What is a common complication associated with varicella?

The complication commonly associated with varicella (chickenpox) is pneumonia. This is particularly significant because varicella can lead to viral pneumonia, especially in adults, immunocompromised individuals, and those with underlying respiratory issues. The risk of pneumonia increases with the severity of the varicella infection, and typical symptoms may include cough, difficulty breathing, and chest pain, which require prompt medical attention.

Pneumonia can occur either as a direct consequence of the viral infection or secondary to a bacterial superinfection following varicella. This complication is particularly noteworthy in clinical settings, as it can lead to severe morbidity and requires appropriate treatment. Early recognition and management of pneumonia in patients with varicella are crucial for improving outcomes.
