ABSTRACT
ABSTRACT BACKGROUND: Brazil is facing increasing cycles of numbers of infected people and deaths resulting from coronavirus disease 2019 (COVID-19). This situation involves a series of factors, including the behavior of the population, that can be decisive for controlling the disease. OBJECTIVE: To determine the knowledge, attitudes and practices of the Brazilian population regarding COVID-19. DESIGN AND SETTING: Cross-sectional survey-type study, conducted using a population sample from different Brazilian states. METHODS: A quantitative, descriptive and analytical approach was used. Sampling was done according to convenience and via snowballing. The data collection instrument was a knowledge, attitudes and practices system. RESULTS: 1,655 people from all over Brazil participated in the survey; 80% were living in the southern region and 70.15% were female. More than 90% had knowledge and good attitudes relating to the means of transmission, preventive care and symptoms associated with COVID-19, although their knowledge and attitudes were not fully reflected in daily practices, for which there was lower adherence (80%). Greater knowledge was correlated with older participants, larger number of children, female sex and marital status; better attitude, with female sex and complete higher education; and better practices, with greater age, larger number of children and female sex. CONCLUSION: A large part of the population has general knowledge about COVID-19, but not all knowledge was applied in practice. Older people, females and university graduates stood out as the best informed and most committed to controlling the disease.

This study aimed to evaluate the in vitro effect of homeopathic solutions Arsenicum Album 24CH; Calcarea carbonica 30CH; Kali iodatum 100CH;Phosphorus 3CH; Silicea 30CH; Staphysagria 6, 30 and 100CH; Spodoptera frugiperda 30CH; Sulphur 100 and 200CH and Thuya occidentalis 200CH on biological parameters of the fungus Metarhizium anisopliae . The solutions were diluted in sterile distilled water (0.1%) and were sprayed on the previously inoculated fungus on PDA culture medium. Germination, colony forming units, vegetative growth, conidial production and insecticidal activity of the fungus against larvae of Diatraea saccharalis (Lepidoptera: Crambidae) were evaluated. Homeopathic solutions did not affect negatively the parameters evaluated. Thus, all treatments were considered compatible to the fungus M. anisopliae.(AU)
O presente trabalho teve por objetivo avaliar o efeito in vitro das soluções homeopáticas Arsenicum album 24CH;Calcarea carbonica 30CH; Kali iodatum100CH; Phosphorus 3CH; Silicea 30CH; Staphysagria 6, 30 e 100CH; Spodoptera frugiperda 30CH; Sulphur 100 e 200CH eThuya occidentalis 200CH sobre parâmetros biológicos do fungo Metarhizium anisopliae. As soluções medicamentosas foram diluídas em água destilada (esterilizada) (0,1%) e pulverizadas sobre o fungo previamente inoculado no meio de cultura BDA. Os parâmetros biológicos avaliados foram: germinação de conídios, unidades formadoras de colônias, crescimento vegetativo, produção de conídios e atividade inseticida contra lagartas de Diatraea saccharalis (Lepidoptera: Crambidae). As soluções não afetaram os parâmetros avaliados. Todos os tratamentos foram considerados compatíveis ao M. anisopliae .(AU)
