New ultra-contagious Omicron subvariants BA.4, BA.5 worsening California coronavirus wave
Source: LA Times
The growing dominance of two new ultra-contagious Omicron subvariants is prolonging a wave of coronavirus cases in California and sparking growing concerns from health officials that coming weeks could see significant spread and increased hospitalizations.
BA.4 and BA.5 are now believed to be responsible for most new infections nationwide. The strains are of particular concern because they are not only especially contagious but also capable of reinfecting those who have survived earlier Omicron infection.
When it comes to BA.4 and BA.5, their superpower is reinfection, said Dr. Peter Chin-Hong, a UC San Francisco infectious-disease expert.
Additionally, theres strong evidence they can spread even faster than other subvariants, said Los Angeles County Public Health Director Barbara Ferrer.

(34,060 posts)There are learning disabilities which prevent individuals from recognizing misspellings - or from choosing the correct suggestion from a spellcheck program. I had a student who failed a licensing exam on their first attempt because of this disability - so yes, misspellings can be the equivalent of stuttering.

If you thought Covid-19 was dead and gone, think again. Early signs indicate that the UK may be at the start of a new wave of Covid infections driven by BA.4 and BA.5 while new data suggests these variants may have evolved to refavour infecting lung tissue, which could make them more dangerous. So what can we expect in the coming weeks and months? Although BA.2 continues to account for the bulk of UK infections, data from the Office for National Statistics up to 2 June suggests that Covid cases may be starting to rise again in England and Northern Ireland, driven by an increase in BA.4 and BA.5 infections.
(snip)
According to research published in Science on Tuesday, natural infection with Omicron doesnt produce a strong immune response, regardless of whether scientists look at antibodies or T-cells meaning that people who have already recovered from an Omicron infection can quickly become reinfected. The findings, from Prof Danny Altmann at Imperial College London and colleagues, may help to explain why infection levels have remained high in countries such as the UK, despite so many already having been infected with it.
According to preliminary data from Kei Sato at the University of Tokyo and colleagues, BA.4, BA.5 and BA.2.12.1 may have evolved to refavour infection of lung cells, rather than upper respiratory tract tissue making them more similar to earlier variants, such as Alpha or Delta. The propensity of earlier Omicron variants to prefer infecting non-lung tissue may be one reason why infections tend to be milder in most people. It looks as though these things are switching back to the more dangerous form of infection, so going lower down in the lung, Dr Stephen Griffin, a virologist at the University of Leeds, said.
Satos experiments indicate that BA.4, BA.5 and BA.2.12.1 replicate more efficiently in human lung cells than BA.2, while further experiments in hamsters suggest that BA.4 and BA.5 may cause more severe disease. These variants also appear to have a higher reproduction number than BA.2, while further experiments by Satos lab indicate that BA.4 and BA.5 may be resistant to immunity induced by earlier Omicron infections (similar to Altmanns findings). Altogether, our investigations suggest that the risk of [these] Omicron variants, particularly BA.4 and BA.5, to global health is potentially greater than that of original BA.2, Sato said.

