Associations between Minority Health Social Vulnerability Index Scores, Rurality, and Histoplasmosis Incidence, 8 US
Emerging Infectious Diseases
|September 25, 2024
Summary
Histoplasmosis infection rates are higher in rural areas and counties with poor healthcare access, as indicated by the Minority Health Social Vulnerability Index (MH SVI). Addressing these disparities requires increased awareness, better diagnostics, and improved rural health services.
Area of Science:
- Public Health
- Infectious Diseases
- Social Epidemiology
Background:
- Histoplasmosis is an infectious disease caused by the fungus Histoplasma.
- Social determinants of health (SDOH) significantly impact health outcomes.
- Understanding SDOH associated with histoplasmosis is crucial for targeted interventions.
Purpose of the Study:
- To investigate the relationship between histoplasmosis incidence and SDOH.
- To analyze the impact of race/ethnicity, socioeconomic status, and rurality on histoplasmosis.
- To identify specific SDOH contributing to histoplasmosis disparities.
Main Methods:
- Analysis of county-level histoplasmosis incidence data from 8 US states.
- Utilized the Minority Health Social Vulnerability Index (MH SVI) to measure SDOH.
- Employed generalized linear mixed hurdle models for statistical analysis.
Main Results:
- Higher histoplasmosis incidence observed in counties with limited healthcare infrastructure and access (MH SVI).
- Increased incidence correlated with greater rurality.
- Other SDOH showed non-significant or inconsistent associations with histoplasmosis.
Conclusions:
- Limited healthcare access and rurality are key factors associated with histoplasmosis incidence.
- Targeted interventions focusing on rural health services and diagnostics are needed.
- Addressing SDOH can help reduce histoplasmosis-related health disparities.

01:26Factors Affecting the Risk of Infection
14.7K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

731
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.

740
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
