Coronavirus
A Look at How the Pandemic Has Changed After Two Years
How has the COVID-19 pandemic changed after two years?
More countries are shifting toward a return to normal and learning to live with the virus. Safe, effective vaccines have been developed and there’s better understanding of how to treat people sickened by the virus.
Two years after the pandemic began, questions remain about the coronavirus. But experts know a lot more about how to keep it under control.
The virus mainly spreads through the air when an infected person exhales, talks, coughs or sneezes. It’s why health officials have encouraged the use of masks and ventilating spaces, instead of focusing on advice to wipe down surfaces as they did early on.
