Prevent or Prepare?

It is basically extremely difficult to avoid contracting the virus, as the masks available are not designed for this function according to WHO*. If you are in buildings with other potentially infected people or travel by bus, then chances are you will get infected. So, apart from isolating yourself at home I have no other suggestions for you other than not touching your eyes/nose/mouth with your fingers. The virus cannot enter your body through the skin of your hands. It can only enter by breathing or letting infected fingers touch your eyes, nose and mouth.

All that remains to be done is to physically prepare to fight the virus once you acquire it. The function of the immune system is double, it fights microbes and eliminates toxins. So, if you ingest toxins (flavorings, sweeteners, preservatives, non-organic foods, etc.) or if you suffer from constipation, then your immune system would already be too busy trying to keep your blood purified. People unknowingly become toxified by not drinking enough purified water, cooking with tap water, eating/drinking things with chemicals (sweeteners, preservatives, flavourings and so on), eating too many red meats and too few fruits. If you are making these mistakes, then you are giving the virus a better chance to cause worse symptoms. People also become toxified by not curing their constipation. If solid waste is not disposed of every day, then your body is permanently absorbing toxins from waste in the intestines. The cheapest and easiest way to correct this problem is to eat fewer red meats and cheeses, drink more water, reduce consumption of milk and carbonated beverages; and, take a teaspoon of table salt or magnesium salt in a glass of water. It also helps your immune system by not worrying about the virus and get more sleep at night.

* at the CDC web site it says: "You don't need to wear a face mask unless you're taking care of someone who's sick (and not able to wear a face mask).

At the WHO web site the page entitled "Basic Measures to Protect Against the New Coronavirus", it says nothing about the use of face masks.

FDA says this on their site : "While a surgical mask may be effective in blocking splashes and large-particle droplets, a face mask, by design, does not filter or block very small particles in the air that may be transmitted by coughs, sneezes, or certain medical procedures. Surgical masks also do not provide complete protection from germs and other contaminants because of the loose fit between the surface of the face mask and your face."

Cheap face masks were not designed to prevent virus from being inhaled, but for doctors who perform surgeries so they won't spit into their patients open bodies. That's why they're sometimes called "anti-spitting masks". The spacing between the fibers of these masks is too large to catch the smallest of spit globules floating in the air after being sneezed there. It will only catch the large globules. If the government is telling you to wear a mask before you get sick, then they're basically just giving you a pacifier, treating you like a baby. They want you to have a false sense of security.

But if you have symptoms of coronavirus, then you should wear a mask to prevent your infected spit from entering the air when you sneeze or cough.
