3 de may. de 2024 · To identify variants, scientists map the genetic material of viruses (known as sequencing) and then look for differences between them to see if they have changed. Since 2020, SARS-CoV-2, the virus that causes COVID-19, has been spreading and changing globally.
27 de mar. de 2024 · From May 2021 onwards, WHO began assigning simple, easy-to-say labels for key variants. Considerable progress has been made in establishing and strengthening a global system to detect signals of potential VOIs or VOCs and rapidly assess the risk posed by SARS-CoV-2 variants to public health.
Se requiere una combinación de ciencia de laboratorio, estudio de manifestaciones clínicas e investigaciones epidemiológicas detalladas para caracterizar con precisión y rapidez los riesgos para la salud pública de las variantes del SARS-CoV-2.
El presente documento tiene por objeto describir un conjunto mínimo de actividades de vigilancia recomendadas a nivel nacional para detectar y monitorear la prevalencia relativa de las variantes del SARS-CoV-2 y describir a grandes rasgos un conjunto de actividades para caracterizar y evaluar el riesgo que estas suponen.
28 de mar. de 2022 · Genomic surveillance has shaped our understanding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants. We performed a global landscape analysis on SARS-CoV-2...
