It depends on whether your state and local officials are making evidence-based decisions and have the resources (testing, contact tracing, isolation) to implement a containment strategy after reopening. Right now we are in mitigation. If we reopen gyms, schools, and businesses, we will end up in one of two situations: 1) containment, including widespread testing, contact tracing for all confirmed infections, and isolation of exposed persons to restrict the spread of the virus and prevent a resurgence; OR 2) unbridled spread of the virus. Which of these alternatives comes to fruition depends on many variables, including production and distribution of testing supplies.
A government decision to reopen gyms would be a necessary, but not sufficient, condition for me to send my child back. Until our state implements a robust containment strategy that includes widespread testing, contact tracing, and isolation, AND there are very few confirmed infections, our family will be staying in no matter what the governor says.
