This infographic from the Tropeninstitut illustrates the malaria transmission cycle. It begins when an Anopheles mosquito bites a human and injects its sporozoites into the bloodstream. The sporozoites then travel to the liver where they mature and release merozoites back into the bloodstream. The m...erozoites then infect red blood cells, resulting in the clinical symptoms of malaria. Some merozoites develop into gametocytes, which can be ingested by another mosquito when it bites the infected person again, thus continuing the transmission cycle.
The infographic serves as an educational tool, helping to explain the complex life cycle of the malaria parasite and the role of mosquitoes in spreading the disease.

PHSM are vital in reducing the risk and scale of infectious disease transmission and lowering hospitalization and deaths. Examples include contact tracing, quarantine and isolation, mask use, ventilation, school or workplace measures, mobility restrictions and travel requirements.
While these mea...sures are essential, decision-making on PHSM becomes particularly complex during rapidly evolving health emergencies, with incomplete information and under significant public and political pressure, especially when the pathogen is novel or poorly understood. In such contexts, guidance needs to be agile and responsive, developed and adapted based on emerging evidence and shifting epidemiological patterns. Decision-makers are frequently confronted with difficult trade-offs, having to balance measures that are:
─ effective but socially disruptive;
─ cost-effective but logistically burdensome;
─ beneficial for public health but economically disruptive; or
─ practical but inequitable or unethical

The report provides an update on the cholera outbreak in Haiti as of January and February 2024. A total of 79,411 suspected cases have been reported, with 4,608 confirmed cases and 1,172 deaths across all 10 departments. The most affected regions include Ouest, Centre, Artibonite, and Nord, with chi...ldren aged 1-9 being the most impacted. Despite a recent decline in reported cases, underreporting due to security issues remains a concern. Response efforts include coordination meetings, epidemiological surveillance, case management, WASH interventions, vaccination campaigns, and community engagement. However, logistical challenges, insecurity, and funding shortages are hindering effective response efforts.

For thousands of years, humans have been using wildlife for commercial and subsistence purposes. Wildlife trade takes place at local, national and international levels, with different forms of wildlife, such as live animals, partly processed products and finished products. Wildlife is a vital source... of safe and nutritious food, clothing, medicine, and other products, in addition to having religious and cultural value. Wildlife trade also contributes to livelihoods, income generation and overall economic development.
However, wildlife trade can have detrimental effects on species conservation, depleting natural resources, impoverishing biodiversity and degrading ecosystems (Morton et al., 2021). Wildlife trade, whether legal or illegal, regulated or unregulated, can pose threats to animal health and welfare. It also presents opportunities for zoonotic pathogens to spill over between wildlife and domestic animals, and for diseases to emerge with serious consequences for public or animal health and profound economic impacts (IPBES, 2020; Swift et al., 2007; Smith et al., 2009; Gortazar et al., 2014; Stephen, 2021; Stephen et al., 2022; FAO, 2020). The risk of pathogen spillover and disease emergence is amplified with increased interaction between humans, wildlife and domestic animals. The risk of pathogen spillover has also been exacerbated by climate change, intensified agriculture and livestock production, deforestation, and other land-use changes. Wildlife trade is also a risk to ecosystem biodiversity via the introduction of invasive species (Wikramanayake et al., 2021). Therefore, increased effort must be put into understanding the potential consequences of the wildlife trade, mapping and analysing the adjacent risks, and implementing strategies to manage those risks. Reducing wildlife-trade risks not only helps to limit disease but also minimises the negative effects of invasive species. Between 1960 and 2021, invasive alien species caused estimated cumulative damage of around 116 billion euros across 39 countries in the European Union alone, despite strict import regulations (Haubrock et al., 2021). The effect of invasive species is extremely apparent.

Effective malaria case management requires quick access to diagnostics and antimalarial treatments to reduce illness and death. Artemisinin-based combination therapy (ACT) has been essential to malaria treatment since 2001, as it combines artemisinin for rapid parasite reduction with a partner drug ...to ensure complete cure. However, resistance to antimalarial drugs, where parasites survive standard doses, threatens malaria control.

La página de la Organización Mundial de la Salud (OMS) sobre las enfermedades diarreicas destaca que son la tercera causa de muerte en niños de 1 a 59 meses, causando aproximadamente 443 832 muertes anuales en menores de 5 años. Estas enfermedades, aunque prevenibles y tratables, representan un...a de las principales causas de malnutrición infantil. La diarrea, definida como la evacuación de heces sueltas o líquidas tres o más veces al día, suele ser síntoma de infecciones intestinales transmitidas por alimentos o agua contaminados, o por una higiene deficiente. La prevención incluye el acceso a agua potable, saneamiento adecuado, lavado de manos con jabón, lactancia materna exclusiva durante los primeros seis meses y vacunación contra el rotavirus. El tratamiento se basa en la rehidratación oral con soluciones de sales de rehidratación oral (SRO) y suplementos de zinc. La OMS trabaja con los Estados Miembros para promover políticas que apoyen el manejo de estas enfermedades y mejoren el acceso a agua potable y saneamiento.

- The goal of diagnostic testing for Ebola and Marburg virus diseases is to identify cases to provide timely and appropriate care and to stop disease transmission.
- All individuals meeting the case definition for Ebola or Marburg virus diseases should be tested.
- The recommended sample type ...for testing for orthoebolaviruses and orthomarburgviruses is whole blood or plasma for living patients, and oral swab for deceased individuals.
- Laboratory confirmation of Orthoebolavirus and Orthomarburgvirus infections and further species identification should be done using nucleic acid amplification testing (NAAT).
- If a suspected case tests negative (living patient) and the blood was drawn less than 72 hours after symptom onset, a second test should be performed with blood drawn more than 72 hours after symptom onset.
- All manipulations in laboratory settings of samples originating from suspected, probable or confirmed cases of Ebola and Marburg virus diseases should be conducted with appropriate biosafety measures according to a risk-based approach.
- Whole or partial genome sequencing can be used to characterize viruses and complement epidemiologic investigations.
- Member States are strongly encouraged to share genetic sequence data (GSD) in publicly accessible databases.
- Member States are required to immediately notify the World Health Organization (WHO) under the International Health Regulations (IHR) 2005 of positive laboratory results.

The Mediclinic article on silicosis provides an overview of this occupational lung disease caused by inhaling silica dust. It explains that inhaled silica particles lead to lung scarring and nodule formation, progressively impairing breathing. The article outlines symptoms such as shortness of breat...h, severe cough, fatigue, loss of appetite, chest pains, and fever. Diagnosis involves a medical examination, detailed occupational history, lung function tests, and imaging like chest X-rays or CT scans to detect lung scarring and nodules. While silicosis is irreversible with no specific cure, management focuses on preventing further silica exposure and treating complications. Preventive measures include maintaining high occupational health standards to control silica dust exposure.
