The Epidemiology of Chickenpox The Epidemiology of Chickenpox Epidemiology can be defined as the study of health patterns and causes within a given population. The nursing field that works with these populations to identify causes and preventative measures is known as public health nursing or community nursing. These nurses seek to identify specific data that help a targeted population deal with the incidence and prevalence of certain conditions (Mauer, Smith, F, 2013). Just like any other disease, chickenpox has its own unique epidemiology, which will be explained in further detail throughout this paper. The epidemiologic triangle is applied to chickenpox as well. With the triad, an agent brings the disease, in this case…show more content…
Immunity is established after having chickenpox, and usually lasts throughout the lifetime (CDC, 2011). While getting chickenpox for a second time is rare, the varicella zoster virus can again become active and when it does it is known as shingles. Therefore, persons who have not yet had chickenpox may acquire the disease from a person who has shingles. Once the blisters have crusted over and dried out, the person is generally considered no longer contagious. Incubation is generally cited as 1 ½ to 3 weeks, with the patient being considered contagious 5 days prior to the signs of rash (CDC, 2011). The mode of transmission for chickenpox is either air transmission or direct contact. For example, if a person recently sneezed and a susceptible person inhaled the virus, they are most likely to acquire chickenpox. A person may also acquire the illness by direct contact with sputum or fluid from the blisters of a patient. Since the patient is contagious prior to obvious symptoms, any recent contact with persons should be taken into account so these patients may take the appropriate precautions. Some illnesses may cause a patient to obtain severe symptoms from having chickenpox. These include cancer patients and AIDS patients and any person who is immune suppressed (MedicineNet, 2013). These complications include infections, pneumonia, encephalitis and sepsis (CDC, 2011). Females who have chickenpox in the third trimester have an higher chance of having a
