This long-read blog updates what is known about long COVID – now informed by some very large studies and a meta-analysis. The two most concerning aspects of long COVID are its high prevalence (up to 30% of those infected) and, as reinfection is increasingly common, a dose-response relationship between the number of infections and the increased risk of harmful outcomes. Such findings reinforce the continuing need for government action and individual commitment to the core preventive measures of: vaccination, mask use inside public places, and physical distancing where possible.

The downstream damage can affect: brain, heart, lungs, pancreatic beta cells (resulting in diabetes), muscles, the immune system, eyes, kidneys, and erectile tissue. There is, to date, quite consistent evidence that vaccination is wholly or partly protective against long COVID, whether vaccination occurs before or after COVID-19. A society wanting to minimise the health and cost burden of managing long COVID would therefore choose to maximise vaccination coverage as well as minimise risk of infection with standard public health and social measures.
