This is combined with case information recorded by local Health Protection Teams in the UKHSA national case management system. The posterior estimate for the mean incubation period of monkeypox from the UK sampling was 7.6 days (95% credible interval 6.5 to 9.9) for the ICC model and 7.8 days (6.6 to 9.2) (fig 2 and table 2) for the ICRTC model.

The estimated serial interval posterior distributions for the mean serial interval from the UK sampling was 8.0 days (95% credible interval 6.5 to 9.9) for the ICC model and 9.5 days (7.4 to 12.3) (fig 3 and table 4) for the ICRTC model. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. The time from exposure to onset of symptoms ranges from five to twenty-one days. Cases had the option of answering On what date did your illness begin?, In the 21 days (3 weeks) before first symptom onset did you have contact with anyone with suspected or confirmed monkeypox infection?, and Date of last contact with case. An exposure date was therefore defined as the last date an individual reported contact with a known case in the 21 days before symptoms manifested, and symptom onset was defined as the date symptoms manifested. The Centers for Disease Control and Prevention (CDC) reports there have been at least 350 identified cases of. Work was undertaken in line with national data regulations. Objective To analyse the transmission dynamics of the monkeypox outbreak in the UK, declared a Public Health Emergency of International Concern in July 2022. Infection time is rarely observed directly, so the generation time is generally approximated using the serial intervalthe time from symptom onset in a primary case (an individual with the index infection) to symptom onset in a secondary case (an individual who becomes infected by the primary case).9 Typical monkeypox symptoms are listed on the National Health Service website and include rash (for example, on the mouth, genitals, anus), high temperature, headache, and muscle aches.10 Serial interval and incubation period estimates are important for informing policy decisions around post-infection quarantine periods and post-contact isolation periods, respectively, as well as for understanding the dynamics of viral transmission, such as potential transmissibility before symptoms manifest.1112 Based on observational studies of monkeypox from the Democratic Republic of the Congo, estimates for the incubation period range from 4-14 days and for the serial interval from 8-11 days.1314 For the Western Africa clade that is currently circulating in the UK,15 early research suggests a mean incubation period of between 6.6 and 10.9 days.16 This estimate is, however, based on limited data and thus far no research pertaining to the serial interval has been released. To obtain data on the incubation period we analysed completed case questionnaires and linked infected individuals to probable exposure dates. Monkeypox is a zoonotic infection, caused by the monkeypox virus, that occurs mostly in West and Central Africa. Data were collected on monkeypox from UKHSA health protection teams, targeted testing of infected individuals (with specimens processed by UKHSA affiliated laboratories and NHS laboratories), and questionnaires (collected by UKHSA health protection teams). Purple arrow indicates number of days between primary onset and secondary exposure. Data are obtained from three types of questionnaires: A questionnaire administered by health practitioners, An anonymous self-completed questionnaire, All questionnaires are optional, and individuals are not required to complete all questions. The median age of confirmed and highly probable cases in the UK was 36 years (interquartile range 30 to 44). Monkeypox - Democratic Republic of the Congo. The European Union has confirmed 118 cases of monkeypox; the United Kingdom has confirmed 90 case; and the U.S. has confirmed 9 cases. For the seven primary cases with available personal identifiable information, four matched and three did not match.

Provenance and peer review: Not commissioned; externally peer reviewed. Negative changes due to updates to location information. The estimated mean serial interval was 8.0 days (95% credible interval 6.5 to 9.8) using the ICC model and 9.5 days (7.4 to 12.3) using the ICRTC model. [13] It may spread from infected animals by handling infected meat or via bites or scratches. [22] The origin of several of the cases of mpox in the United Kingdom is unknown. To fit the model to the data, we used a Markov chain Monte Carlo (MCMC) implemented in Stan through the Cmdstanr package, with full model formula (equation 3, fig 1).
