This version of Field Trials of Health Interventions includes seven new chapters on conducting systematic literature reviews, trial
governance, preliminary studies and pilot testing, budgeting and accounting, intervention costing and economic analysis, and Phase IV studies. Before new interventions... are released into disease control programmes, it is essential that they are carefully evaluated in ‘field trials’. These may be complex and expensive undertakings, requiring the follow-up of hundreds, or thousands, of individuals, often for long periods. This manual was designed to provide guidance on the practical issues in great detail

As the number of transboundary pest and animal and foodborne disease outbreaks rises, so does the number of people who are chronically hungry due to these and other factors. The correlation can be explained by the link between our health and that of the planet. We rely on land and sea for the produc...tion of safe and quality foods for our daily nourishment. Pests and disease epidemics negatively impact the quality, quantity and safety of our food sources, and cripple economic growth and efficiencies in production. Furthermore, the epidemic and endemic levels of the pathogens and disease vectors can be difficult to control. This is why FAO stresses and promotes the special efforts required for cost-effective preventive measures rather than the more expensive control, disinfestation, treatment and disposal measures. When preventive measures are late or difficult, preparedness and contingency plans must be in place to enable rapid response. Early warning systems, based on close monitoring, surveillance, and timely reporting are fundamental to warn and empower communities to safeguard their livelihoods and assets by enhancing disease and pest prevention measures and for government services to take immediate measures to protect communities and national economies.

The Cholera Q&A Fact Sheet provides essential information about cholera, including its causes, symptoms, treatment, and prevention. Cholera is an acute diarrheal disease caused by Vibrio cholerae, which spreads through contaminated water and food. It leads to rapid dehydration and can be fatal if un...treated. Symptoms range from mild diarrhea to severe dehydration, shock, and death.
Treatment primarily involves Oral Rehydration Therapy (ORT) to replace lost fluids, and in severe cases, intravenous fluids. Antibiotics are generally not recommended for mass treatment. Prevention focuses on safe drinking water, sanitation, hand hygiene, and proper food handling.
The document also discusses cholera vaccination, with three WHO-approved oral vaccines available. However, vaccines should be used alongside other control measures. The Global Task Force on Cholera Control (GTFCC) aims to eliminate cholera transmission in 20 countries by 2030 through improved sanitation, vaccination, and rapid outbreak response.

These consolidated guidelines on HIV testing services (HTS) bring together existing and new guidance on HTS across different settings and populations.
The World Health Organization (WHO) first released consolidated guidelines on HTS in 2015, in response to requests from Member States, national pr...ogramme managers and health workers for support to achieve the United Nations (UN) 90–90–90 global HIV targets – and specifically the first target of diagnosing 90% of all people with HIV. In 2016, based on new evidence, WHO released a supplement to address important new HIV testing approaches – HIV self-testing (HIVST) and provider-assisted referral.
Since the release of 2015 and 2016 HTS guidelines, new issues and more evidence have emerged. To address this, WHO has updated guidance on HIV testing services. In this guideline, WHO updates recommendation on HIVST and provides new recommendations on social network-based HIV testing approaches and western blotting (see box, next page). This guideline seeks to provide support to Member States, programme managers, health workers and other stakeholders seeking to achieve national and international goals to end the HIV epidemic as a public health threat by 2030.
These guidelines also provide operational guidance on HTS demand creation and messaging; implementation considerations for priority populations; HIV testing strategies for diagnosis HIV; optimizing the use of dual HIV/syphilis rapid diagnostic tests; and considerations for strategic planning and rationalizing resources such as optimal time points for maternal retesting

Human African trypanosomiasis (HAT) has been an alarming global public health issue. The disease affects mainly poor and marginalized people in low-resource settings and is caused by two subspecies of haemoflagellate parasite, Trypanosoma brucei and transmitted by tsetse flies. Progress made in HAT ...control during the past decade has prompted increasing global dialogue on its elimination and eradication. The disease is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2020 and to terminate its transmission globally by 2030, along-side other Neglected Tropical Diseases (NTD). Several methods have been used to control tsetse flies and the disease transmitted by them. Old and new tools to control the disease are available with constraints.
Currently, there are no vaccines available. Efforts towards intervention to control the disease over the past decade have seen considerable progress and remarkable success with incidence dropping progressively, reversing the upward trend of reported cases. This gives credence in a real progress in its elimination. This study reviews various control measures, progress and a highlight of control issues, vector and parasite barriers that may have been hindering progress towards its elimination.

