Las gastroenteritis víricas: un problema de salud pública
Bibliographic record
Abstract
Acute gastroenteritis (AG), which may be caused by bacteria, parasites and enteropathogenic viruses, including rotaviruses, astroviruses, adenoviruses and caliciviruses, is an important health problem. The frequency of rotavirus as a cause of sporadic cases of AG ranges between 17.3% and 37.4%. Although it has been suggested that common exposure is not an important factor in the diffusion of rotavirus, it is difficult to associate apparently sporadic cases, meaning that there are probably outbreaks that go undetected. Astroviruses cause GA with a frequency ranging between 2 and 26%: outbreaks have been described in schools and kindergartens, but also in adults and the elderly. The frequency of identification of adenoviruses 40 and 41 as causes of sporadic AG in non-immunosuppressed children ranges between 0.7% and 31.5%, although there is probably underreporting because the sensitivity of conventional techniques is low. Caliciviruses are separated phylogenetically into two genera: Norovirus and sapovirus. Norovirus is frequently associated with food- and water-borne outbreaks of AG. It is estimated that 40% of cases of AG due to norovirus are foodborne. In Sweden and some regions of the United States, norovirus is the first cause of outbreaks of foodborne diseases. Sapovirus outbreaks due to person-to-person and foodborne transmission affecting both children and adults have recently been reported in countries such as Canada and Japan.

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
