Dr. Carlos Ortega, a specialist in virology, explains that “there are variant sublineages of the virus that cause reinfection,” and warns that there is data that suggests that the Coronavac vaccine is less effective than the rest.
Dr. Carlos Ortega speaks of the Coronavirus from double experience: as a virologist, he has worked for months in the study of SARS-CoV-2 and its genetic structure in the laboratory of the University of El Salvador; as just another citizen, his family got infected and they had to fight the disease.
“We have seen more people hit by the disease, more people saying ‘my son, my neighbor, my brother is complicated’, we see how the circle is closing,” warns the virology specialist. Why have cases risen and we are experiencing a third outbreak? We talked about that and more in this interview.
The virus specialist from the Faculty of Medicine of the University of El Salvador comments on the third wave of COVID-19 cases in El Salvador, vaccines, reinfections and lack of official data
Why is this third outbreak of covid infections occurring in the country? This behavior was already expected, what’s more, a fourth wave is still expected. Countries like Mexico, the United Kingdom and other South Americans are in a third wave and some in a fourth. Of course, we would hope that this fourth wave is with fewer deceased and complicated patients, that it is not like this third, which is causing havoc. We are with a number of deaths similar to the moments when the situation with the restrictions was tense.
But what is causing this new wave of cases? This can be explained by the appearance of variants of the virus, but these variants have been generating subvariants or sublineages, and some of these have been prevailing with a little greater transmissibility, and this can cause us new infections and even reinfections. In addition, the population has stopped taking biosecurity measures, it has been neglected.
So the virus is reinfecting more people who already had it? This has already been seen in other countries, of people who had been infected by a variant of interest or not so transmissible, and that with the advent of the delta variant, or worse still, with a subvariant of this or the lambda variant of South America , at some point they may present greater transmissibility and that they can be reinfected.
There is data (globally) that out of every five to six people one is reinfected, by the new variants. We are crossing both new and reinfected infections, even though they have the vaccine.
