More than 235 million people have been infected with coronavirus in the world. This shows the severity of the pandemic that has affected an important part of the planet.
Many people who were infected with SARS-CoV-2, have referred to the persistence of some symptoms, even months after having overcome the disease.
It is the long covid (or persistent COVID-19), which has recently been recognized by the World Health Organization (WHO).
This term, which until recently was not recognized by the medical community, refers to the fact that some of the symptoms suffered by patients can last for several months.
The WHO notes that patients can experience symptoms months after the initial infection and that they can become so severe as to affect their daily functioning.
The long covid was an expression that, at first, the infected themselves coined. For this reason, many questions remain, such as the frequency with which it occurs and the other symptoms that can be associated with it.
This week, the WHO published its definition on prolonged covid, which is necessary for medical studies on it.
According to the agency, long covid occurs in people with a history of probable or confirmed infection by SARS-CoV-2, usually three months after the beginning of the original case.
These symptoms include fatigue, shortness of breath, and cognitive dysfunction, also known as brain fog.
“This definition of the post-COVID-19 condition will help advance both advocacy and investigation, but will likely change as new evidence emerges and our understanding of the consequences of COVID-19 continues to evolve,” say experts from the WHO.
