According to a Swedish study, contracting Covid-19 increases the risk of serious blood clots, up to six months after infection.

A new long-term consequence of Covid-19? According to one swedish study published this Wednesday, April 6, 2022 in the British Medical JournalCovid-19 would increase the risk of deep vein thrombosis (a blood clot in the leg) up to three months after infection, pulmonary embolism (a blood clot in the lungs) up to six months after and a bleeding event up to two months later.

And we already knew that the Covid-19 favored the risk, it was not known over how long these risks were increased and whether it had evolved according to the different waves of the pandemic. According to the researchers, the risk would also be higher in patients with comorbidities or those who have experienced a severe form of the disease.

They also note that the risks of thrombosis and pulmonary embolism were greater during the first wave, in March 2020, compared to the second and third waves. An explanation which can be found in the subsequent improvements in treatments against Covid-19 and especially by the much higher vaccination coverage of the oldest patients.

The importance of vaccination to prevent clots from forming

To arrive at their results, the researchers identified more than a million people have contracted Covid-19 between 1e February 2020 and May 25, 2021. They were thus associated by age, sex and place of residence with more than four million people who had never had Covid-19. Rates of deep vein thrombosis, pulmonary embolism and bleeding were calculated and compared to the control group.

And for the researchers, these results show first of all the importance of taking measures, in particular with regard to thegiving treatments that prevent clots from forming in the blood vessels to people who are most at risk, and finally reinforce the importance of vaccination against Covid-19.
