The respiratory secretions of infected patients are the true focus of contagion. When these secretions reach the mouth, nose or eyes of a healthy individual, the chances of transmission are very high. In the Set of Informativos Telecinco, Carlos Jiménez, President of SEPAR, ensures that we must pay attention to what we touch, but we must be even more aware of personal contact. You must always attend to the authorities, avoid as far as possible being away from home and crowds. People with chronic diseases are a risk group, age is another factor to consider and smoking does not help either. Early detection at the start of an epidemic is vital. Fernando Simón ensures that the problem must be detected as soon as possible so that the curve, instead of growing, descends until it disappears.
