Epidemiologists have identified the spread of influenza in 1918 and the rise of AIDS in the 1980s as examples of: (1 point) Responses global pandemics. global pandemics. blood-borne pathogens. blood-borne pathogens. increased transportation. increased transportation. sexually transmitted diseases.

Responses global pandemics.

The correct answer is global pandemics.

Epidemiologists have identified these two instances, the spread of influenza in 1918 and the rise of AIDS in the 1980s, as examples of global pandemics.

To arrive at this answer, we can break down the options provided:

1. Global pandemics: This option directly matches the prompt and describes the widespread occurrence of a disease affecting a large population across multiple countries or continents.

2. Blood-borne pathogens: While both influenza and AIDS can be transmitted through bodily fluids, the term "blood-borne pathogens" specifically refers to diseases spread through blood contact, such as HIV or hepatitis.

3. Increased transportation: While increased transportation can contribute to the spread of diseases, it does not specifically define the examples given.

4. Sexually transmitted diseases: While AIDS is primarily transmitted thual contact, the prompt also mentions the spread of influenza in 1918, which is not a sexually transmitted disease.

By process of elimination, we can conclude that "global pandemics" is the correct answer, as it encompasses the spread of both influenza in 1918 and AIDS in the 1980s.

The correct answer is: global pandemics.
