Two papers testing reinfection with SARS-CoV-2 in rhesus macacques. They both show minimal viral load after reinfection.
This suggests that reinfection may not be a concern.
Obligatory "this is not in humans" and "I am not a virologist" and "these are small sample sizes". But these are optimistic preliminary results, for sure
Viral load after initial infection was found in various tissues. However, in the re-infected group, viral load was not detected in any of the same tissues.
This suggests the infection and re-infection were both done properly and that the virus was cleared and no longer present, even after re-infection
All 3 groups showed a reduced viral load after re-infection. It was still present in the high and medium exposure groups 1 day after re-infection, but not detectable in the low-exposure group.
Viral load was not detected after 6 days in all 3 exposure groups. These levels were all much higher in the initial infection
