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.
Treatment has also evolved for people who get sick or need to be hospitalized. Among the options are antivirals, such as the drug remdesivir, or newer pills from Pfizer and Merck; anti-inflammatory drugs including steroids; and depending on what variant is circulating, lab-made antibodies to attack the virus.
