Vaccines are powerful weapons in the fight against pandemic viruses as shown by responses to both the 2009 H1N1 influenza and the COVID-19 pandemics. However, planning for accessing, allocating and deploying vaccines in a pandemic situation is a complex endeavour, beset with multiple challenges at a...ll levels – local, regional and global. The World Health Organization (WHO) and its partners have prepared this revised guidance document to assist countries update their national deployment and vaccination plans (NDVPs) by leveraging global learnings from past pandemic responses, including the recent COVID-19 vaccination effort. The development and testing of a NDVP would not only advance pandemic preparedness efforts but would also have benefits in terms of increasing national capabilities to manage other health emergencies which require emergency vaccination campaigns.

There is increasing interest in understanding the role of air pollution as one of the greatest threats to human health worldwide. Nine of 10 individuals breathe air with polluted compounds that have a great impact on lung tissue. The nature of the relationship is complex, and new or updated data are... constantly being reported in the literature. The goal of our review was to summarize the most important air pollutants and their impact on the main respiratory diseases (chronic obstructive pulmonary disease, asthma, lung cancer, idiopathic pulmonary fibrosis, respiratory infections, bronchiectasis, tuberculosis) to reduce both short- and the long-term exposure consequences. We considered the most important air pollutants, including sulfur dioxide, nitrogen dioxide, carbon monoxide, volatile organic compounds, ozone, particulate matter and biomass smoke, and observed their impact on pulmonary pathologies. We focused on respiratory pathologies, because air pollution potentiates the increase in respiratory diseases, and the evidence that air pollutants have a detrimental effect is growing. It is imperative to constantly improve policy initiatives on air quality in both high- and low-income countries.

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.

A erradicação da varíola humana (mpox em inglês) foi certificada em 1980. A varíola símia (mpox em inglês) é endêmica nos países da África Central e Ocidental desde a sua primeira detecção, em 1958. Trata-se de uma zoonose cujos casos geralmente ocorrem perto de florestas tropicais, ond...e diversos animais são portadores do ortopoxvírus causador da doença. A maioria das infecções em seres humanos pelo vírus da varíola símia em países onde a doença é endêmica é resultado de transmissão primária de animais para humanos. A transmissão de pessoa a pessoa pode ocorrer por meio de contato próximo com secreções respiratórias ou lesões cutâneas de uma pessoa infectada ou com objetos recém-contaminados. A transmissão também pode ocorrer através da placenta da mãe para o feto ou por contato direto durante ou após o parto. Até 21 de maio de 2022, 12 países onde não há varíola símia endêmica, em 2 regiões da Organização Mundial da Saúde (OMS), haviam notificado 92 casos confirmados da doença. Até 26 de agosto de 2022, 96 países sem endemicidade, de todas as 6 regiões da OMS, haviam notificado 45.198 casos confirmados de varíola símia, incluindo 6 óbitos. No mesmo período, os países onde a doença é endêmica notificaram 350 casos confirmados e 6 óbitos. Na Região das Américas, 29 países e territórios notificaram 23.479 (48%) casos confirmados e 3 óbitos. Diversos estudos observacionais sobre as vacinas de primeira geração demonstraram que a eficácia da vacinação contra a varíola humana na prevenção da varíola símia é de aproximadamente 85%. Atualmente, as vacinas originais (de primeira geração) contra a varíola humana não estão mais disponíveis.

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

Language influences the way we think, how we perceive reality, and how we behave. With respect to HIV, language can embody stigma and discrimination, which impacts access to testing, acquisition of HIV, and engagement with treatment. Language plays a role in supporting respect and empowerment of ind...ividuals, as communities shape how they are referred to and the labels they wish to use. Consideration and use of appropriate language can strengthen the global response to the HIV pandemic by diminishing stigma and discrimination and increasing support and understanding for individuals and communities living with HIV.

Asthma is the most common chronic respiratory disease (CRD) worldwide and is estimated to affect 262 million causing significant mortality and morbidity, and has emerged as an important public health problem in many Latin American (LA) countries over the last 30 or so years. LA is a highly diverse r...egion in terms of geography, climate, wealth, and ethnicity including 20 different countries with 639 million inhabitants, where 40 million are estimated to have asthma. A common feature of LA countries is the high level of social inequalities3 (Figure 1). In LA, asthma prevalence in both children and adults is highly variable and, where high, is among the highest worldwide, particularly in coastal tropical cities.

Silicosis is not a new disease; the impact of silica dust on respiratory function was observed by Hippocrates in 430 B.C. and in the 16th century by Agricol. In 1713, Rammazini described silicotic nodules in post-mortems of stone cutters presenting with respiratory symptoms. In the mid-late 1800s,... the introduction of mechanized tools in the mining sector rapidly increased levels of silica exposure, resulting in an increase in cases and our understanding of silicosis.
