Answer:
<u>HIV infection</u> cannot be diagnosed within some weeks or months the HIV enters the body
Explanation:
Once a person acquires HIV, there is a period of time —weeks or months— before the antibodies can be detected, which is called the window period.
Human Immunodeficiency Virus (HIV) infection is acquired through contact of body fluids or blood from a carrier with a healthy person. The disease that develops from HIV is called acquired immunodeficiency syndrome (AIDS), which involves a failure of the body's immunity and makes it susceptible to infectious disease or cancer.
The relative absence of symptoms and undetected antibodies means that the first few weeks of HIV infection cannot be seen.

Epidemiologists also attempt to determine what factors are associated with diseases (risk factors), and what factors may protect people or animals against disease (protective factors).
