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 intention of this handbook on integrated vector management (IVM) is to provide
guidance to the managers of vector-borne disease control programmes, including
comparable officials in health and other sectors involved in vector-borne disease control.
The target audience is managers and official...s at central, district and lower administrative
levels. The handbook provides background information to complement the Core structure
for training curricula on integrated vector management and associated training materials.
A separate document, Guidance on policy-making for integrated vector management,

The purpose of this document is to provide guidance on the use of pooled sample testing strategy in coronavirus disease (COVID-19)
testing laboratories of the African Union Member States for scaling up SARS-CoV-2 nucleic acid testing capacity with the available resources. The current document descr...ibes the effect of factors such as the prevalence of COVID-19 in the population to be tested, the homogeneity of pools, and the sensitivity of the molecular test in optimal pool size determination. It also highlights the importance of monitoring the prevalence of COVID-19 in a population to be tested and proper validation of the test, to limit the potential for false-negative results. Validation studies to determine the optimal pool size by testing laboratories are recommended as the optimum approach. A safe, simple ‘two-stage pooling’ option has been indicated in this guidance to be used by laboratories until such validation can be achieved.

Indoor residual spraying (IRS) involves applying residual insecticide to potential vector resting sites on the interior surfaces of human dwellings or other buildings. The main aim of IRS is to kill vectors before they are able to transmit pathogens to humans. When carried out correctly, IRS has his...torically been shown to be a powerful intervention to reduce adult vector density and longevity for mosquitoes, sand flies and triatomine bugs and can reduce the transmission of vector-borne diseases.

Licensed pharmaceutical products (marketing authorization) should be manufactured only by licensed manufacturers (holders of a manufacturing authorization) whose activities are regularly inspected by competent national authorities. This guide to GMP shall be used as a standard to justify GMP status,... which constitutes one of the elements of the WHO Certification Scheme on the quality of pharmaceutical products moving in international commerce, through the assessment of applications for manufacturing authorizations and as a basis for the inspection of manufacturing facilities. It may also be used as training material for government medicines inspectors, as well as for production, QC and QA personnel in the industry

Development assistance for health (DAH)
plays a vital role in supporting health programmes in lowand middle-income countries. While DAH has historically
focused on infectious diseases and maternal and child
health, there is a lack of comprehensive analysis of DAH
trends, strategic shifts and the...ir impact on health systems
and outcomes. This study aims to provide a comprehensive
review of DAH from 1990 to 2022, examining its evolution
and funding allocation shifts.

WHO recommends artemisinin-based combination therapies for treating uncomplicated malaria, alongside studies to monitor treatment effectiveness. Given the threat of antimalarial resistance, including partial resistance in several African countries, molecular tools are vital for tracking resistance. ...In 2015, WHO launched the External Quality Assessment scheme for nucleic acid amplification testing to ensure reliable lab results. Coordinated by WHO and operated by the United Kingdom National External Quality Assessment Service for Parasitology, the scheme provides quality-controlled specimens and reports to help improve testing accuracy. Experts recently discussed expanding the scheme to include antimalarial resistance markers.
