Warning symptoms of Coronavirus

Warning symptoms of Coronavirus

Are there any symptoms or “warning signs” of the CODVID-19? We’ll find out together in this article.


Traditional symptoms

Type B patients usually present symptoms of fever, cough, headache, and a cold. They are roughly 10-20% of the total.
Type C patients, who are critically ill present a picture of respiratory failure, and are approximately 10-15% of the total. (This may vary due to the region’s data.)

Type A subjects, on the other hand, are the rest of the people infected with the Coronavirus, that is, the majority, who do not present particular symptoms. This percentage is likely to be between 60-80%.



The warning signs

Many have asked us if there are any particular symptoms to pay attention to, which may be a basis of “warning signs” of the COVID-19.



Conjunctivitis appears to be one of them. Reports of many patients with respiratory symptoms from the wards of medicine, infectious diseases, and pneumology show that conjunctivitis occurs before the respiratory symptoms themselves. If you currently have conjunctivitis, it is advisable not to underestimate it, report it to your doctor and request for a pharyngeal swab and rapid test.

The loss of smell and taste

The loss of smell and/or the sensation of loss of taste are two symptoms that have been reported to us by a large number of people who were then found positive for the pharyngeal swab for the coronavirus, and then for the specific rapid test. For some, it seems that this sensation is the first and only manifestation of mild symptoms, while for others it is a sensation that anticipates the fever. Reportedly, it lasts for about ten days and then returns along with other new symptoms. This phenomenon, which can affect up to 30% of those positive for the coronavirus test, was also noted by Claire Hopkins, the president of the British Rhinological Association. Recently, Prof. Galli del Sacco from Milan also found this symptom in many of his clients.


Muscle aches and asthenia

Muscle pain and asthenia without fever are other symptoms reported by my colleagues.
The onset of fever is 4-6 days
before these symptoms.



Some colleagues of mine reported that positive COVID-19 cases have had major dysentery as a symptom. Unfortunately, we do not know how many of those with dysentery are related to the coronavirus, because it would imply to swab all those who have dysentery. However, it is likely that a part of the rather frequent dysentery experienced during this period is due to the COVID-19.





Although they are absolutely partial and not yet confirmed by traditional scientific studies, we can say with good approximation that loss of smell, loss of taste and conjunctivitis can be initial and therefore premonitory symptoms of the COVID-19. Those who have these symptoms can report them to their family doctor and request a pharyngeal swab and rapid test. 


It can be of great help to stem the spread of the virus!

As for widespread pain and dysentery, we cannot yet identify them as warning symptoms or indicative of the COVID-19. It is appropriate to wait for further epidemiological evidence in this regard.
