Is there a Relationship between Income and Infectious Disease: Evidence from Cameron County

Abstract

The environments in which people are born, live, learn, work, play, worship, and age affect a wide range of health, functioning, and quality-of-life outcomes and risks. Research on poverty indicates that lower income is linked to poorer health. The lower an individual's income, the higher is his or her likelihood of disease and premature death. Furthermore, some research indicates that a higher risk of contracting an infectious disease may exist for those living in poverty. This study explored the potential existence of a relationship between income and Zika virus. Through analysis using 3.4.0 Version of the R Statistical Package, the median disposable income of the household was found to be significant in predicting the Zika virus counts. Specifically, the study looked at the relationship between household income and the risk of contagion in Cameron County, the southernmost county in Texas, which has been named as BZika cautionaryb y the Centers for Disease Control. Our analysis shows the existence of such a relationship, specifically that an increase in median disposable annual income per household in Cameron County of $100 per month was associated with a 15.6% decrease in the expected rate of occurrence of Zika Virus.

Business Cycle and Public Health: The Moderating Role of Health Education and Digital Economy

“…The increased income will promote the public's well-being and further promote their health, as it greatly empowers an individual's ability to afford healthcare. Some research has indicated that a higher risk of contracting an infectious disease may exist for those living in poverty ( 63 , 64 ). Through the advanced development of ICTs, the capacity to improve health system efficiencies will be greatly increased and medical errors will be significantly reduced.…”

Mapping the Urban and Rural Planning Response Paths to the Pandemics of Infectious Diseases

“…Thereby, the improvement of income reducs the occurrence and spread of infectious diseases. There is a negative correlation between income levels and the incidence and prevalence of infectious diseases (Scarbrough and Holt et al, 2019). For example, conditions such as income levels in cities are generally better than those in rural areas, which makes urban prevention and control capability is higher than in rural areas(UNDP and TheChinaInstituteforReformandDevelopment, 2008; Alirol and Getaz et al, 2011).…”
