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 marathon to eradicate polio is on its final lap: the world is more than 99% of the way to success. After millennia of living with poliovirus and suffering the paralysis it causes, today nearly all the world’s people live in polio-free countries; two of the three strains of wild poliovirus (WPV...) have been eradicated. Some 20 million people are walking who would have been paralysed had it not been for the efforts of national governments and health workers. If eradicating polio has been a marathon, the finishing line is in sight.

The purpose of this Operational Guideline is to support state health authorities, programme managers and health care professionals with recommendations on appropriate management of children with SAM in the health facilities. Facility based management includes setting up and managing within the healt...h facility premises, a functional space where these children are cared for. This Facility Based Unit is referred to as Nutritional Rehabilitation Centre or NRC in the document. While the scale and design may vary in a given situation, it is intended that the document provide the basis for a consistent set of principles that can be used by all states for facility based management of children with SAM. The Operational Guideline focuses on the Facility/Hospital based approach for the management of SAM children under 5 years of age based on the WHO and revised IAP protocols.

New data from the WHO reveal that an estimated 2.2 billion cases of malaria and 12.7 million deaths have been averted since 2000, but the disease remains a serious global health threat, particularly in the WHO African Region. According to WHO’s latest World malaria report, there were an estimated ...263 million cases and 597 000 malaria deaths worldwide in 2023. This represents about 11 million more cases in 2023 compared to 2022, and nearly the same number of deaths. Approximately 95% of the deaths occurred in the WHO African Region, where many at risk still lack access to the services they need to prevent, detect and treat the disease.

This interim guidance is for LTCF managers and corresponding infection prevention and control (IPC) focal persons in LTCF and updates the guidance published in March 2020. The objective of this document is to provide guidance on IPC in LTCFs in the context of COVID-19 to 1) prevent COVID-19-virus fr...om entering the facility and spreading within the facility, and 2) to support safe conditions for visiting through the rigorous application of IPC procedures for the residents’ well-being. WHO will update these recommendations as new information becomes available.

This WHO laboratory manual provides the most up to date methods and procedures for the laboratory identification of yellow fever virus infection in humans. It provides guidance on the establishment and maintenance of an effective laboratory providing routine surveillance testing for yellow fever, wh...ich operates within the WHO coordinated Global Yellow Fever Laboratory Network (GYFLaN) capable of providing confirmation of yellow fever infection reliably and timely. This second edition supersedes the first edition of the 2004 WHO manual for the monitoring of yellow fever virus infection.

The combined effects from ambient (outdoor) air pollution and indoor (household, in particular) air pollution cause approximately 7 million premature deaths every year, largely as a result of increased mortality from stroke, IHD, COPD, lung cancer and acute respiratory infections (1). Air pollution ...can occur in both the outdoor and indoor environments. Cook-stoves in homes, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Air pollutants with the strongest evidence for adverse health outcomes include particulate matter (PM; both PM 2.5 (i.e. particles with an aerodynamic diameter
equal to or less than 2.5 μm) and PM10 (i.e. particles with an aerodynamic diameter equal to or less than 10 μm), ozone (O 3), nitrogen dioxide (NO 2 ), sulfur dioxide (SO 2 ) and carbon monoxide (CO). Air pollution is however composed of many more pollutants (1).
