CDC coronavirus testing decision likely to haunt nation for months to come


 

As the novel coronavirus snaked its way across the globe, the Centers for Disease Control and Prevention in early February distributed 200 test kits it had produced to more than 100 public health labs run by states and counties nationwide.

Each kit contained material to test a mere 300-400 patients. And labs, whether serving the population of New York or tiny towns in rural America, apparently received the same kits.

The kits were distributed roughly equally to locales in all 50 states. That decision presaged weeks of chaos, in which the availability of COVID-19 tests seemed oddly out of sync with where testing was needed.

A woman in South Dakota with mild symptoms and no fever readily got the test and the results. Meanwhile, political leaders and public officials in places like New York, Boston, Seattle, and the San Francisco Bay area – all in the throes of serious outbreaks – couldn’t get enough tests to screen ill patients or, thereby, the information they needed to protect the general public and stem the outbreak of the virus, whose symptoms mimic those of common respiratory illnesses.

Rapid testing is crucial in the early stages of an outbreak. It allows health workers and families to identify and focus on treating those infected and isolate them.

Yet health officials in New York and such states as New York, Washington, Pennsylvania, and Georgia confirmed that they each initially got one test kit, calling into question whether they would have even stood a chance to contain the outbreaks that would emerge. They would soon discover that the tests they did receive were flawed, lacking critical components, and delivering faulty results.

During those early weeks, the virus took off, infecting thousands of people and leading to nationwide social distancing and sheltering in place. Public health officials are just beginning to grapple with the fallout from that early bungling of testing, which is likely to haunt the country in the months to come.

Too little too late

The first shipment to Washington state arrived more than 2 weeks after officials there announced the first U.S. case of coronavirus, and at a moment when deadly outbreaks of the disease were already festering in places like the Life Care Center in Kirkland. Within weeks, three dozen people infected with COVID-19 would die at the nursing home in the suburbs of Seattle.

The spread of COVID-19 would not take long to overwhelm the state, which as of March 20, 2020, had more than 1,300 cases.

The Trump administration in recent days has attempted to speed testing for the virus after early missteps hampered the government’s response to contain the contagion, and officials have had to respond to a barrage of criticism from public health experts, state officials, and members of Congress.

Federal health officials have eased the process for university and commercial labs to perform their own tests, and they are ramping up their capacity. As of March 16, public and private labs in the United States had the ability to test more than 36,000 people a day, according to estimates compiled by the American Enterprise Institute, a conservative-leaning think tank in Washington, a figure expected to rapidly escalate in coming weeks. That figure, however, can vary considerably by state and does not indicate how many tests are actually given to patients.

“We are now beginning to see that they have spread out in a prioritized way. We asked them to prioritize the regions that were mostly affected,” Deborah Birx, the coronavirus response coordinator for the White House Coronavirus Task Force, said March 18 of private labs’ testing, without elaboration.

The scaling up of testing is set to take place after weeks of faltering and hundreds, if not thousands, of undiagnosed people spreading the virus. For example, New York’s state health department received a faulty CDC test kit on Feb. 8 for 800 patient specimens, an amount that’s consistent with other states, according to a spokesperson. It later began testing patients with a test that state officials developed based on the CDC protocol and has significantly increased testing – as of March 20, more than 7,200 people had tested positive statewide.

In New York City, the first batch was obtained on Feb. 7.

“The other state and local public health laboratories got test kits as they became available,” said Eric Blank, chief program officer of the Association of Public Health Laboratories.

Places in the middle of the country with no outbreaks had the luxury of time to plan. For example, Missouri officials have had about 800 tests to work with, leading to only 395 performed so far in the region by public health labs – 26 of which were positive. When private lab tests are accounted for, as of March 20 there were 47 confirmed cases.

Health care providers and public health staff in the state, however, benefited from the fact that there is less international travel to the region, according to infectious disease expert Steven Lawrence, MD, of Washington University, St. Louis.

“This is very similar to 1918 with the influenza pandemic – St. Louis had more time to prepare and was able to put measures in place to flatten the curve than, say, Philadelphia,” Dr. Lawrence said. “Seattle didn’t have an opportunity to prepare as much in advance.”

While commercial labs are coming online, strict restrictions are limiting testing capabilities, Dr. Lawrence said.

“The state has had their hands tied,” he added.
