Named contacts are therefore likely to correspond to genuine transmission events. For confirmed and highly probable cases in the UK, where gender information was available, 3,580 (98.6%) were men and 50 were women. The lead author (TW) affirms that the manuscript is an honest, accurate, and transparent account of the study being reported; that no important aspects of the study have been omitted; and that any discrepancies from the study as planned (and, if relevant, registered) have been explained. If clinical symptoms occurred before patients recognised they had symptoms, however, then the true incubation period could be shorter than the patients recognised incubation period. We refer to this model as the double interval censoring and right truncation corrected model (ICRTC). 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. To obtain the serial interval data we used self-reported symptom onset dates and linked case-contact pairs (linked pairs of primary and secondary cases). The 2022 monkeypox outbreak in the United Kingdom is part of the larger outbreak of human monkeypox caused by the West African clade (type) of the monkeypox virus. 13 September 2022. WHO. Many countries around the world, including the UK, have started using smallpox vaccines to prevent smallpox as the two viruses are similar. For the ICC and ICRTC models, the corresponding estimates ranged from 1.8 days (95% credible interval 1.5 to 1.8) to 1.6 days (1.4 to 1.6) shorter at the 25th centile and 1.6 days (1.5 to 1.7) to 0.8 days (0.3 to 1.2) shorter at the median. This update is currently published on Tuesdays, using data extracted by 9.30am on Mondays. Shaded area denotes span of time series where the serial intervals and incubation period distributions were estimated (6 May to 1 August 2022). Monkeypox contact tracing guidance: classification of contacts and advice for vaccination and follow-up. The 2022 monkeypox outbreak in Taiwan is a part of the larger outbreak of human monkeypox caused by the West African clade of the monkeypox virus.According to the Centers for Disease Control, Taiwan's first monkeypox case was reported on 24 June 2022.. As of 15 February 2023, there have been 5 confirmed cases of monkeypox in Taiwan, all of them having been imported from abroad. Of these, 94 were in Scotland, 34 were in Northern Ireland, 46 were in Wales and 3,480 were in England. WHO. Adjustments for interval censoring, right truncation, and epidemic phase bias are essential for data that are coarsely collected28 and linked to probable, not deterministic, exposure events. We do not capture any email address. [24], A large portion of those infected were believed to have not recently traveled to areas of Africa where monkeypox is normally found, such as Nigeria, the Democratic Republic of the Congo as well as central and western Africa. Analysis of the instantaneous growth rate indicates that as of 9 July the epidemic peaked in the UK. In 2020, less than 10% of the largest global health organizations were head-quartered in the African region, and very few of the global health organizations are led by African nationals . 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. [13] It may spread from infected animals by handling infected meat or via bites or scratches. Often, other methods introduce further assumptions to handle this term, which risk introducing bias. 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. A major outbreak of human monkeypox occurred in Katako-Combe, Zaire in 1996, From February 1996 to February 1997, 89 persons in this outbreak were diagnosed with human monkeypox [19], [26]. If we identified negative serial intervals, we assumed that this record in the dataset had incorrectly identified the direction of transmission in the case-contact pairs, and the order of the primary case and secondary contract were reversed. The global transmission of the monkeypox virus has been on a scale not previously seen outside of Central Africa. UK Health Security Agency. Health - Get latest news on Health. 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). 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 lognormal the model was parameterised in terms of the log mean, 1, and log standard deviation, 2, parameters. Mpox Virus in Human Samples other than Skin Rash Lesions and Implications for Transmission. A week later monkeypox was identified in two more people, with no links to the first patient. A milder West African strain of the virus is driving the. It is believed to be transmitted by close contact with sick people, with extra caution for those individuals with lesions on their skin or genitals, along with their bedding and clothing. Considerations for contact tracing during the monkeypox outbreak in Europe, 2022.

