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.

Practical Guideline for collaborative interventions
The revised guidelines present two major changes to existing guidelines: (A) there are now just 2 categories of pneumonia instead of 3 (“pneumonia” which is treated at home with oral amoxicillin and “severe pneumonia” which requires injectable antibiotics) and (B) oral amoxicillin replaces o...ral cotrimoxazole as first line treatment, preferably in 250mg dispersible tablet form, twice daily for five days which can be reduced to three days in low HIV settings.

La méningite est mortelle et débilitante ; elle frappe brutalement ; elle a de graves conséquences sanitaires, économiques et sociales et touche tous les âges de la vie dans tous les pays du monde. La méningite bactérienne peut être à l’origine d’épidémies, entraîner la mort dans les... 24 heures et un patient sur cinq peut rester handicapé à vie à la suite d’une infection. La plupart des cas et des décès dus à la méningite pourraient être évités par la vaccination mais les progrès obtenus pour la vaincre sont bien moins rapides que ceux réalisés contre d’autres maladies à prévention vaccinale.
