黄热病（英语：Yellow Fever, Yellow Jack, Yellow Plague，英语俗称黄杰克、黑呕，有时又称美洲瘟疫）是一种急性病毒病。症状通常包括发烧、冷颤、食欲下降、恶心、肌肉痛（特别是背部）与头痛。症状通常在发病5天内会改善；有些病人会在症状改善1到2天后，发烧再度发生，出现腹痛，肝脏损伤导致黄疸，这类病患并发出血和肾衰竭的风险较高。

黄热病是一种黄病毒科的节肢介体病毒引起的，此病毒是最小的人外核糖核酸病毒之一，主要的传播方式是蚊虫叮咬。黄热病只会感染人类、灵长类、以及数种蚊虫。在都市中，主要的黄热病病媒蚊是埃及斑蚊。患黄热病初期的症状相当不容易与其他疾病分辨，若要确认，通常需要采取血液检体接受聚合酶连锁反应试验。

Yellow fever is an acute viral disease. In most cases, symptoms include fever, chills, loss of appetite, nausea, muscle pains particularly in the back, and headaches. Symptoms typically improve within five days. In some people within a day of improving, the fever comes back, abdominal pain occurs, and liver damage begins causing yellow skin. If this occurs, the risk of bleeding and kidney problems is also increased.
