In the Philippines, an effective surveillance system is crucial for managing diverse infectious diseases. The Newcomb-Benford Law (NBL) is a statistical tool known for anomaly detection in various datasets, including those in public health.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Using Philippine epidemiological data from 2019 to 2023, this study applied NBL analysis. Diseases included acute flaccid paralysis, diphtheria, measles, rubella, neonatal tetanus, pertussis, chikungunya, dengue, leptospirosis and others. The analysis involved Chi-square tests, Mantissa Arc tests, Mean Absolute Deviation (MAD) and Distortion Factor calculations.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Most diseases exhibited nonconformity to NBL, except for measles. MAD consistently indicated nonconformity, highlighting potential anomalies. Rabies consistently showed substantial deviations, while leptospirosis exhibited closer alignment, especially in 2021. Annual variations in disease deviations were notable, with acute meningitis encephalitis syndrome in 2019 and influenza-like illness in 2023 having the highest deviations.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>The study provides practical insights for improving Philippine public health surveillance. Despite some diseases showing conformity, deviations suggest data quality issues. Enhancing the PIDSR, especially in diseases with consistent nonconformity, is crucial for accurate monitoring and response. The NBL\u2019s versatility across diverse domains emphasizes its utility for ensuring data integrity and quality assurance.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/pubmed\/fdae062","type":"journal-article","created":{"date-parts":[[2024,5,2]],"date-time":"2024-05-02T07:28:06Z","timestamp":1714634886000},"page":"e483-e493","source":"Crossref","is-referenced-by-count":2,"title":["Epidemiological anomaly detection in Philippine public health surveillance data through Newcomb-Benford analysis"],"prefix":"10.1093","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2230-8984","authenticated-orcid":false,"given":"Samuel John E","family":"Parre\u00f1o","sequence":"first","affiliation":[{"name":"Mathematics Division , , Digos City 8002 , Philippines"},{"name":"University of Mindanao Digos College , , Digos City 8002 , Philippines"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2024,5,1]]},"reference":[{"key":"2024082908131426100_ref1","doi-asserted-by":"crossref","first-page":"57","DOI":"10.1146\/annurev-publhealth-031816-044348","article-title":"Public health surveillance systems: recent advances in their use and evaluation","volume":"38","author":"Groseclose","year":"2017","journal-title":"Annu Rev Public Health"},{"issue":"2","key":"2024082908131426100_ref2","article-title":"The Philippines health system review","volume":"8","author":"Dayrit","year":"2018","journal-title":"Health Syst Transit"},{"issue":"3","key":"2024082908131426100_ref3","first-page":"e23039\u2013e23039","article-title":"Assessing the quality of dengue data in the Philippines using Newcomb-Benford law.
