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 microorganisms to stop an antibiotic, such as an antimic...robial, 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.

BMZ Papier 1
Gesundheit ist nicht nur Voraussetzung für ein selbstbestimmtes Leben, sondern auch essenziell für die gesellschaftliche und nachhaltige wirtschaftliche Entwicklung in unseren Partnerländern. Die gegenwärtige COVID-19 Pandemie zeigt, welche Gefahren von Infektionskrankheiten ausge...-hen. Der Erreger der Pandemie SARS-CoV-2 gibt auch einen Hinweis auf die Bedeutung zoono-tischer, also zwischen Tier und Mensch übertragbarer, Krankheiten. Es ist zu erwarten, dass diese Art von Erregern in der Zukunft noch häufiger auftreten wird. Eine wachsende Weltbevölkerung, Klimawandel, steigende Mobilität, Vordringen des Menschen in bisher unberührte Lebensräume, industrielle Landwirtschaft und Nutztierhaltung sind Faktoren, die das Risiko für das Entstehen bzw. für eine schnelle Ausbreitung von Krankheitserregern erhöhen

Avec l’essor des traitements antirétroviraux (TAR) à base de dolutégravir (DTG) pour soigner les personnes vivant avec
le VIH dans le monde, il est important d’estimer la vitesse à laquelle la résistance acquise au DTG apparaît dans les
populations sous TAR. Bien que la résistance au DT...G ne soit pas apparue dans les populations naïves aux TAR incapables
de supprimer la charge virale dans les essais cliniques, certains éléments portent à croire que la résistance au
DTG peut émerger chez les personnes suivant des schémas thérapeutiques incluant le DTG. L’OMS recommande aux
pays qui étendent les TAR incluant le DTG d’accompagner ce déploiement d’une surveillance en routine de la pharmacorésistance

The Lancet Volume 390, Issue 10110p2397-2409November 25, 2017.
Human African trypanosomiasis (HAT), also called sleeping sickness, is a parasitic infection that almost invariably progresses to death, unless treatment is provided. HAT caused devastating epidemics during the 20th century. Thanks to ...sustained and coordinated efforts during the past 15 years the number of reported cases has fallen to a historic low. Fewer than 3,000 cases were reported in 2015, and the disease is targeted for elimination by the World Health Organization. Despite recent success, HAT still poses a heavy burden on the rural communities where this highly focal disease occurs, most notably in Central Africa. Since patients are also reported from non-endemic countries outside Africa, HAT should be considered in differential diagnosis for all travellers, tourists, migrants and expatriates who have visited or lived in endemic areas. In the absence of a vaccine, disease control relies on case detection and treatment, and vector control. Available drugs are sub-optimal, but ongoing clinical trials give hope for safer and simpler treatments.

Mpox is an emerging zoonotic disease caused by the mpox virus, a member of the Orthopoxvirus genus closely related to the variola virus that causes smallpox. Mpox was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research. The first human case was recorde...d in 1970 in the Democratic Republic of the Congo (DRC) during a period of intensified effort to eliminate smallpox and since then the infection has been reported in a number of African countries. Mpox can spread in humans through close contact, usually skin-to-skin contact, including sexual contact, with an infected person or animal, as well as with materials contaminated with the virus such as clothing, beddings and towels, and respiratory droplets in prolonged face to face contact. People remain infectious from the onset of symptoms until all the lesions have scabbed and healed. The virus may spread from infected animals through handling infected meat or through bites or scratches. Diagnosis is confirmed by polymerase chain reaction (PCR) testing of material from a lesion for the virus’s DNA. Two separate clades of the mpox virus are currently circulating in Africa: Clade I, which includes subclades Ia and Ib, and Clade II, comprising subclades IIa and IIb. Clade Ia and Clade Ib have been associated with ongoing human-to-human transmission and are presently responsible for outbreaks in the Democratic Republic of the Congo (DRC), while Clade Ib is also contributing to outbreaks in Burundi and other countries.
In 2022‒2023 mpox caused a global outbreak in over 110 countries, most of which had no previous history of the disease, primarily driven by human-to-human transmission of clade II through sexual contact. In just over a year, over 90,000 cases and 150 deaths were reported to the WHO. For the second time since 2022, mpox has been declared a global health emergency as the virus spreads rapidly across the African continent. On 13 Aug 2024, Africa CDC declared the ongoing mpox outbreak a Public Health Emergency of Continental Security (PHECS), marking the first such declaration by the agency since its inception in 2017.7 This declaration empowered the Africa CDC to lead and coordinate responses to the mpox outbreak across affected African countries. On August 14, 2024, the WHO declared the resurgence of mpox a Public Health Emergency of International Concern (PHEIC) emphasizing the need for coordinated international response.
As of August 2024, Mpox has expanded beyond its traditional endemic regions, with new cases reported in countries including Sweden, Thailand, the Philippines, and Pakistan. Sweden has confirmed its first case of Clade 1 variant, which has been rapidly spreading in Africa, particularly in DRC. The emergence of this new variant raises concerns about its potential for higher lethality and transmission rates outside Africa.

HIV-1 drug resistance (HIVDR) genotyping is an essential component of the WHO global HIVDR surveillance strategy. Plasma “gold standard” specimen type for HIVDR genotyping, but its use may not be feasible in rural, remote areas in low- and middle-income countries, since preparing and storing it ...require personnel and laboratory infrastructure that are often lacking. An alternative specimen type is dried blood spots (DBS), which can be made without special laboratory processing. DBS are more easily transported than plasma because they can be shipped at ambient temperature as non-hazardous materials using regular mail or courier services.

This situation analysis has gathered information about the current state of AMR, contributing factors and antimicrobial use in Zimbabwe from the human, animal, agricultural and environmental sectors. Data has been gathered from different sectors such as the general public, academia, the Ministry of ...Health and Child Care, the Ministry of Agriculture Mechanization and Irrigation Development and the Ministry of Environment, Water and Climate. It shows that AMR is a real concern in Zimbabwe and a threat to the health outcomes of humans, to the economic productivity of the livestock industry and a risk to the environment.

Faciliter l’accès aux soins de santé primaires et assurer une couverture sanitaire universelle à la population reste un défi de grande taille pour les pays en voie de développement. En effet malgré quelques efforts consentis ces dernières décennies, le problème d’accessibilité aux so...ins de santé est loin d’être résolu. Outre le problème épineux des ressources humaines s’ajoutent des difficultés liées à l’organisation et au fonctionnement des systèmes de santé, au financement des systèmes de santé, à la prestations de soins de qualité et à l’accès aux médicaments de base. Tous ceci ayant un impact désastreux sur la population notamment les plus pauvres qui n’arrivent plus à bénéficier de soins de qualité permettant d’obtenir une santé optimale.

COVID-19 Vaccines: 1 Safety Surveillance 2 Manual
While there is no indication that pregnant women have an increased susceptibility to infection with SARS-CoV-2, there is evidence that pregnancy may increase the risk of severe illness and mortality from COVID-19 disease in comparison with non-pregn...ant women of reproductive age. As seen with non-pregnant women, a high proportion of pregnant women have asymptomatic SARS-CoV-2 infection and severe disease is associated with recognized medical (e.g., high body-mass index (BMI), diabetes, pre-existing pulmonary or cardiac conditions) and social (e.g., social deprivation, ethnicity) risk factors. Pregnant women with symptomatic COVID-19 appear to have an increased risk of intensive care unit admission, mechanical ventilation and death in comparison with non-pregnant women of reproductive age, although the absolute risks remain low. COVID-19 may increase the risk of preterm birth, compared with pregnant women without COVID-19, although the evidence is inconclusive.
