The disparity cannot be entirely explained by underlying health conditions, place of residence or place of care, according to the study published Tuesday in the journal PLOS Medicine. The team found that Black people were more likely to be tested than Hispanic and White people. Black people were tested at a rate of 60 per 1,000 people, compared to 52.7 per 1,000 among Hispanic people and 38.6 per 1,000 among White people. Among those who received Covid-19 tests, 10.2% of Black people and 11.4% of Hispanic people tested positive, compared to just 4.4% of White people.
