Cat scratch disease (CSD) is caused by Bartonella henselae (B. henselae) and presents as lymphadenopathy following close contact with cats. However, in context of the global COVID-19 pandemic, clinical manifestations of CSD may vary, posing new challenges for healthcare professionals. Here we describe a case of a 54-year-old male with painful left upper arm mass, which gradually resolved until he was infected with COVID-19. The mass then rapidly progressed before admission. Meanwhile, pulmonary symptoms including pleural effusion emerged simultaneously. The cause was undetermined with routine blood culture and pathological test until the next generation sequencing (NGS) confirmed the presence of B. henselae. We believe this case is the first to report localized aggravation of CSD after COVID-19 infection and hopefully, offers treatment experience for clinicians worldwide.

**Comment**

On a personal note: both my husband and I required Bartonella treatment for a relapse after COVID.  What the abstract does not mention is if this patient received the mRNA gene therapy shot which would complicate matters even more. Since his presentation was in January of 2023, he very well could have had multiple shots.

While the case report was about a severe Bartonella manifestation, please know Bartonella can present a million different ways.  Please read:  https://madisonarealymesupportgroup.com/2019/04/24/human-bartonellosis-an-underappreciated-public-health-problem/
