The CDC-led team also found that cases among American Indians and Alaska Natives tended to be younger in age.
The report included data on 340,059 Covid-19 cases confirmed between January 22 and July 3 from across 23 states. The researchers — from the CDC and other institutions across the United States — took a close look at race and ethnicity information for those cases.
Among American Indians and Alaska Natives there were 594 Covid cases per 100,000 people. That compares to, among White people, just 169 cases per 100,000, the team reported on Wednesday.
Data were limited to cases that included race and ethnicity information. The study also only compared coronavirus rates among American Indians and Alaska Natives to White people and not to other groups, as the pandemic also has hit Black and Hispanic communities at disproportionate rates.
The CDC said Wednesday that it has provided more than $200 million in Covid-19 funding to American Indian and Alaska Native communities to support pandemic preparedness and responsive efforts, such as surveillance, laboratory capacity and infection control.
Covid is impacting social issues as well, he said, and families have been hit hard by the pandemic across many generations.
“There are entire families that have either been infected with it, or have had multiple deaths in the family, all at once. And that is going to create a trauma that’s going to be long lasting and a need for mental health services,” he said.
“We cannot flip back into complacency,” Sequist said, adding the circumstances that created the crisis “existed long before Covid, and will persist long after unless we take decisive action starting today.”
