COVID-19: Boosters, Variants, and Precautions To Take

A computer generated image of a virus that looks like a coral reef.

After a summer reprieve, COVID-19 cases are on the rise again. Here’s what you need to know heading into the fall, including a look at the latest variants and upcoming boosters. 


With school back in session and the fall flu season fast approaching, it’s more important than ever to be prepared for a new wave of COVID-19 infections. 



Since people with diabetes are at greater risk of severe complications from COVID-19, it’s extra important to stay on top of the latest research, know your risk, and what to do about it. 


Emerging Omnicron variants 


It seems like every month there's a new COVID-19 variant, which can make things a little hard to keep up with. Earlier this year, new variants of Omnicron dubbed FLiRT strains were identified, accounting for the majority of COVID-19 infections this summer in the U.S.


KP.2, KP.2.3, KP.3, and KP.3.1.1 are all types of FLiRT variants circulating right now. KP.3.1.1 appears to be the most dominant, accounting for roughly 37% of new COVID-19 cases in the U.S. Another strain that also emerged this summer is LB.1, which is not a FLiRT variant but similar.


Last summer, the most dominant COVID-19 strains were Eris (EG.5) and Pirola (BA.2.86). While all these new strains sound alarming, it's natural for viruses to mutate, and COVID-19 is no different. 


The good news is that all these mutations don't necessarily cause more severe infections, but certain strains could transmit faster or be better at dodging the body's immune response after infection. Researchers are working hard to understand what this means for prevention, vaccination, and treatment. 


The CDC and WHO are monitoring variants closely; check out the CDC's COVID Data Tracker to keep up with the latest variants.


 

What does the latest research say about COVID-19 and diabetes? 


Since the early days of the pandemic, diabetes, obesity, and other chronic health conditions have been linked to more severe COVID-19 infections. Age is also an important risk factor to consider.


“COVID-19 can still be serious, particularly in seniors,” said Dr. Anne Peters, professor of medicine at the Keck School of Medicine of USC and director of the USC Clinical Diabetes Programs. 


“My personal sense of the biggest risk factors (in order of risk) are age, immunosuppression, obesity, and poorly managed diabetes,” said Peters. “And then, somewhere on the list, are other comorbidities like kidney failure and heart disease. If someone falls into a higher risk category I still say be careful, even though I want people to live their lives.” 


2023 large-scale analysis found that certain factors were linked to death from COVID-19 among people with diabetes. These include higher blood glucose at hospital admission, long-term insulin use, and other conditions like heart and kidney disease. Additional research demonstrates that high blood sugar (hyperglycemia) at hospital admission is linked to worse COVID-19 outcomes. 


On a more positive note, a 2021 study suggested that the use of diabetes technology was associated with a reduced risk of adverse outcomes among people with type 1 diabetes who have COVID-19. In addition, people taking diabetes and weight loss medications like metformin and semaglutide (Ozempic and Wegovy) may have less risk of severe complications and death from COVID-19.



When should you get your next booster? 


Overall, it’s a good idea to take precautions – like getting a booster – especially if you or your loved ones are at higher risk of complications from COVID-19.


The CDC recommends that everyone aged 6 months and older receive an updated COVID-19 vaccine to protect against the effects of the virus. Updated boosters will be available from Moderna and Pfizer-BioNTech. 


You can get a booster anytime, but some experts suggest that people wait until later in the fall to maximize its protective effects. Waiting to receive the booster will ensure that it targets the variants currently affecting the population. This way, the vaccine will have a better chance of preventing infection as well as severe illness. 


If you receive your booster later in the fall, it should also ensure that you are protected when infections are predicted to spike during December and January (booster shots typically take three months to reach full effectiveness). This coincides with the holiday travel season, so you can visit loved ones safely knowing that you’re protected.

What other precautions should you take? 


People at high risk of severe illness from COVID-19 may want to take additional steps to protect themselves against infection. If you’re worried about COVID-19, experts recommend the following precautions


  • Wear a high-quality, well-fitting mask in crowded indoor areas including public transportation, airports, and concerts
  • Avoid large crowds
  • Choose outdoor dining and activities over indoor spaces
  • Make sure rooms in your house, workspace, or school have good airflow
  • Take a rapid test if you experience any symptoms and before visiting friends or family who are at high risk of developing complications


During this time, it’s also important to continue taking care of yourself and your diabetes. 



