Yellow fever is a vaccine‐preventable acute viral disease that can rapidly spread and cause serious public health impact. Delay in seeking health care from health facilities is a potential risk of prolonged disease spread. Therefore, this study assessed the delay in health‐seeking behaviour and implications for yellow fever outcomes in the 2019 outbreak in Nigeria. Furthermore, the study examined the factors associated with delayed yellow fever vaccine uptake. A retrospective study was conducted from January to December 2019 using 137 cases recorded in the WHO database. The data were analysed using descriptive (frequency and percentages) and the Chi‐square test. The results were significant at p < 0.05. Results showed a low uptake of yellow fever vaccine (24.1%) among patients and a median total health‐seeking delay of 7 [IQR 7, 9] days. The delay was more among the older age ≥40 years (12 [IQR 12, 29]), females (8 [IQR 8, 11], and rural inhabitants 7 [IQR7, 9], particularly in Izzi LGA (9 [IQR 9, 16] than the other subgroups. Patients' location or place of residence was significantly associated with the yellow fever vaccine uptake (p < 0.000*), and delay (p = 0.003*). Conclusively, the low vaccine uptake was due to the delay in health‐seeking behaviour. Thus, the healthcare system in Nigeria needs to intensify mass participation in immunisation programmes. Interventions that promote behavioural change towards immunisation are required. Also, health promotion campaigns to educate rural people on desirable health‐seeking behaviour are needed.

延迟求医行为：对 2019 年尼日利亚暴发黄热病结果的影响

黄热病是一种可通过疫苗预防的急性病毒性疾病，可迅速传播并造成严重的公共卫生影响。延迟从医疗机构寻求医疗保健是疾病长期传播的潜在风险。因此，本研究评估了 2019 年尼日利亚疫情中寻求健康行为的延迟以及对黄热病结果的影响。此外，该研究检查了与延迟黄热病疫苗接种相关的因素。2019 年 1 月至 12 月使用世卫组织数据库中记录的 137 例病例进行了一项回顾性研究。使用描述性（频率和百分比）和卡方检验分析数据。结果在p 处显着 < 0.05。结果显示，患者对黄热病疫苗的接种率较低 (24.1%)，总求医延迟中位数为 7 [IQR 7, 9] 天。年龄≥40 岁（12 [IQR 12, 29]）、女性（8 [IQR 8, 11] 和农村居民 7 [IQR7, 9]）的延迟更多，尤其是在 Izzi LGA（9 [IQR 9 , 16] 与其他亚组相比。患者的位置或居住地与黄热病疫苗接种显着相关 ( p  < 0.000*) 和延迟 ( p = 0.003*）。最后，疫苗接种率低是由于寻求健康行为的延迟。因此，尼日利亚的医疗保健系统需要加强大众对免疫计划的参与。需要促进行为改变以实现免疫的干预措施。此外，还需要开展健康促进运动，以教育农村人了解理想的求医行为。
