Why is Orange County seeing big surge in coronavirus? Experts trace spread of disease

Dr. Daniel Parker, an epidemiologist at the University of California Irvine specializes in mapping out infectious diseases. “This started in affluent communities on the coastal area,” Parker said. “These are people who may have had stronger ties to places in Europe that at the same time had epidemics going on.” … To help track the virus, UCI, the Orange County Health Care Agency and community-based organizations are training hundreds of people from the most-impacted communities to help trace the spread of the disease in their neighborhoods.
