According to a study by the American health authorities published on Tuesday, people who have had Covid-19 are twice as likely as others to subsequently develop a pulmonary embolism or respiratory problems.

This work also shows that among people aged 18 to 64 who have contracted Covid-19, one in five suffers from symptoms following their infection and which can be attributed to it.

Among those over 65, this figure rises to one in four.

This proportion corresponds to the results of past studies which have estimated that around 20 to 30% the number of former Covid-19 patients experiencing long-term symptoms, more commonly called long-term Covid.

In total, the appearance of 26 health concerns potentially linked to Covid-19 has been studied by the Centers for Disease Control and Prevention (CDC), from an extensive database of medical records in all countries. UNITED STATES.

Those over 65 particularly affected

The symptoms experienced by patients who had Covid-19 after their infection (more than 350,000 people) were compared to patients who did not have it, over a period from March 2020 to November 2021. Covid-19 were significantly more likely than the control group to develop pathologies that could be attributed to prior infection,” the CDC wrote.

The most common health concerns experienced were respiratory symptoms, as well as musculoskeletal pain.

In people over 65, all the health concerns studied were more likely to occur after a Covid-19 infection.

In adults under 65, the risk remained unchanged for only a few (mental health problems, cerebrovascular diseases, etc.).

For both groups, the risk was greatest for respiratory symptoms and pulmonary embolisms - blood clots blocking a pulmonary artery, which can be fatal.

“Routine evaluations of pathologies appearing after Covid-19 are crucial to reduce their incidence and impact, especially in people over 65,” the CDC wrote.

They point out that the study did not take into account the vaccination status of the patients, and was carried out before the variants currently in circulation appeared.
