Fully opening restaurants and not having mask rules in place and the Centers for Disease Control (CDC) warned.
“This report is a critical reminder that with the current levels of COVID-19 in communities and the continued spread of more transmissible virus variants, which have now been detected in 48 states, strictly following prevention measures remains essential for putting an end to this pandemic,” said CDC director Rochelle Walensky, MD, at a White House COVID briefing on Friday. “It also serves as a warning about prematurely lifting these prevention measures.”
Dr Walensky’s comments may have been made with states such as Texas and Mississippi in mind, with their governors announcing that they were dropping mask mandates and allowing full reopening, including businesses such as restaurants at full capacity. Some restaurants that are still enforcing
Research has already shown that in-person dining and lack of mask regulations contribute to the spread of COVID cases. Taking data from state and local health department websites, COVID cases and deaths were analysed at county level The team compared data from post-implementation time points, ranging from 1-20 days to 81-100 days, to pre-implementation periods.
The researchers also attempted to control for other factors, such as restaurant closures during the mask mandates, mask mandates in the restaurant reopening models, stay-at-home orders, and bans on gatherings of more than 10 people.
Of the three-quarters of surveyed counties with mask mandates, the researchers found that within 1-20 days of mask mandates, there was a 0.5 percentage point drop in COVID case growth rates. Case and death growth rates saw almost a 2.0 percentage point decline 81-100 days after mask mandates came into effect.
Conversely, states allowed restaurants to re-open for in-person dining. While the impact was not immediate, COVID case growth rates increased 1.1 percentage points 81-100 days later. However, counties allowing in-person dining were associated with 2.2 percentage point increases at days 61-80 and a 3.0 percentage point increase at days 81-100 after restrictions were lifted.
The researchers speculated about the cause, such as restaurants potentially delaying reopening even after they were allowed to do so, and that patrons might have been more cautious during initial reopenings but more likely to dine at restaurants as time passed.
