TUESDAY, June 9, 2020 (HealthDay Information) — The new coronavirus appears to have arrived in California numerous unique times, new genetic analysis indicates.

“We located out that there have been a number of introductions into California of unique lineages of the virus,” study chief Dr. Charles Chiu, professor of laboratory medication at the College of California, San Francisco, told CNN.

In the to start with couple weeks following the new coronavirus to start with appeared in the United States, it wasn’t spreading freely throughout California, but was released in a selection of separate incidents, according to the study released in the journal Science.

“It displays that there were being numerous unique sparks landing in Northern California, quite a few of which fizzled out probably because of to a mix of community wellbeing measures and luck,” evolutionary biologist Michael Worobey, who was not associated in the study, told CNN.

For the study, Chiu and colleagues analyzed the genomes of the new coronavirus that infected 36 persons in nine California counties.

One finding was that an outbreak that infected additional than seven-hundred persons on the Diamond Princess cruise ship in February most very likely originated with a single passenger who carried a strain that circulated extensively in Washington state and in other places, Chiu told CNN.

Another outbreak in Solano County was confined to a few persons — a client and two healthcare employees who cared for her. Call tracing and fast isolation of the new instances prevented even more unfold, according to Chiu.

Even though it can be a smaller study, it aids show how a couple instances can transform into a pandemic, and how fast response can quit the unfold, Chiu told CNN.
