Severe disseminated primary varicella in a patient on long term inhaled corticosteroids

Disseminated primary varicella infection can carry risks of significant morbidity and mortality particularly in immunocompromised populations. Routine, funded childhood vaccination against varicella has significantly reduced associated hospitalization and deaths, however, uptake and efficacy among adults is unknown. We present a case of disseminated primary varicella infection (including rash, pneumonitis, hepatitis and thrombocytopenia) in an immunocompetent patient on long term inhaled corticosteroids for asthma. This case highlights potential risk factors for severe varicella which require further study in adults and raises the need to discuss vaccination in at risk groups including appropriate counselling in those who may be at higher risk.
