Emerging Infectious Diseases
|January 23, 2020
Summary
Hospital patients were surveyed about recent international travel to identify risks of emerging infectious diseases. This analysis focused on Zika virus exposure, demonstrating a method for tracking potential disease importation.
Area of Science:
- Public Health
- Epidemiology
- Infectious Diseases
Background:
- Emerging infectious diseases pose a global health threat.
- International travel facilitates the rapid spread of pathogens.
- Monitoring imported infections is crucial for public health preparedness.
Purpose of the Study:
- To assess the risk of emerging infectious disease importation through international travel.
- To analyze patient data for potential exposure to specific pathogens, such as Zika virus.
Main Methods:
- Retrospective analysis of 12 months of deidentified hospital patient data.
- Inclusion of patient demographics and international travel history (within 30 days).
- Examination of diagnoses related to potential infectious disease exposure, specifically Zika virus.
Main Results:
- Identified patient demographics associated with international travel.
- Documented travel destinations linked to potential infectious disease exposure.
- Quantified cases with diagnoses indicative of Zika virus exposure.
Conclusions:
- The study highlights the utility of querying hospital patients about travel history.
- This approach can effectively identify potential importation of emerging infections.
- The methodology provides a framework for monitoring and managing infectious disease risks.
