An interesting facet of the novel coronavirus is how seemingly healthy people transmit the virus to others through asymptomatic spread. Not to be confused with pre-symptomatic transmission, it’s estimated by the Centers for Disease Control that about 40 percent of people infected with COVID-19 have no symptoms — ever.

We’re also learning more about our immune response to the virus. Early research points to a strong immune response, even in those who only showed mild symptoms.

MPR News host Kerri Miller talked with a doctor and immunologist about what we know about transmission, immunity and antibody response and testing.

Guests:

  • Dr. Monica Gandhi is a professor of medicine and associate division chief of the Division of HIV, Infectious Diseases, and Global Medicine at UCSF/San Francisco General Hospital.

  • Jennifer Gommerman is a professor of immunology at the University of Toronto’s Faculty of Medicine.
