Si el tratamiento actual cambió ese panorama, muchas familias pueden tener menos miedos innecesarios y los equipos de salud pueden enfocarse en lo que sí hace falta. El resultado vale para contextos con tratamiento generalizado como el del estudio, en una sola ciudad.","quienFirma":"Universidad de Nairobi, Kenia","confianza":"preprint","consulta":null},"sello":{"hash":"9f58af82cd12526099a7e0593049c419439e8f4101ff36c1eaeefb6169393894","sello":"8f9487323faf34037905d6674d8ea5e9405c2d611e456d65cd5951666e28fe4d","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6596219,"aleatorio":"d7607553a52033d91a72c90ee750a3a506f07cd72d1c29249334c16fad15c4ec","tiempo":"2026-10-29T23:46:30.000Z"},"nist":{"cadena":2,"pulso":2005043,"salida":"2DA44EF607F4EAF5C58160E82A595D10AD36CF1B3B55F6509A1B95B5EF1CD1690FB74F1F5980488256CB2ED5BD60A1EC62CA16516061E7C875D4E8C41361740B","tiempo":"2026-10-29T23:45:00.000Z"},"noAntes":"2026-10-29T23:46:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 29 23:46:52 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Postnatal CMV acquisition risk is not increased among children who are HIV-exposed, uninfected versus HIV-unexposed in the setting of optimized maternal ART","descripcion":"Historically, children who are HIV-exposed, uninfected (CHEU) had higher incidence and earlier postnatal acquisition of cytomegalovirus (CMV) than children who are HIV-unexposed. We assessed whether this difference persists in the current era of universal antiretroviral therapy (ART).
