Coronavirus has been the absolute protagonist of our reality for almost a year now. Every day, we are aware of the number of infected people, deaths, new discoveries and vaccine processes.
It is impossible to go a whole day without hearing about the virus that has changed our lives. And with the restrictions and contagions, our daily lives have been completely affected.
Despite all the information about coronavirus and its symptoms, you might have had coronavirus without even knowing or you may have thought it was just another seasonal flu.
For the past few months, persistent COVID (or long COVID) has been under investigation and we keep getting more and more information about it. These are symptoms that resist over time or may reappear after the patient has recovered.
As we have been able to discover in 20minutos, research published by JAMA Network Open has published a study analyzing the long-term symptoms that people who have already had coronavirus may have.
In the study, conducted by researchers at the University of Washington, more than 30% of participants had persistent symptoms for up to nine months after contracting COVID-19. This overall percentage increases to 43.3% for those over 65 years old.
According to the study, in addition to being one of the most common symptoms, it is also one of the most persistent: Fatigue, loss of taste and smell appeared in 13.6% of the participants who had persistent symptoms.
As reported by the U.S. Centers for Disease Control and Prevention (CDC), "Even people who are not hospitalized and have a mild illness may have persistent or delayed symptoms," and they also note that "studies are ongoing and will take several years to investigate further."
For their part, 13% explained for the study that they had suffered mental confusion. As reported by the Spanish media 20minutos, Dr. Allison Navis (Icahn School of Medicine at Mount Sinai Hospital in New York) explained that this is a symptom, but not a diagnosis and that it does not affect everyone equally: "it is often a combination of problems with short-term memory, concentration or difficulty in expressing oneself".
This symptom was observed, above all, in young, healthy people who had a mild case of coronavirus. But this is not the only study focused on the symptoms of long COVID, there are many more.
In fact, in one conducted in Wuhan, more than 1,700 coronavirus patients were analyzed and, of them, 76% presented a symptom months after supposedly overcoming the virus. In addition to fatigue in 63%, 23% had difficulty sleeping.
In addition to these symptoms, anxiety and depression are also reported as psychological sequelae. In fact, the U.S. Centers for Disease Control and Prevention (CDC) points out that depression is one of the persistent symptoms due to COVID.
The CDC highlights, on its website, which long-term symptoms are frequently reported:
CDC also talks about other symptoms that, while not as common as the ones above, are also reported:
For its part, the CDC also highlights more serious complications that may occur in the long term but are less common. The Centers for Disease Control and Prevention explains that "it is not yet known what these long-term effects entail."
