LONDON (Reuters) - Ongoing illness after infection with COVID-19, sometimes called "long COVID", may not be one syndrome but possibly up to four causing a rollercoaster of symptoms affecting all parts of the body and mind, doctors said on Thursday.

In an initial report about long-term COVID-19, Britain's National Institute for Health Research (NIHR) said one common theme among ongoing COVID patients - some of whom are seven months or more into their illness - is that symptoms appear in one physiological area, such as the heart or lungs, only to abate and then arise again in a different area.
