Britain. Covid-19 The main symptoms are fever, cough, fatigue and loss of sense of taste and smell. Symptoms of Kovid-19 have also been seen in the skin. But there is another part of the body where the virus has an effect and that is your nails. Following a COVID-19 infection, some patients may have discoloration or change in shape several weeks later – this is called “Covid nails”. One symptom is the formation of a red crescent moon at the base of the nails. It appears to have been present before other nail complaints associated with COVID, with patients having seen it less than two weeks after being diagnosed with a COVID infection. There have been many cases – but not many.
This type of red crescent-moon shape on the nail is generally rare, and has not been seen so close to the base of the nail before. Therefore, this appearance of this shape can be a sign of infection especially of Kovid-19. One possible reason why this crescent forms on the nail could be damage to a blood vessel associated with the virus. Or it could be due to an immune response against the virus causing tiny blood clots to form and discoloration of the nail. Importantly, these marks are nothing to worry about if the patient is asymptomatic – although it is not clear how long they last. In the reported cases, it was a week in some and four weeks in some. Signs of physical stress Some patients also noticed new, distinct lines at the base of the fingernails of their hands and toes, which usually appear four weeks or more after COVID-19 infection.
These lines usually occur when there is a temporary blockage in nail growth due to some form of physical stress, such as infection, malnutrition or the side effects of chemotherapy. Now it can also be due to Kovid-19. Nails grow between 2 mm and 5 mm on average each month, with these lines becoming noticeable four to five weeks after physical stress – becoming visible as the nail grows. So the timing of the stressful event can be estimated by looking at how far these lines are from the base of the nail. There is no specific treatment for these lines, as they tend to get better once the problem is resolved. Currently, the available evidence suggests that there is no association between the severity of the COVID-19 infection and the type or time frame of nail changes. Other unusual findings The above facts are linked to two common nail changes due to COVID infection, but the researchers also recorded some other unusual events.
A female patient’s nails loosened from the base and eventually fell off three months after her infection. This phenomenon is known as onychomadesis. This patient did not receive treatment for these changes, yet new nails could be seen growing under the nails that were lost due to the disease, indicating that the problem had started to resolve on its own. Another patient was tested 112 days after being found infected with an orange mark on his nails. No treatment was given for this and even after a month the scar had not diminished. The underlying reason behind this is unknown. In the third case, white lines appeared on the nails of a patient. These are known as mease lines or transverse leukonychia. She appeared 45 days after the confirmation of the infection of Kovid-19.
These heal as nails grow and do not require treatment. Although we are seeing nail changes in all of these three conditions as being associated with infection with COVID-19, we have a small number of patients in each case, so it is not possible to say that they were due to the disease. It is entirely possible that all three have nothing to do with this situation. In fact, there is still a long way to go to confirm such symptoms are definitely linked to the symptoms of Kovid-19. We will need many more cases for this. It is important to remember that not all patients with COVID-19 will have this nail condition. And some of these abnormalities may not mean that someone has got COVID-19. Better yet, we should consider these as possible symptoms of a past infection – and not definitive evidence.
