What we know about the Covid-19 Delta variant first found in India

The B.1.617.2 strain, officially known as the Delta variant, is worrying health officials across the world, including in the United States.
The Delta variant now accounts for more than 6% of sequenced virus samples in the US, according to data from the US Centers for Disease Control and Prevention.
Experts believe the Delta variant sparked the huge wave in infections seen across India over the past two months.
Experts now believe the Delta strain is likely more transmissible.
Hancock said last weekend the strain is "around 40% more transmissible" than the formerly dominant Alpha variant, which was already more transmissible compared to the original strain of the virus.
Early evidence suggests the Delta variant could cause an increased risk of hospitalization in comparison to the Alpha strain, according to Public Health England (PHE).
There is evidence the existing Covid-19 shots are working against the Delta variant.
They, too, appeared to be effective against the Delta variant once both doses have been administered.
Researchers note that sometimes a dominant strain is simply the variety that happens to ride a wave of transmission fueled by travel and mingling.
The UK, where the Delta variant is now dominant, is providing something of a cautionary tale for the rest of the world.
The fast spread of the Delta variant has prompted France and several other countries to place new restrictions on travelers coming from the UK.
India is a leading maker of vaccines but when cases started to spike, its government restricted the export of Covid-19 shots.Source
