关于 霍乱
何谓水痘？
水痘是由水痘带状疱疹病毒感染而引起的疾病，可引起发烧和皮疹发痒。皮疹是水泡状的病变，覆盖全身，但通常多集中于面部，头皮以及躯干部位。大多数但并非所有感染者在皮疹出现的前后会出现发热现象。
水痘可能会引起皮肤细菌感染，脑水肿和肺炎等并发症。青少年和成年人是严重水痘的高发病人群。
水痘如何传播？
水痘通过咳嗽、打喷嚏、直接接触、以及因皮肤病变而产生的病毒气雾现象传播。
我为什么应该接种水痘疫苗？
水痘可以通过接种疫苗加以预防。我们建议任何非免疫人群，尤其是那些水痘并发症高风险人群注射接种疫苗预防水痘。
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
