The #COVID19 data problem in Switzerland. As @sbonhoeffer says, we need to analyse #ContactTracing data to look at where coronavirus is, but they still aren’t available... 1/n

The point is to have info to break transmission chains. Showing that families account for a large proportion of #COVID19 is one thing. But it doesn’t show the source of infection. Where did the family member get infected? #ContactTracing should joint the dots... 2/n
No identifiable #COVID19 source outside the family is a warning ⚠️ That means #CommunityTransmission not controlled. And that means we need to #TestTestTest to find infections, then #TestTraceIsolateQuarantine to stop transmission ...3/n
...and that’s another conundrum. Why are #SARSCoV2 testing numbers so low? Testing is our friend. Testing is a tool to help #CaseFinding in community and in contacts. Testing finds pre-symptomatic infectious people so they can be isolated and not transmit further 4/5
And, to close the loop, data from #ContactTracing tell us about #TransmissionChains and #Outcomes to show us where we are doing well, where we need to improve. This is #PublicHealth. So endeth the sermon 5/5
