Chikungunya virus (CHIKV) is currently one of the most relevant arboviruses to public health. It is a member of the Togaviridae family and alphavirus genus and causes an arthritogenic disease known as chikungunya fever (CHIKF). It is characterized by a multifaceted disease, which is distinguished fr...om other arbovirus infections by the intense and debilitating arthralgia that can last for months or years in some individuals. Despite the great social and economic burden caused by CHIKV infection, there is no vaccine or specific antiviral drugs currently available. Recent outbreaks have shown a change in the severity profile of the disease in which atypical and severe manifestation lead to hundreds of deaths, reinforcing the necessity to understand the replication and pathogenesis processes. CHIKF is a complex disease resultant from the infection of a plethora of cell types. Although there are several in vivo models for studying CHIKV infection, none of them reproduces integrally the disease signature observed in humans, which is a challenge for vaccine and drug development. Therefore, understanding the potentials and limitations of the state-of-the-art experimental models is imperative to advance in the field. In this context, the present review outlines the present knowledge on CHIKV epidemiology, replication, pathogenesis, and immunity and also brings a critical perspective on the current in vitro and in vivo state-of-the-art experimental models of CHIKF.

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

We combine data on Chinese development projects with data from Demographic and Health Surveys to study the impact of Chinese aid on household welfare in sub-Saharan Africa. We use a novel methodology to test the effect of Chinese aid on three important development outcomes: education, health, and nu...trition. For each outcome, we use difference-in-difference estimations to compare household areas near Chinese project sites to control areas located farther away, before and after receiving Chinese aid. This empirical strategy rules out many confounding factors that can bias measuring the impact of Chinese aid on our outcome variables. First, we find that Chinese projects significantly improve education and child mortality in treatment areas, but do not significantly affect nutrition. Second, social sector projects have a larger effect on outcomes than economic projects. Third, we do not find significant effects for projects that ended more than five years before the post-treatment survey wave. Our results are robust to a host of robustness checks.

Against the backdrop of the COVID-19 pandemic, health is receiving unprecedented public and political attention. Yet the fact that climate change also presents us with a health crisis deserves further recognition. From more deaths due to heat stress to increased transmission of infectious diseases, ...climate change affects the social and environmental determinants of health in ways that are profound and far-reaching. The fundamental interdependency of human health and the health of the environment is encapsulated in the concept of planetary health, a scientific field and social movement that has been gaining force since the 2015 publication of the Rockefeller Foundation-Lancet Commission report “Safeguarding human health in the Anthropocene epoch”.
We see an urgent need for strategic communication to raise awareness of climate-health synergies in order to overcome the misperception that climate and health are two independent agendas. The fragmented and sector-focused nature of thinking and action remains a significant barrier to integrating health considerations into climate planning and project development. Inevitably, collaboration across sectors requires a community of practice. Despite recent efforts focused on the climate-health nexus, much work remains to be done to translate scientific findings for policymakers, mobilise climate financing resources in support of health co-benefits, and promote genderjust solutions within climate change projects.

The scale of West Africa’s Ebola epidemic has been attributed to the weak health systems of affected countries,
their lack of resources, the mobility of communities and their inexperience in dealing with Ebola. This briefing for African Affairs argues that these explanations lack important contex...t. The briefing examines responses to the outbreak and offers a different set of explanations, rooted in the history of the region and the political economy of global health and development. To move past technical discussions of “weak” health systems, it highlights how structural violence has contributed to the epidemic. As part of this, local people – their beliefs, concerns and priorities – have been marginalised. Both the crisis response and post-Ebola ‘reconstruction’ will be strengthened by acknowledgment of its long term structural underpinnings and from a more collaborative inclusion of local people.
