Query: Optimal periodic closure for minimizing risk in emerging disease
  outbreaks   Without vaccines and treatments, societies must rely on non-pharmaceutical
intervention strategies to control the spread of emerging diseases such as
COVID-19. Though complete lockdown is epidemiologically effective, because it
eliminates infectious contacts, it comes with significant costs. Several recent
studies have suggested that a plausible compromise strategy for minimizing
epidemic risk is periodic closure, in which populations oscillate between
wide-spread social restrictions and relaxation. However, no underlying theory
has been proposed to predict and explain optimal closure periods as a function
of epidemiological and social parameters. In this work we develop such an
analytical theory for SEIR-like model diseases, showing how characteristic
closure periods emerge that minimize the total outbreak, and increase
predictably with the reproductive number and incubation periods of a disease,
as long as both are within predictable limits. Using our approach we
demonstrate a sweet-spot effect in which optimal periodic closure is maximally
effective for diseases with similar incubation and recovery periods. Our
results compare well to numerical simulations, including in COVID-19 models
where infectivity and recovery show significant variability.
