HANTAVIRUS PULMONARY SYNDROME IN THE PROVINCE OF RIO NEGRO, ARGENTINA, 1993-1996
Open accessAbstract
Early in 1995 the first case of Hantavirus Pulmonary Syndrome was serologically confirmed in El Bolsón (Province of Río Negro, Argentina), corresponding to the third outbreak reported in Argentina. A total of 26 cases of HPS related to the Andean region of Rio Negro Province, were reported from 1993 to 1996, 17 in El Bolsón, 4 in San Carlos de Bariloche, and 5 in Buenos Aires. The incidence rate was 5.03 x 100000 with a mortality rate of 51.85 x 100. The occurrence of cases was mainly seasonal, with a significantly greater number in the spring, and the persons affected mainly lived in urban or periurban areas. In four cases, the affected individuals were members of a couple, spouses or live-in contacts. Seven cases were Health workers (physicians, nurses or administrative staff). Twelve cases were related among them, due to an outbreak of 80 days. Two of them did not visit the Andean region. A total of 139 rodents were captured and seven of them, Olygoryzomys longicaudatus, were found to be serologically positive. The possibility of infection by contact with rodents or fecal matter is being analyzed and also hypothesis related with interhuman transmission

These noncomparative studies are not able to make causal inferences and are limited to a few outbreaks, and the findings of some outbreaks have been published across different reports with some inconsistencies.
“However, as noted above, these studies are not able to make causal inferences and are limited to a few outbreaks, and the findings of some outbreaks have been published across different reports, with some inconsistencies in the accounts (see, eg, Supplementary File 4 [6–8, 28]).”
From Evidence for Human-to-Human Transmission of Hantavirus: A Systematic Review (2022) · cites this paper as [28]
The Objectives (p. 2) describe a study of cases in Río Negro that aimed to develop a hypothesis about transmission, and the Discussion (p. 5) calls for case-control and genomic studies to evaluate transmission better. This supports the limitation on causal inference for this outbreak study. Our copy does not establish that accounts of the outbreaks were published across different reports or that those accounts were inconsistent. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
