“I worry about people making their own sanitizer as it will be difficult to make sure that the concentrations are correct,” Daniel Parker, assistant professor of public health at the University of California, Irvine, told CNN of the trend. … The best way to prevent transmission of the novel coronavirus is still with good old water and soap. Parker advises that people wash their hands thoroughly for at least 20 seconds, avoid touching their face, cover their mouth when sneezing or coughing, and regularly clean surfaces.
