The coronavirus symptom that can help doctors predict the worst cases has been found, according to a team of researchers. The public has been warned that in the days to come, doctors may have to make some difficult choices about which coronavirus patients will be prioritised for treatment.
But it’s still very hard to predict who will develop the most severe Covid-19 infections. One clue, according to researchers at New York University, is a deep muscle ache.
Taken together with increases in the levels of haemoglobin, the protein that carries oxygen through the blood and ALT, an enzyme that doctors use to predict liver disease, myalgia – severe muscle aches – forms a tell-tale trio of symptoms.
