Chilblains like lesions (CLL) are the most common cutaneous manifestation of covid 19. These tend to usually occur in the Caucasian paediatric population / young adults. Quite baffling is the associated fact that the majority of these patients test PCR negative to covid. These young patients tend to produce a very early onset copious amount of interferon 1 IgA subtype which essentially defeats the virus very early on, thus preventing detectable levels of antibodies to be built up subsequently. Immunofixation finds these IFN - 1 deposits in covid toes. These are thus now thought to be due to a combination of endothelial dysfunction and immune mediated response "activation loop" following covid 19 infection.
