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.

Clinical care for severe acute respiratory infection: toolkit: COVID-19 adaptation
The larval stage of the parasite Taenia solium can encyst in the central nervous system causing neurocysticercosis, which is the main cause of acquired epilepsy in the countries in which the parasite is endemic. Endemic areas are those with the presence (or likely presence) of the full life cycle of... Taenia solium. The parasite is most prevalent in poor and vulnerable communities in which pigs roam free, open defecation is practiced, basic sanitation is deficient, and health education is absent or limited. Several tools are available for the control of Taenia solium. Preventive chemotherapy for Taenia solium taeniasis, which is directed at the adult tapeworm, is one of them. Other tools focus on pig management, pig vaccination and treatment, sanitation and hygiene, and community education. Three potential drugs—niclosamide, praziquantel, and albendazole—have been considered for use for preventive chemotherapy in Taenia solium taeniasis control programs through mass drug administration or targeted chemotherapy. In this Guideline, we provide recommendations for preventive chemotherapy in Taenia solium-endemic areas using niclosamide, praziquantel, or albendazole, including at which dose and in which population groups.

ECDC Technical Report
In line with ECDC’s recommendations provided in the ’Risk Assessment of HTLV-1/2 transmission by tissue/cell transplantation’ dated 14 March 2012, this Directive replaces the term ‘incidence’ with ‘prevalence’ in the description of endemic areas of HTLV-1/2 i...nfection. According to the new requirements ‘HTLV-1 antibody testing must be performed for donors living in, or originating from high-prevalence areas or with sexual partners originating from those areas or where the donor’s parents originate from those areas’ and this applies to both donors of non-reproductive tissues and cells and reproductive cells.
ECDC contracted experts from the Institut Pasteur in Paris to systematically review the published evidence on the distribution of HTLV-1 infection prevalence throughout the world and to identify high-prevalence countries and areas.

The far-reaching impacts of the COVID-19 pandemic underscore the critical need for evidence-informed, transparent and inclusive decision-making. Policy-makers have grappled with complex choices amidst uncertainty. They have constantly reassessed response measures while navigating their economic impl...ications and unintended consequences on societal well-being. Effective communication of the basis for these decisions has also posed a challenge, requiring transparency and public trust.

The manual is written for clinicians working at the district hospital (first-level referral care) who diagnose and manage sick adolescents and adults in resource constrained settings. It aims to support clinical reasoning, and to provide an effective clinical approach and protocols for the managemen...t of common and serious or potentially life-threatening conditions at district hospitals. The target audience thus includes doctors, clinical officers, health officers, and senior nurse practitioners. It has been designed to be applicable in both high and low HIV prevalence settings.
Volume 2 provides a symptom-based approach to clinical care for acute and subacute conditions (including mental health). It provides short summaries of the management of diseases that affect multiple systems of the body, focusing on communicable diseases. It also includes the chronic or long-term management of HIV, TB, alcohol, and substance use disorders.

Policy Brief. Good practice statement: When planning and implementing a response for HIV, viral hepatitis and sexually transmitted diseases (STIs), policy-makers and providers should be aware that

hepatitis and STIs’ incidence nor on risk behaviour such as condom use and needle/syringe
sharing. Counselling and information sharing, not aimed at changing behaviours, can be a key
component of engagement with key populations and, when provided, it should be in a nonjudgemental manner, alongside other prevention interventions and with involvement of peers

Behaviour-change interventions have been consistently considered an essential part of comprehensive HIV, STI and unintended pregnancy prevention. In 2015, the World Health Organization reviewed and assessed existing evidence ...on brief behavioural interventions, leading to the publication of Brief sexuality-related communication: recommendations for a public health approach. This guideline recommends the use of brief behaviour intervention and communication programmes to promote sexual health and to prevent HIV, STIs, and unintended pregnancies in primary health services, particularly sexual and reproductive health services.
