5 Questions
Which of the following is a characteristic of the primary stage of FIV infection?
Virus can be detected in saliva within 3 weeks of infection
What is the asymptomatic stage of FIV?
A stage where immune dysfunction begins early
What happens to T-helper cells during the asymptomatic stage of FIV?
They decline progressively in number
What is the second-stage of FIV characterized by?
Profound lymphoid depletion and escape of virus from immunological control
Why is the term "feline AIDS" not preferred?
Criteria to define AIDS in cats are not determined
Study Notes
- FIV has a primary stage lasting 6-8 weeks with rapid virus replication.
- The virus can be detected in saliva within 3 weeks of infection.
- Immune response comprising CD8+ and antibodies can be detected from 2-6 weeks.
- Clinical signs such as fever, neutropenia, and lymphadenopathy are rare in natural exposure.
- Asymptomatic stage lasts for years and immune dysfunction begins early.
- Mild or intermittent clinical signs can be seen during the asymptomatic stage.
- Lymphocytes (T-helper cells) decline progressively in number during the asymptomatic stage.
- Immune hyperactivation and suppression contribute to overall immune dysfunction in FIV infection.
- Second-stage FIV is characterized by profound lymphoid depletion, escape of virus from immunological control, and terminal disease.
- The term "feline AIDS" is not preferred as criteria to define AIDS in cats are not determined.