(128,835 posts)At least the combo (bivalent) vaccines look promising but not so much the monovalent Omicron-specific ones though, so expect the bivalents will be the way they go. Gives broader coverage across the variety of circulating variants.
For example, this is what Moderna had presented for the expanded boost their bivalent (original vax + an Omicron-targeted one) provided -
I.e., it worked well not just with the nasty Delta, but the original Omicron and the currently increasing BA.4 & BA.5 variants of Omicron, where the original 1273 by itself (as yet another booster) wasn't doing much to neutralize BA.4 or BA.5.
Ms. Toad
(34,060 posts)It was almost certainly BA.4/BA.5, based on how much of the vaccinated - and largely boosted - group I was with, as well as those two being the dominant strains at the moment.
That booster likely kept my symptoms to a bare minimum (I thought the early symptom was simply a scratchy throat from diving and breathing dry air, and I used no more than 2 dozen tissues for the entire duration of the symptomatic stage - as compared to 2 boxes of tissues for most colds.)
BumRushDaShow
(128,835 posts)for BA.4/BA.5 although the immune response that gets triggered is many times better than what might occur with anyone who is unvaccinated, and even better than that exhibited by those who may have contracted other variants.
And apparently in the trials, monovalent Omicron-specific ones aren't responding as strongly as hoped/expected BUT if done in combo with one of the original vaccines that targeted Wuhan (wild type), Alpha (and even Beta), a nexus of reactive immune responses was found to be achieved. So I expect that will be the direction they will continue to go and it's a matter of finding the proper mix of variant-specific engineered vaccines to achieve the best outcomes.
Hell... these seem to have done better than getting the annual Influenza strains correctly identified, and those vaccines deployed (only to end up with a complete miss like last year or maybe get a 40% hit on the correct one like previous years).
And finally, as is being acknowledged that I yelled 2 years ago - as long as this thing keeps mutating, there is no such thing as "herd immunity" to this and this is finally being admitted (at least tacitly). Although so much more extreme in terms of damage if contracted when compared to the "common cold", COVID-19 is still in the same sort of family as the viruses that cause the "common cold" and there is no "herd immunity" to the "common cold".

(10,901 posts)the latest wave (mostly Ba.4 and .5) in South Africa.
Til the next wave.
BumRushDaShow
(128,835 posts)because South Africa was overrun with the Beta variant where both Europe and the US had very little Beta and mostly Alpha.
Right now, BA.4/BA.5 is swamping the UK and France, where I think I had posted that France had reported they were not quite at peak yet but expected to hit it by the end of this month/beginning of next month.
Fascinatingly enough, BA.4 & BA.5 haven't been accelerating at the extreme rate that the original strains of Omicron did last fall/winter, so although it probably won't drag out like Delta, I don't think it is going to come and go as fast as the original Omicron either.
Don't know if that is an artifact of the drop off of testing to capture a true picture of the presence of it here or what.
So as a comparison - this is how BA.4/BA.5 has manifested as of last week -
And compare with how the dominant BA.1.1.529 of Omicron came blasting in ad shoved Delta completely out of its way -
(edit to add another Omicron BA.1.1.529 in) -
Even BA.2 was running faster than BA.4/BA.5 -

Maybe there is, but no one has informed the British public of that. To be honest, the UK today seems much like the UK of 2019, minus some folks in masks. I mask if I have to go into London by train during rush hour, or unless a business requests it. But that's it.
As it's summer, I haven't done much indoor dining; it's been too nice to be inside.

I was traveling, and ate one meal a day indoors. The rest of the time was outdoors, on an open boat, and/or underwater. (But I was unmasked around my spouse, who was infected earlier - despite testing negative at the time I caught it from her.)
So keep masking!
I am going to mask all the time now.

(56 posts)My first go around was Nov. 2020 and I just found out that I was positive yesterday. I suppose if BA.4 and BA.5 are nationwide then this is what I have. I work in a pediatric hospital so I've been extremely careful. My husband had a "cold" the week before. I've had every symptom except pneumonia and it feels exactly like it did with the OG version. I already have bad parosmia from losing taste and smell the first time and wondering what I'll have an aversion to next.
groundloop
(11,518 posts)I have no way of knowing which strain I caught but assume it's part of the latest wave, and it seems to have been concentrated in my lungs (I'm vaxxed and double boosted). In hindsight I wished I'd have continued to mask when in public, I guess I'd gotten cocky.
It was kind of strange in that I had symptoms for a couple of days and still tested negative. I was pretty miserable for several days, but at the two week mark I'm finally almost symptom free although still testing positive.
I was waiting for my smell and taste to go away, that never happened although at the peak of my symptoms a few things tasted "off".

(4,999 posts)We were on a plane back to the midwest last week, and in prep for that I did more research on face masks. Found the "mask nerd" who actually measured mask filtration function (on his own face).
Anyway, he built up a very large list of masks he tested, including some info about mask size. My SO and I have slightly narrower faces than average, and it was always a struggle to get a good seal around our cheeks.
These Bluna masks were very good, fit us very good, were comfortable for the whole airport/plane trip -- about 7 hours. They are in the top tier of kn94/n95 grade.
Glad we had the masks, as only about 1 in 10 passengers was wearing a mask.

