EVERYDAY SCIENCE

Detailed explanation-1: -Measles and TB are airborne-exclusive diseases. There are several other diseases that spread through respiratory droplets, which can exist either in the air or on surfaces. These diseases include: Chickenpox.

Detailed explanation-2: -They may also fall on surfaces and then be transferred onto someone’s hand who then rubs their eyes, nose or mouth. Airborne transmission occurs when bacteria or viruses travel in droplet nuclei that become aerosolized. Healthy people can inhale the infectious droplet nuclei into their lungs.

Detailed explanation-3: -Airborne or droplet spread Sneezing, coughing, singing, and talking may spread respiratory droplets (aerosols) from an infected person to someone close by. Airborne infections can spread without necessarily having close contact with another person via small respiratory particles.

Detailed explanation-4: -Examples of pathogens that spread via droplet transmission include seasonal influenza virus, Corynebacterium diphtheriae (pharyngeal diphtheria), Neisseria meningitidis (meningococcal meningitis), Yersinia pestis (pneumonic plague), rubella virus (German measles), and Bordetella pertussis (pertussis) (1, 3).
