According to Preetam A. Cholli, MD,<\/b> a medical resident at Vanderbilt University, and colleagues, mpox remains an international public health threat, with WHO declaring public health emergencies in responses to outbreaks in 2022 and 2024. Yet the long-term physical, behavioral and psychosocial aftereffects of the clade II mpox virus, \u201cand specifically clade IIb, have not been well documented,\u201d they wrote.<\/p>\n

The 2022 outbreak, which resulted in over 87,000 cases and 140 deaths in 111 nations \u2014 including the United States \u2014 was declared over in May 2023. Studies on this outbreak \u201ccorrelated abscesses or superinfections during acute mpox with reduced quality of life or sexual performance 4 to 6 months later; scarring after 12 to 15 months; and clinical, virologic and immunologic data up to 24 months after mpox,\u201d the researchers wrote.<\/p>\n
In the current analysis, Cholli and colleagues assessed post-mpox sequelae among adults who attended HIV, HIV pre-exposure prophylaxis or sexually transmitted infection clinics in New York City or Houston and were either diagnosed with mpox from May 2022 to January 2023 (n = 154) or were at risk for, but never diagnosed with, mpox (n = 201).<\/p>\n
All the patients completed psychosocial and behavioral self-assessments, while those diagnosed with mpox were physically examined by a clinician.<\/p>\n
The researchers noted the proportion of patients reporting increased psychobehavioral symptoms was generally similar between the two groups.<\/p>\n
They found that 58% of patients who had experienced mpox had at least one persistent sequela 11 to 18 months after acute illness. They added that 56% had appearance-related sequelae, but most had \u201cfewer than 10 scars or sites of discoloration and two or fewer body sites involved.\u201d<\/p>\n
Cholli and colleagues wrote that having confluent acute mpox lesions sized 2 cm or larger was the only component of the Mpox Severity Scoring System tied to any long-term sequelae in their multivariable analysis.<\/p>\n
Thus, \u201cclinicians should consider more aggressive monitoring and treatment or early dermatology consultation to try to mitigate the possibility of long-term scarring for lesions at or exceeding 2 cm in size,\u201d they wrote.<\/p>\n
The researchers also reported that 13% patients had functional sequelae, among whom 50% had ongoing anorectal disfunction and 35% had ongoing urinary dysfunction. Only 2% reported that their activities of daily living were affected.<\/p>\n
\u201cNotably, a few participants had undergone an interventional procedure to treat mpox sequelae or still required assistive devices, underscoring some patients\u2019 needs for more intensive medical management,\u201d the researchers wrote.<\/p>\n
But they added that almost 90% of participants who had mpox rated their health as good, very good or excellent at the time of the study\u2019s evaluation \u201cand only a few post-mpox participants had ongoing needs requiring use of health services at that time.\u201d<\/p>\n
Cholli and colleagues acknowledged that the study only enrolled participants in two regions of the U.S., meaning the findings may not be generalizable to the country\u2019s entire population.<\/p>\n
Additionally, the analysis \u201cmay have been too small to detect some associations between acute symptoms, persistent sequelae and other outcomes,\u201d they wrote. <\/p>\n
The researchers concluded the data still \u201cprovide informative context for characterizing the types of, and risk for, persistent physical and psychosocial sequelae\u201d that may follow mpox.<\/p>\n
