Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

The WHO Cholera Vaccine Position Paper (August 2017) highlights the importance of oral cholera vaccines (OCVs) as a key tool in outbreak response and prevention, alongside water, sanitation, and hygiene (WASH) measures. It recommends OCVs for high-risk populations, endemic areas, and humanitarian cr...ises, emphasizing their effectiveness in reducing cases and mortality. The paper discusses two types of OCVs (Dukoral®, Shanchol™, Euvichol®) and supports the WHO-managed vaccine stockpile for rapid deployment in cholera-prone regions.

The standard operating procedures (SOP) for referral care cover all the refugee populations living in Lebanon. These SOPs outline the policies and procedures for referral care in Lebanon, including the limits in health assistance that can be provided.
Each year since 2007, G-FINDER has provided policy-makers, donors, researchers and industry with a comprehensive analysis of global investment into research and development of new products to
prevent, diagnose, control or cure neglected diseases in low- and middle-income countries, making it the go...ld standard in tracking and reporting global funding for neglected disease R&D. This year’s report, the sixteenth overall, focuses on investments made in participants’ 2022 financial year (‘FY2022’) and, for the first time, adds comprehensive coverage of the product pipeline in each disease area.

This Communication Guide for Malaria Control Interventions is aligned with Tanzania’s Malaria Strategic Plan (2015–2020) and provides comprehensive guidance on the implementation of Social and Behaviour Change Communication (SBCC) for the prevention, diagnosis and treatment of malaria. It is int...ended for all stakeholders and implementing partners, with the aim of ensuring harmonised messaging and coordinated communication efforts. The guide outlines strategies, key messages, communication channels and target audiences, with a focus on sustaining and improving malaria-related behaviours at the individual, family and community levels. It incorporates malaria stratification and supports the development of tailored SBCC interventions in different risk areas. Developed with contributions from the Ministry of Health and Social Welfare, the National Malaria Control Programme and various partner organisations, the guide aims to reduce the malaria burden and promote a malaria-free Tanzania. Supplemented by Standard Operating Procedures (SOPs), the guide serves as a practical tool for consistent and effective malaria communication nationwide.

This Implementation Kit (I-Kit), developed by the Health Communication Capacity Collaborative (HC3), which is funded by USAID and based at the Johns Hopkins Center for Communication Programs, offers structured guidance for improving social and behavioural change communication (SBCC) strategies relat...ed to malaria in pregnancy (MiP). Designed for programme managers and stakeholders, the toolkit addresses critical communication gaps in MiP programming, particularly among service providers. It provides tools to help users integrate MiP into situation analyses, segment audiences, define behavioural objectives and draft strategic communication plans.
MiP poses a significant public health challenge, contributing to maternal and neonatal mortality and morbidity in sub-Saharan Africa. Although effective interventions exist, such as the use of insecticide-treated nets, intermittent preventive treatment in pregnancy (IPTp) and timely diagnosis and treatment, their implementation remains inconsistent. The I-Kit supports more effective SBCC planning and implementation, with the aim of increasing the uptake and impact of these interventions and ultimately reducing malaria-related deaths and illness among pregnant women and newborns.

In line with the Defeating meningitis by 2030: a global road map, the WHO guidelines on meningitis diagnosis, treatment and care Executive Summary provides a summary of the evidence-based recommendations for the clinical management of children and adults with community-acquired meningitis, including... acute and long-term care. Meningitis poses a significant public health threat, despite successful efforts to control the disease globally. The burden of morbidity and mortality from meningitis remains high, particularly in low- and middle-income countries and in settings experiencing large-scale, disruptive epidemics.
