Interim Guidance October 2022. This addendum addresses some of the methodological aspects of VE evaluations that have been learned during the past year, as well as those that have become relevant in the current epidemiological setting of the COVID-19 pandemic. For some of the COVID-19 vaccine method...ology issues there are still insufficient data to make a recommendation, in which case different options for approaching VE evaluations are presented.

Brucellosis is widespread in both humans and livestock in many developing countries. The authors have performed a series of epidemiological studies on brucellosis in agro-pastoral areas in Tanzania since 2015, with the aim of the disease control. Previously, the potential of a community-based brucel...losis control initiative, which mainly consisted of the sale of cattle with experience of abortion and vaccinating calves, was assessed as being effective and acceptable based on a quantitative approach. This study was conducted to investigate the feasibility of community-based brucellosis control program using participatory rural appraisals (PRAs) and key-informant interviews. Four PRAs were performed together with livestock farmers and livestock and medical officers in 2017. In the PRAs, qualitative information related to risky behaviors for human infection, human brucellosis symptoms, willingness to sell cattle with experience of abortion, and willingness to pay for calf vaccination were collected, and a holistic approach for a community-based disease control project was planned. All of the communities were willing to implement disease control measures. To avoid human infection, education, especially for children, was proposed to change risky behaviors. The findings of this study showed that community-based disease control measures are promising.

19 August 2022. A monkeypox case investigation form (CIF) has been designed as a tool for Member States and researchers to conduct in-depth epidemiological investigation of suspected, probable and confirmed cases of monkeypox. This form allows to collect data prospectively or retrospectively for bot...h cases and their contacts. The full form is meant to serve as a tool for in-country use and the data are not required to be reported to WHO.

O Ministério da Saúde (MS), por meio da Coordenação-Geral do Programa Nacional de Imunizações (CGPNI) e da Coordenação-Geral de Informações e Análises Epidemiológicas (CGIAE) da Secretaria de Vigilância em Saúde (SVS) publica o Protocolo de Vigilância do Óbito no Contexto da síndrom...e inflamatória multissistêmica pediátrica (SIM-P) associada à covid-19.
A SIM-P é uma nova apresentação clínica potencialmente grave em crianças e adolescentes associada à infecção pelo vírus SARS-CoV-2, que já foi descrita em diversos países, inclusive no Brasil.
Até a semana epidemiológica 27 de 2021 (SE 27) que vai até 10 de julho de 2021, foram notificados 1.105 casos confirmados de SIM-P no território nacional e registrados 69 óbitos (letalidade de 6,2%).
Os dados registrados no Brasil demonstram uma letalidade maior por SIM-P quando comparados a países desenvolvidos. Neste contexto, o objetivo deste Manual é fornecer às equipes de vigilância epidemiológica munici pais, estaduais e distrital subsídios para implantação da vigilância do óbito relacionado à doença, além de investigar quais fatores estão relacionados ao óbito em decorrência da SIM-P no país.

Recency assays use one or more biomarkers to identify whether HIV infection in a person is recent (usually within a year or less) or longstanding. Recency assays have been used to estimate incidence in representative cross-sectional surveys and in epidemiological studies to better understand the pat...terns and distributions of new and longstanding HIV infections.
This technical guidance outlines best practices regarding the appropriate use of HIV recency assays for surveillance purposes and updates 2011 technical guidance from the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) on the use of HIV recency assays.

The number of people at risk from trachoma, the world’s leading infectious cause of blindness, remained stable in 2020 despite disruptions to community-based interventions caused by COVID-19, the World Health Organization (WHO) reported in its Weekly Epidemiological Record.
Chagas disease caused by Trypanosoma cruzi is a public health issue in Latin America. This highly diverse parasite is divided into at least seven discrete typing units (DTUs) TcI-TcVI and Tcbat. Some DTUs have been associated with geographical distribution in epidemiological scenarios and clinical m...anifestations, but these aspects remain poorly understood. Many studies have focused on studying the parasite and its vectors/hosts, using a wide variety of genetic markers and methods. Here, we performed a systematic review of the literature for the last 20 years to present an update of DTUs distribution in the Americas, collecting ecoepidemiological information. We found that the DTUs are widespread across the continent and that there is a whole gamma of genetic markers used for the identification and genotyping of the parasite. The data obtained in this descriptor could improve the molecular epidemiology studies of Chagas disease in endemic regions.

Chagas is a complex, multidimensional phenomenon in which political, economic, environmental, biomedical, epidemiological, psychological, and sociocultural factors intersect. Nonetheless, the hegemonic conceptualisation has long envisioned Chagas as primarily a biomedical question, while ignoring or... downplaying the other dimensions, and this limited view has reinforced the disease’s long neglect. Integrating the multiple dimensions of the problem into a coherent approach adapted to field realities and needs represents an immense challenge, but the payoff is more effective and sustainable experiences, with higher social awareness, increased case detection and follow-up, improved adherence to care, and integrated participation of various actors from multiple action levels. Information, Education, and Communication (IEC) initiatives have great potential for impact in the implementation of multidimensional programs of prevention and control successfully customised to the diverse and complex contexts where Chagas disease persists.

Onchocerciasis used to be an important public health problem in Africa, with over 37 million people infected and millions suffering from debilitating skin disease, terrible itching, impaired vision and
blindness. But the epidemiological situation has improved dramatically over the last two decades.... Community directed treatment with ivermectin has effectively brought the disease under control in most endemic areas where onchocerciasis is no longer a public health risk.

This project aimed to reduce the risk of vector-borne infection with Chagas disease by
controlling triatomine bugs, the vectors transmitting the parasite of Chagas disease, and
establishing an epidemiological surveillance system with community participation.
The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).
