Recent research by the government in the UK has found that two million people are affected by long COVID. This article discusses what long COVID is, what the symptoms are, and how it is diagnosed and treated. This article also discusses how the National Health Service (NHS) plans to treat people using ‘long COVID out-patient clinics.’ Long COVID is becoming a significant public health crisis in the UK, and in the rest of the world. Long COVID has affected people in every part of society; it has affected the rich and the poor, although it has affected the poor in greater numbers than the rich. The budgetary implications of attempting to treat two million people for this disease are discussed, as are the implications of not treating people with long COVID.
