The only thing you have to do is the general measures that are recommended for everyone. If it is a virus that is transmitted by the respiratory tree, it is generally transmitted by those medium sized droplets that we transmit when we speak and in which the virus is found if we are infected. These droplets never reach a meter in distance. Therefore, simply keeping one meter away when talking to people is an effective measure of protection.
Then those droplets go to objects, to our hands because we cough or because we touch things that have been filled with droplets, and then what we have to do is wash our hands often. Soap, being a solvent for fats, perfectly drags these viruses away and eliminates them. So this is the best thing we can do, and if we don't have all these alcoholic sprays we can use them as long as the hands are already clean. With these two measures, we have more than enough to prevent ourselves.
But remember, if we are touching things that we don't know what state they have been in, try not to touch the eyes, nose and mouth which are the entry points of the virus into the body. These are very simple measures, very easy to do and which perfectly avoid the transmission of the virus. Measures for the general population, same measures for the population that is being treated or that is pregnant.
