From a public well being perspective, the previous 23 months have been, shall we embrace, eventful in america. Greater than 70 million Individuals have contracted COVID-19, in accordance with the Johns Hopkins coronavirus tracker, and practically 900,000 have died of it. Because the Omicron variant peaks and begins to wane, epidemiologists are taking inventory of our present means to trace this virus, and decide what new instruments and knowledge we’ll have to cease the subsequent one.
In terms of knowledge and the COVID-19 pandemic, SAS epidemiologist Meghan Schaeffer is conflicted. The general public well being veteran is inspired by some issues, however the presence of huge gaps in our understanding of the virus’s unfold have been onerous to abdomen.
“It was completely astounding to see how a lot info was shared to start with and has been shared all through the pandemic, and the way a lot knowledge folks might entry and interpret, largely accurately,” says Schaeffer, who had a sophisticated diploma in public well being and epidemiology and in addition runs Aperio Statistical Consulting. “That was actually great for science as an entire. We shared not simply knowledge, however analysis info, pattern sizes. We began to see into analysis in a approach that we’ve by no means seen earlier than. So these are all good issues.”
However the COVID-19 pandemic has additionally expose large gaps stay in the best way we acquire, course of, and analyze knowledge about infectious ailments. One of many greatest issues is the disconnected nature of how info trickles up from hospitals to state departments of public well being to the federal authorities and the Facilities for Illness Management and Prevention (CDC).
“1m000%, sure,” Schaeffer says when requested concerning the difficulties in knowledge integration stemming from the assorted disjointed processes that hospitals and different healthcare suppliers use to report case counts and different knowledge. “This this to me is without doubt one of the greatest ache factors of the pandemic, and we can not enter one other state of affairs like this with the present state of well being care and public well being not interacting with one another in a productive approach.”

Due to a scarcity of a standardized knowledge assortment strategies in hospitals, which usually report back to state well being departments earlier than its rolled up by the feds, the COVID-19 case depend knowledge has been something however tidy. The editors at The Atlantic, after they cataloged the state of COVID-1i knowledge, dubbed it a “messy patchwork.”
What’s extra, sharing case knowledge has additionally been hampered by privateness safety legal guidelines, Schaeffer says. “We now have hospitals which can be utilizing Google Docs or shared drives, or different methods to disseminate info,” says Schaeffer, who can also be a Nationwide Public Well being Advisor with the CDC. “There are main, main medical choices being made on the idea of those paper and pencil counts, issues like distribution of PPE, allocations of medicines and vaccination sources.
“That may be improved. It completely might be,” she continues. “We now have the information and well being info exchanges, in digital medical data. We now have the extraction protocols to do that. We simply now must push healthcare to make these connections to public well being. And we additionally must equip public assist with the knowledge and the capabilities to obtain it.”
The shoddy state of COVID knowledge prompted analytics skilled Tom Davenport to co-author a August 2020 MIT Sloan Administration Assessment story, which discovered a dismal state of information. “One is compelled to conclude that the information wanted to handle the COVID-19 pandemic is successfully unmanaged,” Davenport and his co-authors wrote. “That is an acute downside, demanding pressing, skilled consideration.”
Issues haven’t gotten a lot better since that report was written. Schaeffer, who beforehand labored as an epidemiologist for the state of Iowa, says we’d like main investments in IT infrastructure to carry state and federal programs up to the mark.
Knowledge issues have hampered the COVID-19 response from the CDC and different public well being establishments
“The US response has been tough. It’s been tough to be part of it. It’s been tough to look at,” Schaeffer tells Datanami. “As somebody who’s labored in public well being for a very long time, I bear in mind the plans that we created when the primary SARS got here out submit 9/11. We had response plans for all of this–all of those situations, even organic weapons.
“When COVID got here round, these plans had been nowhere to be discovered and it wasn’t one administration or politicians fault,” she continues. “There have been a number of successive administrations that lowered the funding in public well being lowered workforce, took away software program and coaching, and that’s resulted in the place we are actually.”
Expertise has superior considerably for the reason that public well being neighborhood’s final main funding in IT practically twenty years in the past. We now have confirmed the potential to successfully retailer tens of petabytes in distributed clusters, sustaining lineage and governance. We are able to analyze enormous quantities of information whereas defending privateness, and construct enormous AI fashions to foretell the longer term with typically astonishing accuracy.
The CDC is working to replace its knowledge property. At the moment, it has greater than 700 databases, Schaeffer says, and is implementing a knowledge lake. It’s additionally working with a number of educational companions to construct a brand new forecasting middle. It’s an excellent begin, however extra must be accomplished, she says.
“Widespread knowledge lakes have been round in industrial business and personal sector for many years,” she says. “So sure, they want precise bodily infrastructure, however in addition they want analytic instruments and capabilities and skills and workers to have the ability to construction these programs and extract the information in a significant approach.”
Different varieties of knowledge assortment have been a blended bag. The US was behind the eight-ball virtually from the get-go when the CDC’s first COVID-19 take a look at failed. These days, we’ve seen a surge within the availability of pretty correct COVID-19 take a look at kits, however that isn’t sufficient.

