Chloroquine and coronaviruses. Factors justifying the use of chloroquine in coronavirus infection
Coronaviruses are large RNA-containing viruses with a lipoprotein envelope. Glycoprotein protrusions in the form of pins - peplomeres, which are clearly visible on negatively colored preparations, protrude from the shell of viral particles. Initially, isolated coronaviruses are identified by their characteristic morphology using negative contrast at an increase of x 90,000.
