At least 23 members of an Oklahoma State University sorority have tested positive for Covid-19, the school said in a statement on Saturday.

The outbreak happened at the off-campus house of the Pi Beta Phi sorority and was detected by rapid-antigen testing done at an off-campus clinic, according to the university.

The coronavirus doesn’t appear to have devastated America’s homeless population to the extent public health officials and advocates for the homeless initially feared.

Johns Hopkins reported 1,029 new deaths on Saturday from the virus in the US. According to the university’s tally, 169,489 people in the US have died from Covid-19 since the start of the pandemic with identified cases exceeding 5 million.

“I am shocked, I guess I can say, because it’s a very vulnerable population. I don’t know what we’re going to see in an aftermath,” said Dr. Deborah Borne, who oversees health policy for Covid-19 homeless response at San Francisco’s public health department. “That’s why it’s called a novel virus, because we don’t know.”

More than 200 of an estimated 8,000 homeless people in San Francisco have tested positive for the virus, and half came from an outbreak at a homeless shelter in April. One homeless person is among the city’s 69 deaths.
