The Sars-Cov-2 virus can manifest in very different ways, one of which is skin lesions. These may appear differently depending on the patient and the seriousness of the illness. In particular, they were described during the first wave, in patients hospitalised due to COVID-19. 

Man with skin blemishes

The most frequent skin reaction, which was observed in practically 50% of patients admitted to hospital due to COVID during the first wave, was exanthema, a rash or generalised erythema. In other words, skin manifestations in the form of red spots that may partially or totally affect the skin, and which may cause itching.  

Hand with chilblains

Another symptom presented by some COVID patients was chilblains. These are red or purple lesions which are often painful, and primarily appear on the fingers and toes. They are less frequent than exanthema, but because they are more noticeable and bothersome, they are one of the better-known symptoms. They occur in approximately 20% of patients.  

Person with pimples

Some people with COVID-19 have also presented urticaria in the form of generalised wheals or hives. They appear on different parts of the body and, like any other kind of urticaria, disappear in less than 24 hours.  

Hand with vesicles

Meanwhile, the appearance of vesicles, a type of very small blister, has also been observed in some patients. These are quite typical in certain viral infections. These lesions were less frequent, only being described in 9% of patients.  

Legs with varicose veins and spots on the calves

Finally, some patients have presented necrosis or Livedo reticularis, lesions caused by the inflammation of the skin’s most superficial veins. However, this symptom has been observed less frequently than the previous ones (6%).
