Delta Variant: Virus is changing and we need to change too!

The entire world is changing its overall strategy on the coronavirus pandemic this week. Masks are back, vaccine mandates are looming, and officials have sounded more worried than they have in months. Employees must wear a mask throughout the day at work while also keeping distance from others and submitting to a virus test once per week for safety reasons driving these changes as two factors: The large number who remain unvaccinated due to fears about vaccines' health effects combined with Delta variant's rapid spread across Europe over recent weeks which forces authorities around the world into immediate action against disease threat."

The Delta variant, originally known as B.1-617.2 has been around since last year but in recent months it's become the fastest spreading virus of all time according to many experts and scientists who are researching this issue more now than ever before. The US Centers for Disease Control (CDC) have also said that COVID-19 cases have increased over 300% nationally from June 19th to July 23rd along with parallel increases in hospitalizations and deaths are driven by the highly transmissible B: 1 617 2 delta variant which is one of a few reasons why they're so concerned about this new strain because there doesn't seem like any way we can stop or cure it yet if at all.

The Delta variant, originally known as B.1.617.2, has been around since last year but in recent months it's become speedily dominant with an 80% share of newly diagnosed cases across the US according to Centers for Disease Control and Prevention (CDC). The CDC says there have also been "parallel increases" in hospitalizations and deaths which are being driven by this new highly transmissible strain - COVID-19 or what is now better described as the Delta infection

Let's understand what the Delta variant is: a virus that has been around since late last year but in recent months it has become speedily dominant in many countries. It accounts for more than 80% of newly diagnosed cases.

The Delta variant is more transmissible in some studies, but not all. One CDC document indicates the Delta variant to be as contagious as chickenpox with each infected person infecting a few others. This difficult number to check because it requires much testing which has yet been done

The Delta variant is more transmissible than traditional coronavirus, but we don't know by how much. The CDC estimates that the new virus might be about 60-200% as contagious as chickenpox with each infected person infecting eight or nine others on average while a typical case of common cold only has an infection rate of two other people per affected individual. One paragraph from one CDC document indicates that this number could even be higher and since it's difficult to determine exact statistics without comprehensive testing, there are multiple possible outcomes for these estimations.

In a recent presentation, the CDC has noted that vaccines prevent more than 90% of severe diseases but may be less effective at preventing infection or transmission. However, if you're vaccinated with one of two currently approved COVID-19 mRNA vaccine brands (Pfizer and Moderna), then evidence suggests they are highly effective against hospitalization and death for various strains such as Alpha (B.1.1.7) Beta (B 1/351), Gamma( P 1 ), Delta( B/617).

 The presentation notes that vaccines are less effective at preventing infection or transmission and sometimes can lead to breakthrough outbreaks in communities despite vaccination. To help combat these effects, the site also noted Moderna's mRNA COVID-19 vaccine is highly effective for many strains of measles including Alpha (B.1.1), Beta (B2) Gamma (P), Delta B(2).

A recent study has shown that the effectiveness of vaccines against certain variants may be lower than previously anticipated. The CDC is urging for ongoing monitoring to ensure appropriate vaccination strategies are developed and implemented with these new findings in mind.

Data suggest that the vaccine is less effective against confirmed infection and symptomatic disease caused by variants of influenza. Ongoing monitoring should be done to ensure that vaccines are still as effective in fighting off Delta variant though lab tests indicate immune response generated should cover it.

Delta has a unique set of mutations that may allow it to evade the human immune system and be more efficient in infecting cells. Delta's changes are limited to its receptor-binding domain, which allows for tight connections with the host cell while also helping this virus escape detection by hiding from our body's natural defenses like antibodies. One change is believed to help make these bonds tighter--making us sicker faster!

The delta virus has at least three mutations on a structure that is called the receptor-binding domain--the part of the disease-causing agent responsible for docking into human cells it infects. It may help evade detection by our immune system, and one mutation, in particular, could make it bind more tightly to infected cells.

