Search the frequency of a variant or a group of variants (haplotype) in the GISAID database. The search will yield the population frequency of all the genomes containing the variant(s). Only substitutions coded as e.g. "C241T" are allowed. In the results section, CovidPhy will also provide the frequency of the variant(s) along the time since the beginning of the pandemic.

Some samples of interest:
