Mexico detected the first case of the BA.5 omicron subvariant, which has lower immunity to the Covid-19 vaccine.
But it is not the only one, since the BA.2.12.1. according to the platform GISAIDthere is already a record of a case of this type of covid-19.
This platform details that the case occurred in a 45-year-old man, who went to a laboratory of the Mexico state to undergo a test coronavirus.
This variant has tripled cases of the disease in Hon Kong, South Africa and Botswana.
Some evidence shows that this variant it increases considerably faster than the visyas so far as far as the Omicron is concerned.
According to the World Health Organization (WHO) pointed out that omicron BA.4 and BA.5 have led to the increase in the disease in South Africa.
For its part, the Pan American Health Organization (PAHO) a call to strengthen prevention measures against the virussince hospitalizations begin to register increases in different parts of the world.
It should be noted that after an analysis of BA.5, it was noted that there was a drop in the production of neutralizing antibodies of almost eight times; figure that has alerts to doctors.
Sub variant BA.5 of omicron: What is known about it?
According to the University of Massachusettsthe European Center for Disease Prevention and Control (ECDC) designated the subvariants BA.4 Y BA.5 omicron What concern variants (VOC) beginnings of May.
The subvariant BA.5 from omicron was first detected in South Africa in February 2022 and the requirement to be considered as VOC is that there is clear evidence available indicating a major impact on transmissibility, severity and/or immunity possibly impacting the epidemiological situation.
In this international database, an increase in the sublineage of omicron BA.2.12.1which caused a new confinement in China and an accelerated contagion of cases in USA.
It is not yet known whether the subvariants of omicron are more serious
According to the specialist World Health Organization (WHO), Mary Van Kerkhovethe severity of the condition that can be caused by the subvariant BA.5but it has been shown to be more contagious than the other forms of omicron.
“These new strains of omicron (BA.4 Y BA.5) are even more transmissible than BA.2which is the dominant coronavirus in Ireland and across the globe. We keep in mind that BA.4 Y BA.5 they have growth advantages, making it easier to transmit. All of this highlights the importance of surveillance and sequencing,” explained the expert from the WHO.
