One of the two new cases was in the southeastern English town of Brentwood, while the other was in the central city of Nottingham. The two<br \/>\nconfirmed cases are self-isolating with their households while contact tracing and targeted testing takes place.<\/p>\n<p>The British government also added four more countries \u2014 Angola, Malawi, Mozambique and Zambia \u2014 onto the country\u2019s travel red list from Sunday. Six others \u2014 Botswana, Eswatini (formerly Swaziland), Lesotho, Namibia, South Africa and Zimbabwe \u2014 were added Friday.<br \/>\nThat means anyone permitted to arrive from those destinations will have to quarantine.<\/p>\n<p>Many countries have slapped restrictions on various southern African countries over the past couple of days, including Australia, Brazil, Canada, the European Union, Iran, Japan, Thailand and the United States, in response to warnings over the transmissibility of<br \/>\nthe new variant. This goes against the advice of the World Health Organization, which has warned against any overreaction before the variant was thoroughly studied.<\/p>\n<p>Despite the banning of flights, there are mounting concerns that the variant has already been widely seeded around the world. In addition to the U.K, cases have been reported in travelers in Belgium, Israel and Hong Kong.<\/p>\n<p>The Dutch public health institute said the omicron variant was \u201cprobably found in a number of the tested persons\u201d who were isolated after arriving Friday in Amsterdam on two flights from South Africa. The institute said in a statement that further sequencing analysis is underway to determine for sure that it is the new variant. The results were expected Sunday. A total of 61 people were tested.<\/p>\n<p>Germany also said it suspected three positive cases, while Italy was investigating a positive case from someone recently returned from southern Africa. And Israel said it was tracing 800 travelers who returned recently from southern African countries.<\/p>\n<p>The variant\u2019s swift spread among young people in South Africa has alarmed health professionals even though there was no immediate indication whether the variant causes more severe disease.<\/p>\n<p>A number of pharmaceutical firms, including AstraZeneca, Moderna, Novavax and Pfizer, said they have plans in place to adapt their vaccines in light of the emergence of omicron. Pfizer and its partner BioNTech said they expect to be able to tweak their vaccine<br \/>\nin around 100 days.<\/p>\n<p>Professor Andrew Pollard, the director of the Oxford Vaccine Group, which developed the AstraZeneca vaccine, expressed cautious optimism that existing vaccines could be effective at preventing serious disease from the omicron variant, noting that most of the mutations appear to be in similar regions as those in other variants.<\/p>\n<p>\u201cAt least from a speculative point of view we have some optimism that the vaccine should still work against a new variant for serious disease, but really we need to wait several weeks to have that confirmed,\u201d he told BBC radio.<\/p>\n<p>Some experts said the variant\u2019s emergence illustrated how rich countries\u2019 hoarding of vaccines threatens to prolong the pandemic.<\/p>\n<p>Fewer than 6% of people in Africa have been fully immunized against COVID-19, and millions of health workers and vulnerable populations have yet to receive a single dose. Those conditions can speed up spread of the virus, offering more opportunities for it to<br \/>\nevolve into a dangerous variant.<\/p>\n<p>\u201cOne of the key factors to emergence of variants may well be low vaccination rates in parts of the world, and the WHO warning that none of us is safe until all of us are safe and should be heeded,\u201d said Peter Openshaw, a professor of experimental medicine at<br \/>\nImperial College London.<\/p>\n<div id=\"antig-320315951\" class=\"antig-after-first-paragraph\">\n<h5><\/h5>\n<\/div>\n<div id=\"antig-722466631\" class=\"antig-in-comments_2 antig-entity-placement\"><a href=\"https:\/\/www.facebook.com\/@hadeedmotorsltd\" aria-label=\"Hadeed_WEB_Banner_MG-2\"><img src=\"https:\/\/mlavawteztbj.i.optimole.com\/w:1000\/h:250\/q:mauto\/f:best\/https:\/\/antiguanewsroom.com\/wp-content\/uploads\/2024\/12\/Hadeed_WEB_Banner_MG-2.png\" alt=\"\"  srcset=\"https:\/\/mlavawteztbj.i.optimole.com\/w:1000\/h:250\/q:mauto\/f:best\/https:\/\/antiguanewsroom.com\/wp-content\/uploads\/2024\/12\/Hadeed_WEB_Banner_MG-2.png 1000w, https:\/\/mlavawteztbj.i.optimole.com\/w:300\/h:75\/q:mauto\/f:best\/https:\/\/antiguanewsroom.com\/wp-content\/uploads\/2024\/12\/Hadeed_WEB_Banner_MG-2.png 300w, https:\/\/mlavawteztbj.i.optimole.com\/w:768\/h:192\/q:mauto\/f:best\/https:\/\/antiguanewsroom.com\/wp-content\/uploads\/2024\/12\/Hadeed_WEB_Banner_MG-2.png 768w\" sizes=\"(max-width: 696px) 100vw, 696px\" width=\"1000\" height=\"250\"   \/><\/a><\/div>","protected":false},"excerpt":{"rendered":"<p>LONDON (AP) \u2014 The U.K. tightened up rules Saturday on mask-wearing and on testing of international arrivals after finding two cases of the new potentially more contagious omicron variant of the coronavirus that was identified just a few days ago in South Africa.
