Paramount efforts worldwide are seeking to increase understanding of the basic virology of SARS-CoV-2, characterize the spectrum of complications associated with COVID-19, and develop vaccines that can protect from new and recurrent infections with SARS-CoV-2. While we continue learning about this new virus, it is clear that 1) the virus is spread via the respiratory route, primarily by droplets and contact with contaminated surfaces and fomites, as well as by aerosol formation during invasive respiratory procedures; 2) the airborne route is still controversial; and 3) that those infected can spread the virus without necessarily developing asymptomatic). With the number of SARS-CoV-2 infections increasing globally, the possibility of co-infections and/or co-morbidities is becoming more concerning. Co-infection with Human Immunodeficiency Virus (HIV) is one such example of polyparasitism of interest. This military-themed comparative review of SARS-CoV-2 and HIV details their virology and describes them figuratively as separate enemy armies. HIV, an old enemy dug into trenches in individuals already infected, and SARS-CoV-2 the new army, attempting to attack and capture territories, tissues and organs, in order to provide resources for their expansion. This analogy serves to aid in discussion of three main areas of focus and draw attention to how these viruses may cooperate to gain the upper hand in securing a host. Here we compare their target, the key receptors found on those tissues, viral lifecycles and tactics for immune response surveillance. The last focus is on the immune response to infection, addressing similarities in cytokines released. While the majority of HIV cases can be successfully managed with antiretroviral therapy nowadays, treatments for SARS-CoV-2 are still undergoing research given the novelty of this army.

Objective: To find the current prevalence of anxiety related with the COVID-19 pandemic in the pediatric population in our country and the factors that may be involved. Material and methods: Observational cross-sectional study, using an online survey. Age between seven and 17 years old, any gender, Mexican nationality, who had lived in Mexico for at least two weeks prior to filling out the questionnaire, voluntary participation, and fully answered surveys were included. Surveys that did not meet all the criteria were excluded. Descriptive statistics and analysis were carried out. χ 2 , bivariate logistic regression analysis, and odds ratio were used to assess the relationship between the outcome variables and the predictor factors. Results: A total of 970 surveys, 874 were analyzed. Significant relationship for higher risk of having anxiety with female gender, previous contact with a positive covid patient, having a psychological or psychiatric diagnosis, and lack of physical activity. Conclusions: Children and adolescents were affected in this COVID-19 quarantine in their psychosocial area, which increases our interest in their current situation and leads us to initiate an action plan to avoid complications in the future of our patients.

The current landscape represents an unprecedented challenge in managing surgical patients, decision-making and the use of resources such as protective equipment in the context of the COVID-19 pandemic. Therefore, the objective of this article is to provide guidelines for good conduct in the operating room, the use of personal protective equipment, suggestions for surgeries and the best approach in the context of this situation. The main objective of these recommendations is to mitigate the risk of contagion and to educate medical-surgical health personnel in how to deal with this pandemic. Key words: COVID-19; coronavirus: protective equipment; surgery; operating room; training; emergency
