To answer this question, I would like to say everything has its upside and downside.
I agree that civil aviation bring people closer but the movement of aircraft also increase the rate of disease’s outbreak.
Like coronavirus and tuberculosis, some commutable disease are contagious sickness that is spread by expelled droplets and manifests itself as a fever and persistent cough.
Air transport has an uneasy relationship with contagious illness. Increasing aircraft range, alliances, codeshares, low-cost and simplified travel all serve to assist the swift carriage not only of passengers but whatever they might harbour.
