COVID-19 in Brazil: advantages of a socialized unified health system and preparation to contain cases.
The outbreak of new coronavirus disease 2019 (COVID-19) reported for the first time in Wuhan, China in late December 2019 have rapidly spread to other countries and it was declared on January 30, 2020 as a public health emergency of international concern (PHEIC) by the World Health Organization. Before the first COVID-19 cases were reported in Brazil, several measures have been implemented including the adjustment of legal framework to carry out isolation and quarantine. ⋯ Rapid and robust preparedness actions have been undertaken in Brazil while first cases have not yet been identified in Latin-American. The outcome of this early preparation should be analyzed in future studies.

The COVID-19 pandemic has led to measures of social isolation, labor restrictions, a strong information campaign and the suspension of scheduled medical activities. The aim of this study was to describe the impact of these measures on the number of hospitalizations in Cardiovascular Intensive Care Units, with the hypothesis that the social behavior generated by this emergency promotes a decreased demand for medical care, even when severe cardiovascular disease is involved. We compared the number of admissions in March-April 2010-2019 versus March-April 2020, based on a prospective study including six institutions (three public and three private) that use Epi-Cardio® as a multicenter registry of cardiovascular care unit discharge. ⋯ Although with low prevalence, hypertensive crisis increased in 89%. The abrupt decrease observed in the number of admissions due to critical pathologies may be considered an "adverse effect" related to the measures adopted, with potentially severe consequences. This trend could be reversed by improving public communication and policy adjustment.

Recent emergence of SARS-CoV-2 in human communities as the first major zoonotic pandemics of the new millennium following the emergence of SARS-CoV and MERS-CoV has increased our awareness about the future threat of viral zoonosis. Although, several studies have been conducted for better understanding of these viruses` evolution, and designing the effective anti-viral drugs and vaccines, the impact of human beings on occurrence of zoonotic diseases has been less considered and discussed. Improvement in global health resulted in human population growth, increasing demand for animal proteins, more exposures to wildlife, zoonotic and degradation of environment, which have facilitated interspecies transmissions. ⋯ It seems that intensified revision of human lifestyle is the best strategy to prevent the potential devastating future zoonotic pandemics. Herein, the characteristics of SARS-CoV, MERS-CoV, SARS-CoV-2, their transmission routs, their pathogenicity, the therapeutic and prevention approaches including of attempts for designing of effective prophylactic vaccines, anti-viral drugs, and the animal models that have been used for these studies have been reviewed (Ref. 134). Keywords: SARS-CoV-2, COVID-19, pandemic, zoonosis, SARS, MERS.

The epidemic of Coronavirus disease 2019 (COVID-19) in China caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has become a global concern and subsequently labeled a pandemic by the World Health Organization on March 11th. As the world mobilizes to contain the COVID-19, scientists and public health experts are increasingly alarmed about the potentially catastrophic effects of an outbreak in Africa. ⋯ However, we speculate that the fear associated with COVID-19 may also lead to some of the long-standing messages about simple measures to reduce the spread, such as hand washing, finally becoming absorbed and more universally adopted by health workers and the public. Is it possible that regardless of the terrible threat posed by SARS-CoV-2, the increased adoption of these health protection measures may result in a reduction in the spread of other infectious diseases?
