Epidemiology: Chickenpox (Varicella)
As stated by to Centers for Disease Control (CDC) (CDC, 2013); chickenpox is a very contagious disease caused by the varicella-zoster virus (VZV). VZV causes a primary infection that is characterized by a rash with macules, papules, and then vesicles. Other symptoms include fever, lethargy, and pruritus. VZV then remains in the body on the sensory nerve ganglia and can reactivate as at a future time as shingles (Herpes Zoster). Chickenpox is spread through airborne, droplet, and contact with infected fluids. Chickenpox is treated by treating the symptoms, and preventing …show more content…

The lack of a social support networks (families, friends and community) has a direct impact of risk for disease. The environment also impacts the development of the disease. Outbreaks are common in schools, daycares, and communal areas where many children gather.
Nurse’s Role
Nurses have developed the specialty of infection control nursing to combat communicable diseases. Infection control nurses educate staff and clients about communicable infectious organisms, and develop and monitor infectious control practices in healthcare settings. Nurses in acute and ambulatory settings are expected to identify, isolate, and treat persons that have signs and symptoms of an acute infection of chickenpox. Data is used to accurately identify cases, and report finding to the appropriate agencies and departments. Furthermore, nurses provide age appropriate vaccination to prevent chickenpox. According to Smith (2009), Community health nurses interview infected persons to help identify contacts placed at risk by exposure to infected individuals, and perform home visits to monitor persons under treatment and ensure compliance with treatment protocols. Nurses also analyze data collected from community cases to develop interventions appropriate for the sociopolitical environment. Varicella surveillance includes documenting and monitoring the impact of varicella vaccination programs on varicella
