Herpes simplex transmission to chest and face through autoinoculation in an infant

A 4-month-old female infant presented with a vesicular lesion on her left hand present since 1 day. A few days prior to presentation, she had a similar lesion on the lower lip. Two days after presentation, she returned with new lesions on her thorax and upper eyelid. PCR of the vesicle was positive for herpes simplex virus type 1. The transmission to her chest and face probably resulted from autoinoculation, caused by rubbing of the hand on other parts of the body. Transmission of herpes simplex through skin-to-skin contact is a common route of infection in people engaging in contact sports. Antiviral therapy was started because of the extensiveness and expansion of lesions and risk of developing herpetic keratitis. The patient completely recovered. This case shows that in an otherwise healthy infant, multiple herpetic skin lesions were not due to disseminated infection, but through autoinoculation.
