Discuss the impact of diseases, and whether they are increasing or decreasing
Diseases are numerous and diverse in terms of how they occur.
disease, tuberculosis, malaria, cancer, etc. can all be considered diseases.
know how to answer the “increasing or decreasing” question, but I would imagine

than it is in other developing countries.
