It's spread is pretty similar with the common cold, so be aware of the following:

1. close contact with infected individuals (that's why is so important to keep some social distance, being closer to someone means increasing the probability of propagation).

2. surface particles (that's why cleaning and desinfecting surfaces as tables, handles, atms, etc is so important

3. it spreads through airborne particles, saliva is dangerous (that's why, unlikely what some say, wearing a mask is a very simple and good measure to be safe), depending on the type of mask and how it's used protection will vary, however its use is recommendable.
