Cervical intraepithelial neoplasia (CIN) is a premalignant lesion that may exist at any one of three stages: CIN1, CIN2, or CIN3. If left untreated, CIN2 or CIN3 (collectively referred to as CIN2+) can progress to cervical cancer. Instead of screening and diagnosis by the standard sequence of cytolo...gy, colposcopy, biopsy, and histological confirmation of CIN, an alternative method is to use a ‘screen-and-treat’ approach in which the treatment decision is based on a screening test and treatment is provided soon or, ideally, immediately after a positive screening test. This guideline provides recommendations for strategies for a screen-and-treat programme

To guide One Health capacity building efforts in the Republic of Guinea in the wake of the 2014–2016 Ebola virus disease (EVD) outbreak, we sought to identify and assess the existing systems and structures for zoonotic disease detection and control. We partnered with the government ministries resp...onsible for human, animal, and environmental health to identify a list of zoonotic diseases – rabies, anthrax, brucellosis, viral hemorrhagic fevers, trypanosomiasis and highly pathogenic avian influenza – as the country's top priorities. We used each priority disease as a case study to identify existing processes for prevention, surveillance, diagnosis, laboratory confirmation, reporting and response across the three ministries. Results were used to produce disease-specific systems “maps” emphasizing linkages across the systems, as well as opportunities for improvement. We identified brucellosis as a particularly neglected condition. Past efforts to build avian influenza capabilities, which had degraded substantially in less than a decade, highlighted the challenge of sustainability. We observed a keen interest across sectors to reinvigorate national rabies control, and given the regional and global support for One Health approaches to rabies elimination, rabies could serve as an ideal disease to test incipient One Health coordination mechanisms and procedures. Overall, we identified five major categories of gaps and challenges: (1) Coordination; (2) Training; (3) Infrastructure; (4) Public Awareness; and (5) Research. We developed and prioritized recommendations to address the gaps, estimated the level of resource investment needed, and estimated a timeline for implementation. These prioritized recommendations can be used by the Government of Guinea to plan strategically for future One Health efforts, ideally under the auspices of the national One Health Platform. This work demonstrates an effective methodology for mapping systems and structures for zoonotic diseases, and the benefit of conducting a baseline review of systemic capabilities prior to embarking on capacity building efforts.

Esta quarta edição do manual se baseia no esquema de avaliação de risco apresentado na terceira edição. Uma avaliação completa, baseada em evidências e transparente dos riscos permite que as medidas de segurança sejam equilibradas com o risco real de trabalhar com agentes biológicos, caso... a caso. Isso permitirá que os países implementem políticas e práticas de biossegurança e biosseguridade laboratoriais economicamente viáveis e sustentáveis que sejam relevantes para suas circunstâncias e prioridades individuais.A necessidade de atualizar as diretrizes de biossegurança de laboratórios internacionais faz parte de uma iniciativa mais ampla para globalizar a biossegurança e enfatizar os princípios e as abordagens que são acessíveis a países que tenham ampla gama de recursos financeiros, técnicos e regulatórios. A OMS revisou o Regulamento Sanitário Internacional em 2005 “para ajudar a comunidade internacional a prevenir e a responder aos riscos agudos de saúde pública que tenham o potencial de cruzar fronteiras e ameaçar pessoas em todo o mundo”. Esses regulamentos exigem que todos os 196 estados-membros da OMS estejam bem preparados para surtos em potencial e novas doenças; isso inclui o diagnóstico precoce e a confirmação laboratorial para facilitar a prevenção e o controle de infecções.

following laboratory confirmation of a patient from a village in Madudu sub-county, Mubende district, central
Uganda.
Therefore the MEDBOX Team cre...ated this issue brief to give a quick overview of the most important documents and training material.

Buruli ulcer is caused by infection with Mycobacterium ulcerans. The disease is reported in more than 33 countries worldwide, but only about half of these countries regularly report data to WHO; most cases are reported from subregions of West and Central Africa. The mode of transmission is not known....
About half of those affected are children aged under 15 years; there is no gender difference. Diagnosis is based mainly on clinical and epidemiological characteristics. Of the four methods used for laboratory confirmation (microscopy, polymerase chain reaction (PCR), histopathology and culture), PCR is the most rapid and widely used. Other rapid methods for detection of mycolactone in lesions from suspected cases, such as fluorescent thin-layer chromatography, are under evaluation in four countries in Africa.
Research to develop point-of-care tests is in progress. Treatment of Buruli ulcer comprises 8 weeks of combined antibiotics (rifampicin and clarithromycin). Complementary therapies such as wound care, skin graft and prevention of disability are needed in some cases to ensure full recovery.
The target set by the World Health Organization (WHO) for control of Buruli ulcer is for countries to achieve a rate of case confirmation by PCR of at least 70%. All endemic countries have at least one PCR facility to support confirmation of cases. However, most countries in the WHO African Region have not been able to reach the target, and the rate of case confirmation has been declining

L’ulcère de Buruli, une infection causée par Mycobacterium ulcerans, touche plus de 33 pays dans le monde, mais un peu moins de la moitié seulement de ces pays communiquent régulièrement des données sur la maladie à l’OMS. La plupart des cas notifiés se trouvent dans les sous-régions d...Afrique occi-
dentale et centrale. Le mode de transmission de l’ulcère de Buruli n’est pas connu. Environ la moitié des personnes touchées sont des enfants de moins de 15 ans et les deux sexes sont concernés à parts égales.
Le diagnostic repose principalement sur l’observation des caractéristiques cliniques et épidémiologiques.
Parmi les quatre méthodes de confirmation utilisées (examen microscopique, amplification en chaîne par polymérase (PCR), histopathologie et mise en culture), la PCR est la plus rapide et la plus courament employée. D’autres méthodes rapides, comme l’utilisation de la chromatographie sur couche mince par fluorescence pour détecter la mycolactone dans les lésions des cas suspects d’ulcère de Buruli, sont actuellement à l’étude dans quatre pays d’Afrique. Des travaux de recherche sont en cours pour mettre au
point des tests utilisables sur le lieu des soins. Le traitement de l’ulcère de Buruli consiste à administrer une association d’antibiotiques (rifampicine et clarithromycine) pendant 8 semaines. Des traitements complémentaires, comme le soin des plaies, les greffes cutanées et la prévention des incapacités, sont nécessaires dans certains cas pour parvenir à une guérison complète.
La cible fixée par l’Organisation mondiale de la Santé (OMS) exigée des pays pour assurer la lutte contre l’ulcère de Buruli est la confirmation d’au moins 70 % des cas par PCR pour chaque pays. Tous les pays d’endémie disposent d’au moins un établissement doté des moyens nécessaires pour effectuer les tests de PCR pour la confirmation des cas. Cependant, la plupart des pays de la Région africaine n’ont pas réussi à atteindre la cible fixée. Un déclin du taux de confirmation a même été observé.

Four (04) new EVD alerts were reported from Rubkona, Nimule, and juba during week 45 (ending 13 November 2022) but only one sample was collected for laboratory confirmation which tested negative. The other three were discarded as they did not meet EVD case definition.
Chagas disease (CD) is caused by Trypanosoma cruzi. When acquired, the
disease develops in stages. For diagnosis, laboratory confirmation is required, and an extensive assessment of the patient’s health should be performed. Treatment consists of the administration of trypanocidal drugs, which may... cause severe adverse effects. The objective of our systematic review was to analyze data contained in the CD published case reports to understand the challenges that patients and clinicians face worldwide.
