Could be, in fact I hope so. The quote, which was on the BBC, stated:
"Monday's data shows there were 1,205 new infections diagnosed, but surveillance suggests the true figure may be five times higher."
Alas, surveillance in its purest form refers to close observation so perhaps could refer to it being scrutinised, however the normal connotation is much darker.
We know that China and Israel to name a few have used such measures to monitor the progress of the virus, therefore it does raise questions about its reference.
