California reported more than 7,000 new COVID-19 cases on Monday — the largest daily jump so far. Other parts of the U.S. are seeing COVID-19 spikes too, including Texas, Arizona, and Florida. This might be due to a small fraction of people infecting the majority of the population, according to James Lloyd-Smith, a professor of ecology and evolutionary biology at UCLA.
