Could the new, more contagious COVID-19 variant already be in Arizona?

With confirmed cases of a new coronavirus strain in both Colorado and California, could the strain be here in Arizona?

Experts agree it's likely more widespread throughout the country.

"We've known this has probably been around for a little while just because they've detected it recently. I think they've known since September it exists. There are some mutations to the coronavirus, that's not a new thing. These viruses mutate a lot more than people realize," said Dr. Ross Goldberg.

Dr. Ross Goldberg with the Arizona Medical Association and Valleywise Health says the biggest worry is how infectious the new strain is.

"The virus's job is to just spread, right? It wants to spread as easily as it can so it will adapt to its host and find ways to make itself spread faster and that's what it's doing here. It learned a way to make it spread faster between humans."

That doesn't necessarily mean deadlier, but different people handle COVID in different ways.

"There is still much to learn about this new strain. UK scientists have warned that it appears to be much more contagious. They've also found through studies that it is more likely to effect children," said Dr. Marjorie Bessel.

Much more research is needed, but many are still confident this won't derail vaccine progress.

"So even changing a small piece of it doesn't change the overall point of the vaccine. I know they're studying it now but we're pretty confident the vaccines will keep you safe against these new variants," Dr. Goldberg said.

The discovery of this known strain comes down to sequencing the virus.

The United States lags way behind other countries in mapping infections out, meaning the new strain could've been here for a while.
