Covid BA.2 Omicron Subvariant Is On The Rise – New Study Addresses Its Severity

The novel coronavirus remains in the spotlight these days due to a new subvariant of Omicron. While we reported a while ago that Omicron is not causing severe symptomatology, CNN now reveals that this new variant may post more risk signs, unfortunately.

CNN cites data from a new Japanese study and notes some pretty intriguing news.

They call the new variant “a subvariant of the Omicron coronavirus variant which isn’t just spreading faster than its distant cousin, it may also cause more severe disease and appears capable of thwarting some of the key weapons we have against Covid-19, new research suggests.”

Japan lab experiments 

The new lab experiments from Japan are showing the fact that the new subvariant could come with features that make it capable of causing “serious illness.”

CNN also makes sure to note the fact that Omicron managed to escape covid vaccines. 


CNN notes the fact that the findings were posted Wednesday as a preprint study on the bioRxiv server, before peer review. It’s also important to note the fact that before a study is published in the medical journal, it is scrutinized by independent experts.

The same article notes that preprints allow research to be shared more quickly, but they are posted before that additional layer of review.

This is a worse virus than BA.1, experts say 

“It might be, from a human’s perspective, a worse virus than BA.1 and might be able to transmit better and cause worse disease.”

This is what Dr. Daniel Rhoads, section head of microbiology at the Cleveland Clinic in Ohio said. Rhoads reviewed the study but was not involved in the research.

Experts also made sure to note the fact that this new Omicron variant is called stealth Omicron. This is due to the reason that it does not show up on PCR tests as an S-gene target failure. It’s been also revealed that laps are now having to take an extra step and sequence the virus in order to find this variant. CNN suggests that you check out the preprint variant of this study as well.
