Nearly half of Americans who are hospitalized due to COVID-19 may have mild cases or may be asymptomatic, a new study suggests.

Researchers looked at patients admitted to medical canters within the healthcare system of the Department of Veterans Affairs (VA) since the start of the pandemic.

Public health experts have previously stated that hospitalizations are the metric that best defines how well the U.S. is doing against COVID-19.

According to the Department of Health and Human Services, 96,870 virus patients are occupying hospital beds across the country, the highest figure seen since February 2021.

But researchers say the figure does not reveal how many in the hospital are severely ill and how many just happened to discover they have COVID-19 while hospitalized. 

For the study, published on Monday on pre-print site Research Square, the team looked at
