Disease is a part of human existence, and most of our history has been dedicated to understanding health problems to better our lives. In fact, studying diseases is an aspect of human struggle that has always been essential to our survival.
This course will tackle an essential element of human disease: infectious diseases.
Despite the emphasis on sterilization and antiseptic measures worldwide, infectious diseases are ranked as one of the primary causes of mortality and morbidity in the developing world to date, particularly among young children.
In 2019, the WHO recognized lower respiratory tract infections (LRTIs) and diarrheal diseases as the top ten leading causes of mortality worldwide. Also, with the emergence of COVID-19, infectious diseases became a major health concern globally, affecting both developed and underdeveloped countries alike.
A survey carried out by the Centers for Disease Control and Prevention (CDC) ranked COVID-19 as the third leading cause of mortality in the U.S., only behind cardiovascular disease and cancer.
This course aims to provide a concise review of the infectious diseases causing major health concerns globally, their causative organisms, modes of transmission, symptomatology and clinical picture, treatment, as well as the preventive measures devised for their control.
We will first look at infectious diseases and the mechanisms by which they are governed — understanding the nature, etiology, and ecology of infectious diseases.
Understanding the types of diseases, their causes, and mechanisms, we will also look at the different modes of disease transmission, their impact on our lives, and prevention.
When dealing with a disease, we can often only adopt a pathological lens and not pay attention to the control and prevention aspect of it. So, the main objective of this course is to equip its readers with an accurate source of clinically relevant information that is appropriate at their level. It also teaches students to inculcate the techniques of sterilization and antisepsis in their day-to-day routine, thereby reducing the incidence and transmission of communicable diseases at a community level and, essentially, at a global scale.
