The sixth victim was an 81-year-old man with comorbidities who was intubated in critical condition – All cases linked to a private clinic in San Miguel de Tucuman

The outbreak of Legionella pneumonia, centered on a clinic in Tucuman, northwestern Argentina, claimed two more lives on Sunday, bringing the death toll to six in a week, the provincial health ministry said.

The sixth victim was an 81-year-old man who had co-morbidities and was intubated in critical condition, the ministry explained in a press release.

Earlier yesterday, the ministry had announced the death of another patient, the fifth in a row, a 64-year-old man, also with co-morbidities. The day before Saturday, he had announced the death of the fourth patient, a 48-year-old man who also had underlying diseases.

A total of 11 people have shown symptoms and five are still being treated, both in hospitals, according to provincial health minister Luis Medina Cruz. All cases are linked to a private clinic in San Miguel de Tucuman, the provincial capital. They were recorded from August 18th.

Most of the patients were members of the nursing staff at the private clinic, while one patient was a 70-year-old who had undergone surgery there.

The agent that caused the bilateral pneumonia “is Legionella,” Argentina’s Health Minister Carla Vicotti said Saturday during a press conference in Tucuman, adding that the effort to identify its exact strain is ongoing.

Initial tests ruled out COVID, influenza, influenza A and B, Hantavirus (s.b.: transmitted by rodents), and dozens of other germs as the cause of bilateral pneumonia.

Samples were sent to be urgently analyzed by the national reference laboratory, the Malbran Institute in Buenos Aires; Health Minister Vicotti presented the initial results of the analyses.

Legionella is a serious lung infection of bacterial origin. Infection can occur through the respiratory tract, by inhaling the bacterium, “through water or air conditioning,” Ms. Vicotti recalled.

He added that “measures are being taken at the clinic to ascertain whether (the bacteria) is in the water and in the collection tank” so that the clinic can be “used again without any risk”.

The president of the medical school of the province of Tucuman, Hector Salle, underlined in his statements last week that the pathology observed was “aggressive”, but it is not a priori a disease transmitted from person to person, given that “close contacts of these patients do not present any symptoms”.