“From an epidemiological standpoint and having labored in public well being for 20 years, primarily in influenza, I used to be at all times shocked by the quantity of data that you could possibly get actual time, however [also the scarcity] of the large items of data that we critically wanted that we couldn’t get, and I actually, I really feel that approach now too,” Schaeffer says.
The US response might have benefited from extra sentinel reporting to COVID-19, which would offer a extra goal view into the extent of viral unfold in a area in comparison with voluntary testing, which is topic to the whims of individuals and subsequently strikes up and down primarily based on public sentiment.
“So far as what continues to be lacking in my view, what we have to begin transferring into is how will we survey in a sentinel method,” she says. “How will we arrange key markers to the place we’re not testing tens of millions and tens of millions of individuals each single day to evaluate this case.”
One knowledge assortment effort that has borne fruit in the course of the COVID-19 pandemic is wastewater testing. As a result of the extent of viral shed in sewage is basically proportional to the quantity of virus in people, wastewater monitoring has been a go-to supply for extra correct views of the pandemics peaks and valleys, notably in the course of the newest surge.
“Wastewater surveillance is a very highly effective software, and we’re seeing actually an excellent instance of that with Omicron,” Amy Kirby, this system lead for the Nationwide Wastewater Surveillance System, instructed the New York Occasions. “It’s not simply an early warning signal, however it’s additionally useful to observe the total trajectory of a surge.”
The CDC established the Nationwide Wastewater Surveillance System within the fall of 2020, and its ramping up actions by means of state, native, tribal, and industrial entities. One firm that’s on the forefront of wastewater detection is Biobot Analytics, is a non-public firm primarily based in Cambridge, Massachusetts.
“It’s a kind of information that we’re all creating, naturally, organically, once we are utilizing the restroom,” Mariana Matus, the chief govt and co-founder of Biobot Analytics, instructed the NYT.

Armed with knowledge from wastewater monitoring, we’ve been in a position to doc the unfold of the Omicron variant over the previous two months extra precisely than earlier surges. That knowledge, along with knowledge collected by South African researchers, has allow public well being officers within the US and different international locations to offer pretty correct forecasts for Omicron’s steep rise and equally steep fall, which we’re now witnessing on the East Coast.
“I believe we had been in a position to get a way of the magnitude of this unfold,” Schaeffer says. “We had been in a position to assess its transmissibility, the length of this peak.”
Just like the 10- to 14-day climate forecasts that meteorologists from america and Europe generate from ensemble fashions on supercomputers, the forecasts of Omicron’s unfold have held up. However past that, the view stays hazy.
Individuals could really feel blindsided by COVID-19, however we’ve benefited from a number of near-misses in terms of respiratory viruses with the potential to turn out to be international pandemics. Two different novel coronaviruses, SARS and MERS, largely prevented the US, whereas the swine flu (H1N1) epidemic of 2009 additionally (fortunately) petered out earlier than changing into a world pandemic.
As COVID-19 (hopefully) retreats into an endemic state, Schaeffer encourages us to maintain our guard up. There may be presently a looming risk of avian influenza that threatens to develop, to not point out all kinds of mosquito-born sicknesses from the tropics prepared to maneuver north and trigger bother.
“The extra folks work together with one another and have worldwide journey and work together with animals too, and the extra we disrupt the ecosystems that animals stay in, the extra these viruses and micro organism are going to alter, emerge, and have an effect on human well being,” she says. “So we simply we have to put together for it. As a result of it’s only a matter of time.”
