Only 27% of Colorado residents who tested positive for SARS-CoV-2 prior to the March 26 stay-at-home order reported a known contact with a confirmed COVID-19 case, another 30% had contact with a person with fever or respiratory symptoms, and the remaining 43% reported no known contacts.

A seroprevalence survey from six US states and regions found seroprevalence in serum collected for routine clinical purposes ranged from 1.1% to 7.9%. The authors concluded that in five out of the six US sites, there have been >10-times more SARS-CoV-2 infections than cases reported.

Based on the experience of 4 European countries, there is some evidence that school closures led to declines in the epidemic growth rates of COVID-19. Reopening of schools for all students in countries with low community transmission (Denmark and Norway) has not resulted in a significant increase in the growth rate of COVID-19 cases. Return of most students to school in countries with higher levels of community transmission (Germany) has been accompanied by increased transmission among students, but not school staff.

A genome-wide association study identified two separate loci associated with genetic susceptibility to severe COVID-19 disease. One of the loci coincides with the ABO blood group locus. The genetic results found blood group O was associated with lower risk of COVID-19 while blood group A was associated with higher risk of severe disease.
