Final answer:
Emerging and re-emerging infectious diseases can disrupt trade, tourism, and economic activities, leading to economic losses. The COVID-19 pandemic is an example of how these diseases can impact the global economy.
Step-by-step explanation:
Emerging and re-emerging infectious diseases can have significant effects on the global economy. These diseases can disrupt trade, tourism, and other economic activities, leading to economic losses. For example, during the COVID-19 pandemic, many countries implemented lockdowns and travel restrictions, which resulted in a decline in international trade and tourism. The supply chains were disrupted, causing shortages of essential goods and increasing their prices. Additionally, healthcare costs and productivity losses associated with treating and managing infectious diseases can also impact the economy.
