Seems like there's an attempt to start fear mongering for a new variant. It's the usual spiel; more contagious etc. Although this quote is interesting to note:
Is the 'Kraken' variant more dangerous?
For now, it doesn't seem to be.The WHO is still assessing XBB.1.5 but notes that it doesn't have any mutations that make people sicker than the other variants.
"It's certainly something to keep an eye on, especially for those who are particularly vulnerable," [Leslie Waller, an epidemiologist with the Metro Public Health Department.] said. "But, in terms of worry and panic, I don't think that's particularly warranted at this time. There's not currently any indication that it makes people sicker."
More contagious, but less dangerous? Whatever.
