquelin's deflected effort leveled the score in the 32nd minute.
Man of the match Iker Muniain won the game from the penalty spot in the 77th minute after Unai Vencedor had been fouled by Alberto Moreno and it would have been 3-1 a couple of minutes later but Villarreal keeper Geronimo Rulli did well to stop a second spot kick taken by Alex Berenguer to assure a nervy finish.
Valencia came back from 2-0 down at home to Mallorca to claim a point with two goals in injury time.
Angel Rodriguez and a Mouchtar Diakhaby own goal put Valencia on the ropes in the first half, but Kang In Lee, who set up Angel for the opener, had a rush of blood 10 minutes into the second half and left his side with 10 men.
Mallorca still looked as if they were going to hang on, but they got nervous when Goncalo Guedes fired home from long range in the 92nd minute and Jose Luis Gaya's close range finished earned Valencia a point in the 98th minute
Two goals from striker Joselu, the first of which came from the penalty spot after just six minutes, gave Alaves their first away win of the season and just their second victory of the entire campaign, as Javi Calleja's side won 2-0 away to Cadiz.
Elche and Espanyol shared four goals with Manu Morlanes and Raul de Tomas netting goals within 2 minutes on 51 and 52 minutes to cancel out Lucas Boye's first half opener for Elche, who claimed a point with Dario Bernadetto's 84th minute equalizer.
Cadiz slip deeper into trouble after failing to win in their last seven home games.
Friday night saw Osasuna go second in the table with a 1-1 draw at home to Granada, but the team from Pamplona will be disappointed after Granada scored a 90th minute equalizer from Angel Moreno to cancel out Chimy Avila's opener on the stroke of halftime.
Osasuna ended with 10 men after left back Jose Angel 'Cote' was sent off with 16 minutes left to play. Enditem
