HIV infection in Zimbabwe

Area of Science:

• Pediatrics
• Infectious Diseases
• Public Health

Background:

• Human Immunodeficiency Virus (HIV) infection poses a significant global health challenge, particularly in pediatric populations.
• Early identification and management of pediatric HIV are crucial for improving outcomes and preventing transmission.
• Understanding the clinical presentation and epidemiological trends of pediatric HIV is essential for targeted interventions.

Purpose of the Study:

• To determine the incidence and clinical characteristics of Human Immunodeficiency Virus (HIV) infection in a cohort of children.
• To identify common presenting symptoms and risk factors associated with pediatric HIV.
• To report on the mortality rates and outcomes in children diagnosed with HIV.

Main Methods:

• Retrospective analysis of pediatric cases with positive serology for HIV over an 18-month period.
• Clinical data collection including presenting features, asymptomatic status, and maternal HIV status.
• Follow-up data on patient outcomes, including mortality.

Main Results:

• A total of 188 children tested positive for HIV during the study period.
• The most frequent clinical manifestations were generalized lymphadenopathy, failure to thrive, chronic diarrhea, and pneumonia.
• Two HIV-seronegative children with Acquired Immunodeficiency Syndrome (AIDS) had HIV-seropositive mothers, highlighting potential diagnostic challenges.
• Ten children were initially asymptomatic, with one later succumbing to infection.
• A significant mortality rate was observed, with 34 children known to have died.

Conclusions:

• Pediatric HIV infection presents with diverse clinical features, necessitating high clinical suspicion.
• Prompt diagnosis and intervention are critical, as even asymptomatic children can progress to severe disease.
• The study underscores the importance of maternal HIV screening and early diagnosis in infants born to HIV-positive mothers to reduce pediatric HIV burden.
