The Ministry of Health of the Nation reported this Thursday January 27 that, In the last 24 hours, 77,729 new coronavirus infections and 334 deaths were registered, the highest figure in more than five months. The last time a higher number was recorded was on August 9, 2021, with 502 deaths. Argentina had exceeded 120,000 fatalities yesterday and reached 120,352 deaths. The infections, meanwhile, add up 8.207.752.
From yesterday to today they were made 131,582 tests. As a result, the recorded positivity rate is 59,07%. That is to say: almost 6 out of 10 who were tested tested positive for coronavirus.
On the other hand, of the total deaths reported today, 174 are men and 157 women. The province of Buenos Aires was the one that notified the most deaths, with 109 deceased. It was followed by Chaco with 43, Córdoba with 39 and Salta with 35. Three deceased people (one resident in the province of Córdoba, another in Salta and another resident in the province of Tucumán) were reported without data on sex.
According to the epidemiological part, at the moment, in Argentina there are 2,836 people with coronavirus hospitalized in intensive care. They are 196 more than yesterday. The percentage of bed occupancy at the national level is 49.7% and in the Metropolitan Area of Buenos Aires (AMBA) it is 48.1%.
Of the 77,729 infections reported today, more than half are concentrated in PBA (34,862 cases), CABA (8,592) and Córdoba (7,643). Between the three jurisdictions they accumulated 51,097 cases, a figure that represents 65.7% of the total.
For the rest of the country, the numbers were as follows: Catamarca 654 infections, Chaco 1,584, Chubut 951, Corrientes 475, Entre Ríos 1,610, Formosa 1,614, Jujuy 1,422, La Pampa 973, La Rioja 379, Mendoza 2,091, Misiones 372, Neuquén 1,119, Río Negro 914, Salta 885, San Juan 1,362, San Luis 1,027, Santa Cruz 425, Santa Fe 5,725, Santiago del Estero 360, Tierra del Fuego 349 and Tucumán 2,341.
The Omicron variant of the coronavirus spread in Argentina much faster than the previous variant of concern, Delta. As revealed by a group of researchers who carry out genomic surveillance of the coronavirus at the ANLIS/Malbrán Institute, dependent on the National Ministry of Health, Ómicron was detected in the first days of last December in samples analyzed from patients with COVID-19 who had been abroad. Over the next two weeks, Omicron became the predominant variant, while the Delta variant took more than 10 weeks last year to be detected in more than 50% of samples in 2021.
According to the latest report from the ANLIS/Mabrán Institute, the Ómicron variant is already in all regions of the country and has been predominant for two weeks after it was detected in December. In the week of January 2 last the proportion of the Omicron variant in cases without travel history was 84.4%, while the proportion of the Delta variant decreased to 15.6%, among the samples analyzed by genomic sequencing and rt-PCR.
Regarding the samples analyzed for the detection of characteristic mutations of SARS-CoV-2 by rt-PCR (screening) it was observed that in the last week of December 2021 the proportion of samples compatible with the Omicron variant was between 55.5% and 94.7%, according to the report of the ANLIS/Malbrán Institute.
“A general decrease in Delta variant detection was observed in most provinces compared to previous weeks,” the scientists reported. “The circulation of SARS-CoV-2 variants is currently characterized by a rapid growth of the Omicron variant with a concomitant decrease in the detection of the Delta variant in several of the country’s jurisdictions,” he added.
“It was a very big difference compared to the previous stage. When we analyzed the Delta variant of the coronavirus last year, its growth was slow for several months. Instead, Omicron took everything. Its spread was not staggered like that of the previous variant,” he told Infobae Dr. Josefina Campos, scientist in charge of research at ANLIS/Malbrán. “The coronavirus surprises us every day,” he stressed.
