Delta variant of Covid one of the most infectious of all respiratory diseases, CDC director says

US has recorded close to 600,000 Covid-19 cases over the last four weeks

The Delta variant of Covid-19 is one of the most infectious of all respiratory diseases, the director of the Centres for Disease Control and Prevention (CDC) said on Thursday.

“The delta variant is more aggressive and much more transmissible than previously circulating strains. It is one of the most infectious respiratory viruses we know of, and that I have seen in my 20-year career,” CDC Director Dr Rochelle Walensky said.

Dr Walensky told reporters that “this virus has no incentive to let up, and it remains in search of the next vulnerable person to infect,” reported NBC News.
