How can we reduce or avoid SARS-CoV-2 dispersion?

The infection that may cause COVID-19, has airborne transmission via droplets. The rate of transmission is quite high, higher than common influenza. The preventive measurements in general for patients, healthcare workers and community are: Wash your hands often with an alcohol-based (>65%) detergent if your hands are not apparently dirty, and with soap and water if they are contaminated. Always wash your hands after contact with respiratory secretions; Avoid contact with eyes, nose and mouth; Sneeze and cough into a bent elbow or tissue and then throw it away; Wear a surgical mask if respiratory symptoms appear and wash your hands immediately afterwards ; Keep a distance of at least 1 m from patients with respiratory symptoms.
