Monday's reports home in New York City's death toll and California airports at screening for the virus.
In New York City, the virus can directly or indirectly kill far more people than the city's official death toll shows, according to one of the two reports.
Researchers found that while the city reported 24,172 more deaths since mid-March compared to what is normally expected, only about 19,000 of them were directly linked to the virus.
And while it's hard to track why the other 5,000 deaths occurred, the report says one reason may be that "social distance practices, the demand for hospitals and health professionals and public fears related to COVID-19 can lead to delays in seeking or achieving life-saving care. . "
These findings add a growing body of evidence that highlights how the pandemic can kill Americans without ever infecting them. Experts, for example, have also said that a decline in reported heart attacks and strokes across the country is likely a result of people avoiding emergency services.
In the second report, researchers say that airport screening of travelers from China and Iran failed to prevent the spread of the virus, at least in California.
More than 11,500 travelers were screened and monitored, but only three ended up testing positive, according to a team from the California Department of Public Health.
The program's effectiveness was limited by "incomplete traveler information received by federal officials and transferred to states, the number of travelers in need of follow-up, and the potential for presymptomatic and asymptomatic transmission," the report states.
Managers push forward with reopening
At the beginning of next week, 48 states will have relaxed at least some measures as the country moves toward reopening – but there is still heavy debate around whether it is safe to start carving a path to normalcy yet.
Experts and public health authorities have for weeks warned that premature release of measures could cause the US death toll to increase by thousands.
But business owners and some local officials across the country have demanded that home-based orders be lifted to avoid a crash in the economy – amid an already unprecedented amount of unemployment claims in many states.
In California, where the governor created guidelines last week for regions to meet before starting to move toward reopening, San Diego officials said their city is ready to go back to business.
"I admire the governor and the work he's done, but I think the standard he set last week, not to leave businesses open unless the counties have gone two weeks without deaths is unrealistic in any city county, "said San Diego County Supervisor Greg Cox." We will certainly cooperate with him in a cooperative way, but we must have standards that are achievable. "
In Louisiana, Prime Minister John Bel Edwards announced Monday that he will abolish the state's home visitation scheme Friday, adding that the state would move into phase one of its reopening plan.
Restaurants, casinos, churches, hairdressing salons and gyms are some of the businesses that can open with restrictions in the first phase, but are limited to 25% occupancy and must practice social distancing.
And in Hawaii, state officials are considering starting to take photos of all visitors flying into the state as they continue to tackle violators of the mandatory 14-day quarantine currently in place for travelers.
"If we know that someone has quarantined, we do not (yet) have a picture we can distribute and get people to help us identify who they are," Prime Minister David Ige said in a Facebook forum with the Honolulu Star newspaper – Advertise Monday.
The governor of South Dakota requires that coronavirus checkpoints be removed
In South Dakota, where no home order was ever issued, two Native American tribes have refused to remove checkpoints they put in place to protect reservations against the spread of the virus, despite pressure from the governor.
The Government of Christ gave the tribes 48 hours Friday to take down the checkpoints from US and state highways. Both tribal leaders refused, and the governor accused the communities on Monday of stopping essential traffic and initial reactions.
"Delivery of gas, medical equipment and food is incredibly important to make sure we have made it through these areas," Noem said, adding that some travelers who just wanted to travel through the checkpoints were turned around.
The tribes disputed CNN's charges and the governor said Monday that she would not "give any concrete stories today."
"We are not receiving complaints, and the governor has not shared any specific complaints with us," Remi Bald Eagle, spokesman for the Cheyenne River Sioux Tribe, told CNN, adding "it is difficult to address the hearing defense."
On Sunday, Cheyenne River Sioux Tribe board chairman Harold Frazier told CNN that "99.9% of motorists are stopped in a minute or less and allowed to go through."
He said that if travelers "came from hotspots for no reason to be here – to travel without significant significance," then the tribe "has turned people back."
