This retrospective cross\u2010sectional study was conducted at a tertiary pediatric oncology center in South India from January 2020 to August 2025. Children (\u2264\u200918 years) with ALL who developed CMV reactivation during chemotherapy were included. CMV testing was performed based on clinical indications, and viral load was quantified using multiplex polymerase chain reaction. Demographic, clinical, laboratory, treatment, and outcome data were analyzed. Of 150 children treated for ALL, 29 (19.3%) experienced CMV reactivation. The median age was 6 years, with a male predominance (72.4%). Reactivation occurred predominantly during consolidation (51.7%) and maintenance (41.4%) phases. Fever was the most common presentation (75.9%). The median CMV viral load was 1.48\u2009\u00d7\u200910\n                    <jats:sup>3<\/jats:sup>\n                    \u2009IU\/mL; 69% had viral loads &gt;\u20091\u2009\u00d7\u200910\n                    <jats:sup>3<\/jats:sup>\n                    \u2009IU\/mL.

The median time to CMV PCR negativity was 14 days, and peak viral load showed a strong positive correlation with time to PCR clearance (\n                    <jats:italic>\u03c1<\/jats:italic>\n                    \u2009=\u20090.697,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001). Antiviral therapy was administered to 79.3% of patients. At last follow\u2010up, 86.2% were alive, with no CMV\u2010attributable mortality. CMV reactivation during chemotherapy for pediatric ALL is frequent in high\u2010prevalence settings and is associated with lymphopenia and prolonged immunosuppression. A targeted, risk\u2010adapted strategy for CMV testing and treatment may be preferable to universal surveillance.\n
