Vigilância da influenza A (H1N1), novo subtipo viral, no Estado de São Paulo, 2009
Bibliographic record
Abstract
During April, 2009, a new viral subtype of the influenza A(H1N1 ) virus was identified in clinical specimens collected from two patients in the United States. The same viral strain was identified in Mexico, Canada and other parts of the world. This event was considered, by the World Health Organization (WHO) as a Public Health Emergency of international Concern. The present study describes the occurrence of notified influenza A(H1N1) cases of the new viral subtype, to the Epidemiologic Surveillance Center of the State of São Paulo, during the period comprised between April 22 to May 21, 2009, according to their distribution in time and space, as well as age groups and gender affected, finishing with the final case classification and criteria employed. A perfected surveillance was implemented, based on the Influenza Pandemic Preparedness Plan of the State of São Paulo, regarding timely identification and investigation of the cases. Respiratory samples were processed in the Instituto Adolfo Lutz, employing, as method of choice, real time chain polimerase reaction (rRT-PCR). A total of 87 reported cases, distributed, in the majority, in Greater São Paulo were concentrated in the age group of 20 to 49 year olds (70,1%), and coming from areas with confirmed cases of influenza A(H1N1). The most frequent symptoms were fever and cough (100%), and mialgia (70,1%); 40,2% were admitted to the hospital, all of them discharged with symptom remission. It is important to enhance the need to maintain the alert of the health systems regarding early detection and rapid response to cases and adoption of adequate prevention and control measures, as well as issuing information for both health professionals and the population regarding the present situation of this event.

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.