“COVID-19 made us all realize how vulnerable we can be,” said Peters. “It is why all the good healthy behaviors we promote – healthy diet, exercise, and treating health conditions like diabetes and hypertension – matter so much. There is a lot we can do to be healthy, even with COVID-19.”

This is like a cross between an unfussy lasagna and a baked ziti: Cheesy, rich, and deeply satisfying, despite the actual absence of noodles. Even my daughter, who tends to be totally skeptical about “fake vegetable pasta dishes,” loves it. Don’t be daunted by the ribboning of the zucchini with a vegetable peeler: It honestly doesn’t take that long, and the resulting strands are thinner and wider and just generally more noodle-like than what you’d get with a spiralizer. That said, if you want to start with a pound of zoodles, go ahead – just be sure to salt and drain them really well or the resulting dish will be watery. One last thing: If you’d prefer a meat sauce, go ahead and brown a pound of ground beef after you sauté the onions and before you add the tomatoes – and expect the dish to feed more people that way. Makes: 8 servings Total carbohydrates: 15 grams per serving Active Time: 50 minutes Total Time: 1 ½ hours Ingredients 3 medium-sized zucchinis (around 1 pound) 2 teaspoons kosher salt (or 1 teaspoon table salt), divided, plus more as needed ¼ cup olive oil 1 onion, finely chopped 3 cloves garlic, finely chopped (or 1 teaspoon garlic powder) 1 (28-ounce) can tomato purée or crushed tomatoes Black pepper 1 (16-ounce) container whole-milk ricotta ½ cup heavy cream ½ cup grated Parmesan ¼ teaspoon nutmeg 1 pound whole-milk mozzarella, grated, sliced, or diced Instructions

Type 2 diabetes, a condition marked by chronically high blood sugar levels, is a leading driver of metabolic disease in America. While conventional medical advice recommends taking medications to control blood sugar levels, this is only a temporary measure at best.  Diabetes is compounded by several factors, and recent research notes that nutritional deficiencies is a commonly overlooked aspect, and that when these deficiencies are addressed, managing and controlling this disease becomes easier.

Telemedicine can make diabetes care less expensive and easier to access, but it may not always be a suitable replacement for an in-person visit. Learn what happens during a telehealth visit and see if you could benefit from using telemedicine for your diabetes care. The pandemic upended a lot about life as we knew it. Notably, it was responsible for a 63-fold increase in telehealth visits . For people managing diabetes, however, having a doctor visit over video brings up a host of questions and potential issues. How can a doctor properly check my eyes and feet through a computer screen? Will telehealth replace in-person discussions about my blood sugar? Will I get the same level of care through a computer? According to a 2022 article in American Family Physician , telehealth is promising for diabetes treatment and has been shown to help improve glucose management. In a separate analysis of glucose data from people with type 2 diabetes, people who received remote monitoring of their glucose levels saw significant improvements in A1C over a period of three months. That being said, no study or physician is implying that telehealth fully replaces in-person medical care for diabetes. Here’s what to consider and who might be the best candidates for telediabetes care. What happens during a diabetes telehealth visit? Telediabetes care involves two types of interactions. One is a video meeting with a physician or care team to discuss challenges and potential solutions. During this type of visit, the healthcare provider can see some physical signs or changes, such as rashes or wounds. The second type of interaction is virtual monitoring of glucose levels through a monitoring device that sends data to the care provider. The provider might also follow up with a video call to discuss the data. “Many of the things that are important for diabetes care – blood glucose data review, medication review, insulin teaching – can all happen over video,” said Dr. Varsha Vimalananda, an endocrinologist and associate professor of medicine at Boston University. “CGM data can be uploaded and reviewed remotely, which is also very helpful.” Different providers use different video platforms for telehealth appointments, but most will look and function much like a Zoom call. The benefits of telehealth in diabetes care Not all elements of diabetes care are best suited for telehealth, but many lend themselves naturally to the conversation and convenience that an electronic visit facilitates. For type 2 diabetes in particular, telehealth has been shown to be more effective than in-person care at helping people manage their condition. One reason for the improved outcomes is simply better access to care. Dr. Keta Pandit, an endocrinologist at Texas Diabetes & Endocrinology in Austin, Texas, says continuous glucose monitoring (CGM), along with telehealth options, have changed the landscape of diabetes care. “One of the benefits of being able to offer telemedicine to our patient population is that it has increased the access to care, especially with any ongoing illnesses, hospitalizations, COVID, post-COVID, or any other situations when patients notice their glucose levels are going out of their standard range. Patients often contact us for these types of situations, and we can quickly get them seen via telemedicine to make adjustments to their diabetes medications,” she says. “While this was still an option prior to telemedicine days, the opportunity to see their provider on short notice, not having to worry about transportation, and not having to put in advance notice to take time off of work to travel to the doctor’s office, are some of the ways access to care has increased.” Pandit says this is particularly true for older patients who require frequent visits and women who are pregnant, as well as those who need to optimize their glucose levels before and after surgery. Jasmine Meidas, 51, of Cleveland, Ohio, is one such patient. She was diagnosed with type 2 diabetes 15 years ago. “During the COVID-19 pandemic, I was much more comfortable with telehealth than going into my endocrinologist’s office, which is in a hospital. I still am,” she says. Meidas has a one-hour telehealth visit every three months. “They can order blood work to be taken locally, [and] we review [the results] together. We also review food choices, lifestyle challenges, stressors, and more. We set action steps and goals for the next 90 days,” she says. Meidas periodically sees her endocrinologist in person as well. At Vimalananda’s clinic in Boston, specific groups are making great strides with telehealth options. “Veterans, mostly,” she says. “I have a few [Veteran patients] who have severe [post-traumatic stress disorder]. Driving out to the clinic, dealing with traffic, and navigating the hospital are all things that cause a lot of distress. It’s been a game-changer for them to be able to have the visit from home.” When is telehealth not the best option? “If you have diabetes, please remove your socks and shoes.” This type of sign is frequently displayed in doctors’ offices. How would a foot exam work in telehealth? This is a real concern for people with diabetes, as up to 15% of patients will have a foot ulcer in their lifetime. Pandit and other experts acknowledge the limitations telehealth can have. “The medical team [must depend] on the patient [to provide] data and limited access to other parameters that are needed, including blood pressure measurements or foot examinations. When visits are conducted via telemedicine…care is not as comprehensive,” says Pandit. “There are times when the telemedicine model may pose risks. The limitation is clearly noted in visits with patients who are not technologically savvy, may have hearing issues, or [have] poor [internet] connection at the time of the visit.” Telehealth can also give health care providers a direct view into the home environment, which may result in a patient’s hesitancy to share openly — with family members potentially nearby — and impede the building of relationships and rapport. For these reasons, Pandit recommends that at least every other visit be conducted in person.

