How frequently should students in a college community get tested in order to prevent large COVID-19 outbreaks?

Reopening School Testing and Contact Tracing

A: Every 2 days, according to one recently-published model. Every 2 days!? Whaaaaah???? With hundreds of thousands of students around the country headed back to college campuses this month, COVID testing is something every college needs to plan for: Who, how, and how often? The “how often” question was answered last week in a study

What is pool testing?

Testing and Contact Tracing

The benefit is that it can facilitate an increase in testing capabilities as well as result in cost/resource savings (when supplies are low). This is not a new strategy to test individuals for infectious

How does contact tracing work again? With states reopening, how is that component of the test-trace-isolate strategy going so far?

Testing and Contact Tracing

A. Well…there are challenges. Contact tracing is a tried and true public health measure that’s been successfully used to contain other infectious diseases (e.g measles, HIV, food poisoning outbreaks, etc). Indeed, the CDC has indicated that it is a necessary precursor for easing lockdown restrictions. The uploaded graphic illustrates the steps in the process. However,

I don’t currently have any symptoms, but I want to visit older family members soon, so I went and got a PCR test for COVID-19 (i.e., the kind that detects *current* infection). My test came back negative, so I am in the clear, right?

Socializing Testing and Contact Tracing

After you are exposed to SARS-CoV-2, the amount of virus in your body builds up over time, reaching its highest level, right before symptom onset. It can take 2-14 days (average of 5-6) from
