Diagnosis of varicella with typical clinical course or symptoms is easy. However, early diagnosis of patients with non-typical skin findings and a variety of associated symptoms is more difficult. This paper reports a 4-year-old girl with varicella, which was confirmed by a loop-mediated isothermal amplification (LAMP) assay.
She had a fever, right bulbar conjunctival injection, strawberry tongue, edema of the extremities, pale pink erythema on the trunk and extremities, and two vesicles on her finger and wrist. VZV DNA was detected in vesicle swabs using the LAMP assay, thus providing a definitive diagnosis of varicella. On the other hand, VZV-IgM was negative. The early diagnosis of varicella in terms of infection control is very important, and rapid testing by the LAMP assay using a vesicle swab maybe a useful diagnostic tool.
