ABSTRACT
Background: The disease sprouts by coronavirus 2019 (COVID-19) is an important event in the health and well-being of people around the world. The worldwide public interest in this new topic reflects to a large extent the attention of people to COVID-19 and their willingness to take precautionary measures. Objective: Examine the worldwide public awareness of COVID-19 using Google Trends. Methods: Using Google Trends, we retrieved data from public consultations for the terms of [COVID-19 coronavirus + quarantine + face masks + handwash + chloroquine + azithromycin] between the 1st of December 2019 until the 25th of April 2020 in four countries (Peru, Ecuador, Chile and Brazil). The dynamic analysis of series shows the general exchange rate trend of the relative volume (RSV) for the theme in COVID-19. The correlation between the daily search volumes on the topic related to COVID-19 and the daily number of people infected with SARS-CoV-2 was analyzed. Results: Our studies have observed that the general trend of RSV searches with respect to topics related to COVID-19 increased during the initial period of observation time and reached the first point of the first week of March 2020 in the majority of countries. A slightly positive correlation was observed between the daily RSV on the topic related to COVID-19 and the daily number of people infected with SARS-CoV-2 in the majority of countries. Conclusions: The current study reminds us that governments should strengthen COVID-19 publicity at national level, strengthen public awareness and awareness of COVID-19, inform the public about the importance of protecting themselves with sufficient precautionary measures and finally to control the spread of COVID19 worldwide. © 2021, Editorial Ciencias Medicas.

ABSTRACT
The new coronavirus 2019 disease (COVID-19) is caused by the virus called SARS-CoV-2, however, in free-range chicken's coronaviruses cause Avian Infectious Bronchitis. Currently, it has been possible to analyze the genomic sequence of the SARS-CoV-2 virus, which indicates that it emerged from an animal reservoir, it has even been considered that a virus isolated from a bat, identical to SARS-CoV, is the parent of the new coronavirus. In other studies, it has been shown that the glycoprotein of the viral spicule has a high degree of relationship between viruses that infect mammals and birds, which is the one that allows contact with the host. Whereas in the case of IBV, when inhaled, the virus will bind to sialic acid-containing gly-coprotein receptors in hair epithelial cells of respiratory tissue, then viral replication will result in loss of ciliary function, mucus clearance, necrosis, and peeling, causing shortness of breath and suffocation. IBV affects the trachea, kidneys, and reproductive tract of many birds. In chickens, viremic IBV causes lesions in the magnum and the uterus. This review elucidates some key points in the differences between the novel coronavirus and the infectious bronchitis virus. SARS-CoV-2 is highly unlikely to infect or cause disease in poultry.
ABSTRACT
Objetive. To describe the perceptions and knowledge about COVID-19. Material and Method: Cross-sectional study, an online survey of 314 participants was conducted, the questionnaire consists of 9 multiplechoice questions, the data were analyzed using descriptive statistics. Results: The average age of the respondents was 26.9 years, the sample comprised more women 161 (51.3%) than men and almost 89% of the respondents belonged to undergraduate, the place of origin of the Covid-19 was well known 94.30%, for half of the respondents 159 (50.6%) it is not a zoonotic disease, concerning the COVID-19 prevention measures the majority of the respondents consider that handwashing is an of the main prevention measures. Conclusion: CAP studies are important for a better understanding of the perception and knowledge of COVID-19. The study revealed that respondents generally have some general knowledge about SARS-CoV-2.
ABSTRACT
Introduction: Genomic analysis of samples from documented COVID-19 cases can be used successfully to help track sources of Sars-Cov-2 infection, which can be quarantined to prevent the recurrent spread of the disease around the world. Objectives: To describe the SARS-CoV-2 sequences isolated from Peruvian patients. Methods: All genomes published up to March 2021, uploaded in the GISAID and Nextstrain repository, were selected. All data is on the web in a public way;In addition, the information was filtered by continent, country, region, clade, lineage, and sex from March 2020 to February 2021. Results: It was evidenced that the region with the most isolated genomes was Lima, the most frequent clade is GR, the viral lineage B.1.1 is the most frequent and persistent in time and most of the genomes were isolated from people of the female sex. Conclusions: The clade GR is common to all South American countries and the European and Asian continents, followed by clades G and GH with greater frequency;on the other hand, the most persistent viral lineage in Peru is B.1.1, this being not common with other countries.
