The following is a summary of some recent studies on Covid-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review. An experimental chewing gum that "traps" SARS-CoV-2 particles in saliva holds promise for curbing transmission of new variants of the virus, according to new data, as researchers prepare.
For more than 30 years, polymerase chain reaction (PCR) has been the gold standard in molecular diagnostic testing, detecting genetic material, such as those from a virus or from human DNA.
