After clearly looking the spread of disease world wide i have serious doubt on mode of transmission of COVID-19 It is not transmitted through air, water etc. The COVID-19 transmitted when a person come to direct contacts with the sneezing or coughing droplets of infected person's. or When person hand touches infected area and then with the same hand touch's to his/her nose or eye. I wont this a disease with this type of transmission can cause this huge disasters. Please add your feedback, this help in making a proper plane in controlling the disasters.
Main transmission of SARS-CoV-2, the virus causing COVID-19 pandemic, is by respiratory droplets. Because these respiratory drops will be suspended near a COVID-19 patients and will also settle on surfaces, the contact to such contaminated surfaces, can also be a secondary mechanism in transmission of this virus.
Therefore, using a mask by a COVID-19 (to prevent spreadinto g the infection to others), and by other people who may be coming near a COVID-19 relatively asymptomatic undocumented patient can reduce the spread of COVID-19.
Washing hands for 30 minutes with a soap, or sanitizer after touching any surfaces and using paper tissue to contain the virus.
These are the measures recommended by WHO and CDC and all major health agencies (1-2).

Current evidence suggests that COVID-19 spreads between people through direct, indirect (through contaminated objects or surfaces), or close contact with infected people via mouth and nose secretions. These include saliva, respiratory secretions, or secretion droplets.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19, predominantly spreads through air.
