Since political officials are trying to censor CDC reports, I thought I'd share 12 of the ones I've found useful:

1. Children of all ages are susceptible to SARS-CoV-2. Of ~600 attendees in this Georgia Camp, 44% tested positive. Median age was 12. 1/12

2. SARS-CoV-2 is stable in air: once airborne, SARS-CoV-2 retains ability to infect cells for at least 16 hrs. It's hardier in aerosols than SARS-1 or MERS. This helps explain why airborne route could be major culprit 2/12

3. Testing asymptomatic people is really important. This report on prisons shows that limiting tests to just symptomatic people underestimated cases by 12 times 3/12

4. Going to restaurants can be risky. This study of patients shows that those who tested positive for COVID19 were actually 2X more likely to have dined at a restaurant in the last two weeks 4/12

5. Young children contract SARS-CoV-2 and spread it to households. This study of childcare facilities uncovered 12 children who acquired the virus and passed it onto 26% of their non-facility contacts, including family members 5/12

6. We need more testing. Infections in health workers often go undetected: in participants who had contracted the virus, about half didn't know they'd previously had COVID19, and two out of three didn't even have a prior positive test result.

7. Air Travel can be risky: even though a passenger on this flight wore an N95 mask most of the time, she was infected during the flight. She was seated 3 rows away from an asymptomatic patient and took off her mask when using the bathroom 7/12

8. Virus is very contagious: of 3,635 meat facility employees, 929 (26%) tested positive. And that's an under-estimation of all cases since testing was directed at symptomatic people. An additional 210 of their contacts were also infected w/SARS-CoV-2 8/12

9. Coronavirus is in the air: 94 employees (out of 216) were infected in a call center in South Korea, a 43.5% attack rate! Nearly all of them sat on the same side of the building, suggesting airflow as culprit 9/12

10. Another study pointing to coronavirus in the air: an asymptomatic individual sitting at a table in a restaurant infected people sitting at two other tables that were facing an Air Conditioning unit, pointing to recirculated air as the culprit 10/12

11. Masks should be encouraged: Two hair stylists who were COVID-19 positive interacted with 139 clients. Everyone was wearing masks. 67 clients agreed to be tested and none of them were infected 11/12

12. young adults are not immune: of 508 hospitalized patients in this early study, 20% were aged 20–44 ,18% were 45–54 years, 17% were 55–64 years. Almost half of those in ICU were under 65 12/12
