Incorrect measurement. In the article “Management of Infants Born to Mothers with HIV Infection,” (July 2021, p. 58) the HIV RNA load threshold for recommending a cesarean delivery was incorrect in the second sentence of the Perinatal Transmission section on page 58. The sentence should have read “Strategies to prevent mother-to-child transmission include giving antiretroviral therapy (ART) to mothers with HIV infection and their infants, scheduling cesarean deliveries for women with an HIV RNA load greater than 1,000 copies per mL or an unknown viral load at the time of delivery, and providing formula instead of breast milk to infants of mothers living with HIV.” The online version of this article has been corrected.
