Recently, a new variant of the SARS-CoV-2 virus has emerged, known as ‘Frankenstein’. This nickname raises concerns, but is the fear justified? In scientific terms, this variant is classified as XFG and belongs to the Omicron family. It has become predominant in countries such as France, the United Kingdom, and the United States, according to sequencing data from positive cases.
Classification and Surveillance of the Variant
As of late June, the World Health Organization (WHO) has categorized XFG as “under surveillance.” This classification is due to its increased infectivity compared to previous variants. As the epidemic shows signs of resurgence, understanding the reasons behind the variant’s ominous nickname is essential.
Origin of the Nickname ‘Frankenstein’
The exact origin of the ‘Frankenstein’ name remains somewhat ambiguous. It appears to be a term that gained traction especially over social media. The name was initially popularized in a sensational article published by the Daily Mail on July 3, which titled it “Ultra-contagious Frankenstein variant has quadrupled in a month.”
In previous years, other variants had been given names inspired by Greek mythology, like Centaur and Kraken. Evolutionary biologist T. Ryan Gregory pointed out that these names were meant to fit within the Greek letter system used by the WHO, making them familiar to the public. However, this choice has drawn criticism from epidemiologist Antoine Flahault, who emphasized the need to remain calm amidst such alarming terminology.
Understanding XFG: A Recombinant Variant
XFG has earned its nickname because it is a recombinant variant, created from a mix of two prior strains: LF.7 and LP.8.1.2. The ‘X’ in XFG indicates that it is a recombinant. The Global Vaccine and Immunization Alliance (Gavi) noted that these recombinant variants are constructed through genetic recombination.
Health Implications
- XFG is still classified as a variant “under surveillance.”
- Current data suggests no increased severity in symptoms or long-term effects compared to prior variants.
In conclusion, while the ‘Frankenstein’ name may evoke fear, it is crucial to approach this variant with measured caution rather than hysteria, as it does not indicate a heightened health risk compared to its predecessors.
