2 Californians died of coronavirus weeks before previously known 1st US death

(CNN)New autopsy results show two Californians died of coronavirus in early and mid-February -- up to three weeks before the previously known first US death from the virus.
Doctors try to untangle why they're seeing 'unprecedented' blood clotting among Covid-19 patients
These deaths now stand as the country's earliest two attributed to the novel coronavirus, a development that may change the understanding of how early the virus was spreading in the country, health experts told CNN Wednesday.
Two deaths in Northern California's Santa Clara County happened February 6 and 17, the county said Tuesday in a news release.
The previously understood first coronavirus death happened on February 29 in Kirkland, Washington.
Time line
• December 31, 2019: China reports mysterious pneumonia cases to the World Health Organization.
• January 7, 2020: China says the cases were caused by a new coronavirus.
• January 17: US starts screening for symptoms at certain airports.
• January 21: First US case confirmed in Washington state.
• January 31: US says it will deny entry to foreign nationals who've traveled in China in the last 14 days.
• February 6: A person in California's Santa Clara County dies of coronavirus; link not confirmed until April 21.
• February 17: A second person in California's Santa Clara County dies of coronavirus; link not confirmed until April 21.
• February 26: CDC announces what's then thought to be the first possible US case of community spread, in California.
• February 29: A patient dies of coronavirus in Washington state -- then believed to be the country's first novel coronavirus death.
The two in California had no known travel histories to China or anywhere else that would have exposed them to the virus, Dr. Sara Cody, the county's chief medical officer, told The New York Times. They are presumed to have caught the virus through community spread, she told the Times.
"That is a very significant finding," Dr. Ashish K. Jha, director of the Harvard Global Health Institute, told CNN's "New Day" on Wednesday.
"Somebody who died on February 6, they probably contracted that virus early to mid-January. It takes at least two to three weeks from the time you contract the virus and you die from it."
If they did not contract coronavirus through travel abroad, that also is significant, Jha said.
"That means there was community spread happening in California as early as mid-January, if not earlier than that," Jha said.
"We really need to now go back, look at a lot more cases from January -- even December -- and try to sort out when did we first really encounter this virus in the United States," Jha said.
CDC confirmed Tuesday that tissue samples were positive
The Santa Clara County Medical Examiner-Coroner performed autopsies on two people who died in their homes February 6 and 17 and sent samples to the US Centers for Disease Control and Prevention, the county said Tuesday.
The CDC confirmed Tuesday that the tissue samples tested positive for coronavirus, the county said.
A third death in early March was also confirmed to be virus-related, the release said.
At the time of the deaths, the county said, testing for the virus was very limited -- generally restricted only to people with a known travel history and seeking treatment for certain symptoms, and available only through the CDC.
Further details on the victims were not provided.
The county said that as more deaths in the county are investigated, it's likely there will be more that are tied to the virus.
Dr. Colleen Kraft, associate chief medical officer of Atlanta's Emory University Hospital, agreed with Jha about the announcement's significance.
"That also means that a lot more people have had this, probably asymptomatically or with mild illness, than we thought before," Kraft said Tuesday.
