As of March 20, more than 8,700 people worldwide had died of COVID-19, the disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Caltech trustee David Ho (BS '74) of the Aaron Diamond AIDS Research Center, Columbia University, says that this is just the tip of the iceberg. Ho, an expert on viral epidemics, has spent decades researching HIV/AIDS, having begun his career in Los Angeles, "ground zero" of the first outbreak, in the early 1980s. On March 18, Ho sat down with members of the Caltech community to discuss the novel coronavirus and the future of our society in the light of this global pandemic.
Walk us through the spread of the virus in the United States. What does the country look like right now?
Let me just give you a picture of what I see here in New York. About two weeks ago, we had our initial case, and now in New York City newly diagnosed confirmed cases are tripling every two days. In our New York Presbyterian Hospital, approximately 25 percent of the swab samples that are submitted for testing are positive. In the suburban communities outside of New York, approximately 10 percent of the swabs submitted are positive. So, the virus is everywhere. And in New York, we know that we are in the exponential growth phase of the epidemic.
