After SARS-CoV-2, will H5N6 and other influenza viruses follow the pandemic path?

While the world is focused on attending, controlling, and mitigating the current pandemic of COVID-19, caused by the SARS-CoV-2, other viral threats are possibly emerging and reemerging especially in Asia, posing a risk for the spread in that region and beyond. A predictable threat is the avian influenza virus, especially H5N6, which has recently led to significant outbreaks in China and the Philippines, deserving more attention and control. In the current review, we assess the history of this highly pathogenic reemerging virus, as well as the contemporary implications of poultry outbreaks occurring in some Asian countries. We also look at outbreaks due to other strains not only in Asia but also across Europe and Africa, according to recent reports from the World Organization of Animal Health (OIE).

Bats in ecosystems and their Wide spectrum of viral infectious potential threats: SARS-CoV-2 and other emerging viruses.

Bats have populated earth for approximately 52 million years, serving as natural reservoirs for a variety of viruses through the course of evolution. Transmission of highly pathogenic viruses from bats has been suspected or linked to a spectrum of potential emerging infectious diseases in humans and animals worldwide. Examples of such viruses include Marburg, Ebolavirus, Nipah, Hendra, Influenza A, Dengue, Equine Encephalitis viruses, Lyssaviruses, Madariaga and Coronaviruses, involving the now pandemic Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Herein, we provide a narrative review focused in selected emerging viral infectious diseases that have been reported from bats.

Mechanical ventilation in SARS-CoV-2 patients: state of art

COVID-19-associated infection leads to a pathology of yet unknown clinical behavior, confronting the clinician with various challenges. An extensive search was conducted based on review articles on SARS-CoV-2 infection and studies including mechanical ventilation management strategies in order to complete this narrative review. Evidenced-based treatment for SARS-CoV2 infection is still in the works. We have some tools from our knowledge from past experiences indicating that a step-wise management approach should be used, without neglecting other joint therapeutic measures for improved clinical outcomes of a condition with a high mortality. The current recommendations indicate that patients with severe acute respiratory failure due to SARS-CoV-2 should be managed with protective mechanical ventilation measures. No strong evidence is yet available on the individualization of mechanical ventilation therapy according to phenotypes.

Para esta revisión narrativa se llevó a cabo una extensa búsqueda basada en artículos de revisión sobre la infección por SARS-CoV-2 y estudios que incluían estrategias de manejo con ventilación mecánica. El tratamiento basado en evidencia para la infección por SARS-CoV2 todavía está en desarrollo. Tenemos algunas herramientas basadas en nuestros conocimientos de experiencias en el pasado que indican que se debe usar un abordaje escalonado, sin descuidar otras medidas terapéuticas conjuntas para mejorar los desenlaces clínicos de una condición con una elevada mortalidad. Las actuales recomendaciones indican que los pacientes con falla respiratoria aguda por SARS-CoV-2 deben manejarse con medidas de protección con ventilación mecánica. Aún no tenemos una sólida evidencia sobre la individualización del tratamiento con ventilación mecánica, de acuerdo a los distintos fenotipos.
