#SouthKorea has done a fantastic job with #ContactTracing This article analyzed reports for 59,073 contacts of 5,706 #COVID19 index patients. I believe it has important info for decision making related to #SchoolReopening

- Of 10,592 household contacts, 11.8% had #COVID19
- Of 48, 481 nonhousehold contact, 1.9% had #COVID19
- All contacts were monitored for an avg 9.9 days after #SARSCoV2 was detected
- In houses with index 10-19 y.o, 18.6% of contacts had #COVID19

Conclusion
- Rates were higher for contacts of children than adults
- Reports from other countries estimate secondary attack rate for close contact ~ 35%
-High infection rate within family, so use personal protective measures should be used at home to reduce risk of transmission

- Highest COVID-19 rate (18.6%) for household contacts of school-aged children and lowest (5.3%) for household contacts of kids 0-9
- School closure and distancing reduced rate of COVID-19 among contacts of school aged kids

What does this mean?
- I believe this further supports that we need to have low rates of community transmission before we consider opening up schools
- Per this data kids 10-19 had highest rates of contacts with #COVID19
- This is scientific data, let this lead our decision
