    Abstract Objectives: Recent outbreaks of the mpox (monkeypox) virus have been detected in dense sexual networks of gay and bisexual men who have sex with men (GBMSM). The objective of this study is to describe and compare the epidemiological and behavioural characteristics, as well as the sexual networks, of GBMSM diagnosed with mild mpox in Spain.
    Methods: A prospective case-control study was conducted in Spain from July 2022 to February 2023. The study targeted a key population of GBMSM aged 18 years or older. Study participants were categorised into cases, those who were diagnosed with mpox virus infection; and controls, those who were not diagnosed. We examined and compared the sexual network characteristics of the two groups-mpox-positive (mpox-P) and mpox-negative (mpox-N) egos-using χ
    Results: Among the 105 participants, 35 (33.3%) were mpox-P. Compared with mpox-N, mpox-P respondents more frequently reported syphilis (mpox-P: 31.4%; mpox-N: 12.9%) and HIV (mpox-P: 45.7%; mpox-N: 18.6%), and mpox-P individuals to have had at least one sexual contact with a confirmed mpox case (mpox-P: 62.5%; mpox-N: 8.3%). In the egocentric network analysis, mpox-P respondents had a higher prevalence of group sex with alters (mpox-P: 18.5%; mpox-N: 8.9%) and one-time sexual partners (mpox-P: 46.1%; mpox-N: 31.7%). Multivariable logistic regressions showed that reporting stranger/client ties (adjusted OR (aOR)=10.3, 95% CI 1.39 to 76.6) with alters, being vaccinated for mpox (aOR=0.07, 95% CI 0.02 to 0.24) and tie strength heterogeneity (aOR=0.01, 95% CI 0.00 to 0.42) were associated with mpox infection.
    Conclusions: Our findings highlight the role of demographic, epidemiological and sexual network characteristics in the transmission of mpox virus during the outbreak in Spain. These findings have important implications for future prevention efforts.

    Abstract We evaluated the accuracy of patient-collected skin lesions, oropharyngeal, and rectal swabs among 50 individuals enrolled in a study of mpox viral dynamics. We found that the performance of self-collected samples was similar to that of physician-collected samples, suggesting that self-sampling is a reliable strategy for diagnosing mpox.

    Abstract Background: Monkeypox DNA has been detected in skin lesions, saliva, oropharynx, urine, semen, and stool of patients infected during the 2022 clade IIb outbreak; however, the viral dynamics within these compartments remain unknown. We aimed to characterise the viral load kinetics over time in various parts of the body.
    Methods: This was an observational, prospective, multicentre study of outpatients diagnosed with monkeypox in two hospitals and two sexual health clinics in Spain between June 28, 2022, and Sept 22, 2022. Men and women aged over 18 years were eligible if they reported having symptom onset within the previous 10 days of presentation, and were ineligible if disease was severe enough to be admitted to hospital. Samples were collected from five body locations (skin lesions, oropharynx, rectum, semen or vagina, and a dried blood spot) at six time points up to 57 days after the screening visit. Samples were analysed by quantitative PCR and a subset by cell culture. The primary endpoint was time from symptom onset to viral DNA clearance.
    Findings: Overall, 1663 samples were collected from 77 study participants. 75 (97%) participants were men, the median age was 35·0 years (IQR 29·0-46·0), and 39 (51%) participants were living with HIV. The median time from symptom onset to viral clearance was 25 days (95% CI 23-28) in the skin lesions, 16 days (13-19) in the oropharynx, 16 days (13-23) in the rectum, 13 days in semen (9-18), and 1 day in blood (0-5). The time from symptom onset to viral clearance for 90% of cases was 41 days (95% CI 34-47) in skin lesions and 39 days (27-56) in semen. The median viral load in skin lesions was 7·3 log
    Interpretation: In immunocompetent patients with mild monkeypox disease, PCR data alone would suggest a contact isolation period of 3 to 6 weeks but, based on detection of replication-competent virus, this time could be reduced. Based on findings from this cohort of patients, semen testing and prolonged use of condoms after recovery from monkeypox might not be necessary.
