Transmissible for longer?
in the Transmission Dynamics attached below, transmissibility is shown at a peak even before symptom onset, but subsiding by 8 days, but reports today, suggest this could be much longer
In addition, care home residents are testing positive for Covid-19 more than 30 days after showing first symptoms – 38 days in one case. It may be that the tests are picking up dead virus cells, but the discovery is causing uncertainty about how long people who have had the virus might remain capable of transmitting it.

December 2021
this transmission curve has been updated (thx James Hay for this)
but for symptomatics the peak transmission is still before and at about symptom onset? while of course for asymptomatics, they're happily going about as usual.. unless there are strong proceedures in place