Key takeaways The FDA has issued a warning to users of continuous glucose monitors after reports of missed urgent blood sugar alarms on smartphones. Free apps can act as a backup for CGM alerts on your phone. A secondary alert system, like a CGM receiver or the SugarPixel standalone display, can ensure critical alerts are noticed. The FDA recently issued a safety notice after receiving reports from CGM users who missed critical low and high blood sugar alerts on their smartphones. Some of the causes for the missed alerts included: changes to phone settings, operating system upgrades, and using Bluetooth accessories. The safety warning coincided with my own experience. Following an update to my smartphone, I missed two critical low blood sugar alerts during the night. After missing those notices, I realized that I could back up my CGM alarms the same way I back up photos on my phone or laptop's hard drive. I then went about researching and testing other backup options, including these apps and devices I now use to make sure alarms are heard consistently, especially at night.

Marcia Kadanoff, who lives with type 2 diabetes, shares her top five tips for enjoying a Valentine’s Day meal out. Pink and red hearts everywhere, overpriced dinners, wondering if you’ll have a date (or if you got your partner an appropriate gift) – ah, the joys of Valentine’s Day. I’m stressed just thinking about it. As a person with diabetes, my stress may be a bit different than general Valentine’s Day anxiety. By this point, my spouse knows enough not to get me chocolates, my biggest landmine food. But the hard thing for Valentine's Day or any other romantic occasion is getting a reservation at the right kind of restaurant and – as always when living with diabetes – planning out my meal. Special occasion meals take special skills to navigate. The good news is that there are definitely strategies that can help make a romantic dinner somewhere special enjoyable without diabetes taking center stage. Where I live – the San Francisco Bay Area – many restaurants have Valentine’s Day dinner specials that consist of three to five courses. There’s nothing wrong with eating a multi-course meal, but it does make diabetes management more difficult. From bread to creamy soups and crouton-laden salads to heavy entrées to a dessert that’s potentially cake-filled, multi-course meals can quickly add up to a large amount of carbohydrates, which is a major driver of high blood sugars. The reality is that even if I choose the “healthier” set menu for a celebratory multi-course meal, I still make a point to think about what each portion is bringing (quite literally) to the table. Here are my best tips for navigating a Valentine's Day dinner out.
