MIT Medical has worked with each positive case to identify any close contacts. Close contacts are defined as individuals who spent more than 15 minutes cumulatively within six feet of a person who tested positive for COVID-19, from two days before illness onset or, for asymptomatic people, two days prior to positive COVID-19 test. All unvaccinated close contacts have been advised to quarantine by MIT Medical.
