Nine out of ten cases of coronavirus detected in Spain are of the delta variant, which continues its expansion throughout the territory, exceeding 90% in most communities, except the Canary Islands, Madrid, Castilla y León, Extremadura and La Rioja.
This is clear from the latest update of the epidemiological situation of the SARS-CoV-2 variants with the greatest impact and interest in public health in Spain, prepared by the Center for the Coordination of Health Alerts and Emergencies (CCAES) of the Ministry of Health.
The variant B.1.617.2 or delta, originated in India, maintains its upward trend in recent weeks and, with data from most of the communities until August 8, occupies 94.3% of the space to the detriment of others such as alpha, the most widespread at the beginning of the year but now barely represents between 0.06% and 0.3%.
In almost all of them it exceeds 90% of the cases and in some it is close to practically all, such as the Balearic Islands, which registered 99.8% in week 32 (until August 15), or Aragon (98.2% a week before ).
Cantabria also surpassed that figure (97.9%); Navarra (97%); Galicia (96.6%); Catalonia (94.5%): Valencian Community (94.2%); Andalusia (93.6%) and the Basque Country (92.1%).
Below are the Canary Islands (86.3%) and Extremadura (33.3%). Also Castilla y León (49.9%), although in this case it did not update its information from week 30 (July 26 to August 1), the same as Madrid, which by that date had 57.6% of cases probable delta variant. La Rioja, for its part, has not done so since week 26, when it was 8.2%.
In addition to delta and alpha, Health considers variants of concern for public health (VOC, for its acronym of interest) to be variants B.1.351 or beta, which appear in significant percentages in some communities mainly associated with outbreaks, and P .1 or gamma, which has been kept at very low levels.
The Ministry also monitors eight other variants of interest: B.1.427 / B.1.429 or epsilon; the P.2 or zeta; B.1.525 or eta; B.1.526 or iota; B.1.617.1 (kappa); C.37 (lambda); B.1.1.7 with E484K mutation and B.1.621.
