A woman who had traveled to Spain became the first confirmed case of covid with variant Delta, the mutation of the virus which raises concerns about its contagiousness. By virtue of its characteristics, it falls within the expected epidemiological criteria, since it is an imported case. In this sense, the predominant strain is another: the Manaus variant of the virus is the one that prevails, since 7 infected out of 10 are carriers. When examining what happened, other data also emerges, such as the minimum level of genomic analysis that is carried out in the provinces to detect circulating variants.
To the government they assure that the situation is under control, because for the moment there are no signs of additional infections. And they recognize that there is only one solution: vaccinate. This is where the shortcomings of the official program flourish, because although there are over a million people vaccinated in Mendoza and 27 million nationwide, the number of people vaccinated with the full regimen is still low. Variant Delta requires both doses to strengthen defenses.
Some samples
The pandemic detection and monitoring system is lacking. In Argentina, genomic analyzes are only carried out in Buenos Aires to determine variants of the virus. And there is no availability to conduct studies with samples. Only thisyou are confirmed travelers.
To get an idea, until the middle of the month they had only actually been analyzede 101 samples from Mendoza. “In our province, until 08/21/21, 157 samples were sent via SNVS to the Malbrán Institute and to the Country Project for genotype: There are 33 pending results, 17 were not suitable for sequencing and 6 were found to have no variant of interest ”, indicates the latest report from the Ministry of Health.
There it was shown that the predominant variant is that of Manau. “Of the 101 samples in which variants were detected in 72%, a Gamma variant (P.1) was identified and in 16% the Alpha variant (B 1.1.7)”, they specified. “There are 12% other variants: Iota (B1.516), Zeta (P.2) and Lambda (C37),” the report adds. At that time, no one with the Delta variant had been detected. Now there are some and we know it almost 20 days after the woman entered Argentina.
The infected woman arrived in Mendoza on August 3 from Spain. At the airport of Ezeiza They subjected her and her family to rigorous tests and tested negative. On the seventh day of isolation, they performed a PCR test and she was positive. The sample was sent to the Malbrán Institute and it was detected that it had the Delta variant. The result was known today and they decided to report it immediately, to avoid leaks.
