C
Common illnesses rarely share symptoms with biological agents
D

Verified step by step guidance1
Understand that many biological agents used in attacks cause symptoms that are common to a variety of illnesses, such as fever, fatigue, and muscle aches.
Recognize that these nonspecific symptoms overlap significantly with symptoms of common infections like the flu or common cold, making initial diagnosis challenging.
Consider that early symptoms do not usually include unique or pathognomonic signs that would immediately indicate a biological attack.
Note that because these symptoms are common and mild at first, healthcare providers may not immediately suspect a biological attack without additional epidemiological or laboratory evidence.
Conclude that the difficulty in distinguishing early symptoms arises from the nonspecific nature of the symptoms caused by many biological agents, which resemble those of common illnesses.
