Maps, like this one from Johns Hopkins University, are 'meaningless'.
Pima County Health Director Dr. Bob England said the county has recently received a lot of requests to release some kind of geographic data relating to who’s tested positive for COVID-19 and cautioned residents to not look to such data for any meaningful information.
Because the amount of testing that can be done is tied to the limited number of tests available, even the known case count is an under-representation, Dr. Engald said.
“For every case we’re reporting, there are probably 50, maybe even 100 others of milder illness or asymptomatic infection out there,” he said.
Considering the potential for widespread infection, England said any effort to map cases would be “truly meaningless.” He added that any records would only contain home addresses of sick residents, not where they were infected.
“If there are 20,000, maybe 40,000 people with this infection in Pima County at this point, if you live in Marana—it’s up there,” England said. “If you live in Green Valley, it’s up there. If you live in the foothills, it’s there. If you live downtown or in South Tucson, it's everywhere.”
Even though he said such an effort would be fruitless at this time, England expects the county to perform such a task in the future.
