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.
