Health experts are warning Australians to prepare for a challenging winter as cases of COVID-19, influenza, and RSV surge across the country. Professor Paul Griffin emphasized the urgency of getting vaccinated before the end of May to minimize risk, especially for vulnerable populations like the elderly and immunocompromised. He noted that infections are spreading rapidly within households, making early prevention critical.

Australia has already recorded over 80,000 confirmed flu cases as of May 22—a 50% jump from the same period last year. Influenza, particularly types A and B, remains highly contagious and poses a serious health risk. At the same time, COVID-19 infections are expected to rise with the emergence of a new Omicron subvariant, LP.8.1, which is responsible for 60% of recent cases in the UK and is spreading globally.

Though LP.8.1 does not appear to cause more severe illness than previous strains, its high transmissibility raises concerns about increasing infection rates. Health officials are urging Australians to get both flu and COVID-19 vaccines promptly to help prevent severe outcomes and reduce hospital admissions.

Experts warn that without widespread vaccination and preparedness, the combination of these respiratory viruses could overwhelm healthcare systems during the colder months. Early action is seen as the best defense against what could be a particularly severe winter season.
