The primary strength of this analysis is the large sample size, obtained from the UKHSA surveillance and contact tracing data, enabling the distributions to be estimated with reasonably narrow credible intervals. 2. Onset to exposure, serial interval, and incubation period for 13 primary cases with monkeypox who had matching personal identifiable information or were matched but without such information. There has recently been an increase in cases in the UK, but the risk of catching it is low. 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). Other approaches can be applied to handle right truncation bias.21 We opted for our approach because the epidemic phase related terms, P(E=e*), cancel each other out, so we do not need to explicitly describe the phase of the epidemic within the model. To expand the UKs capability to detect monkeypox cases, some NHS laboratories are now testing suspected monkeypox samples with an orthopox polymerase chain reaction (PCR) test (orthopox is the group of viruses which includes monkeypox). However, since serial intervals depend on the incubation period this finding is an approximation of the proportion of infections due to pre-symptomatic transmission. We adapted the method from Ward and Johnsen17 and Vekaria et al.18 The double interval censoring corrects for the coarseness of the data, whereby only the date each event occurs is known rather than the time, which leads to a 24 hour window during which each event could have occurred. However, anyone, regardless of sexual orientation or gender identity, who has been in close, personal contact with someone who has mpox is at risk. [11] Of the two types in humans, cladeII (formerly West African clade)[12] causes a less severe disease than the Central African (Congo basin) type. The maximum time before symptoms that transmission was detected for patients who could be linked through personal identifiable infection was four days. Health - Get latest news on Health. Well send you a link to a feedback form. The endemic regions were identified in Africa's central and western areas. In late May, cases started to be reported in the other constituent countries, with Public Health Scotland reporting its first case on 23 May. On the surface, the monkeypox outbreak in the U.S. doesn't look that bad, especially compared with other countries. The UK Health Security Agency had classified the outbreak as "significant and concerning" but says the risk to people "remains low".. Doubling times of cases declined from 9.07 days (95% confidence interval 12.63 to 7.08) on the 6 May, when the first case of monkeypox was reported in the UK, to a halving time of 29 days (95% confidence interval 38.02 to 23.44) on 1 August. Figure 5 shows the relative times from the symptom onset date in the primary case (primary case onset) to the date of exposure for the secondary contact (secondary contact exposure), serial interval, and the incubation period of the 13 case-contact pairs for whom all events could be linked. Investigation into monkeypox outbreak in England: technical briefing 3. Symptoms include fever, swollen lymph nodes, and a rash that forms blisters and then crusts over. In this method, we assume that the primary event (symptom onset in the primary case for serial interval or exposure date for incubation period) for each individual sits within an interval [e1, e2], where e1 is the reported event date and e2 is the day after. There may be mild symptoms, and it may occur . The current strain of monkeypox in the UK shows 48 single mutations in the genome compared with strain sequencing from 2018.27 The impact of these mutations is difficult to assess currently, although several have been associated with increased virulence and severity. 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. Contributors: TW conceived and led the study. < 2022 U.S. Mpox Outbreak Confirmed Cases Locations with cases Notes: Case data reported since January 1, 2022 are provided for situational awareness and subject to change. The outbreak has mainly been in gay, bisexual, and men who have sex with men without documented history of travel to. Able to work productively in a fast-paced and challenging environment. Monkeypox - Democratic Republic of the Congo. The outbreak could spread beyond U.K. borders, the agency said, particularly because there appears . Data on monkeypox in children and adolescents aged <18 years are limited (1,2). Phiri wa Phiri on 2020-Year in Review: Limping with President Chakwera's Tonse admin on ambitious manifesto, clueless leadership. Mpox (formerly named monkeypox) situation update, as of 14 February 2023 Epidemiological update 15 Feb 2023 Translate this page Since the last update on 31 January 2023, and as of 14 February 2023, 18 mpox cases have been reported from two EU/EEA countries. [15], An ongoing outbreak of mpox was confirmed on 6May2022, beginning with a British resident who, after travelling to Nigeria (where the disease is endemic), presented symptoms consistent with mpox on 29 April 2022. As of 1 August 2022, 650 people had completed questionnaires, 54 of whom had provided information on symptom onset date and had reported the date of last contact with a primary case, forming our incubation period cohort. The story of monkeypox feels to experts frustratingly like a replay of the first months of the COVID-19 pandemic in 2020. . Since then, the incidence of the disease has been sporadic. Monkeypox outbreak delays defence report for Scottish MP's Covid trial Margaret Ferrier's defence asks for further pre-trial hearing as virologist who was preparing report works on recent case. As of Tuesday . We used a previously described method22 to estimate the growth rate of monkeypox cases since the start of the outbreak in England. If a substantial proportion of secondary transmission occurs before symptom onset, the implications will be that many infections cannot be prevented by isolating individuals with symptoms. Analysis of these 13 case-contact pairs showed 10 with pre-symptomatic transmission. **Address not yet confirmed. Participants 2746 people with polymerase chain . Therefore, these distributions might not be the same for outbreaks in other settings. Objective To analyse the transmission dynamics of the monkeypox outbreak in the UK, declared a Public Health Emergency of International Concern in July 2022. 