New Covid Variant KP.2 Emerges in California: Potential Summer Surge Amidst Increasing Wastewater Levels and Travel

California and other parts of the country are experiencing an increase in Covid cases due to the emergence of a new variant called KP.2, which is overtaking the dominant Covid variant in the US. This raises concerns for a potential summer surge in cases across California and the nation. The rate of Covid spread has been relatively low this year due to immunity from vaccines and past infections, but wastewater levels have been increasing since mid-May, particularly in the West where California has the highest levels. Dr. Ashish Jha, dean of the Brown University School of Public Health and former White House COVID-19 response coordinator, expects a summer wave of Covid-19 cases due to travel and air-conditioned gatherings. The new variant KP.2 belongs to a group called FLiRT variants which are a subset of Omicron tree variants. One change from JN.1 in KP.2 could significantly impact F456L, possibly enhancing ACE2 binding affinity or decreasing antibody binding efficiency, and V1104L has been added to the S2 subunit of the spike protein in KP.2 which may improve the efficiency of fusion with host cell membrane and viral genome entry. The variant shares three mutations with the first departing variant from the original Wuhan virus: D614G in the spike, P323L in NSP12, and C241U synonymous mutation. Synonymous mutations in KP.2 influence the tertiary structure of its RNA and can contribute to adaptation to human host environment, impacting the abundance of viral proteins and immune responses in infected individuals.

  • Deception (30%)
    The article contains selective reporting and emotional manipulation. The author focuses on the potential increase in COVID cases caused by new subvariants, while downplaying the fact that deaths and hospitalizations have significantly decreased since the pandemic began. This creates a sense of fear without providing proper context. Additionally, statements from experts are used to add credibility to this narrative, but they do not provide any new information or insights beyond what is already known about COVID-19.
    • Experts generally believe they are more contagious than earlier strains
    • But even with lower deaths there can be a high number of infections
    • California’s COVID waves last summer and winter were still big enough to cause significant disruptions
    • COVID deaths have continued to decline: For the 12-month period that ended at the start of spring, there were about 66,000 deaths nationally, half as many as the prior comparable period.

    The author makes several statements that are based on facts and do not contain any logical fallacies. However, there is one instance of an appeal to authority when the author quotes Peter Chin-Hong, an infectious disease specialist at the University of California, San Francisco. This does not significantly impact the overall score as it only represents a minor portion of the article.
    • “The writing is on the wall in terms of a small uptick,” Peter Chin-Hong, an infectious disease specialist at the University of California, San Francisco, told me.
  • Bias (95%)
    The author expresses a bias towards the likelihood of a summer Covid surge in California by stating 'The answer is probably yes.' and 'I think it will continue to swell a bit.'
    • I think it will continue to swell a bit.
      • The answer is probably yes.
