No evidence homegrown variant is fueling coronavirus surge in the US, CDC says – CNN

“Additionally, there is a strong possibility there are variants in the United States; however, it could weeks or months to identify if there is a single variant of the virus that causes COVID-19 fueling the surge in the United States similar to the surge in the United Kingdom,” the spokesman added.

“Researchers have been monitoring U.S. strains since the pandemic began, including 5,700 samples collected in November and December. To date, neither researchers nor analysts at CDC have seen the emergence of a particular variant in the United States as has been seen with the emergence of B.1.1.7 in the United Kingdom or B.1.351 in South Africa.”

It was not immediately clear why the White House issued a statement in print to states speculating about a new variant of virus arising across the US. An administration official told CNN’s Jim Acosta the speculation started on a call with governors.

CNN obtained multiple copies of written statements sent to states last week.

“This fall/winter surge has been at nearly twice the rate of rise of cases as the spring and summer surges. This acceleration suggests there may be a USA variant that has evolved here, in addition to the UK variant that is already spreading in our communities and may be 50% more transmissible,” the report reads.

“Aggressive mitigation must be used to match a more aggressive virus; without uniform implementation of effective face masking (two or three ply and well-fitting) and strict social distancing, epidemics could quickly worsen as these variants spread and become predominant.”
