the lesions that also appear to those who are negative on the test


Findings about the effects of Covid-19 on the body are multiplying. Among the possible manifestations of the disease, also the so-called ‘Covid toes’, or skin lesions that manifest themselves with red sores or damage to the feet (and hands) of children and young adults. Now a new study published in the British Journal of Dermatology provides evidence to support the link between these lesions and Covid-19.

In most cases, those affected are negative for swabs or serological tests, but the Spanish researchers who authored this study found that the SARS-CoV-2 it is present in the skin biopsies of children with typical ‘Covid toes’ lesions, despite the negative results of the tests to discover the coronavirus. The analyzes revealed the virus in the endothelial cells of the blood vessels of the skin and in the sweat glands. Electron microscopy thanks to a biopsy also identified viral particles inside the endothelial cells.

“Our results support a causal relationship between Sars-Cov-2 and the ‘toes from Covid’. Virus-induced endothelial damage could be the key mechanism causing these injuries, “said lead study author Isabel Colmenero of the Hospital Infantil Universitario Niño Jesús, Spain.” In addition, vascular damage could also explain some features clinics observed in patients with severe Covid-19 “.
