The delta variant of the coronavirus is now considered the dominant strain in the country, according to experts. It is believed to be around 60 percent more transmissible than the alpha variant, which was previously dominant around Connecticut and the U.S. The delta variant originated in India.
Gov. Ned Lamont announced on July 28 that Connecticut currently has a 2.94 percent COVID test positivity rate — the highest single-day positivity rate since May 5 — and has an additional 391 cases. This week the CDC revised recommendations to state that some fully vaccinated people should wear face coverings indoors in places that are considered high risk; Connecticut is one of these places as of now.
