The illness started with fever of 38.0°C, of three days of evolution accompanied by arthralgias, myalgias, retro ocular pain and uterine contractions. The patient was admitted to the intensive care unit due to respiratory failure (which required invasive mechanical ventilation), acute renal and hematologic failure, following cesarean section. She required surgical reintervention for intra-abdominal bleeding due to coagulation disorders.
