Abstract

Background: Ixodes holocyclus, the predominant tick species on the eastern coast of Australia, is responsible for the increasing incidence of tick anaphylaxis (TA) presentations. While ticks thrive under warm and humid conditions, the influence of environmental conditions on TA incidence remains unclear.

Objective: This study aimed to correlate environmental variables with TA presentations in New South Wales (NSW), Australia, to predict tick seasons and forewarn residents of tick-endemic regions.

Methods: Monthly temperature, rainfall, dewpoint, and fire extent data were collected from open-access government resources for Northern and Southern Coastal NSW, and Greater Sydney regions. These were compared with tick bite locations and dates from 278 TA patients from 2005 to 2022, using Pearson's correlation.

Results: In Greater Sydney, TA cases were weakly correlated with rainfall (r = -0.15), temperature (r = 0.26), and dewpoint (9 am: r = -0.22; 3 pm: r = -0.22), and a strong negative correlation with percentage area burned (r = -0.94). Northern and Southern coastal NSW TA cases exhibited similarly weak correlations with rainfall, temperature, dewpoint, and percentage area burned.

Conclusion: Larger bushfires may reduce TA presentations through tick habitat destruction. However, the role of weather variables remains inconclusive, highlighting the need for further research to better understand tick ecosystems, which may aid public health initiatives for tick awareness.

影响蜱过敏表现的环境变量：一项观察性研究。

背景：全圆伊蚊（Ixodes holocyclus）是澳大利亚东海岸的主要蜱种，是导致蜱过敏反应（TA）发病率上升的原因。虽然蜱在温暖潮湿的条件下茁壮成长，但环境条件对TA发病率的影响尚不清楚。目的：本研究旨在将澳大利亚新南威尔士州（NSW）的环境变量与蜱虫表现相关联，以预测蜱虫季节并预警蜱虫流行地区的居民。方法：从新南威尔士州北部和南部沿海地区以及大悉尼地区的开放获取政府资源中收集月度温度、降雨量、露点和火灾范围数据。这些数据与2005年至2022年278例TA患者的蜱虫叮咬地点和日期进行了比较，使用Pearson相关性。结果：在大悉尼地区，TA病例与降雨量（r = -0.15）、温度（r = 0.26）和露点（上午9点：r = -0.22；下午3点：r = -0.22）呈弱相关，与烧伤面积百分比呈强负相关（r = -0.94）。新南威尔士州北部和南部沿海的TA病例与降雨量、温度、露点和烧伤面积百分比也表现出类似的弱相关性。结论：较大的森林大火可能通过破坏蜱类栖息地来减少TA的出现。然而，天气变量的作用仍然不确定，这突出表明需要进一步研究以更好地了解蜱虫生态系统，这可能有助于提高蜱虫意识的公共卫生举措。

期刊介绍： Asia Pacific Allergy (AP Allergy) is the official journal of the Asia Pacific Association of Allergy, Asthma and Clinical Immunology (APAAACI). Although the primary aim of the journal is to promote communication between Asia Pacific scientists who are interested in allergy, asthma, and clinical immunology including immunodeficiency, the journal is intended to be available worldwide. To enable scientists and clinicians from emerging societies appreciate the scope and intent of the journal, early issues will contain more educational review material. For better communication and understanding, it will include rational concepts related to the diagnosis and management of asthma and other immunological conditions. Over time, the journal will increase the number of original research papers to become the foremost citation journal for allergy and clinical immunology information of the Asia Pacific in the future.
