"Dr. Zeller, I may be the slowest, but I also may be the most grateful for the 'Walk with the Doc' program. 

That program not only introduced me to the park but also gave me incentive to lose the weight that has been creeping up for years.  In addition, it shows me that my doctors are serious about helping their patients while providing the opportunity to meet in a relaxed atmosphere.  That will translate into making office visits less stressful."

COVID-19 UPDATES (1/10/22)

Hello Kolvita Family,

We are in the midst of one of the largest spikes in Covid cases over the past 2 years.  The good news, overall, is that the majority of cases are exhibiting milder symptoms and less life-threatening complications.  However, this does not mean that those who are high risk or are around those who are risk should not continue to be as careful as possible.  We are still seeing a rise in hospitalizations in the OC.

Due to the high demand for Covid testing, we have had a back-order on tests in our office.  Unfortunately, this means we can only utilize the tests we do have for our patients (not any family/friends who are not members) and only those that are symptomatic or with high risk exposure.  We have also seen many patients test negative on a Rapid Antigen test initially and then test positive after 3-5 days.  We recommend that if you are symptomatic and a rapid test is negative, get a PCR test and/or recheck a Rapid test in 3-5 days.

IF YOU TEST POSITIVE OR ARE EXPOSED, here is the updated guidance by the California Department of Public Health (see the included tables): 



- The Orange County Health Department (OCPH) reports that Omicron represents anywhere from 85% to 92% of all Covid cases.  It was also reported that the most common monoclonal antibody treatment options we have are NOT effective against the Omicron variant.  Thus, the OCPH department has suspended the distribution of antibody infusion medications.  The one monoclonal antibody medication that is effective against Omicron is in a severe shortage and is only being used in OC hospitals for those at highest risk for poor outcomes.
- The oral antiviral medications that are effective against Covid will be distributed to limited pharmacies in South Orange County.  We do not know when they will be available, but we do know they will be in limited supply and will be given out to high risk individuals first.  The five locations locally will be CVS pharmacies:  CVS on Antonio Parkway in RSM, CVS on Muirlands in Lake Forest, CVS on El Camino Real in San Clemente, CVS on Paseo de Valencia in Laguna Woods and CVS on Harvard in Irvine.
- the FDA has approved the booster of the Pfizer vaccine for youth ages 12 to 15 years old.  It is to be given 6 months after the second vaccine.
- NEJM study reports that blood levels in individuals with the highest neutralization of the Omicron variant are those who have had the booster of Moderna or Pfizer.  The neutralization of Omicron in these individuals was much higher than those with a history of previous infection or those with just the primary vaccine series.
- the British Journal of Medicine report shows that Omicron more effectively invades nasopharyngeal tissue than it does in lower respiratory tissue--this is a major reason we are seeing more mild, upper respiratory symptoms and less ICU intubations or pneumonia cases than previous spikes.

Orange County Numbers (as of 1/7/22)

- 38,697 new cases the past 7 days (17,332 the previous 14 days) 
- 16 deaths the past 14 days (39 the previous 14 days)
- 779 hospitalized patients (420 last week)
- 122 ICU patients (86 last week)
- 3-day average change in hospitalized patients is +29.4% (+45.8% one week ago)
- As of 1/7/22, Covid + rate for vaccinated individuals is 108.5/100,000 (previous 21.6/100K on 12/25/21)
- As of 1/7/22, Covid + rate for unvaccinated individuals is 180.1/100,000 (previous 83.0/100K on 12/25/21)
* Percentage of hospitalized patients that are unvaccinated: 87%
* Percentage of ICU patients that are unvaccinated: 88%
