Abstract: Based on data from three imported mpox cases in South Korea, the overall attack rate was determined to be 1%, while a secondary attack rate of 14% was estimated in the high-exposure group.

“…In the Republic of Korea, a total of 4 cases of mpox were reported in 2022; the first three cases were epidemiologically linked to foreign outbreaks, while the fourth case resulted from a needlestick injury to a physician. 2 3 4 5 6 7 MPXV isolated from the first case in 2022 was classified into Clade IIb, lineage B.1.1. 8 In April 2023, the first local case without foreign travel history was reported, and subsequent local mpox cases were identified, reaching a peak of 16 new cases per week by late April 2023.…”

We aimed to characterize the genomes of monkeypox virus isolates from the Far East, providing insights into viral transmission and evolution. Genomic analysis was conducted on 8 isolates obtained from patients with monkeypox virus disease in the Republic of Korea between May 2022 and early 2023. These isolates were classified into Clade IIb. Distinct lineages, including B.1.1, A.2.1, and B.1.3, were observed in 2022 and 2023 isolates, with only the B.1.3 lineage detected in six isolates of 2023. These genetic features were specific to Far East isolates (the Republic of Korea, Japan, and Taiwan), distinguishing them from the diverse lineages found in the Americas, Europe, Africa, and Oceania. In early 2023, the prevalence of the B.1.3 lineage of monkeypox virus identified in six patients with no overseas travel history is considered as an indicator of the potential initiation of local transmission in the Republic of Korea.

Rationale for Review Travel-related skin problems are a common reason for healthcare consultations. We present a clinical approach to diagnosing skin diseases in travellers, emphasizing clinical examination and epidemiological clues such as travel history, incubation time and at-risk behaviors. Key Findings Skin problems or manifestations of systemic infections are the third most common health issue encountered by travellers, though their causes and frequency may vary based on the season and destination. The four most frequent skin conditions affecting travellers include arthropod bites, sunburns, hookworm-related cutaneous larva migrans, and bacterial skin and soft tissue infections. Dengue fever is the leading cause of febrile exanthema in travellers returning from Asia, Latin America, and the Caribbean, while hookworm-related cutaneous larva migrans is the most common cause of creeping dermatitis. Notable travel-related infections associated with pruritus include cercarial dermatitis, scabies, creeping dermatitis, and urticaria. Acute schistosomiasis is the most common parasitic cause of acute urticaria in travellers. African tick-bite fever is the most frequently encountered rickettsiosis, typically presenting with single or multiple eschars. Conclusions Diagnostic approaches emphasize the importance of travel history, at-risk activities during travel, and lesion distribution. At-risk activities include sun exposure, walking barefoot, exposure to sea and fresh water, hiking in forested or jungle areas, exposure frequency to mosquitoes and sandflies, poor hygiene and food intake, drug history, and sexual behaviour. Morphological characteristics (vesicula, bullae, pustule, papule, nodule, plaque, oedema, and ulcer), distinguishing between single and multiple skin lesions, localized or generalized, and whether mucosa, scalp, palmar or plantar surfaces are affected, provide further clinical clues. Systemic signs and symptoms such as fever and pruritus will aid in the differential diagnosis algorithms. With a thorough clinical assessment and knowledge of geographic and exposure-related risk factors, the differential diagnosis of travel-associated skin conditions can be narrowed down allowing for timely clinical management.
