People affected by communicable diseases are advised against traveling on airplanes to prevent the spread of infections to others in close quarters. Airplanes have confined spaces and limited ventilation, making it easy for pathogens to transmit among passengers. Additionally, the risk of outbreaks increases when infected individuals travel, potentially leading to wider public health emergencies. Thus, restricting travel helps protect both the affected individuals and the public at large.
Communicable, infectious, and spreading are words. Those mean contagious.
The main advantage in a expanded program of immunization is that it prevents communicable diseases from spreading to new victims. Without new victims and hosts to grow and spread an outbreak of a communicable disease will naturally die out.

Gout is not a communicable disease therefore people can not spread it like a cold for instance.
hmmmm..... maybe you should try to keep your breath clean and not cough or sneeze on anyone
This sounds like a highly communicable illness called impetigo and should be treated with antibiotics.
Melanoma is a non-communicable disease and is not transmitted as an infectious disease is. It is the spreading of the disease.
It is a communicable disease that usually spreads from person to person directly or indirectly through the body secretions of the infected person that contain the virus particles. It is often passed along by respiratory droplets that contain the virus particles that are expelled by someone when they sneeze or cough. The virus can also live on surfaces such as a doorknob. A person touching an infected surface and then touching mucous tissue by way of an opening into the body (Eyes, nose, mouth) can contract the flu.

Non communicable diseases, such as cancer, are not contagious and are therefor not passed from person to person. Communicable diseases such as TB or AIDS can be passed around from person to person. So of course, that would be the reason for the spreading.
