The COVID-19 pandemic resulted in a sharp decline of post-travel patient encounters at the European sentinel surveillance network (EuroTravNet) of travellers' health. We report on the impact of COVID-19 on travel-related infectious diseases as recorded by EuroTravNet clinics.
Travelers who presented between January 1, 2019 and September 30, 2021 were included. Comparisons were made between the pre-pandemic period (14 months from January 1, 2019 to February 29, 2020); and the pandemic period (19 months from March 1, 2020 to September 30, 2021).
Of the 15,124 visits to the network during the 33-month observation period, 10,941 (72%) were during the pre-pandemic period, and 4183 (28%) during the pandemic period. Average monthly visits declined from 782/month (pre-COVID-19 era) to 220/month (COVID-19 pandemic era). Among non-migrants, the top-10 countries of exposure changed after onset of the COVID-19 pandemic; destinations such as Italy and Austria, where COVID-19 exposure peaked in the first months, replaced typical travel destinations in Asia (Thailand, Indonesia, India). There was a small decline in migrant patients reported, with little change in the top countries of exposure (Bolivia, Mali). The three top diagnoses with the largest overall decreases in relative frequency were acute gastroenteritis (-5.3%), rabies post-exposure prophylaxis (-2.8%), and dengue (-2.6%). Apart from COVID-19 (which rose from 0.1% to 12.7%), the three top diagnoses with the largest overall relative frequency increase were schistosomiasis (+4.9%), strongyloidiasis (+2.7%), and latent tuberculosis (+2.4%).
A marked COVID-19 pandemic-induced decline in global travel activities is reflected in reduced travel-related infectious diseases sentinel surveillance reporting.
COVID-19 大流行导致欧洲旅行者健康监测网络（EuroTravNet）的旅行者就诊量急剧下降。我们报告了 EuroTravNet 诊所记录的 COVID-19 对旅行相关传染病的影响。
纳入 2019 年 1 月 1 日至 2021 年 9 月 30 日期间就诊的旅行者。比较了大流行前时期（2019 年 1 月 1 日至 2 月 29 日的 14 个月）和大流行时期（2020 年 3 月 1 日至 2021 年 9 月 30 日的 19 个月）。
在 33 个月的观察期内，该网络共接待了 15124 名就诊者，其中 72%（10941 人）在大流行前时期，28%（4183 人）在大流行时期。非移民患者的月平均就诊次数从 COVID-19 前的每月 782 次下降到 COVID-19 大流行时期的每月 220 次。在非移民患者中，发病后的前 10 个暴露国家发生了变化；意大利和奥地利等 COVID-19 暴露高峰期的国家取代了亚洲（泰国、印度尼西亚、印度）等典型的旅行目的地。报告的移民患者略有减少，前 10 个暴露国家没有变化（玻利维亚、马里）。相对频率总体下降幅度最大的三个诊断分别为急性胃肠炎（-5.3%）、狂犬病暴露后预防（-2.8%）和登革热（-2.6%）。除 COVID-19（从 0.1%上升到 12.7%）外，相对频率总体增加幅度最大的三个诊断分别为血吸虫病（+4.9%）、旋毛虫病（+2.7%）和潜伏性结核病（+2.4%）。
全球旅行活动因 COVID-19 大流行而明显减少，这反映在旅行相关传染病监测报告的减少。
