Final answer:
Caregivers losing time at work and individuals having difficulty working and earning income are reasons why infectious diseases like malaria and HIV/AIDS often hamper economic development.
Step-by-step explanation:
One of the reasons why infectious diseases like malaria and HIV/AIDS often hamper economic development is because caregivers lose time at work.
When individuals become sick with these diseases, their family members or friends often have to take time off from work to care for them.
This can result in decreased productivity and income, which can have a negative impact on economic development.
Another reason is that people have difficulty working and earning income when they are infected with these diseases.
Malaria and HIV/AIDS can cause severe illness and weaken the immune system, making it difficult for individuals to perform their job duties and earn a living.
While life expectancy may begin to rise in some cases due to advancements in healthcare and treatment, this is not a reason why infectious diseases hamper economic development.
Similarly, while more tax dollars may be shifted to healthcare to address the burden of these diseases, it is not a reason why economic development is hampered.
