Coronavirus prevalence in North Park County was relatively flat in the last week, based on the latest wastewater surveillance data, despite recent hints of the drop following the aggressive spread from the BA.5 variant through the region.
It’s another pattern than was seen throughout the original Omicron wave last winter when the amount of coronavirus copies per liter of wastewater peaked on Jan. 9 at 47 million per liter of wastewater, then fell dramatically, shedding 16 percent per week and falling underneath the a million mark on March 8, based on reports from San Diego’s SEARCH research coalition.
The form around the epidemic curve is really a classic spike — dramatically up, then dramatically lower.
However the latest pattern is flatter.
Surging rapidly as much as 19.8 million copies per liter on This summer 26, counts fell to 18.a million the very next day however reversed course, surpassing 19 million on This summer 31 and August. 1 then nearing 20.a million on August. 2 before falling to 17.a million on August. 3.
Nationwide, the pattern varies by location using the Off-shore Northwest showing declines in the quantity of virus detected although some Midwest states continue to be seeing significant increases, based on the latest wastewater COVID-19 surveillance data collated through the U.S. Cdc and Prevention. It is not easy to obtain a current picture of nationwide activity, however, because some sites are considerably slower to publish new updates than the others.
What’s creating a different pattern for BA.5 than was seen for Omicron, its ancestor?
Kristian Andersen, an immunologist and molecular bioligist at Scripps Research, among the groups collaborating on San Diego’s wastewater surveillance reports, stated within an email the plateau pattern now visible within the information is “probably a mix of still-altering human behavior, faster-waning immunity, and, obviously, ongoing virus evolution that keeps chipping away at protection against infection (and) transmission.”
Andersen stated that although wastewater figures likely will fall a little reduced the approaching week, he doesn’t “really think we’ll begin to see the same steep decline once we did for BA.1,” the initial Omicron variant.
Dr. David “Davey” Cruz, a translational research virologist at UC North Park, stated that reinfection also seems to become playing a job. Individuals who got infected this spring, he noted, haven’t much potential to deal with BA.5.
“I believe that there are plenty of people still prone to BA.5 this level will remain high for some time,” Cruz stated within an email.
Confirmed cases have proven an identical flat pattern, with 1,446 positive test results conveyed towards the county health department Wednesday, slightly less compared to 1,678 listed 1 week earlier. COVID-related hospitalizations have declined slightly, with 435 in non-military hospitals Wednesday when compared with 464 the prior Wednesday, This summer 27.
