To gain insights into the the emergence, spread, and transmission of COVID-19 in our community, we are working with a large number of partners to sequence SARS-CoV-2 samples from patients in San Diego and across the border in Tijuana. In this preliminary analysis we look at the how the outbreaks are connected between California, USA and Baja California, Mexico.
Critically, while we can show that the outbreaks are connected, we are unable to establish directionality of virus spread and say whether the virus has primarily migrated North to South or South to North. We can see that the outbreaks are connected in San Diego and Tijuana, which indicates that the virus (via people) has moved – and continues to move – between these locations. However, we cannot determine more precisely how it moves between the two cities.

Para entender la emergencia, propagación y transmisión de COVID-19 en nuestra comunidad, estamos trabajando con un amplio grupo de colaboradores para secuenciar muestras de SARS-CoV-2 de pacientes en San Diego, California y del otro lado de la frontera en la ciudad de Tijuana, B.C (México). En este análisis preliminar observamos de qué manera se conectan los brotes de SARS-CoV-2 entre California, EE. UU., y Baja California, México.
Si bien pudimos demostrar que los brotes de SARS-CoV-2 entre San Diego y Tijuana están conectados, no pudimos establecer la direccionalidad de la propagación del virus y determinar si el virus ha migrado principalmente del Norte al Sur o del Sur al Norte de la frontera. Pudimos observar que los brotes están conectados en San Diego y Tijuana, lo que indica que el virus (por medio de las personas) se ha movido, y continúa moviéndose entre estas ciudades. Sin embargo, no podemos determinar con más precisión cómo se mueve entre las dos ciudades.
