More data in on how much higher the actual infection rate is and how many people never realize they were infected, herd immunity may be much higher than suspected - posted on another board, published by the Boston Globe, full article is hidden behind a paywall:

Results of random testing in Chelsea, MA

Nearly one third of 200 Chelsea residents who gave a drop of blood to researchers on the street this week tested positive for antibodies linked to COVID-19, a startling indication of how widespread infections have been in the densely populated city.

Sixty-four residents who had a finger pricked in Bellingham Square on Tuesday and Wednesday had antibodies that the immune system makes to fight off the coronavirus, according to Massachusetts General Hospital physicians who ran the pilot study.
The 200 participants generally appeared healthy, but about half told the doctors they had had at least one symptom of COVID-19 in the past four weeks.

But the Mass. General researchers ? who excluded anyone who had tested positive for the virus in the standard nasal swab test ? found that 32 percent of participants have had COVID-19, and many didn’t know it.

“I think it’s both good news and bad news,” said Dr. John Iafrate, vice chairman of MGH’s pathology department and the study’s principal investigator. “The bad news is that there’s a raging epidemic in Chelsea, and many people walking on the street don’t know that they’re carrying the virus and that they may be exposing uninfected individuals in their families.”
“On the good-news side, it suggests that Chelsea has made its way through a good part of the epidemic,” he said. “They’re probably further along than other towns.”

Chelsea covers only about two square miles, across the Mystic River from Boston. For generations, it has attracted new immigrants, and about 65 percent of its residents are Latino. Many live in three-decker houses, Ambrosino said, where it’s hard for people to isolate themselves. Many work in the hospitality industry and health-related fields, where exposure to the virus is greater. And a lot of them must go to work during the pandemic.
