Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the ...terms ‘airborne’, ‘airborne transmission’ and ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

A role for nuclear techniques
Antimicrobials play a critical role in the treatment of human and animal (aquatic and terrestrial) diseases, which has led to their widespread application and use. Antimicrobial resistance (AMR) is the ability of micro...organisms to stop an antibiotic, such as an antimicrobial, antiviral or antimalarial, from working against them. Globally, about 700 000 deaths per year arise from resistant infections as a result of the fact that antimicrobial drugs have become less effective at killing resistant pathogens. Antimicrobial chemicals that are present in environmental compartments can trigger the development of AMR. These chemicals can also cause antibiotic-resistant bacteria (ARB) to further spread antibiotic resistance genes (ARG) because they may have an evolutionary advantage over non-resistant bacteria.

In Kenya, the bacterial infections that contribute most to human disease are often those in which re-‐sistance is most evident. Examples are multidrug-‐resistant enteric ... bacterial pathogens such as typhoid, diarrhoeagenic Escherichia coli and invasive non-‐typhi salmonella, penicillin-‐resistant Streptococcus pneu-‐moniae, vancomycin-‐resistant enterococci, methicillin-‐resistant Staphylococcus aureus and multidrug-‐re-‐sistant Mycobacterium tuberculosis. Resistance to medicines commonly used to treat malaria is of particu-‐lar concern, as is the emerging resistance to anti-‐HIV drugs. Often, more expensive medicines are required to treat these infections, and this becomes a major challenge in resource-‐poor settings.

There is paucity of data on the burden and specific drivers operative in the pathogenesis of chronic obstructive pulmonary disease (COPD) in the African setting and populations. Lack of awareness and inadequate knowledge on the aetio-...tribute-to-highlight medbox">pathogenesis of the disease together with inadequate capacity for COPD care contributes to preventive and management challenges. Thus, the majority of patients with COPD are misdiagnosed, misclassified and mismanaged or undertreated. With the struggling improvement in the quality of healthcare in Africa, studies conducted over the last 10 years indicates the rising trends in both the risk factors and the burden of COPD. The role of new risk factors such as indoor pollution, infections with human immunodeficiency virus (HIV) and pulmonary tuberculosis (TB), in the pathogenesis of COPD in Africa is increasingly being recognized. This literature review attempts to collect and synthesize information that could be useful in improving COPD care and informing the governments to take appropriate actions for prevention, diagnosis and management of COPD in Africa.

During fresh fruit and vegetables (FFV) production, water is used for a variety of purposes. Even the water was conventionally treated and disinfected, it may still potentially contain human pathogens...n>, albeit at low concentrations. A risk assessment, appropriate to the national or local production context, should be conducted to assess the potential risks associated with a specific water source or supply in order to devise the appropriate risk mitigation strategies.
Since the 48th session of Codex Committee on Food Hygiene (CCFH) noted the importance of water safety and quality in food production and processing, FAO and WHO has undertaken the work on this subject. This report describes the output of the third in a series of meetings, which examined appropriate and fit-for-purpose microbiological criteria for water used with fresh fruit and vegetables. The advice herein will support decision making when applying the concept of fit-for-purpose water for use in the pre- and post-harvest production of fresh fruit and vegetables.

This short paper aims to identify key evidence gaps in our knowledge of livestock- and fisheries-linked antimicrobial resistance in the developing world, and to document on-going or planned research initiatives on this topic by key stakeholders.
The antimicrobial resistant (AMR) infections in anima...ls that are of most potential risk to human health are likely to be zoonotic pathogens transmitted through food, especially Salmonella and Campylobacter. In addition, livestock associated methicillin resistant Staphylococcus aureus (LA MRSA) and extended spectrum beta lactamase E. coli (ESBL E. coli) are emerging problems throughout the world.

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.

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

Climate change refers to long-term shifts in weather conditions and patterns of extreme weather events. It may lead to changes in health threat to human beings, multiplying existing hea...lth problems. This review examines the scientific evidences on the impact of climate change on human infectious diseases. It identifies research progress and gaps on how human society may respond to, adapt to, and prepare for the related changes. Based on a survey of related publications between 1990 and 2015, the terms used for literature selection reflect three aspects — the components of infectious diseases, climate variables, and selected infectious diseases. Humans' vulnerability to the potential health impacts by climate change is evident in literature. As an active agent, human beings may control the related health effects that may be effectively controlled through adopting proactive measures, including better understanding of the climate change patterns and of the compound disease-specific health effects, and effective allocation of technologies and resources to promote healthy lifestyles and public awareness. The following adaptation measures are recommended: 1) to go beyond empirical observations of the association between climate change and infectious diseases and develop more scientific explanations, 2) to improve the prediction of spatial–temporal process of climate change and the associated shifts in infectious diseases at various spatial and temporal scales, and 3) to establish locally effective early warning systems for the health effects of predicated climate change.
