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.

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.

Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In the Americas, CD creates the greatest burden in disability-adjusted life years of any parasitic infection. In Co...lombia, 437 000 people are infected with T. cruzi, of whom 131 000 suffer from cardiomyopathy. Colombia’s annual costs for treating patients with advanced CD reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development of cardiomyopathy—and costs just US$ 30 per patient—fewer than 1% of people with CD in Colombia and elsewhere receive it.

Multiple pandemics, numerous outbreaks, thousands of lives lost and billions of dollars of national income wiped out—all since the turn of this century, in barely 17 years—and yet the world’s investments in pandemic preparedness and response remain woefully inadequate. We know by now that the ...world will see another pandemic in the not-too-distant future; that random mutations occur often enough in microbes that help them survive and adapt; that new pathogens will inevitably find a way to break through our defenses; and that there is the increased potential for intentional or accidental release of a synthesized agent. Every expert commentary and every analysis in recent years tells us that the costs of inaction are immense. And yet, as
the havoc caused by the last outbreak turns into a fading memory, we become complacent and relegate the case for investing in preparedness on a back burner, only to bring it to the forefront when the next outbreak occurs. The result is that the world remains scarily vulnerable.

Antimicrobials are medicines, including antibiotics, antivirals, antifungals, and antiparasitics, that are used to prevent and treat infections in humans, animals, and plants. Antimicrobial Resistance (AMR) arises when bacteria, viruses, fungi, and parasites no longer respond to these medicines, ren...dering them ineffective and making infections more difficult to treat. This resistance increases the risk of disease spread, severe illness, disability, and death. Although AMR is a natural phenomenon driven by genetic
changes in pathogens, it is significantly accelerated by human activities such as the misuse and overuse of antimicrobials in healthcare, agriculture, and animal husbandry.

The document focuses on household water treatment methods to ensure access to safe drinking water, particularly in areas with limited access to clean water sources. It highlights the importance of safe water, noting that contaminated water is a major cause of waterborne diseases such as diarrhea and... cholera. Treating water at the household level is emphasized as an effective way to reduce health risks.
The document outlines several treatment methods, including boiling, which kills most pathogens; chlorination, which disinfects water by adding chlorine; filtration, which removes dirt and certain microbes using simple or advanced filters; and solar disinfection (SODIS), which involves exposing water in clear plastic bottles to sunlight for several hours to kill microbes. Additionally, it stresses the importance of safe water storage, such as using clean and covered containers to prevent recontamination, and practicing good hygiene, including regular handwashing and maintaining cleanliness around water sources.
By promoting these methods, the document aims to raise awareness and provide practical solutions for improving water quality at the household level, thereby reducing the spread of diseases and enhancing public health.

Antimicrobial resistance is one of the most important threats to the health worldwide. Antimicrobial resistance or drug resistance is the reduction of the pharmaceutical effects of a drug against a disease or reduction of its effectiveness in improving the clinical signs of a disease. Antimicrobial ...resistance occurs naturally but misuse of antibiotics in human and animals significantly accelerates the process of developing antimicrobial resistance. In fact, antimicrobial resistance refers to the resistance of a microorganism to one or more antimicrobial drugs which had been previously sensitive to these drugs. Antimicrobial resistance can occur in a wide variety of pathogens including bacteria, parasites, viruses, fungi, and cancer cells and may threaten the life of every person, in every age, and in every country

Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum. This disease is highly endemic in some regions of North America, Central America, and South America and is also reported in certain countries of Asia and Africa. It often affects people with impaired immunity, including people ...living with HIV, among whom the most frequent clinical presentation is disseminated histoplasmosis. The symptoms of disseminated histoplasmosis are non-specific and may be indistinguishable from those of other infectious diseases, especially disseminated tuberculosis (TB), thus complicating diagnosis and treatment. Histoplasmosis is one of the most frequent opportunistic infections caused by fungal pathogens among people living with HIV in the Americas and may be responsible for 5–15% of AIDS-related deaths every year in this Region. These guidelines aim to provide recommendations for the diagnosis, treatment, and management of disseminated histoplasmosis in persons living with HIV

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.

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.

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.
