In which way has the study of biology helped us to control infectious diseases?

Various advancements that have occurred in the field of biology have helped us gain a better understanding to fight against various infectious diseases. Biology has helped us study the life cycle of various parasites, pathogens, and vectors along with the modes of transmission of various diseases and the measures for controlling them. Vaccination programmes against several infectious diseases such as small pox, chicken pox, tuberculosis, etc. have helped eradicate these diseases. Biotechnology has helped in the preparation of newer and safer drugs and vaccines. Antibiotics have also played an important role in treating infectious diseases.

• Helps to properly diagnose the problem and treat them
• Life cycle, host, reservoir, vectors, agents all can be studied and identified
• Mechanism of transmission of pathogens to humans are known
• Protective measures against catching the diseases are suggested.
•  Vaccines and medicines against pathogen are worked out.
