CDC reports decreases in incidence rates for influenza, COVID-19, and RSV; yet levels remain very high.

These drops could be attributable to holiday-induced slowdowns; therefore, CDC is keeping an eye out for an increase in activity after each of the major holidays has concluded.

Key indicators of seasonal flu activity saw a reduction during the first week of 2019, suggesting an apparent relief from high respiratory virus transmission levels this season--but the reduction may only be temporary.

On Friday, the Centers for Disease Control and Prevention released their most recent flu data for the week ending January 6. Outpatient visits related to influenza-like illnesses (ILI) decreased dramatically that week - marking their first decrease after several weeks of steady increases - with flu test positivity declining slightly and hospitalizations also showing slight reduction.

However, transmission levels remain elevated nationwide: 14 states currently show ILI activity at "very high," down from 22 in previous data collection; 23 states exhibit high activity - an increase from 19 last week (you can view week-by-week progression of this season's flu season here.).

Flu isn't the only virus showing some relief in recent data reports; COVID-19 also experienced slight dips. According to the CDC, rates had stabilized or in some instances decreased after multiple weeks of steady increases 

CDC researchers believe some of the declines may be attributable to individuals forgoing medical attention during holiday-season visits as they would normally. COVID-19 wastewater activity levels continue to show strong or rising activity across all regions, with South and Midwest regions showing more elevated or increasing activity than their Midwest and Northeast counterparts - although recent data indicate some slowing in these increases over time. 

RSV activity remains high; however, in certain regions declines are being seen. 

CDC notes it is never too late to get vaccinated against COVID-19, flu and RSV; currently 21% of adult have received the 2023-2024 COVID-19 vaccination and 41.5 of people 65 or over have taken advantage of it so far. Since September alone 363,000 have died from this virus here. 

As for influenza vaccinations, approximately 47 percent of adults, including 74% of people ages 65+ have received their annual shots this season; 74% among people over age 65 received them as well. On Thursday, Canadian researchers published the initial estimates of vaccine effectiveness this season; it found the current annual shots are currently 61% effective against A(H1N1)pdm09 flu circulating throughout the US while only 49 % are effective against less frequent strains such as A(H3N2). They are 75 % effective against influenza B strains circulating around. 

CDC reports at least 14 million flu cases this season so far; 150,000 hospitalizations; 9,400 fatalities due to flu have also occurred so far; with 13 children dying this past week alone from flu infection bringing this year's total up to 40.
