Delta can really F**K you up even if you aren't dying from it. There is wide variability in how much or how little COVID Delta can affect those bitten in breakthrough. It is NOT to be taken lightly that there are breakthrough infections. Currently we are seeing at least twice the rate we recently were told to expect. In addition 99% of all new infections in Montana are reported to be Delta variant, while the rate of full vaccination is just over 50%. Which means that half the people who you encounter ANYWHERE you go are likely not to be vaccinated, more in some counties than others. The 2 counties I live in and travel through are at 50% and 61% respectively.
B.1.1.529 is likely to have evolved during a chronic infection of an immuno-compromised person, possibly in an untreated HIV/AIDS patient, said Francois Balloux, director of the UCL Genetics Institute. With 8.2 million people infected with HIV, the most in the world, South Africas efforts to fight the coronavirus pandemic has been complicated, as immuno-compromised people can harbor the virus for longer, scientists say. De Oliveira has previously said that the Beta variant, a mutation identified last year in South Africa, may have come from an HIV-infected person.
