MADRID (MarketWatch) -- A second case of Ebola may have been detected in Madrid on Tuesday, a spokesman for the Ministry of Health told El Mundo newspaper. Like the first victim announced on Monday, the second victim was part of a medical team treating two now deceased victims of Ebola: a Spanish priest, Miguel Pajares, and missionary Manuel García Viejo. Media reports said the second victim is in isolation at Hospital Carlos III, along with the first medical worker and her husband. The European Union sent a letter Monday to the Spanish health minister to inquire as to how the first medical worker contracted the deadly disease, said media reports.
