the Argentine SARS-CoV-2 Inter-Institutional Genomics Project (PAIS), announced that more than 95% of coronaviruses circulating in AMBA correspond to virus variants of the original Wuhan coronavirus. These are mainly those detected in the United Kingdom, Manaus, Peru and California. In addition, you are in several provinces, such as Cordoba, Santa Fe and Mendoza.
Currently, there are more than 1,500 lineages of the virus. However, the World Health Organization (WHO) I determine four as “of concern“Already seven”of interest”.
The first are called “alfa“, Detected in UK,”beta“Who comes from South Africa”,gamma“From Manaus and”delta“From India.
Those that interest us are the “epsilon” and “iota” the United States, “zeta” from Brazil, “and“It has been detected in several countries. “theta“From the Philippines,”kappa“Also from India and”lambda“From Peru.
According to a report by the PAIS consortium, the delta and the beta They were only observed in Argentina in two travelers who were isolated. The first came from Paris and the second from Spain.
Today, the most worrying is the delta, which has already been detected in more than 80 countries and whose incidence is doubling in less than two weeks. In fact, 90% of cases in the UK lately fit this variant and it has forced Prime Minister Boris Johnson to extend the restrictions for another four weeks.
Molecular virologist at INTA and member of the PAIS consortium, Humberto Dibat, he assured that after this detection in the traveler “it did not appear any more in the studies of genomic follow-up, neither in the international system of test of income nor in the random sampling at the federal level; in other words, there is still no proof that it is circulating in the community ”.
But at the same time, he added that “with the antecedent of our systematic failure to prevent international entry and the establishment of the different variants, starting with that of Rio (Zeta), that of the United Kingdom ( Alfa), that of Manaus (Gamma) and California (Epsilon), our expectations of being able to prevent him from settling in the country should be low and we must act on the assumption that it will eventually enter and that it can boost our epidemiological situation. ”
This is why a group of researchers asked health authorities to extreme checks and tests on travelers, including a five-day lockdown.
Today it was determined that a passenger who arrived in the country on June 4 was infected with the delta strain. Although he had a negative PCR performed 48 hours before the trip, the test on arrival showed the antigen positive.
The other variant that worries researchers is the C.37, also called “Andean”. It is widespread in Peru and is found in Chile and our country, accounting for more than 30% of the samples analyzed.
