Sustaining HIV Community-led Responses: Technical guidelines for costing and budgeting
UNAIDS
(2026)
Community-led responses (CLRs) are a vital pillar of the HIV response and central to achieving national and global targets, including the 30-80-60 commitments outlined in the 2021 Political Declaration on HIV and AIDS. These guidelines provide practical, step-by-step methods for costing and budgetin
...
g community-led responses (CLRs), tailored to the unique features of CLRs. They are designed for use by community-led organizations (CLOs), their partners, national governments, policy-makers, donors, and researchers involved in planning, implementing, financing or evaluating CLRs that address HIV.

Between April 2018 and November 2020, the Democratic Republic of Congo (DRC) experienced its 11th Ebola virus disease (EVD) outbreak. Tanzania’s cross-border interactions with DRC through regular visitors, traders, and refugees are of concern, given the potential for further spread to neighboring
...
countries. This study aimed to estimate the risk of introducing EVD to Tanzania from DRC. National data for flights, boats, and car transport schedules from DRC to Tanzania covering the period of May 2018 to June 2019 were analyzed to describe population movement via land, port, and air travel and coupled with available surveillance data to model the risk of EVD entry. The land border crossing was considered the most frequently used means of travel and the most likely pathway of introducing EVD from DRC to Tanzania. High probabilities of introducing EVD from DRC to Tanzania through the assessed pathways were associated with the viability of the pathogen and low detection capacity at the ports of entry. This study provides important information regarding the elements contributing to the risk associated with the introduction of EBV in Tanzania. It also indicates that infected humans arriving via land are the most likely pathway of EBV entry, and therefore, mitigation strategies including land border surveillance should be strengthened.

This review article examines 42 years of Ebola virus disease (EVD) outbreaks in Sub-Saharan Africa, from 1976 to 2019. The authors analyze the epidemiology, geographical distribution, mortality rates, and response strategies associated with 34 Ebola outbreaks across 11 African countries. The review

identifies key challenges in controlling Ebola, including weak health systems, limited surveillance and laboratory capacity, sociocultural practices, environmental changes, and community mistrust. It also discusses advances in diagnostics, treatments, and vaccines, and emphasizes the importance of a One Health approach, community engagement, effective communication, and stronger healthcare systems to improve preparedness, prevention, and response to future Ebola outbreaks.

Ocean plastic pollution has reached crisis level: every minute, more than an entire garbage truck of plastic makes its way into the world’s oceans—roughly 11 million metric tons annually. While plastic waste presents an immediate threat to marine wildlife and ecosystems, this global challenge al

so has implications for major industries such as fishing and tourism, impacting the livelihoods of millions of people. The drivers and impacts of ocean plastic pollution also contribute to global challenges in food security, human health, and climate change.

Environmental Research Letters
Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha

ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.
