- Efficacy of disinfecting inanimate surfaces against coronavirus: a systematic reviewPublication . Basso, Isabela; Schroder, Angela Graciela Deliga; Sampaio Santos, Rosane; Ravazzi, Gloria; Gonçalves, Flávio Magno; Stechman-Neto, José; Zeigelboim, Bianca Simone; Guariza Filho, Odilon; Araujo, CristianoHuman coronaviruses tend to persist on dry surfaces for 2 to 9 days, necessitating infection control and prevention protocols using biocidal agents. This systematic review aimed to answer the following focused question: What is the effectiveness of disinfectants on inanimate surfaces against the coronavirus? The acronym “PICOS” was used to represent the eligibility of studies: P = population (inanimate surfaces contaminated with coronavirus); I = intervention (disinfectants); C = comparison (studies with any type of control or studies that used a control group); O = outcomes (coronavirus inactivation on different types of inanimate surfaces); and S = study design (in vitro studies). The seven databases used were PubMed/Medline, EMBASE, Latin American and Caribbean Literature on Health Sciences (LILACS), Web of Science, Scopus, LIVIVO, and Cochrane Library. The gray literature was also used as an information source through Google Scholar, ProQuest, and Open Gray. The search resulted in 6639 references, and 21 articles were used in the qualitative analysis. The results showed that all studied biocidal solutions provided some degree of decontamination and inactivation of the coronavirus, depending on the concentration of the disinfectant solution, the time of exposure of the product to the pathogen and the type of surface.
- Coronavirus survival time on inanimate surfaces: a systematic reviewPublication . Schroder, Angela Graciela Deliga; Stechman-Neto, José; Basso, Isabela; Gonçalves, Flávio Magno; Cavalcante-Leão, Bianca; Ravazzi, Gloria; Zeigelboim, Bianca Simone; Povh, Bruna; Guariza Filho, Odilon; Sampaio Santos, Rosane; Araujo, CristianoThis systematic review aimed to study the survival time of the virus from the coronavidae family on various materials and surfaces, thus enabling the adoption of preventive measures mainly in public environments. The electronic databases selected as a source of information were PubMed/Medline, Excerpta Medica database (EMBASE), Latin American and Caribbean Literature in Health Sciences (LILACS), Web of Science, Scopus, and LIVIVO; grey literature (Google Scholar, ProQuest, and OpenGrey) was also examined. The last electronic search of the six databases retrieved 4287 references. After removing the duplicate references, the titles and abstracts (phase 1) were read, and 37 articles were selected for complete reading (phase 2), which resulted in 13 included studies. All the studies evaluated coronavirus survival on the following surfaces and objects: stainless steel, glass, plastic, wood, metal, cloth, paper, cotton, latex, polystyrene petri dish, aluminium, copper, cardboard, Teflon, polyvinyl chloride (PVC), silicone rubber and disposable fabric. On surfaces such as glass, plastic, and steel, the virus has greater stability than it does on copper, fabric, paper, and cardboard. The conditions of temperature, relative humidity, absorption power, and texture were also considered important factors in the survival of the virus.
