Long Covid . . the successor to 'Post-viral Fatigue', which has been around for years.

Covid 19 is obviously worse than a bad bout of the flu and has probably affected more people (the Flu figures have been lower) which gives a higher incident rate of Post-viral Fatigue, but it's nothing new.

Despite the word “fatigue”, the symptoms can be broader and more debilitating than simple tiredness. They can include a sore throat, aches and pains across the body, blood pressure changes, gastric upsets such as irritable bowel syndrome, headaches, sleep disturbance, depression, and dizziness. More severe neurological symptoms can also occur, including new sensitivities or allergic reactions, and burning or prickling sensations in the limbs. Many COVID-19 patients, for example, report a prolonged loss of smell and taste.

One of the earliest outbreaks recorded was in 1934 in California, where people infected with an unknown virus (thought to be polio) experienced “bursting headaches”, aching limbs and muscle weakness for a prolonged period. Other episodes were recorded in Iceland in 1948, and in Adelaide in 1949.

a UK study in August estimated 10% of those with COVID-19 go on to develop post-viral symptoms.

This is not necessarily surprising, given research on other similar viruses. One Canadian study found 21 health-care workers from Toronto had post-viral symptoms for up to three years after catching SARS in 2003, and were unable to return to their usual work.

A 2006 Australian study examined 253 people from Dubbo after they caught infections including glandular fever, Q fever, and Ross River virus. It found 11% of cases went on to develop chronic post-viral symptoms that lasted at least six months.
