It should be kept in mind that even a low viral load is enough for Covid 19 to attack a new host, so repeated hand washing and not touching the eyes, nose and mouth are recommended.
So beware of coughing, sneezing, close breathing of others, potentially contaminated surfaces of public places, and not taking food left uncovered in the air that could become contaminated with vaporized droplets from people in transit.
Always keep in mind that Covid 19 constantly seeks a living host in which to take root.
