Rethinking Pandemic Strategies: Regular Testing and Self-Isolation Can Outperform Lockdowns

A new study suggests that regular diagnostic testing and self-isolation might be more efficient in handling transmittable diseases like COVID-19 than large-scale closures such as schools and organizations. The study, which includes the principle of “superspreading,” shows that an optimized method of random testing integrated with voluntary self-isolation can offer higher net advantages throughout various conditions, especially when compared to physical distancing mandates.
A new study from the University of Wyoming suggests that regular diagnostic screening and self-isolation might be more reliable than closing down schools and organizations in the battle against contagious illness like COVID-19.
The findings were recently released in the journal Scientific Reports.
The research was carried out by professors members of the UW Department of Economics– Stephen Newbold, David Finnoff, Jason Shogren, and Linda Thunstrom, and current Ph.D. graduate Madison Ashworth. The group devised an epidemiological and economic model to examine the efficiency of physical distancing requireds compared to policies that promote routine testing and self-isolation in the face of a blossoming pandemic. They found that a strategy of random testing tends to be more effective than physical distancing in a lot of circumstances when it pertains to alleviating the effect of COVID-19 or similar illness.

” The United States at first attempted to fight the spread of (COVID-19) using a portfolio of controls that is heavy on physical distancing and masks and light on regular diagnostic testing with self-isolation,” the researchers wrote, noting that the previous included work-from-home requirements, school and business closures, and travel restrictions. “However, these exact same steps also have actually caused lowered work, lost profits, and a variety of adverse physical and psychological health effects due to withdrawing from financial activities and curtailing social interactions for long durations.”
While a variety of scientists and public health experts have actually carried out studies suggesting testing and self-isolation would be more efficient than massive shutdowns, the UW research study is the very first to consider the idea of “superspreading”– in which a big share of people are exposed to a pathogen by a small number of infected individuals.
The UW scientists likewise used a wide array of model variations looking at both economic benefits and costs, and health outcomes, of the 2 methods to combating an illness outbreak. The research study took into account diagnostic test mistake rates, self-isolation compliance rates, the expense of testing, and lost financial productivity from physical distancing or isolation.
The researchers acknowledge that there is no clear response to whether federal government policy in the event of a break out need to focus on suppressing the disease through aggressive actions or slowing the spread through less aggressive procedures– obviously subtle differences can cause one technique performing much better than the other in any offered case.
The primary ramifications of the study, nevertheless, centered on the relative efficiency of physical distancing vs. testing.
” We discovered that for an epidemic comparable to the ancestral pressure of SARS-CoV-2, an enhanced strategy of random screening with voluntary self-isolation can deliver higher net benefits than a physical distancing method over a wide variety of possible conditions in our model,” the economic experts wrote, adding that integrating the principle of superspreading makes the testing-isolation method even more effective than physical-distancing requireds.

The team devised an epidemiological and financial design to assess the effectiveness of physical distancing requireds compared to policies that promote routine screening and self-isolation in the face of a blossoming pandemic. They found that a method of random testing tends to be more effective than physical distancing in most situations when it comes to mitigating the effect of COVID-19 or comparable illness.
