Covid evolving differently: Experts on how new waves will emerge

Reading now: 761

If it has been predicted earlier, the Covid virus has started evolving differently. Compared with the first two years of the pandemic when variants seemed to appear out of nowhere, Tulio de Oliveira, a bioinformatician at Stellenbosch University in South Africa, who had detected the emergence of BA.4 and BA.5, pointed out new waves of coronavirus are periodically emerging from already circulating strains, for example, Omicron.

However, experts warned “we shouldn’t rule out more such surprises from SARS-CoV-2." Within six months since its emergence, the Omicron coronavirus variant evolved with several subvariants and currently, two new offshoots - BA.4 and BA.5 that are once again driving a surge in COVID-19 cases.

Studies BA.4 and BA.5 — are slightly more transmissible than earlier forms of Omicron1, and can dodge some of the immune protection conferred by previous infection and vaccination.

Great white shark stalking the East Coast spotted near New Jersey, Carolinas
FOX NEWS - A massive great white shark stalking the East Coast was spotted near the Carolinas on Monday after earlier being tracked off the coast of New Jersey, according to researchers.Ironbound, the 12-foot, 4-inch shark weighing nearly 1,000 pounds, made headlines after migrating from the Carolinas up the coast to New Jersey late last month.As of Monday, it appears the great white returned to the Carolinas, according to OCEARCH shark researchers who keep track of sharks’ migratory patterns via a tag tracking system.Researchers believe a white shark mating site is located off the Carolinas, the Boston Herald reported.OCEARCH Chief Scientist Robert Hueter told the outlet last week that Ironbound may have left the site early ahead of the other sharks, adding that is unclear what sparked the migration.Despite Ironbound’s apparent return to southern waters, New Jersey may not have seen the last of the great white. Hueter said that the sharks will usually start migrating to northern waters in mid-to-late May and arrive in those areas beginning in June.Ironbound is considered the "leader of the pack," according to Hueter, who described the apex predator as "formidable" and "not the prettiest animal."Ironbound was first tagged in October 2019 near Lunenburg, Nova Scotia.

City of Hamilton ends COVID-19 emergency declaration
Fred Eisenberger has ended the city’s COVID-19 emergency declaration.The action was first declared in unison with Ontario’s state of emergency enacted on March 17, 2020, as the coronavirus pandemic first began.A temporary order under the Emergency Management and Civil Protection Act (EMCPA) allowed municipalities the flexibility to deploy staff where they were needed to manage the city’s vital services.Eisenberger said the measure was “not rescinded lightly” by the city and that the community still needs to be “aware and be vigilant” as it eases into a “normal state.”The change means the city will return to in-person meetings, also offered in a hybrid format, on May 25 with committee meetings coming back on the week of May 30.City advisory committees will also return the week of May 30 while full-on advisory committees will still be limited as staff work through the process of a full return. Ontario COVID numbers: 1,555 people in hospital, 188 in intensive care The city’s mask mandate for its employees will also be lifted on May 25 with in-person public engagement allowed on the same day.“I do want to recognize the importance of this moment,” Eisenberger said in a virtual media conference on Tuesday. “It’s taken us two and half years to get here.”Public health epidemiologist Michelle Baird characterized the community’s current COVID situation as better having past the peak of transmission in the most recent wave.Case numbers, the percentage of PCR tests coming back positive and wastewater signals continue to show declines in spread of COVID.“Although transmission is decreasing, we are still in a pandemic,” said Baird.“But we are now in a phase where we are learning collectively what it means to live with COVID.
