Evaluation of a web-based self-reporting method for monitoring international passengers returning from an area of emerging infection.
Infectious diseases now(2020)
Abstract
OBJECTIVES:Emerging infectious diseases are a public health issue of international concern. Identifying methods to limit their expansion is essential. We assessed the feasibility of a screening strategy in which each traveler would actively participate in the screening process after an intercontinental flight by reporting their own health status via a web-based self-administered questionnaire.
PATIENTS AND METHODS:In 2015 and 2017, we invited passengers arriving at or departing from Pointe-à-Pitre international airport to answer an online health questionnaire during the four days following their arrival from or at Paris-Orly international airport. SPIRE 1 was intended for passengers arriving at Pointe-à-Pitre and was conceived as a pilot study. SPIRE 2 was an improved version of SPIRE 1 and consisted in three parts, which permitted to further assess the benefits of pre-flight request and email follow-up. Endpoints were the connection rates and response rates to online health questionnaire.
RESULTS:For SPIRE 1, 4/1038 travelers (0.4%) completed the two steps of the online health questionnaire. In SPIRE 2, response rates ranged from 3/1059 (0.3%) to 19/819 (2.3%). Response rates were significantly better when passengers were approached before their flight.
CONCLUSIONS:The yield of an online health questionnaire was unexpectedly low.
