“…The positivity of SARS-CoV-2 in Yucatan during the first wave of the COVID-19 pandemic was around 0.1 to 0.58 in symptomatic individuals, it remained similar during the months of May and June (7). However, during high transmission scenarios, the pooling strategy should not replace individual testing and the pool size should be choose relative to the prevalence (8).…”

Introducción. Los sistemas de salud públicos y privados a nivel mundial han padecido numerosas dificultades durante la actual pandemia de COVID-19. Altos números de portadores asintomáticos han dificultado la vigilancia y el seguimiento de los individuos infectados. Así mismo, los laboratorios de diagnóstico han sufrido con deficiencias en reactivos para realizar el diagnóstico. Realizar agrupaciones de muestras clínicas es una alternativa para sobrellevar la poca disponibilidad de reactivos y el diagnóstico de individuos asintomáticos. Métodos. Se realizó la agrupación de 1937 muestras clínicas de personas asintomáticas que realizaban actividades esenciales durante la primera ola de COVID-19 en Yucatán, México. Se realizó diagnóstico por RT-PCR en tiempo real utilizando el método Berlin en 229 agrupaciones de muestras. Resultados. La estrategia detectó de manera exitosa casos positivos de personas asintomáticas con COVID-19. Un total de 27 agrupaciones fueron positivas. Los individuos positivos realizaban actividades esenciales en la administración del gobierno del estado, en supermercados o en la fuerza policiaca. Conclusión. La agrupación de muestras clínicas es una estrategia para facilitar el aislamiento oportuno de individuos infectados asintomáticos, así como para ahorrar en reactivos de laboratorio.

“…However, as the epidemic evolves, countries and regions may make policy adjustments. Studying the policy combination of non-pharmaceutical interventions at different points in time in various countries and regions can effectively help governments make policies to control the epidemic spread [41,42]. Future studies could the time-series changes in epidemic policies based on a dynamic perspective.…”

The global outbreak of COVID-19 has been wreaking havoc on all aspects of human societies. In addition to pharmaceutical interventions, non-pharmaceutical intervention policies have been proven to be crucial in slowing down the spread of the virus and reducing the impact of the outbreak on economic development, daily life, and social stability. However, no studies have focused on which non-pharmaceutical intervention policies are more effective; this is the focus of our study. We used data samples from 102 countries and regions around the world and selected seven categories of related policies, including work and school suspensions, assembly restrictions, movement restrictions, home isolation, international population movement restrictions, income subsidies, and testing and screening as the condition variables. A susceptible-exposed-infected-quarantined-recovered (SEIQR) model considering non-pharmaceutical intervention policies and latency with infectiousness was constructed to calculate the epidemic transmission rate as the outcome variable, and a fuzzy set qualitative comparative analysis (fsQCA) method was applied to explore the multiple concurrent causal relationships and multiple governance paths of non-pharmaceutical intervention policies for epidemics from the configuration perspective. We found a total of four non-pharmaceutical intervention policy pathways. Among them, L1 was highly suppressive, L2 was moderately suppressive, and L3 was externally suppressive. The results also showed that individual non-pharmaceutical intervention policy could not effectively suppress the spread of the pandemic. Moreover, three specific non-pharmaceutical intervention policies, including work stoppage and school closure, testing and screening, and economic subsidies, had a universal effect in the policies grouping for effective control of the pandemic transmission.
