 * 26 Aug 2021, CDC.gov, Delta variant: what we know about the science, The Delta variant is more than 2x as contagious as previous variants. Some data suggest the Delta variant might cause more severe illness than previous strains in unvaccinated persons. Although breakthrough infections happen much less often than infections in unvaccinated people, individuals infected with the Delta variant, including fully vaccinated people with symptomatic breakthrough infections, can transmit it to others. CDC is continuing to assess data on whether fully vaccinated people with asymptomatic breakthrough infections can transmit. The greatest risk of transmission is among unvaccinated people who are much more likely to contract and, therefore, transmit the virus.
