These findings are preliminary, however, and it is not yet known whether the virus remains viable after hitching a ride on pollution particles, or whether it can do so in sufficient amounts to cause infection. Through our lungs, it will cause already major damage, increasing the risk of chronic respiratory diseases: lung cancer, obstructive chronic pulmonary diseases, asthma, pneumonia, and others.
