Recent efforts to fight malaria in the Greater Mekong Subregion (GMS) have yielded impressive results. According to the latest WHO estimates, the six GMS countries cut their malaria case incidence by an estimated 54% between 2012 and 2015. Malaria death rates fell by 84% over the same period.
I...n May 2015, GMS Ministers of Health adopted the WHO Strategy for malaria elimination in the Greater Mekong Subregion 2015-2030. Urging immediate action, the plan aims to eliminate P. falciparum malaria from the subregion by 2025 and all species of human malaria by 2030.

The emergence of COVID-19 has drawn the attention of health researchers sharply back to the role that food systems can play in generating human disease burden. But emerging pandemic threats are just one dimension of the complex relationship between agriculture... and infectious disease, which is evolving rapidly, particularly in low-income and middle-income countries (LMICs) that are undergoing rapid food system transformation. This changing relationship is examined through four current disease issues.

Early detection, assessment and response to acute public health events:
Mem Inst Oswaldo Cruz , Rio de Janeiro, Vol. 110 (3): 377-386, May 2015
Response to the tropical cyclone in southern Africa
Ebola virus disease outbreak in the Democratic Republic of the Congo
Meningitis outbreak in Togo
Lassa fever outbreak in Liberia.
Sleeping sickness is controlled by case detection and treatment but this often only reaches less than 75% of the population. Vector control is capable of completely interrupting HAT transmission but is not used because of expense. We conducted a full scale field trial of a refined vector control tec...hnology. From preliminary trials we determined the number of insecticidal tiny targets required to control tsetse populations by more than 90%. We then carried out a full scale, 500 km2 field trial covering two HAT foci in Northern Uganda (overall target density 5.7/km2). In 12 months tsetse populations declined by more than 90%. A mathematical model suggested that a 72% reduction in tsetse population is required to stop transmission in those settings. The Ugandan census suggests population density in the HAT foci is approximately 500 per km2. The estimated cost for a single round of active case detection (excluding treatment), covering 80% of the population, is US$433,333 (WHO figures). One year of vector control organised within country, which can completely stop HAT transmission, would cost US$42,700. The case for adding this new method of vector control to case detection and treatment is strong. We outline how such a component could be organised.

En 2015, 5,9 millions d'enfants de moins de cinq ans sont décédés (1). Les principales causes de mortalité infantile dans le monde sont la pneumonie, la prématurité, les complications durant l'accouchement, la septicémie néonatale, les anomalies congénitales, la diarrhée, les tra...umatismes accidentels et le paludisme (2). La plupart de ces maladies et de ces problèmes sont, du moins en partie, causés par l'environnement. On a estimé en 2012 que 26 % des décès infantiles et 25 % de la charge totale de morbidité des enfants de moins de cinq ans pourraient être évités par la réduction des risques environnement aux tels que la pollution de l'air, l'insalubrité de l'eau, les mauvaises conditions d'hygiène et d'assainissement ou les produits chimiques.

Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.

In 2015, 5.9 million children under age five died (1). The major causes of child deaths globally are pneumonia, prematurity, intrapartum-related complications, neonatal sepsis, congenital anomalies, diarrhoea, injuries and malaria (2). Most of these diseases and conditions are at least partially cau...sed by the environment. It was estimated in 2012 that 26% of childhood deaths and 25% of the total disease burden in children under five could be prevented through the reduction of environmental risks such as air pollution, unsafe water, sanitation and inadequate hygiene or chemicals.
