A.30 is basically dead, well outcompeted by Delta etc. The UK don't report on it now.
"VUI-21FEB-01 (A.23.1 with E484K), VOC-21FEB-02 (B.1.1.7 with E484K), VUI-21MAR-01, (B.1.324.1 with E484K), A.30, B.1.633, B.1.214.2 and B.1.1.7 with S494P have not been observed in the UK or within the international GISAID dataset within the last 12 weeks. These variants are no longer included in the data update."
One of the best (IMHO) Sci-Fi books "His Master's Voice" by Stanisław Lem begins exactly like this.
"It is a densely philosophical first contact story about an effort by scientists to decode, translate, and understand an extraterrestrial transmission. The novel critically approaches humanity's intelligence and intentions in deciphering and truly comprehending a message from outer space."
