Slower population growth wasnot a reason why communicable diseases, such as pneumonia, killed fewer people today than they did in the past.

Further Explanation:

If an individual’s immune system is weak then bacteria can easily spread into the lungs. They can infect lung to a great extent and can cause inflammation. This condition can become too lethal. A person undergoing a recent organ transplantation is more under risk of communicable disease. The main reason behind the diffusion of Pneumonia is its contagious nature as it bacteria have the capacity to multiply itself. Pollution in recent times is another important reason behind the spreading of these diseases. The condition was not the same in the past as there was not much pollution and people's immunity was also much stronger than in modern times. So we can’t say that slower population growth was the reason behind the less death due to communicable diseases.
