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.

Evidence shows that FGM can cause several physical, mental and sexual health complications in girls and women, and in newborns. Health-care providers play an important role in supporting girls and women living with FGM, and improving their health and well-being. They are in a unique position to infl...uence and change the attitudes of their patients about FGM.
WHO is committed to scaling up the health-sector response to address FGM prevention and care. One aspect is to strengthen the quality of FGM prevention and care services by building the capacity of health-care providers. Several guidance materials have been produced to target health-care providers. These include FGM content for training curricula, clinical guidelines and a clinical handbook.
This training manual complements previous publications by building person-centred communication skills specifically for FGM prevention.

La evidencia disponible a nivel internacional sobre el uso de un segundo refuerzo muestra una mayor duración de la respuesta inmune y una disminución de la internación y la mortalidad por COVID 19 en la población de adultos mayores y huéspedes inmunocomprometidos. Por otra parte, el personal de... salud se beneficiaría considerando el mayor riesgo de exposición y la caída de la respuesta inmune con el tiempo. En base a lo señalado previamente se recomienda incorporar y
priorizar un segundo refuerzo al esquema de vacunación contra la COVID-19 del:
- Personal de salud independientemente de la edad
- Personas de 50 años o mayores
- Personas de 12 años o más con inmunocompromiso
A la vez, se progresará de manera escalonada y simultánea con la vacunación de segundo refuerzo del:
- Personal estratégico
- Personas de 18 a 49 años con factores de riesgo
Continuando en la estrategia de segundo refuerzo todas las personas a partir de los 18 años. Las personas gestantes con indicación de segundo refuerzo, se recomienda vacunas de plataforma de ARNm (Pfizer-BioNTech o Moderna)

As evidências atuais indicam que o vírus causador da doença COVID-19 é transmitido através de gotículas respiratórias ou por contato. A transmissão por contato ocorre quando as mãos contaminadas tocam a mucosa da boca, nariz ou olhos. O vírus também pode ser transferido de uma superfície... para outra através das mãos contaminadas, o que facilita a transmissão por contato indireto. Consequentemente, a higienização das mãos é extremamente importante para evitar a disseminação do vírus causador da doença COVID-19.

Emerging evidence and experience to inform risk management in a warming world
The evidence base for differentiated care for stable patients has grown in recent years. There has been less attention, however, to developing differentiated models of care for patients with advanced or unstable HIV disease. Current clinical guidelines and policies regarding optimal packages of care... for high-risk patients give few or no recommendations about how, by whom, or where they should be delivered for optimal impact.
