While reported Covid cases across Victoria increased by 18 per cent last week, in Bass Coast the increase was 42.5 per cent.
Local case numbers are back to their highest level since January.
Health authorities said data showed 80 per cent of patients that presented to hospital in April who had received at least one prior Covid vaccination, had not had a vaccination in the past six months.
“This indicates most people who presented to hospital are under-immunised,” the Chief Health Officer’s weekly report stated.
It said 4.3 million Victorians are currently eligible for a 2023 booster dose.
People are urged to continue to protect themselves by wearing a mask and getting vaccinated.
You can book a free booster appointment through your local GP or pharmacy. You can find your nearest vaccination provider through the Health Direct Service Finder at healthdirect.gov.au
