Step 1
Effect 1: Controlling the Spread of Disease
Answer
The widespread use of antibiotics can effectively control the spread of bacterial diseases. By administering these drugs to infected individuals, the growth of bacteria is inhibited, leading to recovery and a lower chance of spreading the infection to others. This can result in a decline in disease prevalence within communities, allowing for better public health outcomes.
Step 2
Effect 2: Development of Multi-Resistant Bacteria
Answer
On the contrary, the overuse of antibiotics can lead to the development of multi-resistant bacteria, often referred to as 'superbugs.' These bacteria evolve in response to antibiotic pressure, rendering common treatments ineffective. As multi-resistant strains proliferate, they pose significant health risks, potentially leading to outbreaks of infections that are difficult to treat and control, thereby escalating the spread of diseases in the future.
