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.

The Committee discussed the implications for preparedness for smallpox-like events reflected by the ongoing COVID-19 pandemic. The Committee noted how quickly diagnostics and vaccines could be developed and deployed when resources and political will were abundant. This rapidity was also due to the f...act that the genetic sequence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had been shared worldwide. It was noted that in one country SARS-CoV-2 had been reconstructed in a laboratory from the viral genome sequence before the first case of COVID-19 had been reported, highlighting the benefits of synthetic biology technologies for accelerated development of diagnostics as well as the oft-described potential risks. Lessons learned about clinical care during the COVID-19 pandemic were also discussed.

Cases of monkeypox (MPX) acquired in the EU have recently been reported in nine EU Member States (Austria, Belgium, France, Germany, Italy, Portugal, Spain, Sweden, and the Netherlands).
Monkeypox (MPX) does not spread easily between people. Human-to-human transmission occurs through close contact ...with infectious material from skin lesions of an infected person, through respiratory droplets in prolonged face-to-face contact, and through fomites. The predominance, in the current outbreak, of diagnosed human MPX cases among men having sex with men (MSM), and the nature of the presenting lesions in some cases, suggest transmission occurred during sexual intercourse

The main purpose of the meeting was to review tsetse control tools, activities and their contribution to the elimination of gHAT and the monitoring thereof. Seven endemic countries provided reports on recent and ongoing vector control interventions at the national level (Angola, Cameroon, Côte d’...Ivoire, Chad, Democratic Republic of the Congo, Guinea and Uganda). Country reports focused on the in situations implementing and supporting vector control activities, the tools and the approaches in use, the coverage of the activities in space and time and their impacts on tsetse populations. Future perspectives for vector control in the respective countries were also discussed, including opportunities and challenges to sustainability.

On 15–16 December 2020, WHO and the Medicines for Malaria Venture co-convened a technical consultation to consider the preferred product characteristics (PPCs) for drugs used in malaria chemoprevention. The main goal of the technical consultation was to agree on the most important PPCs for drugs t...o protect populations from malaria (chemoprevention), while considering relevant measures of efficacy and the safety data needed to support WHO policy recommendations.

In collaboration with partners, the government of Ethiopia has successfully developed 10 years Hand Hygiene for All (HH4A) costed national roadmap- a country-wide approach to achieving sustainable and universal hand hygiene. On the occasion of the 2022 Global Hand Washing Day event ( Ethiopia is cel...ebrating the event for one month with different sessions), the national HH4A road map launched on the 4th of Nov 2022 in a high-level advocacy event in the presence of higher officials and partners. Action is set mainly on the need for a joint effort to mobilize resources for implementation, monitoring and documenting of lessons and best practices.

Since 1996, trachoma has been targeted for elimination as a public health problem worldwide. The active trachoma criterion for national elimination as a public health problem is a TF1–9 < 5%, sustained for at least two years in the absence of antibiotic mass drug administration (MDA), in each form...erly endemic EU. Using A, F and E, health ministries and their partners have made considerable progress towards achieving this criterion in formerly endemic EUs worldwide. In 2002, an estimated 1517 million people lived in EUs in which EU-wide implementation of the A, F and E components of SAFE were thought to be needed for the purposes of global elimination of trachoma as a public health problem; by June 2021, that number had fallen to 136.2 million, a 91% reduction. Approximately 85% of the 136.2 million people living in EUs needing A, F and E in June 2021 were in WHO’s African Region.

WHO needs US$2.54 billion to provide life-saving assistance to millions of people around the world facing health emergencies. WHO’s Health Emergency Appeal is a consolidation of WHO’s priorities and financial requirements for 2023 to carry out health interventions in emergency and humanitarian r...esponses. The number of people in need of humanitarian relief has increased by almost a quarter compared to 2022, to a record 339 million. WHO is responding to an unprecedented number of intersecting health emergencies: climate change-related disasters such as flooding in Pakistan and food insecurity across the Sahel in the greater Horn of Africa; the war in Ukraine; and the health impact of conflict in Yemen, Afghanistan, Syria and north eastern Ethiopia – all of these emergencies overlapping with the health system disruptions caused by the COVID-19 pandemic and outbreaks of measles, cholera, and other killers. Contributions to the appeal can be fully flexible, flexible across a region, or flexible within a country appeal.

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.
