The World Health Organization has announced that the COVID-19 Delta variant is now in 132 countries.
The Delta variant is among the four COVID-19 mutations that WHO has designated “variants of concern”.
Others are the Alpha variant which is present in 182 countries, Beta in 131 and Gamma in 81 and after reaching eight new countries in the past week.
Studies have however shown a several-fold reduction in neutralization on the effectiveness of COVID-19 vaccines against the four variants of concern.
WHO also cited that several laboratory studies have shown that transmission to household members were reduced by approximately half when the infected person was vaccinated with at least one dose, compared to someone who hadn’t had any jab.
This even as the UN Health Agency stated that COVID-19 infections rose by 8% last week to more than 3.8 million.
This subsequently contributed to a sharp rise in the number of COVID-19 deaths overall, which climbed by 21% compared with last week, to more than 69,000.
