BOSTON (CBS) – A new study conducted at a grocery store in Boston looked at the COVID-19 risk that workers face.
In May, the study looked at 104 employees and found that 20% tested positive for the virus. However, three out of four workers who test positive have no symptoms. That means the worker is a significant source of disease without realizing it, the researchers say.
More than 16,000 grocery stores across the United States have been exposed or exposed since the pandemic began.
