Advocates are calling for rapid government action to protect Victorians living with disability as the number of coronavirus infections linked to the state's care sector ticks past 100.
There are 56 infections in state government-funded transfer homes and one in a standard disability home, according to government figures released on Wednesday.
A further 20 residential clients and 61 staff members have also contracted the virus.
Australian Federation of Disability Organisations chief executive Ross Joyce said the number of infections was a growing concern.
"People living with disabilities are very vulnerable [to COVID-19], due to their underlying health conditions," Mr Joyce told SBS News.
"We are deeply concerned about people living in congregate settings such as aged care.
"When [COVID-19] first started, they weren't allowed any visitors and weren't allowed to connect with their circle of support."
Mr Joyce said the lack of contact was a worry.
"It leaves people with disabilities very vulnerable, especially in an enclosed environment where they may be left open to abuse or neglect or exploitation," he said.
"Individual advocates are not allowed access to those premises as they are not treated as a worker, visitor or a priority role ... even support workers can't get in, in a lot of cases."
Victorian Premier Daniel Andrews said the government was taking steps to coordinate the state's response to the outbreak. AAP
He also expressed concern about people with disability who are working within Australian Disability Enterprises (ADE's).
"A lot of people with intellectual disabilities are still working in ADE's packing and sorting," Mr Joyce said.
"We don't think any ADE should be operating and we think it's imperative on management to really seriously look at the health and safety requirements of their workers.
"All people with disabilities should be at home with online support."
Mr Joyce - who provided primary health care during the 2009 swine flu epidemic - said he was "quite amazed at the lack of understanding and training on infection control."
"10 years later we haven't learned lessons from the swine flu experience," he said.
"Even knowing how to put on masks properly and when to dispose of them or how to clean."
"It needs to be part of a thorough induction for everyone working [in the sector] to understand the risk."
Women with Disabilities Victoria chief executive Leah Van Poppel said there is a "strong sense of caution and concern" about the potential for further outbreaks in group homes.
"That's a concern because they are closed environments and there's challenges about staffing in those environments," she told SBS News.
"If someone is really routine-bound or has particular access requirements it is difficult to move them around."
With self-isolation a major safeguard against the virus, Ms Van Poppel is also worried about a lack of accountability.
"As we become less visible, there might be a rise in violence toward people with disability," she said.
"It's not just the risk of the virus and its complications, but also the increased risk of violence because more people living with disabilities might not have a choice about how isolated they are.
"It's difficult to have people visit and check-in and we know particularly women with disability report a higher rate of violence than men with a disability."
Premier Daniel Andrews says a government partnership has been set up to coordinate the state's measures in the disability care sector, similar to steps taken in aged care.
"Any cases amongst vulnerable groups are concerning but I think it's important to note it is a really important partnership and one that has served us and will continue to when it comes to those settings," he said.
