A protester who attended the anti-vaccination demonstrations in Melbourne’s CBD on Wednesday is in hospital with COVID-19.

The Department of Health has confirmed the news on Thursday evening.

The person is not receiving intensive care.

A full public health investigation is underway.

Anybody who attended the rally is being urged to get tested, especially if they experience COVID-like symptoms (no matter how mild).

It comes after Victoria recorded its highest ever daily case number.

Ambulance Victoria chief Tony Walker told 3AW on Thursday afternoon emergency services had never been under so much pressure.
