A new study done by the National Institutes of Health is showing that in five states, some people were infected with Covid-19 before those states recorded their first cases. Blood samples collected between January and March of 2020 were tested for antibodies… out of 24,000 samples, nine came back positive. While these cases were earlier than previously recorded it does show that there wasn’t much community spread at the time. Betsy McKay, senior writer at the WSJ, joins us for more.
