Post-COVID Multisystem Inflammatory Syndrome in the Deployed Environment

Area of Science:

• Infectious Diseases
• Immunology
• Critical Care Medicine

Background:

• Multisystem inflammatory syndrome in children (MIS-C) following SARS-CoV-2 infection is well-documented.
• Multisystem inflammatory syndrome in adults (MIS-A) is a recognized, albeit rare, post-infectious complication of COVID-19.
• Limited reports exist on MIS-A, particularly in deployed military personnel.

Purpose of the Study:

• To report a rare case of multisystem inflammatory syndrome in adults (MIS-A).
• To describe the clinical presentation and rapid progression of MIS-A in a deployed soldier.
• To emphasize the potential severity of MIS-A even after a seemingly benign SARS-CoV-2 infection.

Main Methods:

• Case report detailing a deployed soldier's clinical course.
• Review of initial SARS-CoV-2 infection and subsequent development of MIS-A symptoms.
• Documentation of the rapid progression to a life-threatening condition.

Main Results:

• The patient presented with a benign initial SARS-CoV-2 infection.
• Rapid development of severe, life-threatening multisystem inflammatory syndrome in adults (MIS-A).
• The case occurred in a deployed military setting.

Conclusions:

• Multisystem inflammatory syndrome in adults (MIS-A) can occur following SARS-CoV-2 infection.
• MIS-A may present with rapid deterioration and life-threatening complications.
• Awareness of MIS-A is crucial, especially in diverse clinical settings like military deployments.
