As the number of coronavirus cases continues to climb in California and around the world Friday, public health officials called for increasingly drastic measures in the face of the potentially lethal disease, urging residents to avoid large gatherings and business meetings and discouraging even casual human contact in an attempt to slow the virus’s spread.