To estimate the exponential growth rate, we need to assume an exponential structure to the data. Design Contact tracing study, linking data on case-contact pairs and on probable exposure dates. 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). NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. All three cases belong to the same family. Proportion of patients who reported being gay, bisexual, and other men who have sex with men (GBMSM) and mean age of each study sample compared with the total set of patients. Incubation periods can vary with severity and personal characteristics of infected individuals,29303132 and serial intervals are highly dependent on viral transmission dynamics. The United Kingdom was the first country, outside of the endemic African areas, to experience an outbreak. The Food and Drug Administration (FDA) is urging that providers be "judicious" in prescribing the We then used the pseudo identifier number to link the identified primary case to the line list to obtain the date of symptom onset. We use some essential cookies to make this website work. 73% of cases reported contact with another human case while 27% had known contact with a wild animal. Negative changes due to updates to location information. To understand the transmission dynamics of the monkeypox outbreak, accurate estimates are needed of the time between subsequent infections (generation time) and time from becoming infected to developing symptoms (incubation period). Infection control precautions for contacts (vaccination, daily monitoring, staying home from work) were implemented. Most confirmed cases with travel history reported travel to countries in Europe and North America, rather than West or Central Africa where the mpox virus is endemic. They discovered that the new cases were limited to small outbreaks which did not spread to the entire population. Main outcome measures The incubation period and serial interval of a monkeypox infection using two bayesian time delay modelsone corrected for interval censoring (ICCinterval censoring corrected) and one corrected for interval censoring, right truncation, and epidemic phase bias (ICRTCinterval censoring right truncation corrected). Dissemination to participants and related patient and public communities: We will disseminate the results to governmental organisations and agencies through official channels and publications. WHO Director-General declares the ongoing monkeypox outbreak a Public Health Emergency of International Concern. Supplementary material B shows the results of the Weibull and lognormal models. technical support for your product directly (links go to external sites): Thank you for your interest in spreading the word about The BMJ. This publication is available at https://www.gov.uk/government/publications/monkeypox-outbreak-epidemiological-overview/monkeypox-outbreak-epidemiological-overview-4-october-2022. On the day of the first reported case of monkeypox in the UK (6 May), we estimated that case numbers were doubling every 9.07 days (95% confidence interval 12.63 to 7.08). This study was conducted for the purpose of informing the outbreak response to the monkeypox pandemic. As the global monkeypox outbreak lingers on, health officials are warning that the virus is mutating at a pace that may soon allow it to become resistant to an antiviral drug used to treat patients at risk of serious illness. Red arrow indicates number of days between primary onset and secondary onset (serial interval). Purple arrow indicates number of days between primary onset and secondary exposure. UK health chiefs are already modelling how outbreak among humans could start. A random effect on the day of week accounts for the average difference in reporting between days. Popularity: 6 Visit reuters.com (Chart represents story popularity over time) Other headlines from reuters.com WHO declares global health emergency over monkeypox . Funding: The authors were employed by the UK Health Security Agency but received no specific funding for this study. Third case of monkeypox reported in the UK, in health care worker . During an ongoing epidemic, time delay distribution observations are either right truncated or right censored. In the analysis, we assume that the direction of transmission is based on the date order of symptom onset, because the direction of transmission cannot be otherwise ascertained. 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. Posteriors are reported for the ICC (interval censoring corrected) model and the ICRTC (interval censoring right truncation corrected) model, fit to data from 79 patients using a gamma distribution, Summary statistics of the serial interval for monkeypox, fit to data from 79 patients using a gamma distribution. 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. [2], Mpox (also known as monkeypox[3]) is an infectious viral disease that can occur in humans and some other animals. An isolation period of 16 to 23 days would be required to detect 95% of people with a potential infection. 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. Another strength was the application of robust methods to estimate distributions, adjusting for the key biases of interval censoring and right truncation that are present in the data. 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. [4] Symptoms include fever, swollen lymph nodes, and a rash that forms blisters and then crusts over. Some monitors saw community transmission taking place in the London area as of mid-May,[23] but it has been suggested that cases were already spreading in Europe in the previous months. Monkeypox is a rare infection most commonly found in west or central Africa. With the emergence of COVID-19 and the recent surge in monkeypox cases, scientists and doctors who specialize in infectious disease are issuing increasingly dire warnings, saying wealthy countries can no longer afford to ignore small outbreaks abroad. 