[Recurrent herpes infections. Viral isolation and serological study]

Area of Science:

• Virology
• Immunology
• Dermatology

Context:

• Recurrent herpetic infections pose a significant health challenge.
• Understanding viral shedding and serological profiles is crucial for management.
• Herpes simplex virus (HSV) types 1 and 2 are common pathogens.

Purpose:

• To investigate virological and serological aspects of recurrent herpes infections.
• To determine viral shedding rates during symptomatic and asymptomatic periods.
• To analyze HSV typing and its correlation with clinical presentation and patient demographics.

Summary:

• A study followed 17 patients with recurrent herpes (labial, genital, buttocks) over four months.
• Viral isolation was more frequent during active lesions (59%) than asymptomatic periods (6.4%), suggesting underestimation of asymptomatic shedding.
• No significant changes in antibody titers (HAI technique) were observed. Serological typing confirmed 100% of labial herpes as HSV-1, while genital herpes was 40% HSV-1 and 60% HSV-2.
• Genital HSV-1 infections were prevalent in patients under 30, whereas HSV-2 was more common in those over 45.

Impact:

• Findings highlight the importance of frequent sampling for detecting asymptomatic viral shedding.
• The study provides insights into the distinct epidemiological patterns of HSV-1 and HSV-2 in genital herpes based on age.
• Results can inform clinical diagnosis, patient counseling, and targeted prevention strategies for recurrent herpes.
