Perinatal HIV infections in Thailand.

A collaborative study group of researchers from seven hospitals from all regions of Thailand was formed to collect information on children born to HIV-infected mothers since the beginning of the first hospital case until the end of June 1994. The study conducted to verify the status of perinatal transmission of HIV infection in Thailand showed a rapid increase in HIV seropositivity among Thai mothers with vertical transmission rates varying between 25% in Rayong and 42% in Chiang Rai Hospitals, respectively. The majority of children with symptomatic HIV infection had clinical presentations of delayed growth development, pneumonia, diarrhea, oral candidiasis, lymphadenopathy, hepato-splenomegaly. Cases of Penicillium marneffei infection were found only at Chiang Rai Prachanukroh Hospital. The ages at which diagnosis of HIV disease was made were mostly within the first year of life. One third of children with AIDS died during the period of study.
