When the pandemic that we still live in began, one of the specialists’ difficulties was to understand the consequences of the passage of COVID-19 through the patient system. This is because, being a new infection, there was not yet enough information to support any conclusions.

Today, more than a year after the first case in the world appeared, there is already more scope for evaluation and, therefore, for conclusions.


COVID-19: “We are just beginning to understand”

As we know, the symptoms associated with COVID-19 are, mostly and more commonly, fever, dry cough and fatigue. However, the possible permanence of these symptoms was not yet a certainty in the medium-long term, as well as the occurrence of others, due to the lack of infection.

Because COVID-19 is such a new disease, we are just beginning to understand some of its long-term effects on patients' health.

Said Bin Cao the National Center for Respiratory Medicine and lead author of the study.

So, to understand it, studies were emerging. Among them one that was published in the medical journal The Lancet and involved 1,733 patients who were discharged from Jinyintan Hospital in the Chinese city of Wuhan. In fact, it is among the few investigations that have traced the long-term symptoms of the COVID-19 infection.

On the one hand, they found that fatigue and muscle weakness were the most common symptoms, with some even having difficulty sleeping. On the other hand, the researchers found that 76% of people hospitalized between January and May 2020 still suffered from at least one symptom after 6 months without the infection.

Unknown long-term effects of COVID-19

According to the World Health Organization, for some people, the virus may pose a risk of serious ongoing effects. In fact, not neglecting young and once healthy people.

In addition to physical examinations and laboratory tests, researchers questioned respondents about their symptoms and quality of life, based on health. Then, 63% of those once infected recognized fatigue and muscle weakness. While 26% revealed sleep difficulties.

Possibility of reinfection

In addition to the symptom study, the researchers looked at 94 patients whose blood antibody levels were recorded at the height of their infection. After being subjected to a new test, after 6 months, their levels of neutralizing antibodies were 52.5% lower.

Therefore, the researchers reiterated that this reality may raise concerns about the possibility of reinfection by COVID-19. However, more samples and a larger study are needed to clarify whether the virus's immunity changes over time.
