Before the severe acute respiratory syndrome outbreak in 2003, coronaviruses (CoVs) were not considered to be highly pathogenic to humans. However, it was this epidemic that highlighted this group of viruses and included them among the causative agents of emerging epidemic diseases. In addition, in 2012, another new CoV responsible for the Middle East respiratory syndrome was identified. ⋯ This new CoV, called 2019-nCoV, was originated in the city of Wuhan, China, and has been linked to severe respiratory infections in humans. Thanks to the collaboration of experts worldwide, more information about this virus and its infection is reported each day, which allows modifying the recommendations for its prevention and treatment, without forgetting that the ultimate goal is to control this epidemic. In this review, the important aspects of this new coronavirus, 2019-nCoV, and its disease, COVID-19, have been summarized with the information available up to February 2020.

ReviewSARS-CoV-2: previous coronaviruses, immune response, and development of vaccines.
Since the emergence of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in China at the end of 2019, when its characteristics were practically unknown, one aspect was evident: its high contagion rate. This high infection rate resulted in the spread of the virus in China, Europe, and, eventually, the rest of the world, including Mexico. At present, around 9 million people are infected, and around 470,000 have died worldwide. ⋯ This opinion article will present the evidence of the induction of immune response in some of the viruses of the coronavirus family before COVID-19, such as SARS-CoV and MERS-CoV (Middle East respiratory syndrome coronavirus). The information collected about the induction of an immune response by SARS-CoV-2 will be presented, as well as a description of the vaccine candidates reported to date in the various ongoing clinical trials. Finally, an opinion based on the evidence presented will be issued on the potential success of developing vaccine prototypes.

ReviewConsiderations on the use of antihypertensive blockers of the renin-angiotensin system in adults and children in the face of the COVID-19 pandemic.
As severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected patients with hypertension and other cardiovascular comorbidities develop more severe coronavirus disease (COVID)-19 and are at high risk of death, a controversy arose about the use of antihypertensives as angiotensin-converting enzyme inhibitors (ACEis) and angiotensin II receptor blockers (ARBs). Such drugs might increase the expression of the fundamental receptor of this new infectious agent: the angiotensin-converting enzyme 2 (ACE2). Preclinical observations indicate that the increase of ACE2 expression or the activity by ACEis and ARBs leads to a greater transformation of angiotensin (Ang)-II to Ang-(1-7), which is associated with positive effects on cardiovascular and pulmonary pathophysiology. ⋯ It has not been possible to confirm whether users of ACEis or ARBs are more infected by the new coronavirus, due to methodological issues in studies with patients infected with SARS-CoV-2. However, the use of such antihypertensive treatments in both children and adults might reduce the virulence of infection. Therefore, changes in the antihypertensive therapy of patients at risk of contracting COVID-19 are not recommended.

Measles is an exanthematous disease caused by a virus of the Morbillivirus genus. On February 23, 2020, the exanthema began in the first confirmed case of measles this year. At the same time, on February 28, 2020, the first case of the new coronavirus disease (COVID-19) was confirmed. ⋯ Hence, a campaign of social distancing started as part of the strategies to control the spread of the infection. The potential threat is that as social confinement measures are relaxed and mobility is initiated, both viruses could continue to spread. It is expected that due to the time that has passed since the last reported measles case, control of this disease will be achieved.

Knowledge of nursing staff at a pediatric referral hospital regarding the assessment and management of pain in children.
Pain is a frequent reason for consultation. Poor vocational training is referred to as a critical component for proper treatment. The objective of this study was to describe the knowledge and practices of the nursing staff of the Pediatric Hospital, Pereira Rossell Hospital Center, regarding the assessment and approach of pain in children. ⋯ The surveys demonstrated acceptable knowledge about pain assessment and management. However, aspects to improve in the knowledge of scales of evaluation in special populations, lack of familiarity with the use of opioids and conceptions of subjective evaluation of pain were objectified.
