Covid-19. It is too early to fear the C.1.2 variant

The spread of viruses and information on social networks are often rightly compared. New example with the media outbreak around the C1.1.2 variant of Sars-CoV-2. It was particularly fueled by tweets from the American epidemiologist Eric Feigl-Ding, a public health specialist and compulsive twitter, but not a specialist in infectious diseases.

Indeed, a South African preliminary study, published on August 27, describes a line of variants which quickly accumulated mutations recognized as potentially worrying, to which are added other mutations which can play on the resistance to the antibodies and the replication of the virus. .

A variant to watch closely

Undoubtedly, C.1.2. is a customer to watch closely, already present in South Africa and in seven countries. The American researcher’s shortcuts, prophesying a variant quickly becoming problematic, have been extensively repeated. They are criticized by authors of the South African study, including Professor Tulio de Oliveira.

While the accumulation of these mutations is not a good sign, it does not necessarily presage a capacity of the variant to generate serious cases or to completely avoid current vaccines. Above all, this emerging line has not yet shown that it can take precedence over the dominant variants. Is the high contamination capacity of the Delta variant a good thing? May be.

Too early to worry

It is in any case too early to worry about this C.1.2 lineage. In the immediate future, the WHO lists five disturbing variants (VOC), including the Delta which circulates almost exclusively in France; six monitored variants “to follow” (VOI). Eight others are under evaluation (VUM), not yet C.1.2.
