Dengue is a mosquito-borne viral disease that occurs mainly in the tropics and subtropics but has a high potential to spread to new areas. Dengue infections are climate sensitive, so it is important to better understand how changing climate factors affect the potential for geographic spread and futu...re dengue epidemics. Vectorial capacity (VC) describes a vector's propensity to transmit dengue taking into account human, virus, and vector interactions. VC is highly temperature dependent, but most dengue models only take mean temperature values into account. Recent evidence shows that diurnal temperature range (DTR) plays an important role in influencing the behavior of the primary dengue vector Aedes aegypti. In this study, we used relative VC to estimate dengue epidemic potential (DEP) based on the temperature and DTR dependence of the parameters of A. aegypti. We found a strong temperature dependence of DEP; it peaked at a mean temperature of 29.3°C when DTR was 0°C and at 20°C when DTR was 20°C. Increasing average temperatures up to 29°C led to an increased DEP, but temperatures above 29°C reduced DEP. In tropical areas where the mean temperatures are close to 29°C, a small DTR increased DEP while a large DTR reduced it. In cold to temperate or extremely hot climates where the mean temperatures are far from 29°C, increasing DTR was associated with increasing DEP. Incorporating these findings using historical and predicted temperature and DTR over a two hundred year period (1901-2099), we found an increasing trend of global DEP in temperate regions. Small increases in DEP were observed over the last 100 years and large increases are expected by the end of this century in temperate Northern Hemisphere regions using climate change projections. These findings illustrate the importance of including DTR when mapping DEP based on VC.

Since 2000, concerted efforts by national programmes, supported by public–private partnerships, nongovernmental organizations, donors and academia under the auspices and coordination of the World Health Organization (WHO), have produced important achievements in the control of human African trypan...osomiasis (HAT). As a consequence, the disease was targeted for elimination as a public health problem by 2020. The Sixty-sixth World Health Assembly endorsed this goal in resolution WHA66.12 on neglected tropical diseases, adopted in 2013.
National sleeping sickness control programmes (NSSCPs) are core to progressing control of the disease and in adapting to the different epidemiological situations. The involvement of different partners, as well as the support and trust of long-term donors, has been crucial for the achievements.

This report presents examples from different agencies on how they approached community engagement in their Covid-19 responses, the tools and methodologies used, as well as the challenges they encountered and how they attempted to overcome these. It discusses what community engagement means to the va...rious agencies interviewed and in the literature consulted. And it puts forward some reflections on how CCCM and other sector agencies can take steps to ensure community participation in this and future pandemic responses.

The Region of the Americas comprises 46 countries and territories and Brazil and Peru are among the WHO high- TB burden
countries. T o illustrate the recent increase in TB incidence in the region, we selected 12 countries from Latin America (Argentina,
Brazil, Chile, Colombia, Ecuador, El Salvador..., Mexico, Panama, Paraguay, Peru, Uruguay and Venezuela), which account for approximately 80% of the total estimated TB cases in the region.

The objectives of these guidelines are to provide recommendations outlining a public health approach to managing people presenting with advanced HIV disease, and to provide guidance on the timing of initiation of antiretroviral therapy (ART) for all people living with HIV.
WHO recommends that a... package of screening, prophylaxis, rapid ART initiation and intensified adherence interventions be offered to everyone living with HIV presenting with advanced disease.
WHO strongly recommends that rapid ART initiation should be offered to people living with HIV following confirmed diagnosis and clinical assessment. Rapid initiation of ART is defined as within seven days of HIV diagnosis. WHO further strongly recommends ART initiation on the same day as HIV diagnosis based on the person’s willingness and readiness to start ART immediately, unless there are clinical reasons to delay treatment.

Universal health coverage ensures everyone has access to the health services they need without suffering financial hardship as a result. In December 2012, a UN resolution was passed encouraging governments to move towards providing universal access to affordable and quality health care services. As ...countries move towards it, common challenges are emerging -- challenges to which research can help provide answers.

The South African WHO Country Cooperation Strategy (CCS) 2023–2027 focuses on four key strategic priorities based on the country’s health needs and disease epidemiology, while also considering the need for building resilient health systems for UHC and health security in the post pandemic period....
These include:
1. augment health systems strengthening reforms to accelerate progress towards universal health coverage.
2. address the quadruple burden of diseases and promote well-being across the life course in view of achieving global targets.
3. build health systems resilience and strengthen health emergency preparedness and response capacities.
4. enhance multisectoral collaboration and global partnerships for concerted action on health and its determinants.
In order to harness its expertise across its three levels, namely: the WHO Country Office (WCO), WHO Regional Office for Africa, and WHO headquarters, WHO will work closely and collaboratively with the Government of South Africa to implement the 2023–2027 strategic priorities.
