A study by the Australian National University (ANU) has found that long COVID is affecting up to 20% of Australians three months after they contracted COVID-19. The condition, characterized by lasting symptoms and inability to work or provide care for family members, is disproportionately affecting women and children.
The impact of long COVID on individuals and society is significant. A recent study estimated that the cost of lost labor from a single round of infections in 2022 would be $9.6 billion, with hundreds of thousands of Australians affected.
Long COVID can be divided into three groups: those with damaged lungs, those with lingering coughs, and those with mysterious symptoms, including chronic fatigue syndrome (CFS). The exact cause of long COVID is still unknown, but researchers have proposed two basic theories: viral persistence and the “hit-and-run” theory. If proven correct, this could lead to new treatments for the condition.
Research suggests that vaccination can reduce the risk of developing long COVID, and a recent study by the Burnet Institute found evidence supporting the viral persistence theory. The institute argues that viruses persist in the body after an acute infection, which could explain many of the problems associated with long COVID, including fatigue and brain fog.
The discovery of SARS-nCov-2 hiding in immune cells has provided new insights into the cause of long COVID. If confirmed, this would have significant implications for treatment and prevention strategies. The fact that long COVID is not infectious after the acute phase sets it apart from other chronic diseases, such as HIV/AIDS and polio.
The study’s findings highlight the need for further research into the causes and treatments of long COVID. As the pandemic continues to evolve, it is essential to stay informed and engaged in the conversation about this critical public health issue.
