The rapid increase in clinical cases of the new coronavirus disease, COVID-19, suggests high transmissibility. However, the estimates of the basic reproductive number reported in the literature vary widely. Considering this, we drew the function of contact-rate reduction required to control the transmission from both detectable and undetectable sources. Based on this, we offer a set of recommendations for symptomatic and asymptomatic populations during the current pandemic. Understanding the dynamics of transmission is essential to support government decisions and improve the community’s adherence to preventive measures. … Read More →

We have observed an increase in requests of chest computed tomography (CT) since the first records of cases in Brazil. It is crucial to highlight that the definite diagnosis of COVID-19 is made by RT-PCR, and a normal chest CT does not rule out diagnosis. However, currently, the RT-PCR result has taken longer than CT reports to be available, so CT has taken an important role in a comprehensive assessment of patients for demonstrating high sensitivity (although low specificity), to detect the most frequent pulmonary findings of the disease. … Read More →

Since there is no specific antiviral therapy for coronavirus infections to date, the announcement of partial and fragile data led to precipitated political manifestations by major government leaders and contributed to uncoordinated recommendations of the drug to severe patients. … Read More →

Based on an interdisciplinary approach, the article makes a social historical reading of the epidemics in the world and their impacts on human life, punctuating the differences with the so-called Covid-19. The proliferation of the virus has forced a radical change in the daily lives of populations on a global level, suggesting that it is possible to act collectively to create future worlds. The radical action of isolation against the virus has demonstrated relevant impacts with respect to the climate emergency, at a time when it reveals the impacts of denialism, the interests and limits of capitalism and the financial market in the epidemic crisis. … Read More →
