RESUMEN
The World Health Organization declared the novel coronavirus (COVID-19) outbreak a global pandemic on March 11, 2020 due to its rapid spread on a global scale. More than 118,000 cases had been reported in 114 countries, and mortality had reached a total of 4291. Scholars have suggested that the level of panic is correlated with knowledge and attitude among the population. This review presents a summary of knowledge, attitude, and practice during the COVID-19 pandemic among healthcare workers, medical students, and populations in the US, the UK, Italy, Jordan, and China in April 2020. Analysis reveals that the level of the knowledge was positive in general, and optimistic attitudes and good practices are held. Utility of substantial knowledge and positive attitudes and practices hopefully can control the spread of COVID-19.
