Insights

Travel-associated infectious diseases (TAIDs) like dengue and malaria saw increased incidence in US children

Area of Science:

  • Pediatric infectious diseases
  • Public health surveillance
  • Epidemiology

Background:

  • The Pediatric Health Information System (PHIS) database contains valuable admission, diagnostic, and treatment data from children's hospitals.
  • This data offers a potential resource for monitoring travel-associated infectious diseases (TAIDs).

Purpose of the Study:

  • To assess the utility of the PHIS database for TAID surveillance among children in the U.S.
  • To calculate incidence rates of dengue, malaria, and typhoid fever from 1999 to 2012.
  • To examine trends in TAID incidence in relation to the 2007-2009 economic recession.

Main Methods:

  • Utilized PHIS data from 16 children's hospitals across the U.S. (1999-2012).
  • Calculated cumulative incidence rates for dengue, malaria, and typhoid fever using discharge codes.
  • Analyzed pooled TAID incidence and compared rates before, during, and after the economic recession.

Main Results:

  • Significant increases in the incidence of dengue and pooled TAIDs (dengue, malaria, typhoid fever) were observed.
  • Rates of malaria and typhoid fever showed an upward trend.
  • Admissions for dengue and pooled TAIDs significantly increased among children's hospitals.

Conclusions:

  • The PHIS database serves as a valuable tool for TAID surveillance in pediatric populations within the U.S.
  • Findings highlight the growing burden of TAIDs among children admitted to U.S. children's hospitals.

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Investigation of Disease Outbreaks01:23

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...

Infectious Diseases and Their Occurrence01:28

Infectious Diseases and Their Occurrence

Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable...
