COVID-19 Delta variant

Dr. James Lawler held a news conference on August 5, 2021 to explain the Delta variant of COVID-19.

Protecting against the COVID-19 Delta variant

UNMC public health and infectious diseases expert James Lawler, MD, explains how the SARS-CoV-2 Delta variant attacks the respiratory system in particular and how the COVID-19 vaccines work to repel the highly contagious, rapid-spreading Delta variant. Cases are increasing in Nebraska because of low vaccination rates particularly in some rural areas.

Dr. Lawler is co-executive director of the Global Center for Health Security at UNMC. “People should be very concerned about the trends we are seeing,” Dr. Lawler said. “I’m concerned that this is going to be the worst phase of the pandemic yet.”

Genetic variants of SARS-CoV-2 have been emerging and circulating around the world throughout the COVID-19 pandemic and will continue to emerge as long as the virus is allowed to be transmitted from person to person.

The simulation work is part of UNMC’s ongoing work to develop content for the federal government’s medical first responder training as teaching tool about how COVID infects humans. UNMC’s iEXCEL team in the Davis Global Center created the animation with Peter Angeletti, PhD, of the Nebraska Center for Virology at the University of Nebraska-Lincoln, serving as subject matter expert.
