Covid cases are beginning to climb again in NSW. You can see here where it's mostly happening - in kids, in schools. On the 'herd immunity' front, people need to know that infection with Covid confers relatively little ongoing immunity, many people have had 2 or 3 infections overseas in the past year. Often the second infection is even more serious than the first. And then some get 'Long Covid', which is poorly understood but potentially may create lifelong morbidity.
