Abstract
Paediatric HIV infection continues to pose a serious threat in the developing world. While in the developed world, mother to child transmission has been reduced to less than 3%, in India no regular zidovudine (azidothymidine) intervention programmes operate. Some 20 million babies are born each year and the number of infected babies could be >50,000 per year. The present study was designed to assess the change, if any, in the time trends of HIV infection in children over the last 15 years as observed at the surveillance centre attached to Nehru Hospital, Chandigarh. All patients reporting to the surveillance centre at the PGIME&R, Chandigarh were subjected to a detailed history and screened for HIV by the three tests protocol recommended by the WHO. In babies under 18 months of age, viral load assay or DNA analysis was done to confirm infection. Timetrends were ascertained over a 15-year period to assess the impact of information, education and communication programme launched by National AIDS Control Organisation. Data indicates that the total number of HIV positive cases increased 10-fold over the last 10 years. During 1991, 41 cases were recorded; the number increased to 439 in year 2001, and 574 in 2004 (r=0.98). A similar trend was observed in the paediatric age group. During the initial 5 years ie, 1987 to 1992 only 7 paediatric cases were documented positive while the number increased to 45 in the year 2001 to 64 in the year 2004 with a cumulative figure of 323 children. Linear regression analysis showed a highly significant trend (r=0.94). Out of the 323 cases, 44.6% were symptomatic. Maximum number of babies were observed in the age group of 3-5 years. Thirty-nine patients (12%) had acquired the infection through blood. Thus the information, education and communication programme has had very little impact on the HIV epidemic and it calls for urgent antiretroviral intervention in antenatal mothers to control the emerging paediatric HIV epidemic.
