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.

A Focus on the Journey to Self-Reliance for Preventing Child and Maternal Deaths . June 2018
The 2018 Acting on the Call report focuses on 25 countries’ journeys to self-reliance for preventing child and maternal deaths. Self-reliance is a country’s ability to finance and implement solution...s to its own development challenges. Understanding where countries lie on this effort - known as the journey to self-reliance - helps USAID to best partner with countries and support their efforts.
The report looks at the health status of 25 priority countries as well as the current capacity of the health system to meet the needs of women and children. In the report, we recount progress since the 2012 Call to Action as well as identify gaps in order to inform future programming and areas that need strengthening during the journey to self-reliance. For the first time ever, we’ve calculated the return on our investment to eliminate bottlenecks to improving health services.
