Background

A number of factors can lead to differences in infectious disease morbidity in children versus adults after a trip abroad.

We aimed to investigate the epidemiological and etiological features of infectious diseases in children after international travel.

Methods: we analyzed the medical records of 2135 patients (416 children) who were hospitalized during the period 2009–2017 after return from international travel.

Results

Hospitalized children were under the age of 1 year in 8.7% of cases, 1–3 years - 39.4%, 4–6 years – 17.3%, 7–11 years – 16.8%, 12–17 years – 17.8%. Children were hospitalized after visiting the following main destinations: Turkey (15%), Egypt (12%), Central Asia microregion [11%] and Thailand (9%). Hospitalizations among children occurred mainly in summer (38.0%; CI 33.3–42.4). In adults there were no significant seasonal differences. Children were more likely to have acute diarrhea (18.3 vs 11.1%), acute respiratory tract infections (51.2 vs 41.2%) and enterovirus infections (8.2 vs 3.1%). Among the non-endemic infections for Russia, 8 children were diagnosed with dengue fever, 1 with typhoid, 1 with malaria, and 1 with wild-poliovirus excretion.

Conclusion

children were mainly hospitalized during summer. Among hospitalized children, almost half was under 3 years old. In children acute respiratory infection and intestinal infections predominated, while in adults, vector-borne diseases were more frequently observed.

住院俄罗斯儿童和成人中与旅行有关的高热病的流行病学和病因学特征：在莫斯科的单中心回顾性分析。

背景

许多因素可能导致出国旅行后儿童与成人的传染病发病率存在差异。

我们旨在调查国际旅行后儿童传染病的流行病学和病因学特征。

方法：我们分析了2009年至2017年国际旅行回国后住院的2135例患者（416名儿童）的病历。

结果

住院儿童的年龄在1岁以下的病例为8.7％，1-3岁-39.4％，4-6岁-17.3％，7-11岁-16.8％，12-17岁-17.8％。在访问以下主要目的地后，儿童已住院：土耳其（15％），埃及（12％），中亚微区[11％]和泰国（9％）。儿童住院主要发生在夏季（38.0％； CI 33.3–42.4）。在成年人中，没有明显的季节性差异。儿童更容易出现急性腹泻（18.3比11.1％），急性呼吸道感染（51.2比41.2％）和肠病毒感染（8.2比3.1％）。在俄罗斯的非地方性感染中，有8名儿童被确诊为登革热，1名伤寒，1名疟疾和1名野生脊髓灰质炎病毒排泄。

结论

儿童主要在夏季住院。在住院儿童中，几乎一半在3岁以下。在儿童中，以急性呼吸道感染和肠道感染为主，而在成年人中，以媒介传播的疾病更为常见。
