ABSTRACT
Intro: The COVID-19 pandemic highlighted a need for an open-source repository of line-list case data for infectious disease surveillance and research efforts. Global.health was launched in January 2020 as a global resource for public health data research. Here, we describe the data and systems underlying the Global.health datasets and summarize the project's 2.5 years of operations and the curation of the COVID-19 and monkeypox repositories. Method(s): The COVID-19 repository is curated daily through an automated system, verified by a team of researchers. The monkeypox dataset is curated manually by a team of researchers, Monday-Friday. Both repositories include metadata fields on demographics, symptomology, disease confirmation date, and others1,2. Data is de-identified and ingested from trusted sources, such as government public health agencies, trusted media outlets, and established openaccess repositories. Finding(s): The Global.health COVID-19 dataset is the largest repository of publicly available validated line-list data in the world, with over 100 million cases from more than 100 countries, including 60+ fields of metadata, comprising over 1 billion unique data points. The monkeypox dataset has over 35,000 data entries, from 100 different countries. 7,325 users accessed the COVID-19 repository and 3,005 accessed the monkeypox repository. Conclusion(s): The Global.health repositories provide verified, de-identified case data for two global outbreaks and are used by CDC, WHO, and other national public health organizations for surveillance and forecasting efforts. The repositories were utilized to share insights into the COVID-19 pandemic and track the monkeypox outbreak using real-time data3-6. We are collaborating with WHO Hub for Pandemic and Epidemic Intelligence to improve coordination, data schemas, and downstream use of data to inform and evaluate public health policy7. Future work will focus on creating a 'turnkey' data system to be used in future outbreaks for quicker infectious disease surveillance.Copyright © 2023
ABSTRACT
Detailed, accurate data related to a disease outbreak enable informed public health decision making. Given the variety of data types available across different regions, global data curation and standardization efforts are essential to guarantee rapid data integration and dissemination in times of a pandemic.
ABSTRACT
On December 31, 2019, the Chinese government announced an outbreak of a novel coronavirus, recently named COVID-19. During the following weeks the international medical community has witnessed with unprecedented coverage the public health response both domestically by the Chinese government, and on an international scale as cases have spread to dozens of countries. While much regarding the virus and the Chinese public health response is still unknown, national and public health institutions globally are preparing for a pandemic. As cases and spread of the virus grow, emergency and other front-line providers may become more anxious about the possibility of encountering a potential case. This review describes the tenets of a public health response to an infectious outbreak by using recent historical examples and also by characterizing what is known about the ongoing response to the COVID-19 outbreak. The intent of the review is to empower the practitioner to monitor and evaluate the local, national and global public health response to an emerging infectious disease.
