None of these recommendations are perfect, but the more of them you implement, the lower the chance of catching or passing on the virus. If we all do our best, we may be able to reduce risk and reduce the harm of COVID-19 on ourselves, our families, our friends and our communities. We can also reduce the risk of super-spreading events (like the Argyle nightclub in Newcastle) and help start 2022 with much less COVID than we might otherwise have.