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. In the absence of adjustment for right truncation, longer incubation periods from recent infections will be underrepresented. The CDC has also stated that individuals should avoid contact and consumption of dead animals such as rats, squirrels, monkeys and apes along with wild game or lotions derived from animals in Africa. The shorter median estimate for the serial interval relative to the incubation period suggests that pre-symptomatic transmission might be more substantial than was previously thought, which is further supported by linked patient level data. That makes me mad", "US raises monkeypox alert level but says risk to public remains low", "Monkeypox update: Where the outbreak stands now", "Monkeypox contact tracing extended to Scotland", "Monkeypox cases confirmed in England latest updates", "First case of monkeypox confirmed in Scotland", "Monkeypox spread continues with first case reported in Wales", "GHA confirms first case of monkeypox in Gibraltar", "UK Confirms Local Transmission of Monkeypox", "People coming into contact with monkeypox are now being advised to quarantine for 3 weeks", "Principles for monkeypox control in the UK: 4 nations consensus statement", https://en.wikipedia.org/w/index.php?title=20222023_monkeypox_outbreak_in_the_United_Kingdom&oldid=1142072822, (*) total cases = confirmed and highly probable cases, cases up to and including day d (Monday) are reported and hence ref. The duration of symptoms is typically two to four weeks. To adjust for the right truncation, we fitted a double interval censoring and right truncation corrected parametric delay distribution. The maximum time that transmission was detected before symptoms manifested was nine days. Posteriors are reported for the ICC (interval censoring corrected) model and the ICRTC (interval censoring right truncation corrected) model, fit to data from 54 patients using a Weibull distribution, Summary statistics of the incubation period for monkeypox, fit to data from 54 patients using a Weibull distribution. UK Public Health Agencies. Posterior distributions for mean and standard deviation of the serial interval for monkeypox. Figure 6 shows the instantaneous growth rate of case numbers over time and log scale model fit to case counts. 2022-2023 monkeypox outbreak 39 languages An ongoing outbreak of mpox, a viral disease, was confirmed in May 2022. Between 6 May 2022 and 12 September 2022, 3552 cases of monkeypox have been confirmed in the United Kingdom.7 The international dispersion of the virus has resulted in the largest outbreak of monkeypox reported outside of Africa. Therefore, backward contact tracing strategies should account for a pre-symptomatic infectious period when trying to find the contacts of confirmed cases. We considered three parametric distributions: gamma, Weibull, and lognormal. *Personal identifiable information not available and therefore data considered less reliable. From the MCMC output, we obtained a posterior distribution of parameters, which describes the distribution of parameters considered by the model. [13] Diagnosis can be confirmed by testing a lesion for the virus's DNA. 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. These estimates are specific to the demographic distribution of this outbreak (age and sexual orientation) and severity of this clade. However, this would be computationally expensive. This relies on the assumption that the primary case identified by the secondary contact in the questionnaire is the same primary case identified in case-contact pair. Since 10 June 2022, 299 monkeypox cases (MPX) have been reported from 15 EU/EEA countries: Germany (132), Spain (54), France (34), Portugal (22), Netherlands (20), Italy (19), Denmark (4), Austria (3), Sweden (3), Belgium (2), Romania (2), Finland (1), Greece (1), Iceland (1) and Slovenia (1). 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. When negative incubation periods were identified, we assumed that the patient was not infected by the named contact, as this is not possible. We defined a confirmed case as an individual with a positive polymerase chain reaction (PCR) test result for monkeypox virus, and a highly probable case as an individual with a positive PCR test result for orthopoxvirus. Further details on the epidemiology are available in the monkeypox technical briefing. Dont include personal or financial information like your National Insurance number or credit card details. Our finding does, however, provide evidence that there are patients who showed pre-symptomatic transmission in the monkeypox outbreak data. Using the ICC (interval censoring corrected) model and the ICRTC (interval censoring right truncation corrected) model, fit to data using a gamma distribution for the serial interval and a Weibull distribution for the incubation period, with 95% credible interval. We used a previously described method22 to estimate the growth rate of monkeypox cases since the start of the outbreak in England. On 6 May 2022, monkeypox was detected in England in a patient who had recently travelled to Nigeria. A survey of over 2000 Board seats of global health organizations shows that less than 3% of the seats are held by nationals of low-income countries [ 8 ]. TW, CO, RP, and RC developed the model code and wrote the original manuscript. 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 May 18, 2022 - The CDC says it's concerned about an unusual outbreak of monkeypox in the U.K. In other populations and with different disease severity, the incubation periods are likely to differ.29303132. Monkeypox is a misnomer resulting from the fact that it was first discovered at the Statens Serum Institut in Copenhagen in 1958, when outbreaks of a pox-like disease occurred in monkeys kept. RC worked on data processing. Hardworking individual with firm believe in putting all the effort on work and delivering results diligently. From early May 2022 to September 21, 2022, 61,753 confirmed . See: http://creativecommons.org/licenses/by-nc/4.0/. The right truncation primarily affects recent observations and has less of an influence on older observations. TW is the study guarantor. Able to work productively in a fast-paced and challenging environment. Individuals report other individuals who they have been in contact with or who they think might have infected them, but this does not necessarily mean transmission occurred during that contact. Participants 2746 people with polymerase chain reaction confirmed monkeypox virus in the UK between 6 May and 1 August 2022. You have accepted additional cookies. The 2022 multi-country monkeypox outbreak which is an international public health emergency has raised challenging issues for research. At the 95th centile the posterior estimates were 25.7 days (95% credible interval 20.7 to 33.7) for the ICC model and 30.3 days (23.3 to 41.7) for the ICRTC model. [29][31][32], On 1 June, a case was reported in Gibraltar, a British Overseas Territory. Our likelihood function therefore relies on three functions (equation 2, fig 1). < 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. 2022. The outbreak has mainly been in gay, bisexual, and men who have sex with men without documented history of travel to endemic countries. [9], The disease is caused by the monkeypox virus, a zoonotic virus in the genus Orthopoxvirus. Counts of confirmed cases in Wales, Northern Ireland, and Scotland are submitted to UKHSA by Public Health Wales, Public Health Agency Northern Ireland, and Public Health Scotland respectively. We also use cookies set by other sites to help us deliver content from their services. TW, CO, RP, and RC wrote the manuscript revisions. For the seven primary cases with available personal identifiable information, four matched and three did not match. The identification of pre-symptomatic transmission might be indicative of changes to the primary route of transmission. 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.