Prevention, early diagnosis, and effective treatment are essential for the control and elimination of Neisseria gonorrhoeae as a public health problem. Currently, in Latin America and the Caribbean, treatment for gonorrhea infection is largely empiric and based on clinical diagnosis. In the Americas..., the high burden of new N. gonorrhoeae infections (estimated at 11 million new cases a year), the complexity of the disease epidemiology, and in many countries the limited resources, make it difficult to fully understand the burden of disease and the burden of antimicrobial resistance (AMR) in N. gonorrhoeae.
PAHO has developed this document to facilitate the navigation of available guidance and recommendations for N. gonorrhoeae AMR surveillance by public health and health care professionals, at the national and subnational levels, involved in designing, implementing, and/or strengthening AMR surveillance of N. gonorrhoeae and overall surveillance of sexually transmitted infections.

SARS-CoV-2 infections among children and adolescents cause less severe illness and fewer deaths compared to adults. While a less severe course of infection is a positive outcome, there are concerns that mild symptoms may have led to less testing, resulting in fewer identified cases of COVID-19 in ch...ildren. If children with mild or no symptoms transmit the disease, they may act as drivers of transmission within their communities. Understanding symptoms, infectivity and patterns of SARS-CoV-2 transmission in children and adolescents is essential for developing, adapting and improving control measures for COVID-19 across all ages. This is a summary of the current knowledge around SARS-CoV-2 infection acquisition and transmission and COVID-19 disease symptoms in children and adolescents. It aims to inform decisions, based on local contexts, on how to best keep schools, kindergarten and day-care facilities open and what advice to apply to intergenerational mixing.

Since 2000, concerted efforts by national programmes, supported by public–private partnerships, nongovernmental organizations, donors and academia under the auspices and coordination of the World Health Organization (WHO), have produced important achievements in the control of human African trypan...osomiasis (HAT). As a consequence, the disease was targeted for elimination as a public health problem by 2020. The Sixty-sixth World Health Assembly endorsed this goal in resolution WHA66.12 on neglected tropical diseases, adopted in 2013.
National sleeping sickness control programmes (NSSCPs) are core to progressing control of the disease and in adapting to the different epidemiological situations. The involvement of different partners, as well as the support and trust of long-term donors, has been crucial for the achievements.

The WHO Laboratory Biosafety Manual (LBM) has been in broad use at all levels of clinical and public health laboratories, and other biomedical sectors globally, serving as a de facto global standard that presents best practices and sets trends in biosafety.
LBM encouraged countries t...o accept and implement basic concepts in biological safety and to develop national codes of practice for the safe handling of biological agents in laboratories within their geographical borders.
This fourth edition of the manual builds on the risk assessment framework introduced in the third edition. A thorough, evidence-based and transparent assessment of the risks allows safety measures to be balanced with the actual risk of working with biological agents on a case-by-case basis.
This novel evidence- and risk-based approach will allow optimised resource use and sustainable laboratory biosafety and biosecurity policies and practices that are relevant to their individual circumstances and priorities, enabling equitable access to clinical and public health laboratory tests and biomedical research opportunities without compromising safety.

Antibiotics and other antimicrobial agents are invaluable life savers, particularly in resource-limited countries where infectious diseases are abundant. Both uncomplicated and severe infections are potentially curable as long as the aetiological agents are susceptible to the ...antimicrobial drugs. The rapid rate with which antimicrobial agents are becoming ineffective due to resistance acquired as a result of unchecked overuse and misuse threatens to undo the benefit of controlling infections. The evidence for resistant microorganisms, many times to more than a single antimicrobial agent, has been observed globally. In Tanzania, there is evidence in the form of few scattered studies conducted in different parts of the country in a multitude of settings including health care facilities, the community, domesticated animals and wild animals
