COVID-19 has had a tremendous impact on the world, affecting millions of people globally. While many people recover from the virus in a few weeks, some people experience persistent symptoms that can last for several months after they have contracted COVID-19. This condition is known as ‘Long COVID,’ or Post-Acute Sequelae of SARS-CoV-2 Infection’ (PASC).
Studies of the occurrence of long COVID have only recently gathered momentum, however from the limited data available, current prevalence estimates of Long COVID (defined as >12 weeks) in Australia range from 5% to 10% of COVID-19 cases. This means that Long COVID is becoming increasingly common and may become a significant contributing factor to long-term disability for Australians.
The symptoms of Long COVID can vary widely, but common ones include fatigue, difficulty with memory and concentration (brain fog), shortness of breath, muscle and joint pain, and headaches. Some people also report heart palpitations, chest pain, and gastrointestinal symptoms. Experiencing any number of these symptoms on a persistent basis can significantly impact daily life and can make it challenging to return to work at a pre-illness capacity.
