The Institute for Epidemiological Diagnosis and Reference (Internal) confirmed yesterday Monday the presence of the brazilian variant of Covid-19 in Mexico, which was detected by the a University of Guadalajara (UdeG).
Dr. José Francisco Muñoz Valle, rector of the University Center for Health Sciences and General Coordinator of the Health Situation Room, said that the mutation identified as E484K “It is one of the most worrying.”

Muñoz Valle explained that this mutation of the Covid-19 has been associated with decreased neutralization of virus up to 10 times, and is identified in the South African and Brazilian variants (P.1 Y P.2).
“It could happen is that the vaccines have a lower efficacy or that reinfections occur, but studies are lacking to verify to what extent the efficacy of the vaccine“Said the expert.
More than a thousand samples are analyzed
Muñoz Valle added that more than a thousand samples, corresponding to the Metropolitan Area of Guadalajara Y Vallarta Port, where the four cases of the brazilian variant of coronavirus.
He added that at the moment, there are another 9 samples of Covid-19 in the process of validation, so that “the implication that this mutation could have cannot be determined”.

The doctor reported that the UdeG defined to start with a Molecular Epidemiological Surveillance System to SARS-CoV-2 in samples from positive patients that allow the implementation of effective control strategies against Covid-19.
“It is important to know how the patients’ symptom behavior occurs. At the moment, the cases that were detected were not serious and that leaves us calm, but there are few samples, “he said.
He explained that having this surveillance system will allow identifying to what extent the frequency of this mutation of Covid-19, which will contribute to the control of pandemic.
