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 Guide For Multicentre Trials in High-Burden Countries
Health facilities in the Region of the Americas frequently suffer the effects of health emergencies and disasters, which jeopardize their ability to provide services to the population. The STAR-H methodology helps staff responsible for health emergency and disaster risk management to identify and as...sess risks as part of strategic planning to improve facility preparedness. It is intended to help them develop, with a multi-hazard approach, a response framework with operating procedures to deal with hazards of any type, scale, or frequency; determine roles and responsibilities; facilitate the effective use of resources; undertake strategic planning exercises, and improve the preparedness of facilities to effectively respond to and recover from impacts. This methodology is designed for use in health facilities of any size and capacity, and makes it possible to generate historical reports and national or subnational risk profiles. This information can be used to develop an effective health emergency and disaster risk management program.

The strategy recommends that AU Member States should enhance, where feasible, existing COVID-19 surveillance to include:
Community-based surveillance to detect symptomatic cases early for treatment and to avert viral transmission;
Sentinel surveillance in high-risk populations to detect ...and track both presymptomatic and asymptomatic cases; and
Wastewater surveillance to monitor early environmental signs of virus transmission and identify communities where targeted interventions can be implemented to decrease transmission.

In March 2020, the World Health Organization (WHO) declared that the outbreak of COVID-19, the disease caused by a new coronavirus, constituted a pandemic, given the speed and scale of its transmission. The Region of the Americas is characterized by its rich multi-ethnic and multicultural heritage. ...Nonetheless, indigenous peoples, Afro-descendants, and other ethnic groups are often subject to discrimination and exclusion, resulting in health inequities. COVID-19 may have a greater impact on certain populations, such as indigenous peoples and Afro-descendants.

This handbook was designed primarily as a tool for district clinical specialist teams (DCSTs), and for the provincial specialists who will guide and support their work. This handbook will also be useful to managers of health facilities, heads of clinical units and nurses, doctors and allied health w...orkers at the coalface of clinical care. This handbook will be of interest to district managers and other members of the district management team who are dedicated to developing the capacity of the district health system to respond
effectively to the health needs of the population they serve. It will help them understand the role of the DCSTs and the type of
activities they need to engage in to improve the quality of care

The Infection Prevention and Control (IPC) Guidelines aim to support healthcare workers improve quality and safety health care. The Guidelines further aim to promote and facilitate the overall goal of IPC by providing evidence-based recommendations on the critical aspects of IPC, focusing on the fun...damental principles and priority action areas. All health service organizations should consider the risk of healthcare-associated infection(s) (HAI) and antimicrobial resistance (AMR) transmission to implement these recommendations. The IPC Guidelines also set national standards for the prevention and control of HAIs and to ensure compliance to the National Quality Standards.
