UCLA Researchers Say Physical-Distancing Measures, if Relaxed Too Soon, Might be All for Naught
Study highlights dangers of COVID-19 spike after removal of health precautions
If physical-distancing measures in the United States are relaxed while there is still no COVID-19 vaccine or treatment and when personal protective equipment remains in short supply, the number of resulting infections could be about the same as if distancing had never been implemented to begin with, according to a UCLA-led team of mathematicians and scientists.
The researchers compared the results of three related mathematical models of disease transmission that they used to analyze data emerging from local and national governments, including one that measures the dynamic reproduction number — the average number of susceptible people infected by one previously infected person. The models all highlight the dangers of relaxing public health measures too soon.
Bertozzi is also a distinguished professor of mechanical and aerospace engineering. Elisa Franco, a UCLA associate professor of mechanical and aerospace engineering and bioengineering, is one of the study co-authors.
