The Committee discussed the implications for preparedness for smallpox-like events reflected by the ongoing COVID-19 pandemic. The Committee noted how quickly diagnostics and vaccines could be developed and deployed when resources and political will were abundant. This rapidity was also due to the f...act that the genetic sequence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had been shared worldwide. It was noted that in one country SARS-CoV-2 had been reconstructed in a laboratory from the viral genome sequence before the first case of COVID-19 had been reported, highlighting the benefits of synthetic biology technologies for accelerated development of diagnostics as well as the oft-described potential risks. Lessons learned about clinical care during the COVID-19 pandemic were also discussed.

A varíola dos macacos é uma doença infeciosa emergente causada por um vírus transmitido aos humanos por animais infetados, na sua maioria roedores. Pode ser propagado a outras pessoas, mas a transmissão de pessoa para pessoa, isoladamente, não pode facilmente sustentar um surto. A apresentaç...o clínica é semelhante à observada no passado com a varíola, mas menos grave. A varíola foi erradicada mundialmente em 1980; no entanto, a varíola dos macacos ainda ocorre esporadicamente em partes da África Central e Ocidental, perto das florestas tropicais húmidas. Normalmente, a mortalidade nos surtos da varíola dos macacos tem sido de 1 a 10%, mas com os cuidados adequados, a maioria dos doentes recupera. Este curso fornece uma introdução geral à varíola dos macacos e destina-se aos profissionais de saúde responsáveis pela prevenção e controlo da varíola dos macacos.

La variole du singe est une maladie infectieuse émergente causée par un virus transmis par des animaux infectés, le plus souvent des rongeurs. Elle peut ensuite se propager d’une personne à l’autre, mais la transmission de personne à personne ne peut à elle seule entretenir une éclosion. ...La présentation clinique est semblable à celle observée chez les patients atteints autrefois de la variole, mais moins grave. La variole a été éradiquée dans le monde entier en 1980. Cependant, la variole du singe est encore présente sporadiquement dans des régions d'Afrique centrale et occidentale, près des forêts tropicales humides. De manière générale, le taux de létalité dans les épidémies de variole du singe est de 1 à 10 %, mais avec des soins appropriés, la plupart des patients se rétablissent.

Monkeypox is an emerging viral zoonosis with symptoms similar to those observed in smallpox patients, although less severe. Since the global eradication of smallpox in 1980, monkeypox has emerged as the most important orthopoxvirus in humans. The Advisory Committee on Variola Virus Research (ACVVR) ...which meets annually to oversee smallpox research has highlighted the importance of diagnostics that could distinguish between variola and other strains of orthopoxviruses, including monkeypox virus. The ACVVR encourages the positive effects of current smallpox research on all orthopoxviruses, specifically monkeypox, such as the development of diagnostic tools.

Leptospirosis is a perplexing conundrum for many. In the existing literature, the pathophysiological mechanisms pertaining to leptospirosis is still not understood in full. Considered as a neglected tropical zoonotic disease, leptospirosis is culminating as a serious problem worldwide, seemingly exi...sting as co-infections with various other unrelated diseases, including dengue and malaria. Misdiagnosis is also common as non-specific symptoms are documented extensively in the literature. This can easily lead to death, as the severe form of leptospirosis (Weil’s disease) manifests as a complex of systemic complications, especially renal failure. The virulence of Leptospira sp. is usually attributed to the outer membrane proteins, including LipL32. With an armament of virulence factors at their disposal, their ability to easily adhere, invade and replicate within cells calls for a swift refinement in research progress to establish their exact pathophysiological framework. As an effort to reconstitute the current knowledge on leptospirosis, the basis of leptospiral infection, including its risk factors, classification, morphology, transmission, pathogenesis, co-infections and clinical manifestations are highlighted in this review. The various diagnostic techniques are also outlined with emphasis on their respective pros and cons.

Any individual that meets the suspected case definition of monkeypox should be offered testing in appropriately equipped laboratories by staff trained in the relevant technical and safety procedures. Confirmation of monkeypox virus infection is based on nucleic acid amplification testing (NAAT), usi...ng real-time or conventional polymerase chain reaction (PCR), for detection of unique sequences of viral DNA. PCR can be used alone, or in combination with sequencing. The recommended specimen type for laboratory confirmation of monkeypox is skin lesion material, including swabs of lesion surface and/or exudate, roofs from more than one lesion, or lesion crusts.

Interim rapid response guidance, 10 June 2022.
It includes considerations for certain populations such as patients with mild disease with considerations for community care, patients with moderate to severe disease, sexually active persons, pregnant or breastfeeding women, children and young persons.... The guidance also addresses considerations for clinical management such as the use of therapeutics, nutritional support, mental health services, and post-infection follow-up.
The document provides guidance for clinicians, health facility managers, health workers and infection prevention and control practitioners including but not limited to those working in primary care clinics, sexual health clinics, emergency departments, infectious diseases clinics, genitourinary clinics, dermatology clinics, maternity services, paediatrics, obstetrics and gynaecology and acute care facilities that provide care for patients with suspected or confirmed monkeypox

Nach dem derzeitigen Informationsstand sind aktuell humane Infektionen durch das Affenpockenvirus (monkeypox virus, MPX) in einigen Regionen der Welt einschließlich mehreren europäischen Ländern aufgetreten. Die Daten belegen eine Mensch-zu-Mensch-Übertragung unter bestimmten Bedingungen. Die Ü...bertragung von MPX von Mensch zu Mensch erfolgt in der Regel durch engen Haut- bzw. Schleimhautkontakt mit infektiösem Material aus den Hautläsionen einer infizierten Person, sowie – seltener – durch respiratorische Tröpfchen/Sekrete z.B. bei längerem Kontakt von Angesicht zu Angesicht oder durch kontaminierte Gegenstände und Oberflächen. Bei diesem Erreger ist besonders zu beachten, dass Partikel des Affenpockenvirus eingebettet in Sekreten bzw. getrocknet an Hautschuppen bzw. Schorfpartikeln für längere Zeiträume infektiös sein können, was eine sorgfältige und umfassende Reinigung und Desinfektion der Patientenumgebung bzw. der Oberflächen notwendig macht.

This document provides information and recommendations for action, based on the current available knowledge around monkeypox. It is a first draft which will be updated in light of evolving evidence and additional information as they become available.
The goal of the global outbreak response for monkeypox is to stop human-to-human transmission of monkeypox, with a priority focus on communities at high risk of exposure which may differ according to context, and to effectively use strong public health measures to prevent onward spread of the diseas...e. Judicious use of vaccines can support this response. This interim guidance, developed with the advice and support of the Strategic Advisory Group of Experts (SAGE) Working Group on smallpox and monkeypox vaccines, provides the first WHO recommendations on vaccines and immunization for monkeypox. Key points follow.
