Recently, some unusual warning signs have joined the list of possible symptoms of the coronavirus. A study of more than 60,000 people who tested positive for the disease showed that a small percentage had problems such as hairy tongue, purple fingers, and skin rashes. A larger analysis of more than 600,000 people in the UK showed that a small portion of those infected with Covid-19 also developed purple sores and blisters on their feet, as well as numbness all over their bodies, among other problems.
says d. . Bernardo Almeida, Master of Infectious Diseases at UFPR (Federal University of Paraná) and Medical Director of HELLAB.
The expert points out that no matter how rare the symptoms are, their occurrence may increase with the increase in the number of disease cases as well. “For example, a symptom that occurs in 0.1% of cases will only occur 10 times if the number of cases is 10,000. On the other hand, if there are 10 million cases in the world, then these symptoms will appear in 10,000 cases, and it may become a problem with a greater impact. , although they are relatively rare,” he explains. Some people experience ringing in the ears, eye sores, skin irritation, a red rash on the face or lips, hair loss, and unusual joint pain.
Strange symptoms – the expert points out that no matter how rare the symptom is, its incidence may increase as the number of cases of the disease also increases. “For example, a symptom that occurs in 0.1% of cases will only occur 10 times if the number of cases is 10,000. On the other hand, if there are 10 million cases in the world, then these symptoms will appear in 10,000 cases, and it may become a problem with a greater impact. , despite the relative rarity of their occurrence, ”he explains.
Five unusual symptoms of Covid-19:
hairy tongue
Also called hairy tongue, it is a condition associated with a change in the normal exchange pattern of cells in the buccal mucosa, which build up, leaving the tongue with a different appearance than usual. The good news is that this condition only lasts a few weeks, and returns to normal in the vast majority of cases. The doctor reassures.
Tingling in the nerves
The doctor explains that this symptom indicates viral or immune system action in the peripheral nervous system. “It can even lead to nerve pain, similar to what happens with herpes zoster. Frame accuracy is the norm after a few weeks. If persistent, a neurologist’s evaluation is recommended,” he says.
skin irritation
So-called rashes occur in many viral diseases, many of which are very common in childhood, and they can affect adults as well. “The main mechanisms are viral action and/or immune reaction. Usually, it is a mild presentation that improves spontaneously, but in more severe or long-term cases, evaluation by a dermatologist is recommended.”
hair loss
Hair strands have a lifespan and fall out naturally after the end of the cycle. In usual cases, new hairs emerge at a rate that maintains the total amount of hair. However, several factors can affect this life cycle, such as disease or stressors, which eventually cause several hairs to end their life cycle at the same time, which leads to a temporary increase in the rate of hair loss. In Covid-19, these two factors (illness and stress) are likely to contribute to these symptoms, which tend to normalize as new hair grows. Bernardo.
Purple, sore, or painful toes
There is no consensus regarding these symptoms, which are also called “Covid toes.” “They can be caused by microthrombosis in the small vessels of the fingers, but this is just a theory, it hasn’t been proven yet. Fortunately, they get better with time, and in more severe cases, some topical medications can be used to alleviate the symptoms,” he says.
