Of specific concern is the rise of a hyperinfectious subvariant referred to as KP.3.1.1, which is so contagious that even individuals who have eluded an infection all through the pandemic are getting sick.
“This can be a very massive surge that we’re seeing at the moment. That is beginning to rival, actually, what we noticed this previous winter,” mentioned Dr. Elizabeth Hudson, regional chief of infectious ailments at Kaiser Permanente Southern California.
Coronavirus ranges in Los Angeles County wastewater are persevering with to rise, in accordance with probably the most just lately accessible information. And viral ranges in California wastewater are at “very excessive” ranges as outlined by the U.S. Facilities for Illness Management and Prevention.
Coronavirus ranges within the state’s wastewater have been down 3% when evaluating the week that ended Aug. 10 with the prior week, a potential indication that ranges are cresting — though it’s additionally potential that coronavirus ranges will proceed to extend. Seasonal viral ranges in sewage are anticipated to peak in some unspecified time in the future, but it surely received’t be clear till just a few weeks of constant declines are noticed.
Listed below are some issues that specialists say you are able to do to maintain your self protected:
Get examined
Medical doctors are urging folks coping with respiratory sickness signs — together with healthcare suppliers — to hunt testing.
Dr. Abraar Karan, an infectious ailments knowledgeable and epidemiologist at Stanford College, mentioned affirmation of a COVID-19 prognosis would assist a affected person get a Paxlovid prescription to assist deal with the sickness, whereas affirmation of one other sickness, just like the flu, may assist a affected person get a drug extra focused towards that ailment.
An preliminary destructive take a look at doesn’t imply you don’t have COVID; docs counsel testing for so long as 5 days after the onset of signs to find out whether or not a take a look at turns constructive.
Extra constant testing at medical services additionally may assist detection of surprising strains that epidemiologists wish to observe, akin to hen flu.
Hen flu has attracted consideration just lately due to outbreaks in poultry and dairy cows, and there have been a number of latest human circumstances amongst dairy and poultry employees within the U.S., in accordance with the CDC.
The rise of hen flu
Current human circumstances of H5N1 hen flu have resulted in primarily delicate signs, together with conjunctivitis, often known as pink eye, Karan mentioned.
However one purpose docs are intently monitoring the scenario is that, within the a long time wherein we’ve been conscious of hen flu infecting people, some H5N1 strains have resulted in important mortality charges.
In line with the CDC, human infections with H5N1 virus, which have been reported in 23 nations since 1997, have resulted in extreme pneumonia and demise in about 50% of circumstances.
Now that we all know hen flu has contaminated cows, and there’s cow-to-human transmission, that poses a possible drawback.
“Cow udders have receptors in frequent with birds, and so they even have receptors in frequent with people, the place these viruses bind,” Karan mentioned.
“Now, with human flu season coming, you might have the chance of what’s known as viral reassortment, the place a bunch can get contaminated with each hen flu and human flu on the similar time, and people flus now begin swapping genetic materials,” Karan mentioned. “That is form of how swine flu occurred [in 2009]. So that is the place we’re actually apprehensive. It’s like a ticking time bomb of human flu season across the nook, and but we nonetheless have this uncontrolled unfold of hen flu in cows.”
Hen flu hasn’t resulted in sustained human-to-human transmission, nor brought about a pandemic in people, in latest occasions.
“However it’s a kind of pathogens that’s excessive threat of mutating to some extent of accelerating transmissibility. And the pathogen has had excessive virulence primarily based on historic circumstances. … It’s the chance of the place it may go,” Karan mentioned.
Monitoring the unfold
This illustrates why it may be vital for sufferers to get examined. If a take a look at reveals that an individual has the flu, subsequent screening — together with genetic subtyping — may finally decide whether or not it’s hen flu. And that might assist epidemiologists work out how the hen flu could have unfold and assist docs decide the perfect course of therapy.
Even when a case of hen flu ends in delicate signs, it’s vital to diagnose it, Karan mentioned, so the virus pattern may be genetically analyzed and scientists can observe the place it jumped from animal to human, and doubtlessly extra aggressively deal with the affected person with antivirals.
