First detection of XEC in Virginia

By Jean Jadhon

ROANOKE, Va. (WDBJ) - A new COVID-19 variant has been detected in half of U.S. states, including Virginia.

It’s the X.E.C. variant.

Some of the earliest cases were reported from samples tested at the Fralin Biomedical Research Institute at Virginia Tech Carilion in Roanoke.

Carla Finkielstein is the director of the Molecular Diagnostics Laboratory and professor at Virginia Tech’s Fralin Biomedical Research Institute. She oversees the lab where they’re tracking the virus.

“We have detected a new variant that is called XEC,” said Finkieltein. The cases we identified all came from Southwest Virginia.”

But Finkielstein says the virus may not have originated here.

“I want to make sure we don’t link the cases to Southwest Virginia because this could be simply people that traveled to Europe and arrived [back] and they live in Southwest Virginia.

Scientists at the Fralin Biomedical Research Institute at Virginia Tech Carilion in Roanoke have been testing samples since the pandemic began; the tests are completed in the same day in an intricate process.

Here they conduct genomic surveillance, tracking the virus at the molecular level. The idea is to catch any changes in the virus early.

“The reason is you want to catch something that is super new immediately that pops up,” said Finkielstein. “So you can report it to the health department.”

The information is also entered into a federal database.

So far Finkielstein says the new variant doesn’t seem to present in patients much differently than past variants of COVID-19.

“It shows kind of the typical symptoms of COVID we’ve seen before. Maybe this one seems to have a little bit more of a sore throat which is a little different,” said Finkielstein.

The lab tests samples from all over Virginia. Finkielstein predicts a surge in COVID cases this winter and is advising everyone to get their COVID vaccine and to wear a mask if you feel sick out of courtesy to your co-workers and friends and to help prevent the spread of the virus.

WHO press release suggests I was

Meryl Nass Oct 30, 2024 Here is what I wrote last night:

“The WHO never once said what its teams are going to actually do. Or if any doctors or nurses were part of teams. They are not sending in imprecise PCR kits to gin up the cases and deaths, are they?”

And this morning, it looks like that might be exactly the plan:

News Release

WHO lists additional mpox diagnostic tests for emergency use

As part of ongoing efforts to enhance quality-assured testing options, the World Health Organization (WHO) has listed two additional mpox in vitro diagnostics under its Emergency Use Listing (EUL) procedure. WHO’s EUL is based on the review of quality, safety and performance data in compliance with international standards while addressing the specific needs of low- and middle-income countries (LMICs).

Polymerase Chain Reaction (PCR) testing, which detects viral DNA, is considered the gold standard for diagnosing mpox infection.

WHO listed the Xpert Mpox, a real-time PCR test manufactured by Cepheid under its EUL procedure, on 25 October. This test is designed for use on compatible GeneXpert systems. The Xpert Mpox test is easy to operate and delivers results in under 40 minutes. Once the cartridge is placed in the system, the process is fully automated, with real-time PCR detecting viral DNA of monkeypox virus clade II. The GeneXpert system is a near-point-of-care testing option, which can support decentralized testing.

Another PCR-based option, the cobas MPXV assay, developed by Roche Molecular Systems, Inc., was listed on 14 October 2024. It is intended for use on the cobas 6800/8800 Systems. This tool is a real-time PCR test capable of detecting both mpox clades and delivering results in under 2 hours. It can process multiple samples simultaneously and is suitable for clinical laboratories that handle large volumes of tests.

“Ensuring global access to mpox diagnostic tests that meet WHO standards for quality, safety and performance is essential for efficient and effective testing in settings affected by mpox outbreaks,” said Dr Rogerio Gaspar, WHO Director for Regulation and Prequalification. “Rapid access to those listed products is critical not only for prompt diagnosis and timely treatment but also for effectively containing the spread of the virus."

WHO previously listed Alinity m MPXV assay, manufactured by Abbott Molecular Inc. under EUL on 3 October.

@angelofthemornings Making this a proper reply-post because as a reply it might end up being too big.

The field is very vast, but the most common would be the person that runs the tests a physician asks you to and signs the paper to validate the results - we can be found doing your bloodwork, urine, biochem analysis (which all falls under clinical analysis/clinical pathology), and many other fields like radiology (x-rays, tomography, etc), acupuncture, embryology... here in Brazil we can have up to 29 licenses, each one corresponding to a different field. Some of these you can come out of university ready to work due to experience in your internship, but some others will require a specialization course or a master's - like acupuncture and radiology.

My license is in clinical pathology, but I've also spent a year in a specialization/expertise program (after getting my bachelor's degree) in laboratorial surveillance for diseases of public health interest, with a focus on diagnostic tools of immunology (serology tests) and molecular biology (mostly real time Polymerase Chair Reaction - PCR).