2022. Data requests can be made to the Office for Data Release (https://www.gov.uk/government/publications/accessing-ukhsa-protected-data/accessing-ukhsa-protected-data) and by contacting DataAccess@ukhsa.gov.uk. Here, we conducted a systematic analysis of the recent outbreak of MPXV-2022, including its genomic annotation and molecular evolution. [33], On 30 August 2022, 3413 cumulative cases (3,279 confirmed and 134 highly probable cases) of human monkeypox up to (and including) 29 August were reported for the UK. Mpox (also known as monkeypox) is an infectious viral disease that can occur in humans and some other animals. To estimate this smooth function, we fit a generalised additive model to daily confirmed case counts with a negative binomial error structure and log link. Doubling and halving times and log scale model fit of case numbers of monkeypox by reporting date. We also use cookies set by other sites to help us deliver content from their services. Monkeypox, a zoonotic disease, was identified in 1958 in monkeys showing signs of a poxvirus.1 The disease is caused by a virus belonging to the orthopoxvirus genus and was first detected in humans in 1970 in the Democratic Republic of the Congo.2 The disease has since become endemic in that region and spread to other central and west African countries. [13] Diagnosis can be confirmed by testing a lesion for the virus's DNA. This is due to differences in timings of when the data is compiled, and differences in processing of duplicate data (for example, if a person has tested more than once but insufficient information is provided to identify them). Vaccinating less than half of high-risk men may stop monkeypox spread,A modelling study suggests that between 5 and 47 per cent of high-risk men who have sex with men would need to be vaccinated to stop the ongoing monkeypox outbreak When negative incubation periods were identified, we assumed that the patient was not infected by the named contact, as this is not possible. Mpox (previously called monkeypox) is a viral zoonosis, and in humans, it shares several clinical characteristics with smallpox [1,2].Although smallpox has been eradicated worldwide since 1980, mpox is still endemic in parts of Central and Western Africa [3,4,5].However, it should be noted that most of the mpox cases recorded in the 2022 outbreak occurred in Western and European countries . WHO. The mean incubation period and mean serial interval were found to range from 6.6 to 9.2 days and 7.4 to 12.3 days, respectively, when adjusted for right truncation and epidemic phase bias. TW, CO, RP, and RC developed the model code and wrote the original manuscript. Incubation periods can vary with severity and personal characteristics of infected individuals,29303132 and serial intervals are highly dependent on viral transmission dynamics. Blue arrow indicates number of days between secondary exposure and secondary onset (incubation period). Incubation periods and serial intervals are examples of time delay distributions, which describe the distribution of times between two coupled events. 73% of cases reported contact with another human case while 27% had known contact with a wild animal. Supplementary material B shows the results of the Weibull and lognormal models. May 19, 2022. UKHSA health protection teams store data collected during an incident in the HPZone, The line list contains a list of confirmed infected individuals in the UK obtained from test data (compiled and deduplicated) from UKHSA affiliated laboratories, National Health Service trust laboratories, and HPZone data, along with supplementary data from the case questionnaires. Monkeypox contact tracing guidance: classification of contacts and advice for vaccination and follow-up. In other populations and with different disease severity, the incubation periods are likely to differ.29303132. DOI: 10.1001/jamanetworkopen.2022.36993 Corpus ID: 252971060; Using Data From a Short Video Social Media Platform to Identify Emergent Monkeypox Conspiracy Theories @article{Zenone2022UsingDF, title={Using Data From a Short Video Social Media Platform to Identify Emergent Monkeypox Conspiracy Theories}, author={Marco Antonio Zenone and Timothy Caulfield}, journal={JAMA Network Open}, year . Of these, 4 were imported, 2 were cases in household contacts, and one was a case in a health care worker involved in the care of an imported case. Pre-symptomatic transmission may be facilitated by specific types of high intensity interactions (eg, sexual contacts) where lower pre-symptomatic viral loads are infectious. A side effect of this is that, assuming the linked pair are a genuine transmission event, we cannot directly ascertain the direction of transmission. The United Kingdom was the first country, outside of the endemic African areas, to experience