“However think about — that solely occurs if I even take a look at that affected person for flu in any respect,” Karan mentioned.
The place hen flu stands within the U.S.
Since 2022, in accordance with the CDC, there have been 14 reported human circumstances of H5 hen flu within the U.S., 13 of which have been reported since March 24. Of the 14, 9 have been confirmed as H5N1.

Hen flu has been detected in wild birds in most counties of California, together with all of Southern California and the San Francisco Bay Space, and many of the Central Valley.
Hen flu outbreaks — these involving business poultry services or yard poultry and hobbyist hen flocks — in California have been reported in only one county in Southern California: San Diego County. Hen flu outbreaks have occurred in plenty of counties in Northern and Central California, together with Sacramento, Contra Costa, Fresno, San Francisco, San Joaquin, Stanislaus, Sonoma, Monterey, Placer, Merced and Marin counties.
As for hen flu infecting dairy cows, 13 states have reported outbreaks — Idaho, Wyoming, Colorado, New Mexico, Texas, Oklahoma, Kansas, South Dakota, Minnesota, Iowa, Michigan, Ohio and North Carolina. Within the final month, outbreaks infecting dairy cows have affected 5 states: Idaho, Colorado, Texas, South Dakota and Michigan.
In Could, there was a detection of hen flu in a stay hen market in San Francisco, in accordance with the California Division of Meals and Agriculture. State officers urged folks to separate poultry from wild birds if potential.
“Due to the latest case in California poultry manufacturing and epidemiologic proof that this pressure was launched by wild birds, we ask that California producers transfer their birds indoors by December 2024,” the California Division of Meals and Agriculture mentioned in June.
Defending household and associates
The CDC earlier this 12 months eased COVID isolation steering, on condition that the well being impacts of COVID-19 are decrease than they as soon as have been, because of the provision of vaccines, anti-COVID medicines and elevated inhabitants immunity.
There are fewer folks being hospitalized and dying, and fewer reviews of problems akin to multi-inflammatory syndrome in kids.
Nonetheless, docs say it stays prudent to take commonsense steps to keep away from sickness and spreading the illness to others, on condition that COVID nonetheless causes important well being burdens that stay worse than the flu. Nationally, for the reason that begin of October, greater than 49,000 folks have been reported to have died of COVID; in contrast, flu has resulted in not less than 25,000 fatalities over the identical time interval, in accordance with federal estimates, which will probably be up to date later this 12 months.
Whereas the prevalence of lengthy COVID has been happening, lengthy COVID can nonetheless be a threat any time somebody will get COVID.
Medical doctors are urging everybody to rise up thus far on vaccinations — notably if sufferers are at larger threat of extreme problems from COVID-19.

- Keep away from others whereas sick
The CDC recommends folks keep house and away from others till not less than 24 hours after their respiratory viral signs are getting higher general and so they haven’t had a fever with out utilizing fever-reducing drugs akin to Tylenol or Advil. Beforehand, the CDC steered folks with COVID isolate for not less than 5 days and take further precautions for just a few extra days.
By way of deciding when signs are getting higher, what’s most vital is “the general sense of feeling higher and the power to renew actions,” the CDC says. A lingering cough by itself can final past when somebody is contagious, the CDC mentioned.
However the CDC additionally advises added precautions for 5 further days to keep away from infecting others, akin to carrying a masks, opening home windows to enhance air circulation, washing fingers usually, holding one’s distance from others and persevering with to check. It’s potential for contaminated folks to be contagious even after they really feel higher.
The Los Angeles County Division of Public Well being suggests contaminated individuals who have signs get a destructive take a look at consequence earlier than leaving isolation. The company additionally suggests those that are contaminated — no matter whether or not they have signs — put on a masks round others for 10 days after they begin feeling sick or, if asymptomatic, their first constructive take a look at consequence. Nonetheless, they will take away their masks sooner if they’ve two sequential destructive assessments not less than at some point aside.
The company suggests staying away from the aged and immunocompromised folks for 10 days after you begin to really feel sick, or, if asymptomatic, after their first constructive take a look at consequence.
If sufferers recuperate after which get sick once more, they could have COVID rebound and want to remain house and isolate from non-infected folks of their family.
