Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

This module is part of the WHO series The Immunological Basis for Immunization, which was initially developed in 1993 as a set of eight modules, comprising one module on general immunology and seven modules each devoted to one of the vaccines recommended for the Expanded Programme on Immunization, i....e. vaccines against diphtheria, measles, pertussis, polio, tetanus, tuberculosis and yellow fever. Since then, this series has been updated and extended to include other vaccines of international importance. The main purpose of the modules is to provide national immunization managers and vaccination professionals with an overview of the scientific basis of vaccination against a range of important infectious diseases. The modules developed since 1993 continue to be vaccine-specific, reflecting the biological differences in immune responses to the individual pathogens and the differing strategies employed to create the best possible level of protection that can be provided by vaccination. The modules also serve as a record of the immunological basis for the WHO recommendations on vaccine use, published in the WHO vaccine position papers.*

Deuxième d’une série consacrée à la prévention de la thrombose associée au cancer (Cancer-Associated Thrombosis, ou CAT en anglais), le présent article a pour but d’améliorer l’enseignement aux patients et leur état de santé. Le premier article, intitulé « Importance de la thromboe...mbolie veineuse liée au cancer », expliquait la pathologie ainsi que les lacunes cernées dans les connaissances des patients atteints de cancer (Sardo, Bayadinova, Jenkins et Penton, 2021). Il mettait en lumière le fait que ces patients reçoivent très peu d’information sur le risque de thromboembolie veineuse (TEV). Les stratégies proposées dans le présent article visent à sensibiliser les patients atteints de cancer à la TEV, à fournir des outils d’enseignement aux patients et, en fin de compte, à réduire le fardeau de la thrombose associée au cancer.

Community-based interventions are vital for facilitating poststroke recovery, increasing community participation, and raising awareness about stroke survivors. To optimize recovery and community reintegration, there is a need to understand research findings on community-based interventions that focu...s on stroke survivors and their caregivers. Although nurses and community health workers (CHWs) are commonly involved in community-based interventions, less is known about their roles relative to other poststroke rehabilitation professionals (physical therapists, occupational therapists, and speech-language pathologists). Thus, the purpose of this review is to explore research focused on improving community-based stroke recovery for adult stroke survivors, caregivers, or both when delivered by nurses or CHWs.

Eight years after Super Typhoon Haiyan, the most destructive storm to ever hit the Philippines, Super Typhoon Rai brought similar torrential rains, violent winds, mudslides, floods and storm surges to central parts of the Philippines, leaving a wide path of destruction and debris in its wake. While ...not as powerful as Haiyan in terms of wind strength, evidence shows that Rai damaged houses, infrastructure and livelihoods on a comparable scale or in even greater numbers. Most striking, Rai damaged 1.57 million homes, 500,000 more than Haiyan, across 11 of the Philippines 17 regions, with around 180,000-200,000 people still displaced – either still in evacuation centers or staying with friends, family or other temporary housing.

WHO and Psyon Games have joined forces to launch a new tower defense game called the Antidote COVID-19 to turn complex, scientific information into a fun learning experience. During the course of the game, players will learn about their immune system, pathogens, vaccines and how to protect themselve...s from COVID-19.
The game comes at a critical point of the pandemic where misinformation is hindering COVID-19 vaccine acceptance and adherence to other public health measures due to fear, mistrust and doubt. By putting players in the driver’s seat, the game urges everyone to play a role in fighting harmful misinformation online, and learning and sharing the facts from trusted sources of information.
The game starts just before the pandemic begins. The player is recruited to halt the spread of SARS-COV-2, the virus that causes COVID-19, by developing vaccines and helping the human immune system fight off the virus. Based on real events, this online adventure takes the player to the frontline of science, ultimately providing lifesaving information in the palms of their hands.

The report demonstrates that the current system—at both national and international levels— was not adequate to protect people from COVID-19. The time it t...ook from the reporting of a cluster of cases of pneumonia of unknown origin in mid-late December 2019 to a Public Health Emergency of International Concern being declared was too long. February 2020 was also a lost month when many more countries could have taken steps to contain the spread of SARS-CoV-2 and forestall the global health, social, and economic catastrophe that continues its grip. The Panel finds that the system as it stands now is clearly unfit to prevent another novel and highly infectious pathogen, which could emerge at any time, from developing into a pandemic.

To avoid a reversal of progress from the adverse impacts of the COVID-19 pandemic, new knowledge and lessons from successful programmatic innovations are urgently needed to improve TB prevention and care. Experience can provide evidence for innovative approaches and strategies to mainta...in and scale up high-quality TB services. WHO therefore called for case studies on programmatic innovations that address emerging challenges in TB prevention and care during the pandemic in order to collect and disseminate the findings to the TB community. Between November 2020 and February 2021, a total of 23 case studies relevant to the call were accepted from 19 countries in the six regions of WHO. The lessons learnt from these country activities to ensure the continuity of essential services like TB care in the face of the crippling crisis may also inform strategies for minimizing the impact of future emerging pathogens on health services.
