A new Covid variant it also arrived in Italy. It’s about the KP.2, which in the United States has become the most widespread and causes 1 in 4 cases. “Americans are worrying about this latest variant that derives from Jn.1. KP.2 has three interesting mutations but in the USA they are worrying a little too much” explained the epidemiologist Massimo Ciccozzi on the pages of beraking latest news Salute. Ciccozzi is among the authors of a study by the Campus Bio-Medico University of Rome dedicated precisely to KP.2 variant e pubblicato su ‘The Journal of Infectious Diseases’.
The expert explains that “one of these mutations is at site 455, a ‘flip mutation’”. This is capable of changing the amino acid and destabilizing the structure of the protein. According to the epidemiologist, however, this “does not mean that it is more immunoevasive”. Therefore “it does not elude i anti-Covid vaccines” and furthermore it is no longer dangerous. This new variant also resembles Delta even if it is less aggressive, as underlined by the expert, who then explains: “Our study shows that there are no risks of greater virulence and evasion of the immune system, it will tend to replace the previous variants”.
Covid variant KP.2, Ciccozzi: “No to useless alarmism”
The mistake you are making with the Covid variant KP.2 is to “confuse evolutionary fitness with contagious fitness” according to Massimo Ciccozzi, epidemiologist. The expert, at beraking latest news Salute, explains that one thing is the ability to adapt or evolutionary fitness while another is gravity or contagious fitness. Covid is different from other viruses such as Ebola, which, despite its low contagiousness, was lethal for those who contracted it.
According to Ciccozzi, in fact, with Covid “if the ability to adapt increases, the ability to adapt decreases severity of disease. However, it is good to monitor the virus, without creating unnecessary alarmism.” Don’t worry, therefore, not even with this new variant of the virus which does not seem to cause particular concern among experts.
