Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

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.

Providing quality, stigma-free services is essential to equitable health care for all and achieving global HIV goals and broader Sustainable Development Goals related to health. Every person has the right to the highest attainable standard of physical and mental health. Countries have a legal obliga...tion to develop and implement legislation and policies that guarantee universal access to quality health services and address the root causes of health disparities, including poverty, stigma and discrimination.
The health sector is uniquely placed to lead in addressing inequity, assuring safe personcentred care for everyone and improving social determinants of health by overcoming taboos and discriminatory or stigmatizing behaviours associated with HIV, viral hepatitis and sexually transmitted infections (STIs). Improving health care quality and reducing stigma work together to enhance health outcomes for people living with HIV. Together, they make health care services more accessible, trustworthy and supportive. This encourages early diagnosis, consistent treatment and improved mental well-being. Thus, people living with HIV are more likely to engage with and benefit from health care services, leading to improved overall health.

Technical Update
Areas of Africa endemic for Buruli ulcer (BU), caused by Mycobacterium ulcerans, also have a high prevalence of human immunodeficiency virus (HIV), with adult prevalence rates between 1% and 5% (Maps). However, there is limited information on the prevalence of BU–HIV coinfection.... Preliminary
evidence suggests that HIV infection may increase the risk of BU disease (1–3). In the Médecins Sans Frontières project in Akonolinga, Cameroon, HIV prevalence was approximately 3–6 times higher among BU patients than the regional estimated HIV prevalence (2). Similarly in Benin and Ghana, BU
patients were 8 times and 3 times respectively more likely to have HIV infection than those without BU (1, 3). Further study is needed to clarify this association and enhance knowledge about the prevalence ofBU–HIV coinfection in endemic areas.

In recent years, Rwanda has been on the fast track to achieve major health improvements for its entire population. With the support of government agencies and various non-governmental partners, the Ministry of Health (MoH) has endeavored to decentralize Rwanda’s health system and bring health serv...ices closer to the people. Guided by multitude of national and international development frameworks, Rwanda’s healthcare successes include the establishment of a community health insurance scheme (mutuelle de santé), a system of cooperative-financed community health workers in every village, and interventions for researching, preventing, and treating diseases like HIV/AIDS, TB, and malaria.
As the MoH continues to design innovative means to reach and surpass its prescribed health outcome targets, it will hold as core principles the integration of service provision, the increase in healthcare capacity, and the attainment of sustainable funding sources. Rwanda is committed to achieving the Millennium Development Goals by 2015 and has declared Family Planning (FP) a national priority for poverty reduction and socioeconomic development of the country. Modern contraceptive use has more than quadrupled from 2005 to 2010, rising from 10% to 45%, but the government’s Economic Development and Poverty Reduction Strategy calls for an increase the modern contraceptive prevalence to 70% by 2016. While structural changes in health care and supply chains have led to noteworthy improvements in FP and other services, there are still many challenges that must be overcome. As such, a strategic plan is needed to coordinate FP efforts around a well-defined set of objectives and responsibilities.

The main goal of the National Health Plan (NHP) 2017-2021 is to extend access to a basic Essential Package of Health Services (EPHS) to the entire population while increasing financial protection. In order to extend service delivery to all communities, the NHP calls for all health workers (whether c...ommunity-based, outreach-based or facility-based) involved in the delivery of health promotion, prevention and treatment services to be fully recognised and institutionalized within the health system to ensure efficient use of resources, necessary oversight and quality service provision (regardless of whether the health workers are voluntary or salaried). The first year Annual Operational Plan (AOP) of the NHP 2017-2021 calls for a comprehensive literature review of the situation of all Village Based Health Workers (VBHWs) in the country to inform the development of a comprehensive, institutionalized approach to community health for the country.

In 1964 medical mission was challenged and called to define its distinctiveness and its special role in the context of that particular time. The consultation "Tuebingen I" clearly stated: "The Christian church has a specific task in the field of health and healing"1, and developed a conce...pt of wholeness and of the role of the congregation in health provision. 50 years later, the question of the proprium of Christian health services is again a very important one. At a time when governments, international non-governmental organizations and other philanthropic organizations participate in health care, the question has to be asked: What is the specific contribution of a Christian health service or ministry of healing? At a time when chronic disease challenges not only rich but now also poor countries, when infections like Ebola that for years were hidden in Africa pose a threat to the global situation, Christians have to reflect on the question of the proprium of Christian health care.

The number of COVID-19 cases is on the rise again, with South Africa nearing half of all confirmed cases in the WHO African Region. Threats of new variants loom and low vaccination coverage raises questions on the future of the response to COVID-19. Prevention remains the key strategy in most sub-Sa...haran countries. Five National Centres (NCs) from the African Health Observatory Platform on Health Systems and Policies (AHOP), based in Ethiopia, Kenya, Nigeria, Rwanda and Senegal, reflect on lessons to be learnt from their containment responses in the initial phases. They construct timelines to highlight the policies and challenges associated with introducing a range of public health containment measures and
discuss the extent to which these measures continue to be valuable given the ever-changing nature of the pandemic.

Access to safe blood and blood products is recognized as one of the key requirements for delivery of modern health care in the journey towards health for all. The foundation of safe and sustainable blood supplies depends on the collection of blood from voluntary non-remunerated and low-risk donors. ...Data from the WHO Global Database for Blood Safety (GDBS) brings out several inadequacies related to the supply and safety of blood and blood products. These inadequacies include a number of variations in safe blood practices across the world, including the quantity of blood donated (voluntary and replacement types), quality and adequate testing of the donated blood (immunohaematology [IH] and transfusion-transmitted infections [TTIs]), rational use of blood and blood components such as appropriate patient blood management protocols. These variations are very high in countries of the South-East Asian Region and most of them are either low- or middle-income countries (LMICs).
