关于带状疱疹
什么是带状疱疹？
带状疱疹是水痘病毒的重新激活，水痘病毒在初次感染后仍潜伏在体内。首次接触水痘-带状疱疹病毒 (VZV) 表现为水痘，病毒再次激活表现为带状疱疹。带状疱疹通常会影响神经根，如果它涉及面部或前额，可能会非常疼痛和毁容。
带状疱疹是如何传播的？
由于免疫系统低下、压力、疾病、潜在癌症或免疫妥协（在移植患者、化疗患者、HIV 感染、使用类固醇或生物制剂的患者中），带状疱疹可能会重新激活。在老年人中，愈合过程会延长，并且通常与带状疱疹后神经痛的并发症有关，这是一种持续数周和数月的“神经痛”形式。
我为什么要接种带状疱疹疫苗？
带状疱疹疫苗接种适用于：
成人≥50岁
≥18岁的免疫力低下者
准备化疗或免疫抑制治疗/移植的患者
以前接受过 Zostavax 的人
Points to Note:
Laboratory diagnostic tests are not perfect and are not 100% accurate
- We do not have a test for every disease or virus but most of those pathogens that are of public health importance or have long term implications on your health can be tested
- No one single test can be used with absolute certainty to diagnose a disease. Often, we depend on a combination of tests to make a diagnosis
- Sometimes, we have to resort to trial treatment or empiric treatment if investigative tests are inconclusive. If the patient makes a therapeutic response and feels better, we have achieved our goal
- In PUO, we are looking for treatable causes and to rule out sinister causes eg. malignancies so that we do not miss opportunities for early treatment or intervention
