The cycle is similar for most mild cases of the disease: patients become infected and, after a few days, develop symptoms flu-like symptoms that progress to a temporary loss of smell and taste. After a few days in quarantine, when the virus is no longer transmitted to others, the patient is ready to be discharged.

In short, you are released from isolation and can return to normal life, now free from Covid-19.
According to the Congress of the Radiological Society of North America, there are neurological effects of the disease that last for up to six months, so care must be taken. Learn about abnormalities in the brains of recovered patients.
Patients' brains and complications
To compose the study that gave rise to the thesis presented at the scientific congress organized by the Radiological Society of North America, in the United States, two groups of studies were created. One was made up of 46 recovered Covid-19 patients while the other had 30 patients who had never been infected with the virus.
Brain imaging was performed on each of these volunteers using a specific type of magnetic resonance imaging. It was possible to observe fundamental differences from which scientists draw some conclusions. See what was raised in debate.
Differences between brain scans
Patients recovered from Covid-19 had higher susceptibility values in the frontal lobe and brainstem. When looking at the frontal lobe clusters, what stands out are the gross differences in the white matter of healthy brains and brains with sequelae from the virus.
There are also differences in the right ventral diencephalon region of the brainstem, the area of the brain that commands and assists functions essential for the functioning of the entire human system, such as coordinating the endocrine system for hormone release and relaying motor and sensory signals to the cerebral cortex.
These changes were noticed in the brains of individuals affected by the disease for at least six months prior to the study.
What are the consequences?
Scholars believe that these brain changes are closely related to fatigue, insomnia, depression, headaches and cognitive problems.
These symptoms are often linked to what doctors they call it “long Covid”, that is, characteristics of the disease that remain after the period of transmissibility has ended.
