As the world contends with the lasting effects of COVID-19, research into long COVID provides crucial insights into ongoing public health challenges. Janko Nikolich, MD, PhD, and the Aegis Consortium at the University of Arizona Health Sciences are addressing these issues from both a scientific and a systems perspective. The Aegis Consortium, which brings together experts from across health, government and community sectors, is dedicated to building a pandemic-resilient future for Arizona and the world.
Nikolich, a professor and head of the Department of Immunobiology at the U of A College of Medicine – Tucson, talked to the U of A Health Sciences Office of Communications about what that means and how it can be achieved.
What would a pandemic-resilient Arizona look like?
Pandemic-resilience means we would recognize a pandemic when it is at our doorstep and would have the systems in place to act to stop it. We have the opportunity now to look back on the worst days of COVID-19 and make sure we are prepared for the future in a way that we weren’t in the past. Science and technology can give us remarkable tools like vaccines and antibody tests that can be used to treat people and control outbreaks, but they can’t be effective if our society isn’t organized in a way to use them appropriately.
In a pandemic-resilient Arizona, everyone in the population would know exactly where to go to get tested and what to do if they were to fall ill. State and county health departments would be able to track where those individuals are, and a command center would be able to supply the CDC with timely updates about what is happening in Arizona. Basically, we would minimize the number of people infected and prevent as many deaths as possible. This will require collaboration with experts and decision-makers from across the state. We are inviting them to help devise strategies in crucial areas such as detection and surveillance, the health ecosystem, and climate and pandemics.
What is a health ecosystem?
Health ecosystem is a term that broadly and inclusively describes everyone involved in health services. We’re not just talking about hospitals and doctors. This would include every health care worker and every place where folks might seek help during a public health emergency. The health ecosystem encompasses everything from nurses in clinics to social workers making home visits to assisted living facilities.
According to the Environmental Protection Agency, many regions of the U.S. can expect to see a climate-driven degradation of air quality that can cause or worsen health problems, such as respiratory and heart diseases. Environmental changes can also directly impact how pathogens are transmitted.
In a pandemic-resilient Arizona, people would be able to find out which hospital has capacity for them. Every part of the health ecosystem would know best practices on how to respond and work together. This would keep a sick person from infecting multiple other people while they are trying to find care, as well as direct a sick person where to get fastest care towards recovery.
This kind of philosophy carries over to other kinds of disaster preparation as well. You wouldn’t isolate people in the case of an earthquake or fire like you would for a pandemic, but having that coordination and planning is vital when you have a surge of people who need medical aid.
How does the climate factor into pandemics?
Changes in the climate impact everything in the environment all the way down to microbes and how they are transmitted. We know that the dryness or wetness of the air impacts how long an airborne virus can survive. Climate and environmental changes also influence animal habitat, which can affect the spread of infectious diseases to humans.
For example, we know that West Nile virus cases regularly occur in Arizona. Thankfully, our dry weather usually keeps the mosquitoes carrying that virus inactive much of the year. But with a change in the climate, you could have more mosquitoes buzzing around for longer periods of time. Or, you could have mosquitos moving up into higher elevations, which means now they are infecting a whole new population of people.
In what ways do you think detection and surveillance be improved upon in the future?
Many contact tracing phone apps were launched in response to the COVID-19 pandemic. I think there is a lot of potential here, in both promoting these apps to more members of the public and improving on the technology. In the future, people could use an app to see when they’ve been exposed to a virus or other contagion, and then it could give them directions on what they should do next or where they should go.
Wastewater surveillance is another tool that we used and need to continuously use to give public health officials real-time information about outbreaks in an area. We also want to be able to monitor what is being transmitted in the air. We want to work with our health departments to make sure we aren’t missing anything when it comes to detection and surveillance.
What is your greatest challenge moving forward?
We realize many people are tired of talking about COVID-19 and would love to forget about it. I think it is human nature to do that after something terrible happens, but the only way to avoid repeating history is to learn from it.
I think there is so much we can learn from the COVID-19 pandemic. Our university had a robust response and was able to integrate with government agencies as things went along, but that integration didn’t exist beforehand. I feel we all have a responsibility to build on areas of opportunity and to learn from areas where we could do better. We can make Arizona a model for the rest of the nation.
We will not be spared from the next outbreak. It is inevitable. The only question is will we be able to recognize the threat and put precautions in place to stop it from reaching global levels?
