Is there a reason to think that at a diluted level it wouldn't, in a dormant state, be any worse than say the herpes virus?
A question not a hyphothesis

Al Jazeera has a good article here:

Pertinent parts:
Research on the Middle Eastern Respiratory Syndrome (MERS) virus has shown that immunity wanes after around 18 months and we build an average of two years' immunity to the Severe Acute Respiratory Syndrome (SARS) coronavirus, which seems to have the most in common, genetically speaking, with COVID-19.
From what has been observed about COVID-19 so far, researchers suspect that we will have at least a "short-term" immunity, so that you will be unlikely to catch it again this season.
A scientific research team based in China released a preliminary report looking at two rhesus macaques that had recovered from COVID-19 and were not reinfected when researchers exposed them to the virus for a second time, four weeks after their initial exposure.

While we cannot rule out reactivation as a possibility yet, it still seems more probable that these 91 cases were either due to the levels of the virus dipping below a detectable level, allowing symptoms to improve, but then surging again, or that there were flaws with the tests, where the clearance samples were false negatives. The tests are not perfect and, from the data received from China, the most commonly used type of test showed up to a 30 percent false-negative rate.
