1. Describe the initial symptoms associated with Rocky Mountain spotted fever.
Severe abdominal pain and diarrhea.
An early measles-like rash and fever.
Joint pain and swelling.
Persistent cough and chest pain.
2. If a patient presents with symptoms common to both influenza and COVID-19,
how would comparing these diseases assist in their diagnosis?
It would help identify specific symptoms and transmission
patterns that distinguish one disease from the other.
It would indicate that the patient has a different unrelated disease.
It would eliminate the need for further testing.
It would suggest that both diseases require the same treatment.

Sepsis
Rheumatic fever and glomerulonephritis
Angina
Pnemuonia
6. If a patient presents with fever, sore throat, and headache, what steps should a
healthcare provider take to assess for measles?
Conduct a thorough patient history and physical examination, and

13. If a new infectious disease primarily affects the respiratory system, what
implications does this have for public health strategies?
Public health strategies should focus on respiratory transmission
prevention and vaccination efforts.
Public health strategies should concentrate on improving skin health
and hygiene.
Public health strategies should emphasize mental health support and
counseling.
Public health strategies should prioritize dietary changes and exercise
programs.
14. What is one key benefit of comparing similar infectious diseases?
It aids in accurate diagnosis.
It eliminates the need for treatment.
It simplifies the study of unrelated diseases.
It guarantees a cure for all diseases.
15. Scarlet fever, rheumatic fever, and glomerulonephritis are possible
complications associated with ...
