Early data from the outbreak indicates that the ageing population, particularly those with pre-existing medical conditions, are more susceptible to infection. Nursing homes and elderly homes globally have reported community clusters. But the downside of that caution is the false sense of security that is sending to young people - especially those who are healthy. Our host James Chau speaks to Dr. Art Reingold, an epidemiologist at Berkeley with decades of first-hand experience with infectious diseases, including eight years at the US Centers for Disease Control and Prevention. He looks at the evolving outbreak in the US, and provides a balanced insight into different at risk groups, the impact of public health measures in different cultures, and the likelihood that it's going to take a turn for the worse without strong interventions.
