COVID-19 variants are spreading rapidly across the globe putting Europe and the U.S. on alert.
The Delta variant appears to be more transmissible than other mutations and is even impacting countries with high vaccination rates.
According to Europe's CDC, by the end of August, nine out of 10 infections in the EU will be the Delta variant.
Health officials have warned that the variant will quickly spread, mostly in younger generations, and have urged the public to get vaccinated as soon as possible.
In the UK, the country is facing a COVID-19 resurgence due to the Delta variant.
More than 16-thousand daily cases were reported on Wednesday the highest figure reported since early February.
UK health authorities identified 90-percent of new COVID-19 cases related to the Delta variant and has also seen 41 cases of 'Delta Plus' which is reported to be stronger than the Delta variant.
The emergence of the Delta variant has led the UK government to delay lifting COVID-19 restrictions by four weeks, until July 19th.
The Delta variant is also spreading in neighboring France.
"In France, the Delta variant represents between 9 to 10 percent of infections. It's a proportion that is, at first glance, comparable to what we observe in the United States and probably in Germany."
In the U.S., the Delta variant has been detected in all states except South Dakota.
America's top disease expert, Dr., Fauci, said in a briefing that the Delta variant makes up more than 20 percent of all new infections, and he expects that it will be the dominant strain in a matter of weeks.
Fauci has declared the Delta variant the 'greatest threat,' and said there could be a need for vaccine booster shots in the fall.
Meanwhile, the U.S. FDA said Wednesday that it will add a new warning about rare cases of heart inflammation in those who've gotten the mRNA vaccines from Pfzier and Moderna.
The CDC has also found a likely link between the heart condition and the vaccines, but it still says the benefits outweigh the risks.
