Delta variant ‘more contagious than the common cold and Ebola’

The Delta coronavirus variant is now believed to be more transmissible than the common cold or seasonal flu, sparking global concern as countries struggle to vaccinate their populations.
The fast-moving variant is already causing havoc in Australia, with NSW and Queensland fighting to control its spread with lockdowns.
US health officials have declared that “the war [against COVID-19] has changed” because of the highly contagious and most likely more severe variant.
Internal documents from the US Centers for Disease Control and Prevention (CDC) say the Delta variant is “as transmissible as chickenpox” and spreads more easily than the common cold, influenza (including the Spanish flu), Ebola and smallpox.
