Medical experts studying coronavirus have discovered a new potential side effect of the virus that could be contributing to the number of people dying.
Doctors say up to 30 per cent of people who have fallen seriously ill with Covid-19 are developing blood clots.
Known as thrombosis, the BBC says reports show the blood could be clotting because of inflammation in the lungs caused by the body’s reaction to the virus.
Roopen Arya, professor of thrombosis and haemostasis at King’s College Hospital, London, said: “Some of the more recent studies show that nearly half the patients have pulmonary embolism or blood clot on the lungs.”
Thrombosis expert Prof Beverley Hunt told the BBC sticky blood is leading to higher rates of strokes and heart attacks – some fatal.
The blood thinners being used to treat the clots are not always working – and using too much can be fatal in itself.
Doctors around the world started seeing a far higher rate of blood clots in new patients in March and scans have shown hundreds of micro-clots in patients’ lungs.
There has also been an increase in Deep Vein Thrombosis (DVT).
Clots like this become deadly when pieces break off, travel through the body and block blood vessels.
