Delta May Spread Like Chickenpox, Cause More Severe Infection: Reports

The Delta variant of the coronavirus may cause more severe illness than all other known versions of the virus and spread as easily as chickenpox, US media reports quoting an internal document from the US health authority said.

The document from the Centers for Disease Control and Prevention (CDC) outlines unpublished data that shows fully vaccinated people might spread the Delta variant, first identified in India, at the same rate as unvaccinated people, reports said.

The contents of the document - a slide presentation - were first reported by The Washington Post on Thursday.
