Microbiological Hazards
Published in Dag K. Brune, Christer Edling, Occupational Hazards in the Health Professions, 2020
Varicella-zoster virus is the etiologic agent of chicken pox and herpes zoster. In chicken pox, the virus is transmitted primarily via airborne spread by small-particle aerosols and by large particles.371 However, spread by person-to-person contact occurs and is probably the main mode of transmission of the virus during zoster.

Varicella (chickenpox) is a highly contagious disease that causes febrile rash illness resulting from primary infection by varicella-zoster virus (VZV).1 Person to person transmission of varicella occurs due to direct contact with persons with either varicella or herpes zoster (shingles) or inhalation of infected respiratory secretions. The incubation period for varicella ranges from 10–21 days. The risk of transmission is highest in pediatric patients, and seronegative adult patients and HCWs are also at high risk for acquisition.2 The first step in the prevention of healthcare-associated transmission of VZV is to minimize the number of susceptible HCWs.3 Many similar outbreaks reported to psychiatric health care facilities had occurred due to bad health behaviors.4 The aim of this work is to describe the investigations and control measures that were implemented to contain an outbreak of varicella-zoster infection in one of the psychiatric hospitals of KSA.

Characterized by fever, malaise and generalized pruritic vesicular rash, varicella (also known as chickenpox) is an acute infectious disease triggered by primary infection of the varicella-zoster virus (VZV) (Breuer and Whitley 2007; Prymula et al. 2014). It is transmitted by aerosolized droplet spread and skin contact and is highly transmissible with an attack rate of up to 90% after close contact of patients (Lee et al. 2004). The incubation period of varicella is about 10–21 days (World Health Organization 2014). As the annual incidence increases these years (from 3.17/100,000 in 2005 to 33.86/100,000 in 2015) (Sui et al. 2019), varicella is still China’s critical public health issue.
