# Concomitant Cytomegalovirus Viraemia in Multisystem Inflammatory Syndrome in Adults (MIS-A) following COVID-19

## TL;DR

This paper reports a case of an adult with MIS-A and CMV infection following COVID-19.

## Contribution

The novelty lies in documenting concomitant CMV viraemia in an adult MIS-A case.

## Key findings

- An adult patient presented with MIS-A following a COVID-19 infection.
- The patient also had concomitant CMV viraemia.
- This case highlights a potential link between CMV and MIS-A in adults.

## Abstract

Multisystem inflammatory syndrome in adults (MIS-A) is recognised as an infrequent complication of coronavirus disease 2019 (COVID-19). This syndrome occurs following COVID-19 infection in some individuals and is characterised by inflammation of multiple organ systems, such as the heart, liver, bowel, and lymph nodes. Cytomegalovirus (CMV) viraemia is associated primarily with immunosuppression. In COVID-19 patients, it has been reported in severe and critical cases. We present a case of an adult patient diagnosed with MIS-A and concomitant CMV viraemia.
