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.

Background: Community Health Workers (CHWs) have a positive impact on the provision of community-based
primary health care through screening, treatment, referral, psychosocial support, and accompaniment. With a
broad scope of work, CHW programs must balance the breadth and depth of tasks to mainta...in CHW motivation for
high-quality care delivery. Few studies have described the CHW perspective on intrinsic and extrinsic motivation to
enhance their programmatic activities.
Methods: We utilized an exploratory qualitative study design with CHWs employed in the household model in Neno
District, Malawi, to explore their perspectives on intrinsic and extrinsic motivators and dissatisfiers in their work. Data
was collected in 8 focus group discussions with 90 CHWs in October 2018 and March–April 2019 in seven purposively
selected catchment areas. All interviews were audiotaped, transcribed verbatim, coded, and analyzed using Dedoose.
Results: Themes of complex intrinsic and extrinsic factors were generated from the perspectives of the CHWs in
the focus group discussions. Study results indicate that enabling factors are primarily intrinsic factors such as positive
patient outcomes, community respect, and recognition by the formal health care system but can lead to the chal-
lenge of increased scope and workload. Extrinsic factors can provide challenges, including an increased scope and
workload from original expectations, lack of resources to utilize in their work, and rugged geography. However, a posi-
tive work environment through supportive relationships between CHWs and supervisors enables the CHWs.
Conclusion: This study demonstrated enabling factors and challenges for CHW performance from their perspec-
tive within the dual-factor theory. We can mitigate challenges through focused efforts to limit geographical distance,
manage workload, and strengthen CHW support to reinforce their recognition and trust. Such programmatic empha-
sis can focus on enhancing motivational factors found in this study to improve the CHWs’ experience in their role. The
engagement of CHWs, the communities, and the formal health care system is critical to improving the care provided
to the patients and communities, along with building supportive systems to recognize the work done by CHWs for
the primary health care systems.

Joint WHO/ILO guidelines on post-exposure prophylaxis (PEP) to prevent HIV infection.
The Coronavirus Disease 2019 (COVID-19) has had a continuous and robust impact on world health. The resulting COVID-19 pandemic has had a devastating physical, mental and fiscal impact on the millions of people living with noncommunicable diseases (NCDs), as they have a higher risk of severe illness... and death from COVID-19. COVID-19 has been associated with an
excess in all-cause and cardiovascular disease (CVD) mortality beyond that related to the infection itself and its immediate consequences. Studies in the
United Kingdom (UK) and United States of America (USA) have clearly shown increasing deaths from ischemic heart disease, stroke and hypertensive disease due to COVID-19. Overall, the impact has been greater in individuals with lower socioeconomic status, even in high income nations.

Guidelines approved by the WHO Guidelines -Review Committee; second edition
In fragile, conflict-affected and vulnerable settings, delivery of quality health services faces significant challenges, including disruption of a routine health service organization and delivery systems, increased health needs, complex and unpredictable resourcing issues, and vulnerability to multi...ple public health crises. Despite the difficulty of addressing quality in such settings, the necessity for action is acute, given the significant health needs of the populations in these environments and the increasing numbers of people for whom such settings are home.
This manual has been developed to provide a starting point for multi-actor efforts and actions to address quality of care in the most challenging settings. This includes practical approaches to action planning and implementation of a contextualised set of quality interventions.

Current and expected problems such as ageing, increased prevalence of chronic conditions and multi-morbidity, increased emphasison healthy lifestyle and prevention, and substitution for care from hospitals by care provided in the community encourage countries worldwide to develop new models of prima...ry care delivery. Owing to the fact that many tasks do not necessarily require the knowledge and skills of a doctor, interest in using nurses to expand the capacity of the primary care workforce is increasing. Substitution of nurses for doctors is one strategy used to improve access, efficiency, and quality of care. This is the first update of the Cochrane review published in 2005.
