"The best way to put out the fire is a vaccine, but that is over a year away. In the meantime, we must focus on reducing the height of the outbreak curve. This requires coordination and implementation of non-pharmaceutical interventions. School closures, isolation of the sick, home quarantines of those who have come into contact with the sick, social distancing, telework and large-gathering cancellations must be implemented before the spread of the disease in any community reaches 1 percent. After that, science tells us, these interventions become far less effective. Simply put, as evidence of human-to-human transmission becomes clear in a community, officials must pull the trigger on aggressive interventions. Time matters. Two weeks of delay can mean the difference between success and failure. Public health experts learned this in 1918 when the Spanish flu killed 50 million to 100 million people around the globe. If we fail to take action, we will watch our health-care system be overwhelmed."
