As Australia continues to record thousands of new COVID cases daily, officials are warning that Omicron subvariants are proving to be pesky… BA.4/BA.5 are set to become the major strains in our big cities before too long. Authorities say they don’t believe there’s any difference in disease severity, but it is likely to increase cases and hospital admissions. “This is because the strain has a greater ability than BA.2 to evade immunity provided by vaccination and earlier COVID-19 infection,” said Victorian Chief Health Officer Brett Sutton. As we head into the guts of winter, medicos have asked those eligible for a booster to get it. And they have told people with symptoms to stay at home because it’s not OK to get a negative RAT test and head out saying “Oh, it’s not COVID, it’s not the flu. I’m OK to be around people,” said the Australian Medical Association’s Queensland president Maria Boultan.
