According to estimates released
by the Centers for Disease Control and Prevention
, the delta variant
of the coronavirus
is likely the most common strain of COVID-19
in the United States
estimated that 51.7% of new cases in the two-week period ending July 3 were linked to the delta strain, while 28.7% were linked to the alpha strain, which has been dominant in the United States throughout the pandemic
. The tallies are projections based on case modeling, and official breakdowns will be released in full later this month.
However, COVID-19 cases linked to the delta variant have skyrocketed in some areas of the country, particularly in states with lower vaccination
rates, with the CDC predicting that more than 80% of new cases in the region encompassing Kansas
, Nebraska, and Iowa
would be linked to the strain.
officials announced earlier this week that the delta variant was the most prevalent strain found in new cases, accounting for more than 35% of all infections as of June 21, up from 5.6% in May.
officials have urged Americans to get vaccinated in response.
The World Health Organization
also declared that the delta strain was the “most transmissible” that health officials had identified thus far, and chastised vaccine rollout efforts in low-income countries for fueling a rapid rise in global cases.
Some countries' COVID-19 response plans have already been hampered by the delta strain.
Lockdown orders have been extended for millions of Sydney residents as a result of a troubling chain of cases linked to a man infected with the delta variant.
Bangladesh has extended its current curfew into next week as border
with an influx of patients infected with the delta variant.
On Monday, Fiji reported a record 636 COVID-19 infections and 6 deaths, causing the mortuary at the Pacific island nation's main hospital to fill to capacity. Fiji has reported a total of 39 deaths since the pandemic began, with the majority occurring since the emergence of the delta variant in April
And, despite the fact that the delta variant is responsible for 95% of new cases in the United Kingdom
, the government announced plans to put the country's high vaccination rate to the test on July 19 with a nearly full reopening of society.
, and Johnson & Johnson vaccines
have all been shown in studies to be effective against the strain in varying capacities. The Biden administration
announced a new summer-long push on Tuesday to vaccinate Americans who are still hesitant to get inoculated, including going door-to-door in some areas.
