The Reopening of Schools and Adoption of Universal Wearing of Face Masks in Anticipation of Sustained Transmission or the Second Wave of COVID-19 with the Influenza Virus

The Covid-19 pandemic has swept rapidly from Wuhan, China to the entire globe in less than six months, infecting over 7 million people and claiming the lives of over 500,000. In the United States, greater than 2 million individuals have become infected and over 110,000 people killed. With no evidenc…

Biomedical Infophysical Models of Filtering Ghost Airflows by Wearing Masks and Maintaining Social Distancing to Prevent COVID-19 and Reopen All Systems after Shutdowns (Lockdowns)

The COVID-19 pandemic has killed more than 400 thousand and infected more than 7 million people in the whole world as of 06/10/2020. Many open systems, such as educations, transportations, entertainments, sports or foods, have been completely or partially locked down in many regions of the world to…

New Approaches in the Treatment of Covid-19 Virus

By increase the incidence of infection of coronavirus disease 2019 (COVID-19), diagnostic factors for early identification of high-risk individuals are important. On the other hand, more infections are in older patient, comorbidities, and male patients. Identification of components that related to s…

Brazil and COVID-19: Challenges of Remote Education in Basic Education

A commentary on remote education challenges during COVID‑19 in Brazil. It covers equity, infrastructure, teacher training, and student engagement, proposing pragmatic steps to support learning continuity.

How Valid are the Reported Cases of People Infected with Covid-19 in the World?

The goal of this paper is to analyze the registered cases of people who have been infected with Covid-19 registered from throughout the world, using a digital forensic analysis technique that is based on Benford's Law. Twenty-three countries were randomly chosen for this analysis: China, India, Germ…

The Novel Coronavirus 2019 (COVID-19): A Narrative Review

One of the key steps in determining how to prevent the viral disease is to identify the virus. The virus lives in different ways and in different environments. It lives in the air, in the sea, on plants, animals and objects and humans. Some people put humans on the path of developing zoonotic diseas…

COVID-19 and New Forms of Acute Pneumonia. It's Time for A Brainstorming Session

This perspective calls for cross‑disciplinary brainstorming on novel COVID‑19 pneumonia phenotypes. It discusses hypotheses on immune dysregulation, microvascular injury, and tailored respiratory strategies.

Adaptive Artificial Passive Immunity as a Suggested Strategy for Treatment of COVID-19 Critical Cases

Currently, the emergence of a novel human corona virus, SARS-CoV-2, has become a global health concern causing severe respiratory tract infections in humans. Human-to-human transmissions have been described with incubation times between 2-14 days, facilitating its spread via droplets, contaminated h…
