Problems With Detecting The Novel Coronavirus (COVID-19) (1)

The Novel Coronavirus Disease has been in the public eye for almost two months now, and a lot has been happening behind the scenes to understand this new outbreak. Several organizations have been working together with the World Health Organization and Officials from China to understand the symptoms and how the virus causes the disease, track the number of people infected by the virus and put in place public health measures to adequately mitigate the potential dangers this disease can bring with it. In this post we will discuss the new updates to the Coronavirus Disease 2019 (COVID-19).

IDENTIFYING COVID-19

As of 17 February, there have been 70, 365 confirmed cases of COVID-19 in China, with 1772 deaths, which gives it an estimated fatality rate of 2.5%. Now whilst these are official figures, the actual estimate may differ from this. This is because the areas that have been heavily affected especially the Hubei region, have had shortages of coronavirus testing kits, with demands far outstripping supply. Testing is required to not only identify patients for treatment but also for isolation and quarantine. This is a key step in preventing the rapid spread of disease amongst the population. Understanding the spread of a new disease also helps scientists create accurate disease models that can determine the infectivity, morbidity and mortality of COVID-19, and predict where the infection may strike next. The government authorities can use this information to prepare the surrounding regions, and ensure the impact of the disease is lessened.

Current testing requires swabs to be taken from the patients mouth and throat. This sample is then sent to laboratories, where the viral DNA is replicated in order to identify whether this DNA is from the coronavirus. Unfortunately, this is expensive, uses lots of reagents and can take two days. Even with laboratories working round the clock, running 6,000 tests a day, the workload is outstripping the health departments capacity. This leaves a large population of the Hubei Province with symptoms suggestive of COVID-19 but with no way to formally diagnose the disease. There may be a significant under-reporting of cases simply because capacity does not exist to test everyone, and the disease burden may be considerably higher.

INNOVATION IN RESPONSE

In response to this doctors have started using CT scans to identify potentially infected patients. CT scans are a quick, non-invasive and readily available. By looking for lesions and signs of pneumonia in the patients lungs. Whilst this negates the need for testing strips, lesions are a fairly late sign of COVID-19, and so this method is not suitable for those who have recently been infected or have not yet shown these symptoms. In the Hubei Province however, with the drastic shortage of testing kits, clinical and radiological diagnosis is now being used to increase the rate of detection.

Manufacturers are also struggling to increase output of testing kits and reagents to match this demand, and the race is on to develop new rapid testing kits. Beijing has approved seven Biopharmaceutical companies to push forward with fast track development of testing kits. Liferiver, a Shanghai based biotech company, took just 20 days from development of its kit to launch. This process normally takes 3 years. China’s Nankai University announced on Monday a breakthrough in developing a rapid test kit that can identify infection among suspected patients within 15 minutes.

And it’s not just Chinese companies — a Singapore based biotech company has announced a portable kit that can detect the novel coronavirus as well as similar viruses responsible for MERS and SARS in a single 2 hour test. These innovations represent a massive step forward in identifying infected patients early in order to provide them the necessary treatment, and in accurately tracking the spread of the disease.

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.
