- Study by Hong Kong and mainland China researchers finds that more than half of the patients did not have a fever when admitted to hospital
In a joint study published in the New England Journal of Medicine, researchers from mainland China and Hong Kong reviewed the cases of 1,099 coronavirus patients from 552 hospitals in 30 provinces.
They found that more than half the patients did not have a fever when they went into hospital, making diagnosis more difficult. But 88.7 per cent of them did develop one after admission.
