In the light of the transmissibility of coronaviruses, and the global experience with MERS-CoV (ongoing) and SARS in 2003 which were also caused by coronaviruses, South African authorities have compiled this guideline document to support surveillance, case finding, diagnosis, management and public h...ealth responses to cases under investigation.
*Please note*
The interim guidelines are based on what is currently known about the Coronavirus Disease 2019 (COVID-19). The National Department of Health (NDOH) and National Institute for Communicable Diseases will update these interim guidelines as needed and as additional information becomes available.

Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

It is Zika virus (ZIKV) that most often causes these neurological effects it appears to be the only arbovirus than can cause congenital malformations such as microcephaly. In any case, more scientific tests are needed to establish the causal relationship between the virus and this malformation (7-10...).
This document is a practical tool designed to help health workers improve clinical diagnosis and provide timely care for patients infected
with the dengue, chikungunya, or Zika virus. It is intended mainly for
health workers in primary care facilities where laboratory diagnosis of
arboviruses is not always available. However, this guide may also be
very useful in hospitals that provide second- and third-level care, as it
describes the clinical manifestations of each of the three most important
arboviral diseases currently found in the Region, the elements for
differential diagnosis, and their clinical behavior.

The article is a scoping review that explores the challenges in diagnosing asthma in children in three sub-Saharan African countries: Nigeria, South Africa, and Uganda. It identifies key barriers, such as a lack of community awareness, inadequate healthcare access, limited diagnostic tools like spir...ometry, and insufficient knowledge among healthcare workers. The review also highlights the stigma associated with asthma and the absence of relevant diagnostic guidelines. Solutions proposed include community education, development and adherence to diagnostic guidelines, and strengthening healthcare systems. The study aims to inform policymakers and healthcare providers to improve asthma diagnosis and care for children in these regions.

Tuberculosis (TB) is the deadliest infectious disease in most low- and middle-income countries, claiming more than 4,000 lives each day. The unprecedented COVID-19 pandemic has seriously impacted people with pre-existing health conditions. People with TB are usually more vulnerable to other infectio...ns, including the novel coronavirus, due to pre-existing lung damage. They are also at higher risk of developing complications from COVID-19.

The cardiovascular disease continuum begins with risk factors such as diabetes mellitus (DM), progresses to vasculopathy and myocardial dysfunction, and finally ends with cardiovascular death. Diabetes is associated with a 2- to 4-fold increased risk for heart failure (HF). Moreover, HF patients wit...h DM have a worse prognosis than those without DM. Diabetes can cause myocardial ischemia via micro- and macrovasculopathy and can directly exert deleterious effects on the myocardium. Hyperglycemia, hyperinsulinemia, and insulin resistance can cause alterations in vascular homeostasis. Then, reduced nitric oxide and increased reactive oxygen species levels favor inflammation leading to atherothrombotic progression and myocardial dysfunction. The classification, diagnosis, and treatment of HF for a patient with and without DM remain the same. Until now, drugs targeting neurohumoral and metabolic pathways improved mortality and morbidity in HF with reduced ejection fraction (HFrEF). Therefore, all HFrEF patients should receive guideline-directed medical therapy. By contrast, drugs modulating neurohumoral activity did not improve survival in HF with preserved ejection fraction (HFpEF) patients. Trials investigating whether sodium-glucose cotransporter-2 inhibitors are effective in HFpEF are on-going. This review will summarize the epidemiology, pathophysiology, and treatment of HF in diabetes.

Esta guía está enfocada en emitir recomendaciones para el diagnóstico y el tratamiento de la enfermedad de Chagas, como infección por Trypanosoma cruzi, agente protozoario de una parasitosis sistémica. Metodología: La presente guía de práctica clínica fue confeccionada siguiendo los método...s de elaboración de guías de la OMS (5). De forma general, se conformó un grupo desarrollador multidisciplinario compuesto por expertos temáticos, epidemiólogos, metodólogos y usuarios. Dado que no se identificaron guías susceptibles de ser adaptadas, la guía se desarrolló de novo.

Desde el 2010, los Estados miembros de la Organización Panamericana
de la Salud (OPS) han asumido el compromiso de impulsar la eliminación de la transmisión materno infantil (ETMI) de la infección por el VIH y la sífilis. Estos compromisos se renovaron y ampliaron en el año 2016 mediante la... aprobación del “Plan de acción para la prevención y el control de la infección por el VIH y las infecciones de transmisión sexual 2016-2021”. Este Plan amplía la iniciativa de ETMI (la renombra "ETMI-Plus") para incluir la eliminación de otras enfermedades transmisibles prevenibles en la Región, como la hepatitis B y la enfermedad de Chagas.

Evidence-based guidelines are one of the most useful tools for improving public health and clinical practice. Their purpose is to formulate interventions based on strong evidence of efficacy, avoid unnecessary risks, use resources efficiently, reduce clinical variability and, in essence, improve hea...lth and ensure quality care, which is the purpose of health systems and services. These guidelines were developed following the GRADE methodology, with the support of a panel of clinical experts from different countries, all convened by the Pan American Health Organization. By responding to twelve key questions about the clinical diagnosis and treatment of dengue, chikungunya, and Zika, evidence-based recommendations were formulated for pediatric, youth, adult, older adult, and pregnant patients who are exposed to these diseases or have a suspected or confirmed diagnosis of infection. The purpose of the guidelines is to prevent progression to severe forms of these diseases and the fatal events they may cause. The recommendations are intended for health professionals, including general, resident, and specialist physicians, nursing professionals, and medical and nursing students, who participate in caring for patients with suspected dengue, chikungunya, or Zika. They are also intended for health unit managers and the executive teams of national arboviral disease prevention and control programs, who are responsible for facilitating the process of implementing these guidelines.

The NICE guideline "Hypertension in Adults: Diagnosis and Management" outlines recommendations for diagnosing and managing hypertension in adults over 18, including those with type 2 diabetes. It emphasizes accurate blood pressure measurement, recommending ambulatory or home monitoring to confirm di...agnosis. Cardiovascular risk and target organ damage should be assessed, considering age, lifestyle, and other conditions. Initial treatment focuses on lifestyle changes such as diet, exercise, and smoking cessation, with medication advised for stage 1 hypertension at high cardiovascular risk or stage 2 hypertension. Regular monitoring and treatment adjustments are recommended to maintain target blood pressure levels, with specific guidance for people over 80 and those with additional conditions like diabetes or kidney disease. The guideline aims to reduce risks of heart attack, stroke, and other complications, supporting evidence-based treatment decisions in clinical practice.
