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.

Over the past 50 years, dengue has spread from nine to over a hundred countries, making it the most rapidly spreading vector-borne disease. Yet, dengue continues to have a low profile among policy-makers and donors and does not receive the media attention it deserves. While there is no vaccine or cu...re for dengue, it can be managed and prevented. We need a renewed commitment to integrated programming that includes improved management and diagnosis, increased awareness and community participation in controlling the vector and enhanced environmental sanitation

Interim Guidance, published 11 January 2021.
The cold chain is necessary to prevent damage to vaccines caused by heat exposure. However, improper use of cold chain equipment may cause damage to freeze-sensitive vaccines (i.e. those vaccines containing alum adjuvant or oil-emulsion adjuvant). Studie...s conducted in several countries with hot and cold climates show frequent occurrences of sub-zero temperatures in the cold chain. The most common cause of exposure to freezing temperature is the failure to correctly condition ice packs prior to transport. Vaccines that are inadvertently frozen lose potency, increase wastage rates and increase the risk of adverse events following immunization (AEFI). Vaccine carriers protect vaccine potency during immunization sessions and transport to outreach sites. This guidance document is intended to help inform which type of vaccine carrier to select based on local context, to maintain vaccine quality, especially at service delivery points.
