What are the different types, i.e., Delta and Lambda(also known as India, South African, Brazil versions)? Are they a new virus? With different characteristics?
And have they been isolated?
I did not hear about how “they” determined it is Delta or Lambda, or original. Is there a new test? Doe’s the delta version wear a kilt?
Are we being lead down a rabbit hole?
The delta and lambda are variants of the same SARS-CoV-2 virus. These are very minor differences. The variants are 99% identical if not more.
The family is called beta corona viruses and includes the first SARS virus (Severe Acute Respiratory Syndrome) (SARS-CoV-1) and the MERS virus (Middle East Respiratory Syndrome virus).
SARS and SARS2 viruses are about 75% identical.
They all enter cells by the spike protein binding to an enzyme called ACE2.
