Theoretically, one patient can transmit the virus to 2-3 individuals without safety precautions. Person-to-person spread is thought to occur mainly via respiratory droplets and contact. However, given the current uncertainty regarding transmission mechanisms, spreads via air and stool specimens remain unknown. Respiratory droplets transmission generally, face-to-face, talking, coughing, and sneezing can cause droplets to spread. Therefore, wearing a mask seems an effective prevention, as well as keep your distance from others as much as possible (at least 1-2 m).
Direct contact transmission refers to the transmission of the virus through direct contact of mucous membrane or skin.
Indirect contact transmission refers to the transmission caused by:
Touching contaminated objects, feces (such as stool, which has been still unsure),secretions (such as droplets accompanied by coughing and sneezing), or daily necessities (learning supplies, bedding, toys, tableware, clothing etc.), hands and the contaminated hands touch the nose, mouth and eyes and mucous membranes (therefore, washing your hands frequently is the most important precautionary measure).