This shows the lineages and why a variant might keep its same name but be sub-numbered vs being considered a distinctly new entity.

They do go and really look at the genetic sequencing in these viruses and probably have criteria of how much of a change (within a variant) and/or what locations and types of sequence differences there needs to be to declare it a standalone.
I.e., its probably similar to how biologists/botanists/entomologists "key out" a species of animal/plant/insect based on certain "traits/characteristics" from the "Kingdom" level down to sub-species (if necessary) to identify an unknown find and determine whether it is unique enough to classify as new (or reclassify after finding it had a known origin that was missed).

Ms. Toad
(34,060 posts)I've been extremely careful for the past 2+ years, but am just past isolation from a COVID infection I picked up while traveling. Out of the 100 people I was traveling with for a week of diving, I have learned after the fact that at least 20 were infected during out time together. (That is the number of people who have 'fessed up, so I suspect the actual number is higher).
I ate one meal a day indoors - and only one of those was near anyone outside of my family, in an otherwise mostly empty dining room. (Perhaps 20% full at the peak - especially after the first day when everyone decided the food was crappy). The rest of our meals were outside (we didn't have an outdoor option for the evening meal). Most of the rest of my time was spent on an open-air boat or underwater. When I was indoors and not actively eating, I was masked.
My spouse, on the other hand . . . didn't mask at all, and spent considerably more time indoors with others since she doesn't dive. And we shared a room.
She had an "allergy attack" mid-week, but tested negative. She has very severe allergies which knock her out sometimes for days at a time. This attack was consistent with several actual allergy attacks she had over the past couple of years and we were unaware of anyone around us was infected, so we assumed it was the same as all of her prior attacks during COVID. She took allergy medication, slept the rest of the day, and had snuffly remnants for a couple of days after that (as usual following an allergy attack). She apparently passed it on to me.
So, unfortunately, both of us traveled home with COVID. Comparing the folks I saw board our flight to the people who announced within 24 hours of getting home that they had contracted COVID - 5 of us were traveling with COVID. 4 of us were unaware of our infections at the time of the travel - large-scale testing was initiated among the group after one of the individuals on my flight announced he had tested positive. We also learned of one jerk who was running a fever on Friday, tested positive Friday, and still hopped on the plane unmasked on Saturday. Of the 5, I was the only one wearing a mask. Perhaps 5% of the others on the plane were wearing masks.
My employee (traveling on a plane the same day, but not with me) got COVID for the second time. My brother traveling in the same time frame was exposed in the airport, and came home with COVID.
All of the group I was with were vaccinated (it was a prerequisite to participation, verified with documentation provided at the time of registration). Most of us had mild cases - but three of the 20 were pretty severe (but still short of hospitalization).
I was relatively asymptomatic (a scratchy throat for a day just after my last day of diving - not uncommon after that many hours of breathing dry air), followed a couple of days later by a bit of coughing and congestion. I am still testing positive, though, 9 days after my scratchy throat.
I'll test again before joinng the family for an outdoor party tomorrow. But the last test was positive as soon as the reagent crossed the "C" line. My brother was positive for 14 days. So I can believe that this variant's superpowers are infection (and reinfection) if that much of the virus remains in the nasal passages long after symptoms are gone.
oldsoftie
(12,530 posts)We just have to learn to live and deal with it. That means different actions for different people. And hopefully future variants will be weaker. We'll also probably end up with more effective vaccines coming soon. I'm done with "boosting" until the new version come out and are shown safe. My wife & I both have had it; probably around January. Only way we knew was my blood donation shown the Reactive+ antibody. So I told my wife to get checked when she had her physical. Shed had the antibodies too. Neither of us ever knew we had it. I credit the vaccines for that.
And yet I STILL to this day have friends who refuse to get one.
