Vector-borne diseases are responsible for 17% of the global burden of communicable diseases and more than 500 000 deaths annually. The ambitious global targets for the control of vector-borne diseases come in the context of the (re-)emergence of dis

eases, increasing resistances to insecticides and uncertainty related to the financing of global vector control efforts. The United Nations 2030 Agenda with its related Sustainable Development Goals (SDGs), the New Urban Agenda adopted at the United Nations Conference on Housing and Sustainable Urban Development (Habitat III)
in Quito in 2016 and WHO’s Global vector control response 2017–2030 (WHO, 2017a) emphasize the value of elevating multisectoral actions and strategies that extend beyond the health sector to the core of integrated vector control.
This policy brief underlines the important role housing conditions have in the transmission of vector-borne diseases and showcases interventions and policies the housing sector can contribute to effective, integrated and intersectoral vector-borne diseases management.

WHO has published the first-ever guidance on the clinical management of diphtheria. The only previously available guidance was an operational protocol. The new guidance followed the rigorous process for developing guidance at WHO.
It addresses the use of Diphtheria Antitoxin (DAT)
...
in the treatment of diphtheria. There is a worldwide shortage of DAT and evidence based recommendations on the use of DAT were requested by many Member States.
The guidance also includes new recommendations on antibiotics. In patients with suspected or confirmed diphtheria, WHO recommends using macrolide antibiotics (azithromycin, erythromycin) rather than penicillin antibiotics.
This clinical practice guideline has been rapidly developed recognizing the global increase in diphtheria outbreaks. Outbreaks of diphtheria in Nigeria, Guinea and neighbouring countries in 2023 have highlighted the urgent need for evidence-based clinical practice guidelines for the treatment of diphtheria. Given the sporadic nature of outbreaks, many clinicians in the affected regions have never managed acute diphtheria and its related complications. Diphtheria remains a neglected disease and vaccination is the top priority. At the same time, for patients with diphtheria, access to antibiotics, DAT and supportive care can be lifesaving.

This version (2024) of the WHO ERF has been developed following extensive consultation across the three levels of the Organization and response experiences over the last five years of emergency response. Key areas have been updated to improve the accountability, predictability, timeliness and effectiveness of WHO’s response to emergencies.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a
...
nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

Cervical cancer is the second most common cancer among women worldwide and causes a significant number of deaths in the South-East Asia Region. Nearly 200 000 new cases of cervical cancer occurred

in SEA Region Member States in 2008, giving an incidence of almost 25 per 100 000 and a mortality rate of almost 14 per 100 000. Cervical cancer can be prevented by early screening and vaccination. However, due to poor access to screening and treatment services, the vast majority of these deaths occur in women from nine Member States of the South-East Asia Region which account for more than one third of the global burden of cervical cancer.

After five consecutive below-average rains, the humanitarian crisis in the Horn of Africa is expanding and deepening.
Combined with insecurity and macroeconomic volatility, the impact of the drought on food and nutrition security has been devasta

ting. Across Ethiopia, Kenya and Somalia, an estimated 22 million people are now acutely food insecure because of the drought. The malnutrition situation is also critical. Some 5.1 million children across drought-affected areas of the three countries are acutely malnourished in 2023, with dire implications for their health, growth and survival. Concerningly, the upcoming March-May 2023 rains are also forecast to be below-average. Should these rains fail, and humanitarian assistance not be delivered at scale, food insecurity will continue to deteriorate.
Regardless of how the 2023 rains perform, extremely high humanitarian needs will persist through 2023 while a full recovery from a drought of this magnitude will take years. To address the devastating drought-induced hunger and malnutrition across the region, WFP is pursuing an integrated dual track approach; meeting immediate life-saving food and nutritional needs while simultaneously building resilience to extreme climate variability.
