More people have died from non-Infectious Diseases, such as Heart disease, cancer, and Diabetes, primarily due to lifestyle factors like poor diet, lack of physical activity, and tobacco use. Additionally, the aging population has increased the prevalence of these chronic conditions, as they are often associated with older age. Advances in medical technology have also improved the management of infectious diseases, leading to lower mortality rates from those causes. Consequently, non-infectious diseases have become the leading cause of death globally.
The similarities in how children and older people contract and react to infectious diseases is that they catch them very easily. However older people have had more diseases so they can fight off a wider variety.
Infectious diseases spread faster in cities due to higher population density, which allows the pathogens to move more easily between people. Additionally, cities often have more frequent and diverse social interactions, increasing the chance of transmission. Limited access to healthcare services in some urban areas can also contribute to the spread of infectious diseases.
Infectious diseases are typically not passed on genetically, but some individuals may inherit genetic factors that make them more susceptible to certain infections. However, the immune system plays a significant role in fighting infectious diseases, and genetic variations can influence an individual's immune response to infections.
most people died from it so it does not spread any more
The cause was infectious diseases.

Communicable diseases are those that are spread by contact with other people or items that have touched their bodies. The other terms associated with this term are contagious and infectious which specify more clearly which type of contact is required for transmission.
No. Some diseases are not infectious. Even with ones that are, a person is not definitely going to get it by being in contact. Different diseases have more or less chances of infecting someone else and there are various ways a disease can be transmitted.
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.
The two factors that made diseases from Europe more severe than diseases from the Americas were the Europeans' long history of exposure to infectious diseases and their close proximity to domesticated animals, which increased the likelihood of disease transmission.
