It’s no exaggeration to say the government is after your blood.
Officials say a new antibody test will help them understand the spread of COVID-19—and potential immunity to the disease.
Though most West Valley public schools remain in online-only mode, recent data is giving districts confidence to inch forward with plans to reopen classrooms.
Some parents, like Wendy Ellis-Bailey, are more than ready. Responding to a poll on the West Valley View’s Facebook page, Ellis-Bailey gave remote teaching an “F” grade. “This is ridiculous. Can’t wait for school to open in October. The children NEED proper teachers,” she wrote.
Nadia Pineda, the mother of a kindergartener, agreed: “It is really hard for her to focus.”
Those eager for schools to reopen will anxiously await results of a county-wide survey.
This week, Maricopa County Public Health is finalizing a new “serosurvey.” The random test includes Avondale (85323 ZIP code), Tolleson (85037), Glendale (85304) and Peoria (85382).
“Our goal is to get a random sample of Maricopa County,” said Dr. Rebecca Sunenshine, the county’s medical director for Disease Control.
She stressed that 30 communities around the county were selected randomly, with a goal of seven participants in each community.
Residents received a door hanger to notify them of their eligibility for participation. Those who volunteer to participate will do a blood draw—either in a small tent set up outside their homes or at a lab, as they prefer.
The Mayo Clinic will test the blood for COVID-19 antibodies.
“It will show presence of antibodies to COVID-19, which indicates you had or have COVID-19,” Sunenshine said.
Participants will receive their test results by phone within two weeks.
Meanwhile, the county will analyze the data to get a “big-picture” view of the spread of coronavirus.
The presence of antibodies is key, as many who have COVID-19 may not know it, due to mild symptoms or none at all.
“Especially early on in the pandemic, not everyone who was infected was tested. We also know that around 40% of people infected with COVID-19 never develop symptoms and may not be included in our case counts,” said Marcy Flanagan, executive director of the county’s Public Health Department.
Sunenshine said this will help with vaccination planning.
“The goal of this is for us to understand a county-wide perspective of the portion of the population with antibodies, which tells us how likely they are to have some immunity and how many people we would have to vaccinate,” Sunenshine said.
She added, “That information is helpful to know when we can relax social distancing and mask requirements.”
Asked how long she thinks antibodies will provide immunity to COVID-19, Sunenshine hedged. “I would not feel comfortable answering that,” she said, noting the disease is in its early stages.
“But we know that literature supports that most people who have had COVID-19 do develop antibodies and have some protection. ... We’re all pretty confident that protection lasts at least three months.”
According to the Maricopa County COVID-19 data tracker, the county has been collecting data on the coronavirus for eight months, with nearly 140,000 positive test results.
In addition to the general site, in the last month the county launched a School Reopening Dashboard and Guidance site. Both reflect positive trends, with results showing the spread of coronavirus slowing from previous months.
The West Valley View asked Sunenshine how she interprets recent data.
“Overall, the trends we’re seeing in the county is that we peaked and our percentage positive rates are down probably about the lowest we think we will see them—and we have now plateaued,” she answered.
“... We need to keep up social distancing, wearing masks and staying home when we’re sick in order to keep at low levels.”
With many West Valley schools planning to reopen schools in two weeks, the West Valley View asked Sunenshine what her expectations are for community spread once students return to classrooms.
“Generally, it takes at least two weeks before we start to see an impact on numbers from a change in scenario, whether that’s opening schools for in-person learning, interventions to reduce spread, or anything else,” she said.
“We have been working with schools regularly to offer guidance on how to reduce risk to students and staff when classrooms reopen. If there are cases in schools, we will work closely with the school to ensure they have guidance to stop COVID-19 spread.”
