Brazilian authorities Monday confirmed the detection of four cases of the JN 2.5 subvariant of the SARS-Cov-2 virus in the state of Mato Grosso. The patients were reported to be all female and hospitalized in a serious condition. One of them even died. However, the Mato Grosso State Health Department said there was no reason to panic because at this point “it is not possible to say that the cause of death was COVID-19” since ”the patient already had chronic obstructive pulmonary disease (COPD).”