an outbreak. Monkeypox virus, a zoonotic orthopox DNA virus related to the virus that causes smallpox, was first described in humans in 1970 in the Democratic Republic of Congo (formerly Zaire). technical support for your product directly (links go to external sites): Thank you for your interest in spreading the word about The BMJ. For example, more than half of respondents to case questionnaires in the UK had a history of a sexually transmitted infection over the past year, and 31% had at least 10 or more sexual partners in the past three months.25 In the UK outbreak, the median age of infected individuals was 37 years,25 in contrast with earlier outbreaks in the Democratic Republic of the Congo where in 2016 the median age was 10 years and by 2020 only 42% of cases were older than 5 years.1426 This is indicative of changes in the primary routes of transmission for the monkeypox virus in the 2022 epidemic. In early August, the Biden administration declared monkeypox a public health emergency with several states such as California and Illinois, and cities like New York and San Francisco following suit. England counts may differ from those published in the Notifications of infectious diseases (NOIDs) causative agents weekly report. Since 25 July 2022, the monkeypox case definition recognises those who are orthopox-positive as highly probable cases, and those who test positive on a monkeypox PCR test as confirmed cases. A Weibull distribution gave the best fit to the data for both models (see supplementary material A for results of the lognormal and gamma models). Where we have identified any third party copyright information you will need to obtain permission from the copyright holders concerned. If an individual was identified as a contact by a case and became a case or was already a case, we recorded these as a case-contact pair. The global transmission of monkeypox from May 2022 in non-endemic countries necessitated further understanding of the transmission dynamics of the virus. However, this would be computationally expensive. TW is the study guarantor. 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). Nigeria has.

The mean incubation period was estimated to be 7.6 days (95% credible interval 6.5 to 9.9) using the ICC model and 7.8 days (6.6 to 9.2) using the ICRTC model. For the more reliable sample where personal identifiable information was available for linkage, this time decreased to four days, with three out of the four more reliable (ie, personal identifiable information available) case-contact pairs showing pre-symptomatic transmission. In particular, symptom onset date is defined as the date patients noticed they had an infection. 2022-2023 monkeypox outbreak 39 languages An ongoing outbreak of mpox, a viral disease, was confirmed in May 2022. Tom Clarke Science and technology editor @aTomClarke Wednesday 1 June 2022 17:12, UK Why you can trust Sky News Self-isolation is not mandatory. Update on Monkeypox in Children, Adolescents, and People Who are Pregnant or Breastfeeding; Melioidosis in the United States: What Clinicians Need to Know Following Newly Discovered Endemicity; Update on 2022 Ebola Outbreak in Uganda; Situational Update for Clinicians about Severe Monkeypox Virus Infections The data were found to be best described by a gamma distribution for both models. This corresponds to the date when the patient recognised that they had symptoms of monkeypox. 2020 Election Business Tech . ECDC. TW and CO developed the methodology. Funding: The authors were employed by the UK Health Security Agency but received no specific funding for this study. Firstly, we linked case-contact pairs to questionnaire records for each secondary contact, which enabled the primary case and the exposure date to be identified for the secondary contact. [5] The initial cluster of cases was found in the United Kingdom, [6] where the first case was detected in London on 6 May 2022 [7] in a patient with a recent travel history from Nigeria (where the disease is endemic ). The identification of pre-symptomatic transmission might be indicative of changes to the primary route of transmission. 2 The ongoing outbreak was first reported from the United Kingdom by the UK Health Security Agency on May 7, 2022. Infection control precautions for contacts (vaccination, daily monitoring, staying home from work) were implemented. Dont worry we wont send you spam or share your email address with anyone. The limit of detection was 15.32 copies/L for F-RPA and 8.53 copies/L for VF-RPA, 3. For confirmed and highly probable cases in the UK, where gender information was available, 3,580 (98.6%) were men and 50 were women. For both distributions, it is assumed that the mean follows a normal distribution prior, with mean 5 and standard deviation 1, and that the shape parameters follow a flat prior. United States now has the world's biggest outbreak of monkeypox: . These estimates are specific to the demographic distribution of this outbreak (age and sexual orientation) and severity of this clade. As of 1 August 2022, 92 records (from 650 questionnaires) showed complete data for exposure date from the questionnaire and the pseudo identifier number needed for linking the datasets. Although the outbreak was large, however, incidence was still low relative to the population size at risk. They discovered that the new cases were limited to small outbreaks which did not spread to the entire population. Therefore, backward contact tracing strategies should account for a pre-symptomatic infectious period when trying to find the contacts of confirmed cases.
