The absence of documented cases in China and other Asian countries that had already experienced a COVID-19 epidemic led to conjectures regarding the possibility of a significant evolution of the virus, or variations in susceptibility in different populations. On 2 June, news emerged of a first case of MIS-C diagnosed in Peru. In Brazil, cases of MIS-C have been reported in São Paulo, and in the context of a prospective study in Pará; more children with severe late manifestations of COVID-19 were being admitted to paediatric intensive care units in the region. In Chile, 42 confirmed cases of MIS-C had been recorded nationally by June 28, including 27 in the capital, Santiago. In Russia, 13 children had been treated (5 with intensive care) by mid-June for a multisystem inflammatory syndrome at the Morozov Childrens Hospital in Moscow, including a 2-year-old girl with the COVID-19 infection who died on 23 May following an initial diagnosis of suspected Kawasaki disease. In Iran, a case report (first submitted in May) described severe MIS-C in a 5-year-old girl who had presented with shock and was initially diagnosed with Kawasaki disease, and further cases of the new syndrome have been recorded. In India, a case of suspected MIS-C was reported in late May regarding a child who had presented in a COVID-19 hotspot in Kerala.
