Health authorities "cannot rule out" the possibility of a "missing link" in Melbourne, after four new COVID-19 cases were reported in the Victorian capital.

"Given the proximity of the gentleman from early May who returned from hotel quarantine in Adelaide who lives in that city, we do not rule out the prospect that there is a link," Health Minister Martin Foley told reporters this afternoon.

"The dates do not line up immediately so we cannot rule out if there is a missing link out there.

"In terms of this gentleman's infectious period being from May 18 and the fact that our original hotel quarantine case from Adelaide was well and truly in hotel quarantine in Victoria during that period, they do not cross over in that period in terms of incubation and they do not appear, that is, to cross over."
