A 52-year-old man had 2 days of cough, dyspnea, and fever. Physical examination showed a rash on the trunk and back with clear vesicles on an erythematous base, imaging showed pulmonary infiltrates, and results of laboratory testing were positive for varicella zoster virus DNA and negative for herpes simplex virus 1 and 2. What is the diagnosis and what would you do next?
Bellmann et al. (Wed,) studied this question.
