The new coronavirus is a killer with a crowbar, breaking and entering human cells with impunity. It hitchhikes across continents carried on coughs and careless hands, driven by its own urgent necessity to survive.
It has a gregarious side that makes it hard to resist. It loves a party. The persistent social climber claims its victims around the world by riding on moments of the most innocent of human interactions—a shared laugh, a conversation, an embrace. And it is a liar. SARS-CoV-2, which causes Covid-19, often misleads the body’s immune systems.
Taken on its own terms, SARS-CoV-2 is the infectious disease success of the past 100 years.
