More than 600 million cases worldwide: COVID-19 has changed the world.
Though there are still those who’ve dodged it.
COVID-19 “superdodgers” who’ve been exposed to the virus plenty but never got sick.
The Centers for Disease Control and Prevention estimates nearly half the population has never caught the virus and some scientists are working to learn why.
At the University of California San Fransisco and Rockefeller University in New York, researchers are studying to see if genetics play a role.
At Marquette University, assistant professor Dr. Nilanjan Lodh studies human genetics and infectious disease.
“There might be something physiologically going on there, which is good to know,” Lodh said.
He thinks physicians could use the genetic information for future medicine, he doesn’t believe people are simply born with superdodger immune systems.
“Kind of like the course of your actions throughout your life, that helps the immunity build up slowly,” Lodh said. “It’s not like one-day stuff. You’re acquiring that immunity over time.”
Lodh said what we eat, how often we exercise, where we live and what viruses we’ve been exposed to all contribute to one’s current immunity.
