Over the past period, infection with the Corona virus has been associated with an increased risk of blood clots. According to a recent study, infection with the Corona virus increases the risk of developing dangerous blood clots and bleeding for months afterwards.
According to the study, and as published in webmdCorona virus infection is a risk factor in itself that increases the risk of hemorrhage, pulmonary thrombosis and deep vein thrombosis. In this study, the researchers stress the importance of people who are considered more vulnerable to these cases to adhere to their treatments and the importance of receiving the vaccine in the face of the Corona virus.
It is true that this relationship between infection with the Corona virus and the risk of blood clots was known, but what was not clear was how long this risk could last. Therefore, the researchers compared a total of one million people in Sweden who contracted the virus at different stages between February 2020 and May 2021, compared to a comparison group of 4 million people who did not contract the virus. It was found that people who contracted the virus were significantly more likely to develop deep vein thrombosis and thrombosis in the feet for up to 3 months after infection, pulmonary thrombosis for up to 6 months, and for bleeding up to 2 months.
As a result of the study, researchers discovered that those infected with the Corona virus were 5 times more likely to develop deep vein thrombosis and 33 times more likely to develop pulmonary thrombosis. The risk of bleeding within 30 days of infection with the virus increases twice as much.
Deep vein thrombosis has been observed in 0.04 percent of corona patients. And 0.17 percent of patients developed pulmonary thrombosis and 0.10 of patients had hemorrhage. However, the risks of blood clots were more important for patients whose conditions were serious when infected with the virus and who were exposed to its complications, and for patients who suffer from other health problems and who contracted the virus in the first wave more than those who contracted the infection in the second or third wave. The reason, according to the researchers, may be the improvement in vaccination levels and treatments during the second and third waves.
But in all cases, it became clear that even patients who had mild cases were more likely to develop deep vein thrombosis and pulmonary thrombosis, while there was no increase in the risk of bleeding in those who had mild corona.
Thus, despite the lifting of restrictions in many countries of the world in the face of the Corona virus, this study calls for more caution in confronting the virus and its dangerous complications, especially blood clots, even if the condition is mild when infected with the virus.
