2020: the year of living cautiously

2020 was the year when microbiology burst onto the world stage, not just as the science of small living things, but as the prism through which we understood global events. Clinical logic suffered under pressure arising from an urgent need to confirm or exclude severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This is a generation's Hobbesian moment in which the public concern for safety and security from infection outweighs the pursuit of personal freedom. The strangeness of a world in which a minute particle wields superhuman power has generated its list of unlikely heroes and mendacious villains. As the year comes to an end, there are glimmers of light amid the gloom: the prospect of an effective vaccine, and life after the pandemic.
