This is what we know about ‘Centaurus’, the sub-variant of Covid five times more contagious


the pandemic of Covid-19 continues with the appearance of new variants and subvariants of the coronavirus before the transmission of versions of this virus that have mutated over more than two years since the emergency was declared by the World Health Organization (WHO), such is the case of BA.2.75, better known as ‘Centaurus’.


One of the particularities of this omicron sublineage is that, according to the first analyzes by specialists, the branching of SARS-CoV2 is up to five times more contagious since its appearance in India, the country that also saw an exponential growth of the delta variant a few months ago.

“Less than a month after its detection in India, it already represents the 20% of Covid-19 infections″, indicated the director of the Social Security Institute of the State of Mexico and Municipalities, Dr. Jorge Guerrero Aguirre.

In the midst of infections BA.4 and BA.5which in countries like Mexico are responsible for the fifth wave of the Covid-19 pandemic‘Centaurus’ has a presence in other nations, outside its place of ‘origin’, such as United States, Germany, Australia and Canadaalthough it is not ruled out that thanks to the summer vacation period it will expand around the world.

In this way, the World Health Organization (WHO) has not discovered in depth what its level of evasion of immunity from vaccines or if it causes an increase in lethality; however, the monitoring carried out by this institution is detailed, in order to avoid its consequences in the medium term.


“’Centaurus’ accumulates a range of mutationsbut an important part in the region of the spicule and these are important because this element is the key to infect human cells”, specified the director of the Mexican health institution.

Thus, due to the conditions of the version of this coronavirus, ‘baptized’ as ‘Centaurus’, the concern of the scientific community has escalated, since the virus would become more “slippery”according to Jorge Guerrero Aguirre, and would infect vaccinated people and would affect, to a greater extent, those who did not receive the biological.

  • Cough
  • Fatigue
