*Van Doremalen N, et al. Aerosol and Surface Stability of SARS-CoV-2 as Compared with SARS-CoV-1 [texto completo]. N Engl J Med. 2020;10.1056/NEJMc2004973 [doi]. nejmRESUMEN: Trabajo experimental que valora la estabilidad del SARS-Cov-2 en aerosol y varios tipos de superficies (plástico, acero inoxidable, cobre y cartulina), comparándolo con el SARS-CoV-1 y estimando las tasas de desintegración mediante un modelo de regresión Bayesiana. El SARS-Cov-2 permaneció viable en aerosol durante todo el tiempo que duró el experimento (3h), con una reducción de la titulación de virus (TCID 50 entre 10 3.5 – 10 2.7 por litro de aire). La semivida del SARS-Cov-2 fue de 1.1-1.2h (IC95% 0.64-2.64). Los resultados del experimento para SARS-Cov-1 fueron similares. El SARS-Cov-2 permaneció más estable en plástico y en acero inoxidable, detectando virus viable hasta 72h tras la aplicación en estas superficies. No se detectó virus viable en cobre a partir de 4h y en cartulina a partir de 24h. Las semividas del SARS-Cov-2 fueron 5.6h en acero inoxidable y 6.8h en plástico. No hubo diferencias sustanciales con respecto a las semividas de SARS-Cov-1 en acero, plástico y cobre. En cartulina la semivida del SARS-Cov-2 fue superior, pero los investigadores explican que tuvieron elevada variabilidad en los experimentos y que esta diferencia con respecto al SARS-Cov-1 debe interpretarse con cautela. Los resultados de los investigadores sugieren que la transmisión a través de aerosoles y fomites es plausible por la gran estabilidad del virus en aerosol (horas) y superficies (días), dependiendo del inóculo. Dado que no encontraron diferencias sustanciales en la estabilidad de ambos tipos de coronavirus en las diferentes condiciones experimentales evaluadas, sugieren que las diferencias epidemiológicas de ambas infecciones deben estar causadas por otros factores, por ejemplo la elevada carga viral en vía respiratoria superior y la capacidad de transmisión de las personas asintomáticas.

Lancet. 2020;395(10226):809–15 [doi]. RESUMEN: Se lancettrata de un estudio retrospectivo para evaluar las características clínicas de COVID-19 en el embarazo y la potencial de transmisión vertical intrauterina de la infección por COVID-19. Se revisaron los datos de 9 mujeres embarazadas que ingresaron en el Hospital Zhongnan de la Universidad de Wuhan (China) del 20 al 31 de enero de 2020 con infección por COVID-19. Todas las pacientes fueron diagnosticadas de infección por COVID-19 durante el 31 trimestre. Siete pacientes presentaron fiebre,  4 tos, 3 mialgias, 2 dolor de garganta y 2 malestar (en 2). Cinco pacientes tuvieron linfopenia (<10  células/L), seis presentaron elevación de PCR (>10 mg/L) y tres alteración de ALT y AST. Ocho presentaron infiltrados parcheados en vidrio deslustrado en el CT de tórax. Todas las pacientes precisaron oxigenoterapia en gafas nasales y antibioterapia empírica y 6 recibieron tratamiento antivírico. A 4 de febrero del 2020 ninguna de las pacientes había desarrollado neumonía grave por COVID-19 ni había fallecido. Ninguna paciente presentaba comorbilidad, una de ella tenía HTA gestacional desde la semana 27 y la otra preclampsia desde la semana 31. Las nueve fueron sometidas a una cesárea pero ninguna directamente en relación con la infección por COVID-19. Tras el inicio de la infección se detectó sufrimiento fetal en dos casos y rotura prematura de membranas en otro. Se registraron nueve nacimientos vivos. Los nueve nacidos vivos tuvieron una puntuación de Apgar de 1 minuto de 8 a 9 y una puntuación de Apgar de 5 minutos de 9 a 10. Todos nacieron después de la semana 36 con dos de los 4 prematuros con pesos por debajo de 2500 g. Se analizaron las muestras de líquido amniótico, sangre del cordón umbilical, hisopo neonatal de la garganta y leche materna de seis pacientes para detectar el SARS-CoV-2, y todas las muestras resultaron negativas para el virus por lo que no existe evidencia de infección intrauterina causada por transmisión vertical en mujeres que desarrollan neumonía por COVID-19 al final del embarazo.
