Abstract: 【Abstract】 Objective To investigate clinical features, treatment and prognosis of herpes zoster during pregnancy or the perinatal period. Methods Clinical data were collected from female inpatients with herpes zoster during pregnancy or the perinatal period in the First Affiliated Hospital of Zhengzhou University from January 2011 to December 2020, and clinical characteristics, treatment and prognosis were retrospectively analyzed. Results A total of 25 patients were included in the study, including 22 pregnant patients at 10 - 38 gestational weeks （1 in the first trimester, 13 in the second trimester, and 8 in the third trimester） and 3 patients during the first postpartum week; their age ranged from 22 to 37 years, and the disease course varied from 2 to 9 days. Skin lesions were located on the head and face in 8 cases, on the chest and back in 5, on the waist and abdomen in 7, on the upper limbs in 1, on the lower limbs in 3, as well as on the perineum in 1; 3 patients presented with disseminated herpes zoster. The patients all presented with erythema, papulovesicles and blisters, which were accompanied by bloody bullae in 4 patients, by bullae in 3, as well as by erosions and exudations in 6; 5 patients had fever, 7 had mild pain, 6 had moderate pain, and 11 had severe pain. Sixteen pregnant patients and 3 postpartum patients received antiviral therapy （oral or intravenous infusion of acyclovir, vidarabine monophosphate, foscarnet sodium-sodium chloride injection）, 24 patients were treated with neurotrophic drugs, 1 pregnant patient and 3 postpartum patients received analgesic treatment, and other treatments included anti-infective therapy, wet compress, infrared radiation, etc. Preterm delivery occurred in 1 pregnant patient, other pregnant patients had full-term deliveries, and no abnormalities were observed in neonates.
