Annals of Internal Medicine
|December 1, 1985
Summary
Primary infection with Human T-lymphotropic virus type III (HTLV-III) presents with flu-like symptoms and rash. Early diagnosis is crucial for patients at risk of acquired immunodeficiency syndrome.
Area of Science:
- Virology
- Immunology
- Infectious Diseases
Background:
- Human T-lymphotropic virus type III (HTLV-III) is a significant human pathogen.
- Understanding primary infection is key to managing viral spread and disease progression.
Observation:
- Three patients exhibited documented primary HTLV-III infection via virus isolation and seroconversion.
- Acute illness symptoms included fever, rigors, arthralgias, myalgias, rash, urticaria, abdominal cramps, and diarrhea.
- Two patients developed lymphocytic meningitis during the febrile illness.
Findings:
- The incubation period for primary HTLV-III infection was estimated at 4 to 6 weeks.
- Symptoms persisted for 2 to 3 weeks.
- Seroconversion, marked by a specific antibody pattern, occurred 8 to 12 weeks post-exposure.
Implications:
- Clinicians should consider primary HTLV-III infection in individuals at risk for acquired immunodeficiency syndrome presenting with prolonged febrile illnesses.
- Early recognition aids in timely intervention and patient management.
- This study highlights the clinical manifestations of early-stage HTLV-III infection.

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
