This review goal is to reflect on the challenges and prospects for water quality in the face of the pandemic caused by the new SARS-CoV-2 coronavirus (COVID-19). Based on the information available so far, the detection of SARS-CoV-2 RNA in wastewater has raised interest in using it as an early warning method, to detect the resurgence of infections and to report the risk associated with contracting SARS-CoV-2 in contact with untreated water or inadequately treated wastewater is discharged. The wastewater-based epidemiological approach can be used as an early indicator of infection within a specific population. On the other hand, it is necessary to collect information from the managers of drinking water supply companies and professionals who are related to water quality, to know SARS-CoV-2 data and information, and its influence on drinking water quality. The basic purpose of this review article is to try to provide a valuable and quick reference guide to COVID-19. Important topics were discussed, such as detection of SARS-CoV-2 in wastewater in various parts of the world; wastewater screening to monitor COVID-19; persistence of SARS-CoV-2 in aquatic systems; the presence of SARS-CoV-2 in drinking water; clean water as a mechanism to deal with the COVID-19 pandemic; chlorine as a disinfectant to eliminate SARSCoV-2 and damage to ecosystems by the use of chlorine. Currently does not exist extensive literature on the effectiveness of water and wastewater treatment processes that ensure the correct elimination of SARS-CoV-2. Excessive use of disinfectants such as chlorine is causing effects on the environment. This document lighlights the need for further research to establish the behavior of the SARS-CoV-2 virus in aquatic systems. This study presents an early overview of the observed and potential impacts of COVID-19 on the environment.

The term acne by Williams coined is a chronic disorder pilosebasea unit, but may occur at any stage of life is more common in puberty, and although it can be considered a benign process, is able to create psychological and severe in people who suffer for their ability to produce inflammatory lesions and scar sequels character, in this study social will take into account the most common acne is known that acne vulgaris or juvenile polymorph occur. As in its pathogenesis until now not known with certainty a definitive cause, rather several factors involved in its genesis such as alteration of keratinization in the excretory orifice of the sebaceous glands are indicated the action of microorganisms such as Propionibacterium acnes , staphylococcus epidermis and Pityrosporum ovale, increased sebaceous gland activity and other factors generic, emotional, food order. Despite that while these factors have been studied, the hormonal influence on sebaceous gland activity and especially androgens is under investigation, with those who have caused the most controversy. As there are conflicting studies have not demonstrated exactly markedly elevated androgens in acne patients, this study helps both the dermatologist and the general practitioner to deepen their knowledge on the pathogenesis and better prospects in polymorphous acne therapeutics youth
