Earlier, the Ministry of Health announced that a fourth victim died of pneumonia of unknown origin on Saturday in Tucumán, northwestern Argentina.

“We are talking about a 48-year-old patient with concomitant diseases who was in a serious condition in a communal hospital,” the Ministry of Health reported.

This is the fourth death in less than a week, with two employees of a private clinic in San Miguel de Tucuman dying on Monday and then on Wednesday. A 70-year-old woman, a patient of the same clinic where she was operated on, died on Thursday.

According to the ministry, a total of 11 people have developed similar symptoms and seven are still undergoing treatment. Of the ten initially registered cases, eight were medical workers of one private clinic.

Samples sent for analysis revealed cases of “legionellosis,” a serious lung infection caused by a bacterium called Legionella, local newspaper La Gaceta reported Saturday, citing sources at the Malbran Institute in Buenos Aires, where in-depth research is being conducted.
