Covid from February 2020 to May 2021, with a control group of over four million who did not test positive. The researchers have found that those with Covid had a higher risk of pulmonary embolism-a blood clot that blocks arteries in the lungs, up to six months after infection.
Besides, the side effects of Covid-19 are also seen in the legs. The respiratory infection also increases the danger of "Deep Vein Thrombosiis"--which is blood clotting in the legs.
This usually lasts up to three months. People who suffered from severe Covid symptoms along with pre-existing health conditions were more at risk of blood clotting.
But even those who had mild cases, who did not need hospitalisation, had a higher danger of pulmonary embolism and deep vein thrombosis.
