How to know if the fatigue you feel is a symptom of coronavirus or something else

The numbers of infections by coronavirus do not stop growing and our search for new ones symptoms and signs to suspect that we are infected, neither. So much so that it is not difficult to find comparisons of coronavirus and cold and flu symptoms throughout the internet. Science is also responsible for awakening our most hypochondriacal instincts because it knows more and more about the coronavirus and shares with us new symptoms of Covid (in the eyes, on the skin) and new consequences of said infection. The last one is the confirmation of several scientific publications that post-covid fatigue exists (according to a study published in the Journal of the American Medical Association 87% of discharged patients suffer at least one symptom two months after infection and in more than half of the cases that symptom is extreme fatigue). So can fatigue be a red flag for people who don't have any other symptoms? Let's see what the data says.

How to know if fatigue is a symptom of Covid-19

The most common symptom in people who develop COVID-19 infection is fever. The second symptom, the cough. And the third, fatigue. It is not strange that this is so, after all that feeling of not being able with our soul is quite common in all kinds of infections and the culprits of the mess are substances called cytokines. These small proteins are responsible for waking up our immune system but, unfortunately, they have the side effect of leaving us to drag.

How can we distinguish if our fatigue is motivated by the fight against infection or because we have spent two months chaining blank nights? First, because the fatigue caused by the coronavirus does not usually seem alone. The most common is that it appears accompanied by other symptoms and those other symptoms are the most varied, they are not just fever and cough.

You may have neither fever nor cough, but start the infection with tiredness and a sore throat, or tiredness and muscle aches, or tiredness and frequent visits to the bathroom, for example. Always keep in mind that coronavirus can infect all types of cells, from those of your intestine to the nervous ones, that is why it is capable of causing such a variety of symptoms.

A separate case is that of people who have already passed the infection but, months later, are still exhausted. This phenomenon has recently been described in an article published in the scientific journal Plos One with a sad conclusion: women have twice the risk of suffering from this problem than men, especially those who have had a history of anxiety.
