The more contagious Delta variant of COVID-19 has now dominated California as it becomes the most identified strain. 

In new data released by the California Department of Public Health, health officials say they identified that 35.6% of all coronavirus cases analyzed in June were caused by the Delta variant, first identified in India. 

In comparison, health officials reported that only 5.6% of all analyzed cases in the state in May were caused by the more contagious variant. 

Delta Variant

The Delta variant, previously referred to as B.1.617.2 variant, was first identified in India and was linked to a devastating surge of COVID-19 cases in the country. 

A study published by Public Health England in early June suggested that the variant was at least 60% more transmissible than the Alpha variant, which was first detected in the United Kingdom.
