The World Health Organization (WHO) has warned that the Delta variant of coronavirus, which is now present in around 100 countries, will become the dominant variant of Covid-19 globally in the coming months.
The highly transmissible strain is “expected to rapidly outcompete other variants and become the dominant variant over the coming months”, the WHO said in its Covid-19 Weekly Epidemiological Update.
It further said that as of June 29, 2021, “96 countries have reported cases of the Delta variant, though this is likely an underestimate as sequencing capacities needed to identify variants are limited. A number of these countries are attributing surges in infections and hospitalisations to this variant.”
Given the increase in transmissibility, the WHO warned that the Delta variant is “expected to rapidly outcompete other variants and become the dominant variant over the coming months.”
The world body noted that the tools that exist today to combat the coronavirus individual, community level-public health and social measures, infection prevention and control measures that have been used since the beginning of the pandemic remain effective against current variants of concern (VOCs), including the Delta variant.
“Although the increased transmissibility of VOCs (Variants of Concern) means that measures may need to be maintained for longer periods of time, particularly in a context of low vaccination coverage, these measures must be targeted, time-bound, reinforced and supported by member states,” it added.
