Answer

The initial presenting symptoms of VZV infection are low-grade fever, malaise, and a rash that is typically vesicular, starts on the trunk and face, spreads centrifugally to other parts of the body, and usually is in various stages of evolution (from vesicles to crusted scabs) by the time of presentation. VZV pneumonia develops in 1 in 400 cases.

VZV pneumonia starts gradually within 1-6 days after the rash appears and manifests with fever, chest tightness, tachypnea, dyspnea, dry cough, cyanosis, and (in rare cases) pleuritic chest pain and hemoptysis. Physical examination reveals minimal findings, with rare rhonchi or wheezes. New chest symptoms are strongly associated with radiologic findings. VZV pneumonia can develop as a mild disease, or it can be severe and rapidly fatal, especially in immunocompromised individuals.

Some patients may be asymptomatic. One study in military personnel noted that only 25% of those with VZV pneumonitis experienced cough and 10% had tachypnea. [62]
