Há três objetivos preliminares desse estudo de transmissão doméstica: 1. Para compreender melhor a extensão da transmissão doméstica estimando a taxa de infecção secundária1 para contatos domésticos em uma maneira individual, e fatores associados com qualquer variação no risco secundár...io da infecção. 2. Para caraterizar casos secundários incluindo a escala da apresentação clínica, fatores de risco para a infecção, a extensão e a fração de infecções assintomáticas. 3. Para caraterizar a resposta sorológica que segue a infecção confirmada pelo 2019-nCoV (altamente incentivado, mas opcional dependendo da capacidade e dos recursos do laboratório).

Universal health coverage (UHC) depends on a strong primary health-care
system. To be successful, primary health care must be expanded at community and household levels as much of the world’s population still lacks access to health facilities for basic... services. Abundant evidence shows that community-based interventions are effective for improving health-care utilization and outcomes when integrated with facility-based services. Community involvement is the cornerstone of local, equitable and integrated primary health care.

n October 2019, WHO convened the first meeting of the Buruli ulcer laboratory network (BU-LABNET) in Yaoundé, Cameroon, bringing together 11 laboratories from nine countries at the Pasteur Centre of Cameroon (CPC), the network’s Coordinating Centre. The network was formally established at th...is meeting (1) and its members were those present. The objective of BU LABNET is to improve diagnosis of Buruli ulcer based on polymerase chain reaction (PCR) using standardized testing protocols, involving external quality assurance programmes and sharing knowledge among member laboratories.

La mise à jour 2017 du rapport du Programme commun de suivi de l'approvisionnement en eau et de l'assainissement présente les indicateurs et les estimations de base pour les objectifs de développement durable liés à l'approvisionnement en eau, à l'assainissement et à l'hygiène. Le rapport é...nonce les indicateurs des services d'approvisionnement en eau potable et d'assainissement "gérés en toute sécurité", ce qui va au-delà de l'utilisation d'installations améliorées et prend en compte de la qualité des services fournis. Pour la première fois, des estimations relatives à l'hygiène pour 70 pays sont incluses dans le rapport.

Global growth is projected to slow significantly amid high inflation, tight monetary policy, and more restrictive credit conditions. The possibility of more widespread bank turmoil and tighter monetary policy could result in even weaker global growth and lead to financial dislocations in the most vu...lnerable emerging market and developing economies (EMDEs). Comprehensive policy action is needed to foster macroeconomic and financial stability. Among many EMDEs, and especially in low-income countries, bolstering fiscal sustainability will require generating higher revenues, making spending more efficient, and improving debt management practices. Continued international cooperation is also necessary to tackle climate change, support populations affected by crises and hunger, and provide debt relief where needed.

From Participation to Partnerships (September 2020)
Despite the COVID-19 challenges, children around the world have found meaningful ways to support and protect their peers, families, and communities. Children are on the frontlines of innovative responses and are working closely with their adult al...lies. The leadership demonstrated through these child-adult partnerships is the underlying inspiration for this guide.

Le Plan Stratégique Multisectoriel d’Élimination du Choléra en République Démocratique du Congo (2013-2017) vise à réduire l’incidence du choléra à moins d’un cas pour 100 000 habitants. Ce plan repose sur une approche multisectorielle, combinant santé, eau, hygiène et assainissemen...t pour enrayer la transmission du choléra.
Il identifie trois types de zones : zones sources (A), zones épidémiques (B) et zones de diffusion (C), chacune nécessitant des interventions adaptées. Les stratégies incluent l’amélioration des infrastructures d’eau potable et d’assainissement, la surveillance épidémiologique, la prévention, la prise en charge médicale et la coordination des actions.
Malgré des progrès dans certaines régions, la mise en œuvre du plan a rencontré des défis, notamment en raison du manque de financements et de la persistance de foyers endémiques dans l'Est du pays. Une coordination nationale et internationale est essentielle pour mobiliser les ressources et atteindre l'objectif d'élimination du choléra en RDC.

Technical specifications for selection of essential in vitro diagnostic tests for SARS-COV-2, 14 June 2021
The conditionality of this recommendation is largely driven by the current higher unit cost of pyrethroid-PBO ITNs compared
to pyrethroid-only LLINs and therefore the uncertainty of their cost-effectiveness. Furthermore, as PBO is less wash-resistant
than pyrethroids, its bioavailability declines ...faster over the three-year estimated life of an ITN; therefore, the added impact of
pyrethroid-PBO ITNs over that of pyrethroid-only LLINs may decline over time. The evidence comes from two sites in
eastern Africa with pyrethroid resistance and not from other geographies where transmission levels and vector characteristics
may vary. PBO acts by inhibiting certain metabolic enzymes, primarily oxidases, and so are likely to provide greater protection
than pyrethroid-only LLINs where mosquitoes display mono-oxygenase-based insecticide resistance mechanisms.

Chagas disease, also known as American trypanosomiasis, is a neglected tropical disease transmitted by triatomine insects, first identified in 1909. Chagas disease affects approximately 6–7 million peop...le globally and is highly prevalent in Latin America where most cases are reported. However, there is increasing evidence that Chagas disease is now an important public health issue outside the “classical” endemic countries due to population migration. Our understanding of Chagas disease, including its pathologies and factors relating to progression, remains to date limited, and is also challenged by lack of diagnosis and highly effective treatment. This systematic review aims to describe studies with Chagas patients receiving antiparasitic treatment. Databases were searched for relevant studies published after 1997, and the results of these searches were screened.

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.

Biosafety involves the implementation of containment principles, technologies and practices to prevent unintentional exposure to biological agents. Biosecurity involves the protection, control and accountability of biological materials and information related to these materials and dualuse research,... to prevent their unauthorized access, loss, theft, misuse, diversion or intentional release.
