Effectiveness of screening for Ebola at airports

Travel-related infections in mainland China, 2014–16: an active surveillance study

“…Active surveillance at entry-exit ports can help with timely identification of people with emerging or re-emerging infections to prevent or at least postpone local transmission. 36,37 In addition to entry surveillance, follow-up surveillance-especially contact tracing of highly communicable infections-will be necessary to understand the entire profile of travel-related infections.…”

The dynamics of travel avoidance: The case of Ebola in the U.S.

“…Bogoch et al (2015) estimated that 2-8 travelers with the Ebola virus departed monthly on a commercial flight from Liberia, Sierra Leone, and Guinea. Both entry and exit screenings of passengers coming from Africa into Europe or other Western nations helped to detect at least 50% of infected individuals (Read, Diggle, Chirombo, Solomon, & Baylsis, 2015).…”

Analyzing Variability in Ebola-Related Controls Applied to Returned Travelers in the United States

“…Others have assessed the potential effectiveness of exit screening, entry screening, and movement restrictions in the context of Ebola and other infectious diseases (though no studies have directly assessed the repeated symptom monitoring and tiered controls approach recommended by CDC), [16][17][18][19][20][21][22][23][24][25] and our purpose is not to reassess the overall value of the control measures employed by various jurisdictions. Rather, we seek to characterize and explain variability in approaches taken in order to identify challenges that are likely to recur during future public health emergencies.…”