So I'm both licensed to work in any hospital or particular lab to run tests (with the objective of a diagnosis), and to work with the government in public health surveillance (where the objective here isn't a diagnosis, it is to confirm cases of a disease in a certain population and keep an eye out on how it behaves throughout the year, epidemiology).

I was about to decide between a Master's or a "direct" Doctorate (a Doctorate that "skips" a Master's and lasts longer than the usual Doctorate program) but then the pandemic came and many internship deals crashed, unless you were in virology, as that became the main and only focus of research at the time. I tried for a spot in the State's Strategic Lab, but it was interview-only and for only 1 candidate - I was placed 4th.

With that, my grandma's health also began to deteriorate, so I've been staying home since then to help care for her.

But 4 years later, I've started to job hunt again, and I'm now afraid I might be overqualified (and thus, "more expensive") to employers, as so far I havent gotten any return from my applications. I quite miss and wish to return to academia, sometimes, and with the State's lab, but I have a love-hate relationship with academia and it takes them forever to open up sign-ins for employees. Working in public health was my best time though, really, so if the opportunity arises, I'll be trying my chance there again - I did leave in good terms, and a lot o the chief researchers there wanted to work with me.

[lizziedoesvetpath]

Hello there! hope you’re doing well, i like the blog :)

Vet field question incoming. I’ve got a bachelors degree in biology and I’ve been doing assistant stuff at a clinic, a lot of on the job training, for the last year.

Just curious what options there are for veterinary pathology or on the more laboratory side of vet things… would all of those positions likely require further studies for me?

Bonus question for fun — what’s your favorite type of sample to examine/read?

Thank you for the questions, I’m glad to hear you’re enjoying my blog! 

Bonus answer for fun: Recently I’ve been really enjoying the challenge of neuropathology cases, so my favorite sample to examine has been brains (insert zombie joke here). Enjoy this histology image of a (normal) brain I looked at recently:

This post is going to get long, so my explanation of some career options is below the cut. I haven’t gone down all these paths myself, so this is accurate to the best of my knowledge, but if something catches your eye I would recommend finding someone to talk to who is actually in one of these roles. Try looking at your local vet school/diagnostic lab for more info. You may also want to try searching for some of these job titles to see what different employers are asking for and what the job descriptions are.

Veterinary pathology/laboratory career options:

There are a lot of ways you can get involved with veterinary pathology/laboratory work, each of which requires varying levels of training. Below is what I know about the job descriptions and qualifications of the various people I work with, but there are definitely more. In particular, I work in anatomic pathology, so I’m not as familiar with the requirements for working in clinical pathology, but I suspect there is significant overlap

1. Veterinary anatomic pathologist: What I’m training for. I perform necropsies and use histopathology on both necropsy and biopsy tissues to diagnose disease. I also look at the results of a range of additional testing (IHC, bacterial culture, PCR, toxicology, and more) and interpret these findings in conjunction with my own to inform a diagnosis and make recommendations.

Training required: Veterinary degree (DVM/VMD/BVSc or similar) + minimum 3 years specialist residency training for board certification. Some roles may prefer a PhD or Masters degree (academia, some industry positions).

Veterinary clinical pathologist: Make diagnoses by interpreting the results of cytology, blood counts, serum biochemistry, urinalysis, flow cytometry, and more. These pathologists also interface with a range of additional diagnostic techniques, like we do in anatomic pathology. 

Training required: Veterinary degree + 1 or more years of internships + minimum 3 years specialist residency training for board certification. Some roles may prefer a PhD or Masters degree

2. Veterinary microbiologist: A veterinarian with additional training in one or more of bacteriology, virology, mycology, and parasitology. These vets work at laboratories and provide specialist advice on microbiological testing and management of infectious disease.

Training required: As above for veterinary pathologist. PhD required for board certification

3. Laboratory assistant: The job title for this one will vary, so check the job descriptions. Veterinary diagnostic labs have a wide range of staff who perform the assays required for diagnostic testing. At the lab where I work there are staff who work in our bacteriology, parasitology, molecular diagnostics (PCR), and aquaculture labs. They set up and interpret cultures, perform fecal floats, run PCR, and more.

Training required: Varies by role. Most require an undergraduate degree, typically in microbiology or similar

4. Histology technician: Similar to a laboratory assistant but these people specifically work on producing slides for histological interpretation. Section/trim and process tissues, make slides, stain slides, and perform IHC. Work closely with pathologists to produce slides of diagnostic quality.

Training required: Undergraduate (bachelor’s) degree in science. Some jobs will require additional certification as a histotechnologist

5. Necropsy technician: Assist on the necropsy floor. Keep supplies stocked, accept and store bodies for necropsy, collect samples and assist with prosections. Depending on where you work, you may be primarily responsible for performing the gross necropsy while supervised by a pathologist who would interpret your findings (this is common in industry positions)

Training required: Varies by position. Qualifications as a laboratory animal technician or degrees in biological sciences may be beneficial.
