On December 5, the Ministry of Health confirmed the first case of Omicron on the Argentina. It’s a traveler 38 years old, resident of the province of saint Louis, who attended a work event in South Africa and who came back to the country on November 30.

Later, he went home in a rental car, with a driver.

Since his arrival in San Luis, the affected person remained in isolation and the December 2nd was notified that people with whom you shared the event were diagnosed as positiveTherefore, the diagnostic tests were carried out again, both with positive results.

Both the affected and four narrow contacts of this are in isolation, all asymptomatic. “He has no symptoms, not even a headache. He went to be tested because his colleagues who were in South Africa informed him that they were positive for coronavirus, “said the Minister of Health of San Luis, Silvia Sosa Araujo.

Why is Ómicron called like this?

Since the WHO defined the use of the letters of the Greek alphabet to name the variants of Covid-19 to avoid prejudice and discrimination, 13 names were available for these mutations, although with two jumps. In only two categories these nicknames apply: Variants of Concern (VOC) and Variants of Interest (VOI)). Currently, five correspond to the first and alone two to the second. The rest were “under alert and surveillance” or were removed from international scientific attention.

Nevertheless, After respecting the first 12 letters of the Greek alphabet, when variant B.1.1.529 was to be named, they found themselves at a crossroads, since the thirteenth letter is nu and the next is xi. As it transpired, the specialists defined to ignore them because, for the first case, its pronunciation was very similar to the sound of the English word new (new, in Spanish) and the second could be confused with one of the common surnames in China: Xi. To maintain order, if new variants emerge, they could be named as: pi, ro, sigma, tau, ipsilon, fi, ji, psi and omega.

In that sense, Maria Van Kerkhove, epidemiologist responsible for the management of the pandemic in the WHO, he warned that there are indications that Ómicron has a higher transmissibility, although he noted that it is not clear if it is more transmissible compared to other variants, including Delta. “Even if we have a large number of cases that are moderate, some of these individuals will need to be hospitalized, enter intensive care and some will die”, said the specialist and highlighted that “preliminary evidence suggests there may be an increased risk of reinfection (cured that re-infected) ”.

With regard to severity, the medical reference of the USA, Anthony Fauci, affirmed that the first indications indicate that it would be less dangerous than the Delta. “So far, it doesn’t seem like it has a very high degree of severity,” he said, adding: “We have to be really careful before making any determination that it is less serious, or that it doesn’t really cause serious illness.”
