Onchocerciasis causes skin and eye disease, visual impairment and neurological problems. It is mostly found in Africa, but also in Latin America and Yemen. The common name, ‘river blindness,’ gives a good indication where the disease can be found: the vector of the parasite, a small black fly of... the Simulium species, breeds in rivers where there is turbulence in the water, such as rapids, or where the flow is disturbed by overhanging vegetation.

Chagas disease caused by Trypanosoma cruzi is a public health issue in Latin America. This highly diverse parasite is divided into at least seven discrete typing units (DTUs) TcI-TcVI and Tcbat. Some DTUs have been associated with geographical distribution in epidemiological scenarios and clinical m...anifestations, but these aspects remain poorly understood. Many studies have focused on studying the parasite and its vectors/hosts, using a wide variety of genetic markers and methods. Here, we performed a systematic review of the literature for the last 20 years to present an update of DTUs distribution in the Americas, collecting ecoepidemiological information. We found that the DTUs are widespread across the continent and that there is a whole gamma of genetic markers used for the identification and genotyping of the parasite. The data obtained in this descriptor could improve the molecular epidemiology studies of Chagas disease in endemic regions.

Planning for public health emergencies should ensure that capabilities developed during previous emergencies are maintained, incorporated, and put into practice when a new event of public health concern arises. Investments in pandemic preparedness lead to more rapid detection and a stronger response... to public health threats, thereby shielding communities from the debilitating social and economic effects of epidemics and pandemics. The Pan American Health Organization (PAHO) recognizes the efforts of countries in the Region of the Americas to develop and/or strengthen their respiratory pathogen pandemic plans. PAHO supports planning activities with tools and expertise, aligning these efforts with the Preparedness and Resilience for Emerging Threats (PRET) initiative. The PRET initiative is an innovative approach to improving disease pandemic preparedness. It recognizes that the same systems, capacities, knowledge, and tools can be leveraged and applied for groups of pathogens based on their mode of transmission (respiratory, vector-borne, foodborne etc.). The PRET initiative incorporates the latest tools and approaches for shared learning and collective action established during the COVID-19 pandemic and other recent public health emergencies.

The conditionality of this recommendation is largely driven by the current higher unit cost of pyrethroid-PBO ITNs compared
to pyrethroid-only LLINs and therefore the uncertainty of their cost-effectiveness. Furthermore, as PBO is less wash-resistant
than pyrethroids, its bioavailability declines ...faster over the three-year estimated life of an ITN; therefore, the added impact of
pyrethroid-PBO ITNs over that of pyrethroid-only LLINs may decline over time. The evidence comes from two sites in
eastern Africa with pyrethroid resistance and not from other geographies where transmission levels and vector characteristics
may vary. PBO acts by inhibiting certain metabolic enzymes, primarily oxidases, and so are likely to provide greater protection
than pyrethroid-only LLINs where mosquitoes display mono-oxygenase-based insecticide resistance mechanisms.

The presentation titled "Malaria Capacity Building Initiative" outlines efforts led by the WHO and partner organizations to strengthen the skills and systems needed to fight malaria globally. It highlights the need for a coordinated, long-term strategy to build human resource capacity in malaria-end...emic countries—especially among national malaria control programs, frontline health workers, NGOs, and WHO staff. The document reviews past and current training activities, such as workshops on case management, entomology, vector control, epidemiology, and planning. It emphasizes the development of standardized training materials and competency frameworks, the role of national and regional training centers, and the use of blended learning methods (e.g., e-learning and in-person sessions). The goal is not just to deliver training, but to build sustainable capacity through partnerships, continuous improvement, quality assurance, and integration into health systems. It also calls for better coordination, tracking of trained personnel, and engagement of ministries of finance to ensure long-term support.

The National Strategic Plan for Malaria Elimination 2021–2025 outlines Bangladesh’s roadmap to achieve zero indigenous malaria cases by 2030, with an interim goal to reduce transmission to near-zero levels by 2025. The strategy builds upon earlier successes in malaria control and shifts focus to...ward elimination in both high- and low-endemic areas.
The plan emphasizes five core objectives: ensuring universal access to quality malaria prevention and treatment services, strengthening surveillance and case detection systems, improving vector control through long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS), building community engagement, and enhancing program governance and accountability.
High-priority districts, especially in the Chittagong Hill Tracts, are targeted for intensified interventions, including active case detection and tailored outreach to mobile and vulnerable populations. The strategy also calls for robust health systems support, cross-border collaboration, and integration of malaria services into broader primary health care.
This document serves as Bangladesh’s strategic foundation to transition from malaria control to phased elimination, in line with national and global targets.

Access to safe, effective and quality-assured health products and technologies is crucial for achieving universal health coverage and primary health care goals. The continued growth of the aging population; increasing burden of noncommunicable diseases; growing burden of mental health issues; climat...e change; shifting patterns of vector borne diseases, fungal disease and waterborne diseases; antimicrobial resistance; and new infectious hazards create an ongoing need for equitable access to safe, effective and quality-assured health products and technologies, and renewed investments in research and development for innovative health products and technologies.
The coronavirus pandemic exposed the inequalities in access to health products, highlighting the need for longer-term strategies to strengthen access to health products and technologies outside of and in emergency situations. While technological and scientific advances present an opportunity to increase access to health products and technologies, the risk of increasing inequality due to higher prices for new health products and technologies; the persisting problem of substandard and falsified medical products; a lack of skilled workforce in many low- and middle-income countries; and a lack of data for decisionmaking and for measuring progress present significant challenges.

A century after its discovery, Chagas' disease still represents a major public health challenge in Latin America. Moreover, because of growing population movements, an increasing number of cases of imported Chagas' disease have now been detected in non-endemic areas, such as North America and some E...uropean countries. This parasitic zoonosis, caused by Trypanosoma cruzi, is transmitted to humans by infected Triatominae insects, or occasionally by non-vectorial mechanisms, such as blood transfusion, mother to fetus, or oral ingestion of materials contaminated with parasites. Following the acute phase of the infection, untreated individuals enter a chronic phase that is initially asymptomatic or clinically unapparent. Usually, a few decades later, 40-50% of patients develop progressive cardiomyopathy and/or motility disturbances of the oesophagus and colon. In the last decades several interventions targeting primary, secondary and tertiary prevention of Chagas' disease have been attempted. While control of both vectorial and blood transfusion transmission of T cruzi (primary prevention) has been successful in many regions of Latin America, early detection and aetiological treatment of asymptomatic subjects with Chagas' disease (secondary prevention) have been largely underutilised. At the same time, in patients with established chronic disease, several pharmacological and non-pharmacological interventions are currently available and have been increasingly used with the intention of preventing or delaying complications of the disease (tertiary prevention). In this review we discuss in detail each of these issues.
