Large events are cancelled, restaurants and non-essential businesses are closed, and in many states, residents have been asked to shelter in place, all to limit the spread and impact of the COVID-19 virus.
Large events are cancelled, restaurants and non-essential businesses are closed, and in many states, residents have been asked to shelter in place, all to limit the spread and impact of the COVID-19 virus. But are strict and early isolation and other preventative mandates really effective in minimizing the spread and impact of a disease outbreak?
Stefan E. Pambuccian, MD, a Loyola Medicine cytologist, surgical pathologist and professor and vice chair of the Department of Pathology and Laboratory Medicine at Loyola University Chicago Stritch School of Medicine, has reviewed published data and research from three papers dating back to the 1918-19 Spanish flu pandemic, which infected one-fifth to one-third of the world’s population and killed 50 million people.
According to the data and analysis, cities that adopted early, broad isolation and prevention measures—closing of schools and churches, banning of mass gatherings, mandated mask wearing, case isolation and disinfection/hygiene measures—had lower disease and mortality rates. These cities included San Francisco, St. Louis, Milwaukee and Kansas City, which collectively had 30% to 50% lower disease and mortality rates than cities that enacted fewer and later restrictions. One analysis showed that these cities also had greater delays in reaching peak mortality, and the duration of these measures correlated with a reduced total mortality burden.
