Extraction of Disease Surveillance Using Big Data

This document discusses the extraction of disease surveillance using big data. It explores the research progress, method of investigation, and the use of social media data for disease surveillance. The findings show a strong correlation between the collected data and surveillance data from health organizations. The document also includes regression analysis and its application in predicting disease prevalence. Course code: N/A

Extraction of Disease Surveillance Using Big Data
Research Progress/ Method of Investigation
Big data can be used for analysis for extraction of disease surveillance. Today, many
users of social networking shares their health related statistics on web. Such health related
information can use for extraction of diseases (Thompson et al., 2010). Diseases such as
blood pressure, diabetes are most rampant and costly chronic conditions in the world which
cannot be cured. However accurate and timely surveillance data can control these diseases
(Martin-Sanchez, 2014). The aim of this work is to provide results of the data analysis based
on the surveillance of influenza disease using big data. In this paper, therefore, generalized
method is discussed which will extract the fore-coming strokes of different diseases
depending on data. Here data is collected from social media, internet search. This method was
opted since it is a popular data source for disease surveillance using social media since it can
provide nearly instant access to real-time social opinions.
Results/Findings
The objective was to analyze the data collected from social media and internet sources such
as twitter and Facebook to predict surveillance of influenza disease during the most recent
2016–2019 flu season and to analyze the performance at multiple levels of geographic
granularity, unlike past studies that focused on general or regional surveillance. The analysis
of the data was done using Statistical Packages for Social Sciences (SPSS Version 25.0).
Based on the analysis, the estimates of influenza prevalence were strongly correlated with
surveillance data from the Centres for Disease Control and Anticipation for the Health
ministry (r = 0.83, p < 0.001) as well as investigation data from the Department of Health and
Mental Hygiene of (r = 0.92, p < 0.001). Our system detected the weekly change in direction

(increasing or decreasing) of prevalence of influenza with 95% confidence interval, a nearly
twofold increase over a simpler model, demonstrating the utility of explicitly distinguishing
infection tweets from other chatter. The table 1 below shows the correlation effect between
the variables.

By using over 100,000 messages spanning in 5 weeks, we find that our best model achieves a
correlation of 0.81. With this, the correlation coefficient is thus strong and hence we can
conclude that there exist cases of the influenza disease prevalence within the region.

Finally, the regression analysis model can be applied to predict the number of diseases stroke
visits based on near-real-time environmental and social media data with approximately 80%
precision. This prediction can used to take preventative measures for patients and can be used
for treatment purpose.
