CDC COVID-19 Delta variant
CDC PUBLISHED FACTS CDC statements: The Delta variant causes more infections and spreads faster than early forms of SARS-CoV-2. The Delta variant is more contagious than previous strains--it may cause more than two times as many infections. Vaccination increases your odds from infection or severe infection. Some data suggests the Delta variant might cause more severe illness than previous strains in unvaccinated persons. 2 non-USA studies concluded patients infected with the Delta variant were more likely to be hospitalized than patients infected with previous strains. Unvaccinated people remain the greatest concern but breakthrough infections do happen, but less often than infections in unvaccinated people. Fully vaccinated people with breakthrough infections, can transmit the Delta variant to others. CDC is continuing to assess data on the percentages of fully vaccinated people with breakthrough infections and numbers that were able to transmit the virus to others. SIDE NOTE: Early external non-CDC study data placed the fully vaccinated people with breakthrough infections at between about 0.14# to 0.16#. However, recent deeper studies due to the increased number of infections are claiming much higher numbers and percentages.For instance, data from the U.K. suggests the Pfizer vaccine is 88% effective at preventing symptomatic COVID-19 from the delta variant after two doses. Which is a a 12% GAP. CDC admits that a percentage of fully vaccinated people with Delta variant breakthrough infections can spread the virus to others. But the greater risk of transmission is still among unvaccinated people who are more likely to contract, and therefore transmit the Covid-19 DELTA variant. CDC makes it very clear in noting, vaccinated people appear to be infectious for a shorter period. In contrast, The Delta variant seems to produce the same high amount of virus in both unvaccinated and fully vaccinated people. However, like other variants, the amount of virus produced by Delta breakthrough infections in fully vaccinated people also goes down faster than infections in unvaccinated people. This means fully vaccinated people are likely infectious for less time than unvaccinated people. Posted by: NN2N1 2021-08-10 |
