The Delta COVID-19 strain spreads as easily as chickenpox, with fully vaccinated people also transmitting the virus, The Washington Post has reported, citing an internal document from the US Centres for Disease Control and Prevention (CDC), expected to be published later on Friday.
The transmissibility of the Delta variant is almost as high as chickenpox, with each infected person, on average, infecting eight or nine others, according to the document.
Fully vaccinated people can transmit the virus as well as unvaccinated people, it also said. Vaccination, however, provides substantial protection against the virus, the document added.

“It cites a combination of recently obtained, still-unpublished data from outbreak investigations and outside studies showing that vaccinated individuals infected with delta may be able to transmit the virus as easily as those who are unvaccinated. Vaccinated people infected with delta have measurable viral loads similar to those who are unvaccinated and infected with the variant.” – CDC document cites delta variant’s ability to spread among the vaccinated – The Washington Post
