Published July 27, 2021, 12:12 AM General Community Quarantine (GCQ) “with heightened restrictions” has been imposed anew amid rising concerns over the dreaded COVID-19 Delta variant. The more restrictive regimen was imposed over Metro Manila, Ilocos Norte, Ilocos Sur, Davao de Oro, and Davao del Norte from July 23 to 31. Dr. Maurice Edsel Salvana, a noted infectious disease specialist, was featured in President Duterte’s televised weekly program to explain why the emergence of the Delta variant has prompted worldwide concern. In an eyeball: “Delta is more transmissible, potentially deadlier, and can spread quickly faster.” According to latest data, Delta is 60 percent more transmissible than the Alpha variant, and three times more contagious than the original SARS-COV-2 virus. While on average a person infected with the original Wuhan (China) virus could infect another three persons, and the Alpha variant five more, Delta could infect eight more — with exponential effect.
