Dr. Tedros Adhanom Ghebreyesus WHO's director general said that COVID -19 does not transmit or pass on as efficiently as Flu.

When a person with this virus coughs or sneezes and exhales then droplets of infected fluid land on nearby surfaces like table, chair, bed, telephone, desk, wall etc. Then it spreads by hand or touch from human to human. After that touching face, nose or eyes will cause infections to another person. Only barrier is hygiene and maintaining respiratory etiquette.
