Para alguien de acá, esto significa que esperar a ver si mejora puede costar caro, sobre todo en los grupos de riesgo. Muchas veces el problema no es el acceso al sistema sino la demora en decidir pedir ayuda. Un límite del estudio es que se hizo en una sola unidad y con datos retrospectivos, así que no se puede generalizar a todo el país.","quienFirma":"Instituto Mexicano del Seguro Social (IMSS)","confianza":"preprint","consulta":null},"sello":{"hash":"d9b1266fa0d56bc175bcf84e840b5ea9c19d1e9c0a5642228ee6cee9ce666fb7","sello":"17f82b59fad41cbe690fe549e7884c643c7ea38374e409c23f047284e18cc82e","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6635785,"aleatorio":"d4d3b4fce165d59785935f5cbd3c0fd114154106c582aa8aa329481a3a15c19e","tiempo":"2026-11-12T17:29:30.000Z"},"nist":{"cadena":2,"pulso":2024826,"salida":"72723DFCBF5D406B1C315B8198A68058C7B5F4AC2E50CDBB5D36725932697C27CA728C78B930C44BD5FE18409BDA1D90DC0725A078F0EAC07D2A880E32256142","tiempo":"2026-11-12T17:28:00.000Z"},"noAntes":"2026-11-12T17:29:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Nov 12 17:29:49 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Delayed first contact in a universally insured population: time to care and COVID-19 outcomes in Mexican primary care","descripcion":"Time from symptom onset to first care may be a modifiable determinant of COVID-19 outcomes, but it is rarely quantified in primary care.
