As Victoria recorded a coronavirus milestone with no active cases, another virus is sweeping through Melbourne’s suburbs.

While it is nowhere near as serious as COVID-19, the virus is making life difficult for many families and can be dangerous for the young and elderly.

Respiratory syncytial virus (RSV) produces a number of the same symptoms as the common cold, including respiratory distress, runny nose, cough and fever.

Mum Kellie Conlon said RSV left her three children in hospital, including her four-month-old daughter.

“They had her on high-flow oxygen and she was screaming for the entire night,” Conlon told 7NEWS.

RSV is running rampant across Melbourne, largely due to social distancing for the past year weakening the immune system.

“Now that people, particularly kids, are back in circulation again so are the viruses that we normally see around winter time,” Dr Stephen Parnis from the University of Melbourne said.

The elderly are also at risk.

Dr Caroline Bartolo said the advice to avoid contracting and spreading RSV is to wash hands often and stay home when feeling unwell.

Those with sick children should also keep them home.
