In Mexico already circulate the new variants of ómicronof the covid-19 virus, called BQ.1 and BQ.1.1, whose contagiousness and spread is 30 times greater than the other mutations identified, in addition to evading the response of any applied vaccine, according to scientists from the United States CDC States and with the United Kingdom Public Health Agency (UKHSA).
On the GISAID platform (Global Initiative on Sharing All Influenza Data), the National Institute of Genomic Medicine (Inmegen) reported the first case with BQ.1 in a 40-year-old woman, from Mexico City, who underwent the test in the Salud Digna laboratories on September 20, 2022, and whose results were obtained on October 3, 2022.
For its part, the Institute of Epidemiological Diagnosis and Reference (Indre) reported the second case of BQ.1 in a 45-year-old woman from Querétaro, who attended local services on October 7, 2022 and whose result with the new variant occurred twenty days later, that is, on October 27, 2022.
The Indre also identified the BQ.1.1 variant in a 48-year-old woman, in Mexico City, whose sample was taken on October 5, 2022, in a local laboratory and the confirmation of said variant until October 27 of this year.
In the past week, the World Health Organization (WHO) reported that BQ.1.1 has been found in 29 countriesdisplacing the one that was, until now, predominant of ómicron, the BA.5 and various lineages.
The US Centers for Disease Control and Prevention (CDC) stated that BQ.1 and BQ.1.1 are grandchildren of BA.5.
They currently account for nearly 17 percent of infections in that country, a clear increase considering that until a few weeks ago they represented zero. The predominant variant BA.5 is beginning to be displaced. Those who are not vaccinated and those who have not received a dose of the new boosters are especially at risk, according to the CDC.
As for those hospitalized, 40 percent were positive for this variant of covid-19 among those vaccinated and with booster doses, “the new variants have mutated and without further ado able to more easily evade the immunity offered by vaccines current”, so CDC scientists stressed the importance of having more effective vaccines.
“One reason for concern is that BQ.1.1 evades immune systems on a larger scale than other variants and sub-variants. The new variant already has the potential to render obsolete the drug Evusheld, key to protecting immunosuppressed people. The number of cases appears to be increasing rapidly in New York and could spread across the country in the coming months.”
Those infected present the same symptoms, such as fever or chills, cough, shortness of breath or shortness of breath, fatigue, muscle or body aches, headache, loss of taste or smell, sore throat, stuffy or runny nose, nausea or vomiting, and diarrhea.
Meanwhile, the European Center for Disease Prevention and Control (ECDC) recently warned that the new omicron subvariants “are about to become dominant in Europe and will likely drive another increase in covid-19 cases.” .
The subvariant BQ.1 and its sublineage BQ.1.1 will likely dominate in Europe from mid-November until early December and will help increase cases in the coming weeks or months, the agency said.
It is a descendant of the BA.5 variant of omicron, which is prevalent throughout the world. The first samples of BQ.1 and BQ.1.1 were identified in Nigeria in mid-July. Since then, these variants have been found in countries in Europe, America, Asia and Oceania.
Regarding centaurus, Inmegen continues to register a single case with the BA.2.75 lineage, in a 43-year-old woman from Mexico City, whose case is under epidemiological surveillance. There are no updates.
Another variant: BF.7
In Mexico, seven cases with the BF.7 variant of omicron have already been identified, the last one in a 60-year-old woman from Mexico City, who came to care and was tested on August 25, 2022 and it was the Indre who announced this mutation on September 5 of this year.
The first case reported in the country was in a 21-year-old woman from Mexico City, who went to the Salud Digna laboratories on August 1, 2022 and Inmegen uploaded the positive result on August 17.
In Mexico, a cumulative of 78,547 cases have been reported with the omicron variant of covid-19, the most recent in a 57-year-old man, who underwent the studies on September 26, 2022 in the state laboratories of the City of Mexico.
The result was given by Indre on October 27, 2022. It was positive for BA.5.2, which continues to circulate and which, according to experts, will be displaced by BQ.1 and BQ.1.1.
