In fact, the initial analysis of self-reported data sent through the Covid Symptom Study App suggests that 13% of people who experience Covid-19 symptoms have them for more than 28 days, while 4% have symptoms after more than 56 days.
Perhaps unsurprisingly, people with a more severe illness initially, characterized by more than five symptoms, appear to be at increased risk for prolonged Covid. Older age and female gender also appear to be risk factors for prolonged symptoms, as well as having a higher body mass index.
Those who use the app tend to be on the fittest end of the population, interested in health matters. It is therefore surprising that such a high proportion have symptoms one to two months after the initial infection. Generally, these are not very vulnerable to Covid-19.
Another piece of early research (awaiting peer review) suggests that SARS-CoV-2 might also have a long-term impact on people’s organs. But the profile of those affected in this study is different from that of those who reported symptoms through the application.
This research, which analyzed a sample of 200 patients who had recovered from Covid-19, found mild organ impairment in 32% of people’s hearts, 33% of lungs, and 12% of kidneys. of people. Multiple organ damage was found in 25% of patients.
The patients in this study had a mean age of 44 years, making them an important part of the young population of working age. Only 18% had been hospitalized with Covid-19, which means that organ damage can occur even after a non-serious infection. Having a disease that is known to lead to more serious Covid-19, such as type 2 diabetes and Ischemic heart disease was also not a prerequisite for organ damage.
Finding out what’s going on
There are many reasons why people may have symptoms months after a viral illness during a pandemic. But getting to the bottom of what goes on inside people will be easier for some parts of the body than others.
