A county-level analysis of association between social vulnerability and COVID-19 cases in Khuzestan Province, Iran

Investigating the impacts of socio-economic vulnerability indicators on COVID-19: A case study of Yazd, Iran

Socio-economic vulnerability plays a major role in affected countries by disasters and emergencies. This study aims to identify the most effective socio-economic vulnerability indicators on COVID-19 cases and severity in the Yazd city. This study was conducted in 2022. Regarding purpose of study, different methods were applied during this research. They were including reviewing scientific research, expert panel sessions, weighting the socio-economic vulnerability indicators by Analytic Hierarchy Process (AHP) and examining the spatially relationships between vulnerability indicators and COVID-19. Excel and GIS software were applied for data analysis using local correlation coefficient. AHP analysis showed that employment, population density, buildings quality and distance from hospitals were obtained the most weight in the related indicators of socio-economic vulnerability. GIS mapping overlying showed that four socio-economic vulnerability sub indicators including percentage of immigrants, age, population density and distance from health centers had spatially relationships with COVID-19 cases and severity. Western, northern and some central regions of Yazd were identified as the COVID-19 hot spots. Local officials and health authorities should pay immediate attention to the most influential socio-econimic vulnerability indicators that are dominant in the Yazd city. They incorporate measures to the regions identified as hot spots because people who located in these areas are more vulnerable to COVID-19 and the other future natual or man-made disasters.

Main social vulnerability indicators in the COVID-19 pandemic in Iran

Background

Social factors play the main role in the vulnerability of exposed countries to disasters. The COVID-19 pandemic as a disaster is not an exception to this fact. This study aimed to determine the main social vulnerability indicators in the COVID-19 pandemic in Iran.

Methods

This study was conducted during the period of 2021-2022 in three phases, including a systematic review, a virtual panel expert, and the Analytical Hierarchy Process. First, the draft of social vulnerability indicators in COVID-19 was extracted through a systematic review. Then, the extracted indicators were finalized and prioritized by the expert panel and the AHP, respectively.

Results

Initially, the literature review found five domains and 38 indicators of social vulnerability in COVID-19. The outcome of the expert panel increased the related domains to six but decreased the indicators to 31. The three prioritized social vulnerability indicators that were determined by the AHP were population density, accessibility to healthcare facilities, and relevant services and vulnerable groups.

Conclusion

Measuring social vulnerability with the identified indicators is valuable for addressing high COVID-19 incidence among socially vulnerable hotspot areas. Regarding the result of this study, further research should be conducted to validate the identified indicators.
