The University of Washington epidemiologists who set up a widely watched model projecting the future course of the coronavirus outbreak have translated those projections into suggested time frames for loosening strict shelter-at-home orders across the country.

current expiration date for Gov. Jay Inslee’s “Stay Home, Stay Healthy” order . data-reactid=” “type=” text “> For Washington state, that time frame is the week of May 24, which is two weeks longer than the current expiration date for Gov . Jay Inslee’s “Stay Home, Stay Healthy” order

Based on the current projections from UW’s Institute for Health Metrics and Evaluation

, four states – Montana, Vermont, West Virginia and Hawaii – could loosen their restrictions as early as the week of May 4. Other states, ranging from Massachusetts and North Dakota to Arizona, may have to wait until the week of June 8 or later.

Those projected dates could shift, of course, depending on how the institute tweaks its models, which it’s done repeated over the past month. And in the end, it’s up to the nation’s governors, not researchers, to determine how strict their social distancing policies are.

The Institute for Health Metrics and Evaluation acknowledged that there are likely to be state-by-state variations in how restrictions are eased, just as there were state-by-state variations in the timing and extent of the shutdowns.

“ Each state is different, ”IHME Director Christopher Murray

said in a news release

. “Each state has a different public health system , and different capabilities. This is not a ‘one decision fits all’ situation. ” IHME based its projections for easing restrictions on the estimated time frame for seeing the COVID – infection rate fall below one new infection per million residents in a given state. The institute said that’s “a conservative estimate of the number of infections each location could rea sonably try to identify via active case detection and contact tracing in order to prevent COVID – 27 resurgence. ”

it’s likely to be more than a month

before those resources are sufficiently available. “data-reactid=” “type=” text “> The schedule comes with caveats: For example, its projections assume that states will have adequate resources for virus testing, contact tracing and isolation of infected people. Earlier this week, Seattle-area public health officials said it’s likely to be more than a month before those resources are sufficiently available.

Also, there’ll have to be continued restrictions on large gatherings. Earlier this month, Microsoft co-founder Bill Gates – whose foundation has been at the forefront of global health issues for years – said large gatherings might have to be ruled out

until a vaccine is available, which could take a year or more. Murray said the time frame for easing back restrictions is becoming clear er largely because the restrictions have been so effective. Computer modeling of mobility patterns, based on cellphone location data, suggests that social contact has declined more than expected, especially in the South. “We are seeing the numbers decline because some state and local governments, and equally important, individuals around the country have stepped up to protect their families, their neighbors, and friends and coworkers by reducing physical contact, ”Murray said.

Looking ahead, Murray said it’ll be important for public health officials to monitor the effects of an easing in restrictions. “Relaxing social distancing too soon carries great” risks of a resurgence of new infections, ”he said. “No one wants to see this vicious cycle repeating itself.”
