The new strain isn't believed to be any more deadly, in-and-of itself, however, it is said to be up to 70% more transmissible.

"The ability to get from one half of the world to the other half in less than a day, somebody who is asymptotic can easily carry this infection and not even know about it," said infectious disease specialist Dr. Suman Radhakrishna.
The strain has also been confirmed in Colorado and in California.
The Florida case is a man in his 20s who lives in Martin County. Officials said he had a known travel history, but did not elaborate.
"If I were a betting man; I'm not, but if I were a betting man, I would say it is already here in Tampa somewhere," said University of South Florida associate professor of medicine Dr. Michael Teng.
Even if that proves to be the case, there is still some good news. The vaccines should work on the new strain.
So, too, do the safety measures we've become accustomed to.
"Wear a mask, wash you hands, social distancing, all those things will still work against this virus. The only concern really is people who are not doing those public health measures," Dr. Teng said.
