![]() ![]() These health care workers should be offered varicella vaccine within 3-5 days after exposure if it is not otherwise contraindicated. Should be furloughed from days 8-21 after exposure or removed from patient care settings during this time.Without any documented varicella vaccine:.Monitor for symptoms of varicella from days 8-21 after exposure. Should receive a second dose of varicella vaccine.With 1 documented dose of varicella vaccine:.Should be monitored daily for symptoms of varicella from days 8-21 after exposure.With adequate evidence of immunity to varicella:.See Ensuring Immunity to Varicella in Health Care Workers for more information. This information should be documented and readily available. To prevent transmission of varicella in health care facilities, all health care workers should have evidence of immunity to varicella. Management of exposed health care workers This differs from the varicella recommendations. It is not indicated for newborn infants whose mother had onset of zoster around delivery to receive VariZIG.Hospitalized preterm infants less than 28 weeks of gestation or birthweight of 1000g or less, regardless of maternal immunity. ![]() Hospitalized preterm infants (28 weeks or more) whose mother lacks evidence of immunity against varicella.The following individuals should receive VariZIG within 10 days of exposure:.Healthy individuals age 12 months and older should be given varicella vaccine (as long as it is not contraindicated) within 5 days of exposure.Health care providers should refer to CDC's Assessing Immunity to Varicella guidance when verifying history of disease in patients.Įxposed individuals without evidence of immunity should be offered post-exposure prophylaxis in the following situations: Health care provider diagnosis of varicella or zoster or verification of history of varicella or zoster disease.For health care workers, pregnant women, and immunocompromised persons, birth before 1980 should not be considered evidence of immunity.Laboratory evidence of immunity or laboratory confirmation of disease.Children age 4 years and older, adolescents, and adults: 2 doses of varicella vaccine.Children age 12 months to 4 years: 1 dose of varicella vaccine.Documentation of age-appropriate varicella vaccination:.For disseminated zoster, exposures include those in the same 2- to 4- person bed room, adjacent beds in a large area, or face-to-face contact.Įvidence of immunity to varicella includes:.For localized zoster, exposures include those with intimate contact (i.e., changing bandages, touching, hugging).Disseminated zoster is likely as infectious as varicella.Įvaluate evidence of immunity to varicella in all individuals exposed to zoster. For disseminated zoster, transmission occurs through airborne and droplet transmission, in addition to contact with fluid in the blisters of the rash.A person is not infectious before the blisters appear or after the rash has crusted over. For localized zoster, transmission occurs through contact with the fluid in the blisters of the rash.However, if someone is not immune to varicella and is exposed to zoster, they may develop varicella disease. Only health care workers with adequate immunity to varicella should care for patients with zoster.Those without immunity to varicella should not enter the room. If this is unavailable, place patients in their own room and keep the door closed. Place patient in negative airflow rooms.If the rash is disseminated (lesions outside the primary or adjacent dermatomes), follow standard precautions plus airborne and contact precaution until the lesions are crusted, regardless of if the patient is immunocompromised or immunocompetent.Only health care workers with adequate evidence of immunity to varicella should care for patients with zoster.Ĭontrol measures for patients with disseminated or generalized rash.If dissemination is ruled out, follow standard precautions and cover all lesions until lesions are crusted. If a patient is immunocompromised and the rash is localized, follow standard precautions plus airborne and contact precautions until disseminated infection is ruled out.If the patient is immunocompetent and the rash is localized, follow standard precautions and cover all lesions until lesions are dry and crusted.Managing Herpes Zoster (Shingles) Exposures in Health Care Settingsĭownload PDF version formatted for print: Managing Herpes Zoster (Shingles) Exposures in Health Care Settings (PDF) Control measures for patients with localized rash ![]()
