As winter settles in Australia, the country finds itself grappling with a unique challenge—a triple threat virus. The convergence of the flu, COVID-19 and the highly contagious Respiratory Syncytial Virus (RSV) has led to a surge in respiratory illnesses across the nation. With some states experiencing their worst flu seasons in decades, the added burden of RSV has health experts urging Australians to remain vigilant and get tested to protect themselves. This article highlights the impact of RSV, its symptoms, and the importance of a rapid test capable of detecting all three viruses.
Respiratory Syncytial Virus, more commonly known as RSV, has emerged as a significant concern during Australia's winter season. Typically circulating during this time, much like the flu, RSV has seen an alarming increase in reported cases compared to the previous year.
According to the Department of Health and Aged Care, some states are witnessing up to ten times the number of RSV cases, adding to the existing burden of influenza. Reports indicate that Queensland is already grappling with its worst flu season in decades, putting the entire country on track for a similarly severe influenza season as 2019—the largest on record in Australia.
Understanding RSV and its impact
RSV primarily affects young children, with most experiencing at least one infection before they turn two. Unfortunately, there is no cure or vaccine available for RSV, making it a common cause of hospitalisations among children during winter months in various parts of the world, including Australia.
The virus spreads easily among individuals through coughs and sneezes and can infect the airways and lungs. Common symptoms include a runny nose, cough, reduced feeding, and fever. While most people recover within a week or two, complications such as wheezing and breathing difficulties can arise, potentially leading to pneumonia.
Although it resembles a mild cold, the susceptibility of infants and older adults to severe infections is a concerning aspect of RSV. Infants in their first year of life are more vulnerable due to smaller airways and lack of immunity from previous exposures. As a result, RSV is recognised as a major cause of lung infections in children, commonly causing bronchiolitis (inflammation of the small airways in the lung).
