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.

Stenotrophomonas maltophiliais a nonfermenting Gram-negative rod that is ubiquitous in nature (predominantly occurring in aquatic environments and on plants). Biochemically, it iscatalase positive and oxidase negative, and it produces acid frommaltose (hence the name“maltophilia”). Due to it...s chargedcell wall surface and biofilm production, it may attach to and survive on abiotic surfaces in clinical settings (eg, central venouscatheters, disinfectant and hand-washing solutions, solutions for hemodialysis, endoscopes, inspiration/expiration circuits of ventilators, nebulizers, tap water, and showerheads).

Tsetse traps and targets (insecticide-impregnated screens) function by attracting the flies to a device that collects and/or kills them. Traps can be used for entomological surveillance, and also for control. Targets are simpler than traps, but are not used for surveillance. They are impregnated wit...h biodegradable insecticides in order to kill any flies that alight on them. Traps can also be impregnated with insecticides. Traps and targets can both be used to eliminate a fraction of the tsetse population.

Malaria remains a significant public health concern in the SADC region, accounting for 20% of childhood deaths, as well as prompting numerous outpatient visits and hospitalisations. Around three-quarters of the population, including 35 million children under the age of five and 8.5 million pregnant ...women, are at risk. Transmission patterns vary from high and stable in the north to malaria-free in the south, with low, unstable and seasonal zones in between. Although interventions such as indoor residual spraying (IRS), insecticide-treated nets (ITNs/LLINs), intermittent preventive treatment in pregnancy (IPTp), rapid diagnostic tests (RDTs), and artemisinin-based combination therapies (ACTs) have reduced the malaria burden, challenges persist in terms of funding, human resources, surveillance, and cross-border coordination. Achieving malaria elimination in the SADC region requires harmonised regional standards, strengthened surveillance, and improved access to quality treatment and policy prioritisation.
