CDC May Change the 5 Day Covid-19 Isolation Guidelines

I see many news headlines reporting that the CDC may be planning to drop the 5 day Covid-19 isolation guidelines. For now I’m taking that as a rumor until the CDC website says something official about it.

Word on the street is that we may know more in April.

CDC Healthcare Provider Toolkit

The CDC has a healhcare provider toolkit available to prepare their patients for the 2023 for the fall and winter virus season. It’s up to date and comprehensive.

CDC Issues Health Alert Network Announcement Recommending Vaccinations for Seasonal Respiratory Illnesses

The CDC recently issued a Health Alert Network (HAN) announcement urging physicians to recommend that patients get their influenza, Covid-19, and RSV vaccines.

CDC Weekly Update on Viral Respiratory Illness

As of December 8, 2023, the CDC reports:

“National test positivity, emergency department visits, and hospitalizations for influenza continue to increase. Influenza A(H1N1) is the predominant influenza virus circulating although influenza A(H3N2) and influenza B viruses are also being reported.
RSV-associated hospitalization rates remain elevated among young children and are increasing among older adults; of note, only 15.9% of adults 60+ report having received an RSV vaccine.
National vaccination coverage for COVID-19, influenza, and RSV vaccines increased slightly for children and adults compared to the previous week and remains low for both groups.”

However, the overall respiratory illness rates have gone from “moderate” to “low” in Iowa.

What’s Up with Intranasal Covid-19 Vaccines?

I saw the JAMA article on intranasal vaccines research for Covid-19. It starts off pretty supportive of the principle. However, at the bottom of the article, the outlook looks pretty stable for injectable vaccines for at least a good long while.

It’s an interesting read. Skip to the Many Questions section:

How these experimental mucosal vaccines stack up against mRNA vaccines, considered the standard of care, remains to be seen, Beigel noted. The NIAID intends to conduct phase 2 trials that would compare mucosal and mRNA vaccines head-to-head, “so you’d know for certain what you’re trading off,” he said.

Ideally, a mucosal vaccine would generate as good a systemic immune response as an mRNA vaccine as well as a robust mucosal immune response. But an excellent mucosal immune response might make up for a bit of a decline in the systemic immune response, Beigel explained. Perhaps a vaccine inhaled through the mouth and into the lungs could provide the best of both worlds—strong mucosal and systemic immunity—but there are no data yet to support that theory, he said.

“Everyone knows we need a better vaccine and would really like it if we could get something that interrupts transmission and stops even mild disease,” Beigel said. “Whether that’s attainable or not, we don’t know.”

I’m not knocking the concept by suggesting you read the Conflict of Interest Disclosures.

Moderate Respiratory Illness Activity in Iowa

The CDC tracks respiratory illness and there is moderate activity in Iowa according the data tracker.

The weekly snapshot as of December 1, 2023 shows highlights including:

“COVID-19 test positivity (percentage of tests conducted that were positive), emergency department visits, and hospitalizations have increased nationally. A group of Omicron variants (XBB and its sublineages) are the predominant lineages detected in the U.S., with HV.1 being most common. The prevalence of another lineage, BA.2.86, is projected to account for 5-15% of currently circulating variants. CDC continues to monitor HV.1, BA.2.86, and all other lineages.
National test positivity, emergency department visits, and hospitalizations for influenza continue to increase.
RSV emergency department visits and hospitalizations continue to increase across the country. RSV-associated hospitalization rates remain elevated among young children and are increasing among older adults; of note, only 14.8% of adults 60+ report having received an RSV vaccine.
National vaccination coverage for COVID-19, influenza, and RSV vaccines increased less than one percentage point for children and adults, where indicated, compared to the previous week and remains low for both groups.
CDC has been monitoring increases in respiratory illness reported recently among children, including potential elevated rates of pediatric pneumonia in parts of the United States. These reported increases do not appear to be due to a new virus or other pathogen but to several viral or bacterial causes that we expect to see during the respiratory illness season. CDC will continue to work closely with our state and local public health partners to maintain strong situational awareness and will provide updates, as needed.”

CDC Update on Covid-19 Variant BA.2.86

I saw a news item headline which mentioned Covid-19 Variant. BA.2.86. The CDC website tracking respiratory variants has a definitive update as of November 27, 2023:

“What to know about BA.2.86

The virus that causes COVID-19 is constantly changing over time. Sometimes these changes allow new variants to spread more quickly or effectively. If that occurs, the new variant may become more common relative to other variants that are circulating.
Since CDC’s first post on BA.2.86 in August 2023, the proportion of infections caused by BA.2.86 has slowly increased. In the CDC Nowcast posted Nov. 27, 2023, BA.2.86 is projected to account for 5-15% of currently circulating variants.
CDC projects BA.2.86 and its offshoots like JN.1 will continue to increase as a proportion of SARS-CoV-2 genomic sequences.
At this time, BA.2.86 does not appear to be driving increases in infections or hospitalizations in the United States.
CDC contributed to and agrees with the World Health Organization’s recent risk assessment about BA.2.86 suggesting that the public health risk posed by this variant is low compared with other circulating variants, based on available limited evidence.
Updated COVID-19 vaccines are expected to increase protection against BA.2.86, as they do for other variants.
As mentioned in previous updates, COVID-19 tests and treatments are expected to be effective against this variant, including its offshoot JN.1.
It is not possible at this time to know whether BA.2.86 infection produces different symptoms from other variants. In general, symptoms of COVID-19 tend to be similar across variants. The types of symptoms and how severe they are usually depend more on a person’s immunity than which variant causes the infection.
Regardless of what variants happen, CDC will continue to track them, working closely with partners around the world to understand how they are spreading and how they respond to vaccines and treatments.”

CDC Educates About Covid-19 Variants

Sometimes I see news about Covid-19 variants. They typically sound alarming. The CDC has posted an update on Covid-19 variants that is reassuring. There will always be variants. Not all will be serious threats. According to the update:

“While new variants like BA.2.86 and JN.1 attract attention, right now, 99 percent of SARS-CoV-2 variants are part of the XBB group of the Omicron variant, which is what this year’s updated vaccines are based on. CDC is continuing to track the spread and impact of BA.2.86 and JN.1, as well as other variants as they come and go.

For as long as we have COVID-19, we’ll have new variants. Nearly all represent relatively small changes compared with previous variants. CDC and other agencies monitor for impacts of new variants on vaccines, tests, and treatments, and will alert the public quickly if anything concerning is detected. Most of the time, new variants make little to no impact.

Regardless of the variant, all SARS-CoV-2 viruses spread the same way. So it’s important to protect yourself and others by staying up to date with COVID-19 vaccines, improving ventilation and staying home when you’re sick.”

CDC on How to Get Flu, Covid-19, and RSV Vaccines

The latest update on how to get the respiratory viruses vaccines is updated on the CDC website. Highlights:

“f you have insurance, these vaccines should be free to you in most cases.
Adults without health insurance or adults whose insurance doesn’t cover all COVID-19 vaccine costs can get an updated COVID-19 vaccine for free through the Bridge Access Program.
Most children can get recommended vaccines for free through their family’s insurance or the Vaccines for Children (VFC) Program.
How COVID-19 vaccines are being distributed changed in September 2023 when these products moved to the commercial market, but there is still plenty of vaccine supply.
Flu, COVID-19, and RSV vaccines may be given at the same visit.”
