In March 2020, the first cases of COVID-19 were reported in the St. Louis region, and health officials in St. Louis County and the city of St. Louis issued emergency orders to try to halt the virus’ spread. A new study from researchers at Washington University School of Medicine in St. Louis determined that those orders may have saved hundreds of lives and prevented thousands of hospitalizations. An analysis conducted by infectious diseases specialist Elvin H. Geng, MD, a professor of medicine, indicates that had the orders been delayed by as little as two weeks, the number of deaths in the city and county could have increased almost sevenfold. Geng says it’s important to be proactive and do whatever possible to stop a virus’ spread, especially in the early days of a pandemic. Over time, restrictions may become more reactive to a given scenario, in response to peaks in the spread of infection. Now confronted with the highly infectious delta variant, public health officials again have been considering stricter measures to slow the number of infections, hospitalizations and deaths.
