Notes for a correct interpretation
• Sampling may not be uniform within the different
autonomous communities. Therefore, it is important not
to assume that the counts/frequencies shown are
necessarily representative of the region.
• The charts used are based on the sample collection date,
and sequencing or GISAID submission date. As a result,
this date may differ from when the sample was processed
and sequenced, and when the data is released to the public.
• In relation with the last consideration, last data
pints often has incomplete data and may change as more
sequences come in.
• The mutations that define SARS-CoV-2 (CoV-19) lineages
are updated every few days. Therefore, displayed data is
susceptible to change over time.
We are grateful to the data contributors who shared the
data used in this Web Application via the GISAID
Initia-tive*: the Authors, the Originating Laboratories
responsible for obtaining the specimens, and the Submitting
Laboratories that generated the genetic sequences and metadata.