National Dentist Day 2025

National Dentist Day: Best Oral Hygiene Tips Shared by Experts

Every year, on March 6th, National Dentist Day is celebrated to recognize the invaluable contributions of dentists in maintaining our oral health. This special day also serves as a reminder of the importance of good oral hygiene habits. Whether you're looking to improve your daily dental routine or seeking expert advice, we’ve compiled the best oral hygiene tips shared by dentists to help you achieve a healthy and confident smile.

1. Brush Properly, Not Just Regularly

Brushing twice a day is essential, but how you brush matters just as much as how often. Experts recommend using a soft-bristled toothbrush and fluoride toothpaste. Follow these steps for effective brushing:

  • Use a gentle, circular motion rather than scrubbing.

  • Brush for at least two minutes twice a day.

  • Ensure you clean all tooth surfaces, including the back molars and gum line.

2. Flossing is Non-Negotiable

Flossing removes food particles and plaque from between your teeth where your toothbrush can’t reach. Dentists suggest flossing at least once a day to prevent cavities and gum disease. If traditional flossing is difficult, consider using:

  • Water flossers

  • Interdental brushes

  • Floss picks

3. Rinse with Mouthwash for Extra Protection

Using an antibacterial mouthwash helps reduce plaque, prevents bad breath, and protects against gum disease. Look for a fluoride-based or alcohol-free mouthwash, especially if you have sensitive gums.

Tip: Rinse for 30 seconds after brushing and flossing for best results.

4. Eat a Tooth-Friendly Diet

What you eat significantly impacts your oral health. Dentists recommend incorporating the following foods into your diet:

  • Dairy products (milk, cheese, yogurt) to strengthen enamel.

  • Crunchy fruits and vegetables (apples, carrots) to naturally clean teeth.

  • Nuts and seeds for essential minerals like calcium and phosphorus.

  • Green tea for its antibacterial properties.

Avoid excessive consumption of sugary snacks, acidic beverages, and sticky candies, which can erode enamel and lead to cavities.

5. Stay Hydrated and Limit Sugary Drinks

Drinking plenty of water helps wash away food particles and bacteria, keeping your mouth fresh and clean. Limit soda, sports drinks, and coffee, as they can stain teeth and contribute to decay.

Pro Tip: If you drink sugary or acidic beverages, use a straw to minimize direct contact with your teeth.

6. Replace Your Toothbrush Regularly

A worn-out toothbrush is ineffective at cleaning your teeth. Dentists recommend replacing your toothbrush every 3-4 months or sooner if the bristles are frayed. Using an electric toothbrush can also improve plaque removal.

7. Schedule Regular Dental Checkups

No matter how diligent your oral hygiene routine is, visiting your dentist every six months is crucial for professional cleanings and early detection of dental issues. Regular checkups can help prevent cavities, gum disease, and even serious health conditions linked to poor oral health.

8. Protect Your Teeth While Playing Sports

If you engage in contact sports, wearing a custom-fitted mouthguard can protect your teeth from injuries and fractures. This simple preventive measure can save you from costly dental treatments.

9. Avoid Smoking and Tobacco Products

Smoking and tobacco use are major contributors to gum disease, tooth loss, and oral cancer. If you’re looking for another reason to quit, your oral health is a great motivation. Talk to your dentist about resources to help you quit.

10. Teach Kids Good Oral Hygiene Habits Early

Children should learn proper oral hygiene habits from a young age. Encourage them to:

  • Brush their teeth with fluoride toothpaste.

  • Floss regularly.

  • Visit the dentist every six months.

  • Avoid excessive sweets and sugary drinks.

Setting a strong foundation for oral health can prevent future dental issues and ensure a lifetime of healthy smiles.

Conclusion

This National Dentist Day, take the opportunity to improve your oral care routine by following these expert tips. Good oral hygiene isn’t just about having a bright smile—it’s also essential for overall health and well-being. Show appreciation for your dentist by prioritizing your dental health and scheduling your next checkup.
