在热带地区，水痘对成人和儿童都有影响。因此，热带地区的医护人员很容易受到医院获得性水痘感染的影响，他们可能会将感染传播给住院的易感人群。尽管水痘疫苗是安全有效的，但其费用阻碍了其在常规免疫方案中的使用。为了评估为易感的医护人员接种疫苗以防止医院获得性传播是否合理，我们记录了我们医院医护人员中水痘的频率。1993-1997年间，共有96人因水痘入院；工作人员和实习护士占76%。2月至4月为录取高峰期。护生年发病率分别为0.78/百人年和1.54/百人年。虽然该地区每4-5年发生一次水痘社区暴发，但每年都会发生医院水痘暴发。这带来了向住院患者传播的风险，对免疫受损的人会产生严重后果。因此，我们建议对易感的医护人员进行系统的选择性疫苗接种，以打破医院人员每年爆发水痘的循环。(C)2001年医院感染学会。
In tropical regions, chickenpox affects both adults and children. Therefore, healthcare workers in the tropics are vulnerable to hospital-acquired varicella infection and they may transmit infection to susceptible hospitalized individuals. Although the varicella vaccine is safe and effective, its cost is a deterrent to its use in routine immunization programmes. In order to assess whether vaccination of susceptible healthcare workers to prevent hospital-acquired transmission may be justified, we have documented the frequency of varicella among healthcare workers in our hospital. There were 96 admissions for varicella during the 1993-1997 period; staff and student nurses accounted for 76%. The peak season of admission was from February to April. The attack rate in staff and student nurses was 0.78 and 1.54 per 100 person-years, respectively. While community outbreaks of varicella occur in this region once in 4-5 years, hospital outbreaks of varicella occurred every year. This poses the risk of transmission to hospitalized patients, with serious consequences among immunocompromized individuals. Therefore, we recommend systematic selective vaccination of susceptible healthcare workers to break this cycle of annual varicella outbreaks among hospital personnel.
