Medical professionals have been looking for ways to distinguish COVID-19 cases from similar and other respiratory diseases since the beginning of a deadly virus outbreak. Many of them help identify signs that can indicate whether a patient might have a coronavirus infection or suffer from another disease.
Symptoms of the Corona virus
Although it is now common knowledge that the typical symptoms of COVID-19 infection are high temperature and cough, the same is true for other diseases such as the common cold and seasonal flu. In some cases, even severe allergies have the same symptoms. Until now, the best way to find out whether someone has or does not have a coronavirus infection is by undergoing a COVID-19 test.
However, health experts in Spain think they might have discovered other early symptoms of coronavirus infection and that is something that is not present in other respiratory diseases. The researchers found that some COVID-19 patients there had begun to develop small, but clearly visible, lesions at the bottom of their limbs.
According to health experts, lesions can be present even in confirmed COVID-19 which has no other symptoms. They say that the cause of the lesion is unknown but they heal themselves. Spanish doctors say this new discovery can help medical professionals detect new cases of COVID-19 infection.
Detection is a major challenge
A statement was issued by the General Board of Spain’s Official Podiatric College explaining the details of this unusual phenomenon. The statement translated in Spanish reads, “It is a purple lesion (very similar to chicken pox, measles or chilblains) which usually appears on the toe and usually heals without leaving a mark.”
Deciding who is infected with COVID-19 has become a major challenge for medical professionals. Health experts also believe that a deadly virus can be transmitted from one person to another even without symptoms. With the discovery of lesions in the legs, doctors now have a different way of finding positive cases.
Possible Alarm Bell
According to European doctors, lesions are easily seen and are quickly found. They also disappear and recover completely after a few days without the necessary medical intervention. Spanish health experts began calling this lesion a new COVID-19 infection alarm bell, or in other words, a red flag on the lower leg. Doctors say there is currently no indication that the lesion might be dangerous. If they can use it to detect cases of COVID-19 early on, it can be a big boost for them.
However, European health experts are unclear about how common these symptoms are among COVID-19 patients but that confirms these lesions have been observed in many European COVID-19 cases. The researchers also said that they still need additional data and more cases to establish a link between this deadly virus and this strange symptom.
