The startling report comes amid a growing realization that Covid’s toll extends beyond the number of lives claimed directly by the disease to the excess deaths caused by illnesses left untreated and a surge in drug overdoses, as well as to social costs like educational setbacks and the loss of parents and caregivers.

Numerous reports have suggested that Americans drank more to cope with the stress of the pandemic. Binge drinking increased, as did emergency room visits for alcohol withdrawal. But the new report found that the number of alcohol-related deaths, including from liver disease and accidents, soared, rising to 99,017 in 2020, up from 78,927 the previous year — an increase of 25 percent in the number of deaths in one year.

That compares with an average annual increase of 3.6 percent in alcohol-related deaths between 1999 and 2019. Deaths started inching up in recent years, but increased only 5 percent between 2018 and 2019.
