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.

How Poor Hydration Affects Joint Health: Why Water Matters for Mobility

Water is essential for nearly every function in the human body, yet many people underestimate its importance for joint health. While hydration is commonly associated with digestion and skin health, it also plays a crucial role in maintaining smooth and pain-free joint movement.

Understanding how poor hydration affects joint health can help prevent stiffness, discomfort and long-term mobility issues.

The Role of Water in Joint Function

Joints are where two bones meet, allowing movement and flexibility. Healthy joints rely on:

Cartilage
Synovial fluid
Ligaments
Tendons

Cartilage, which cushions bones, contains a high percentage of water. Synovial fluid acts as a lubricant, reducing friction during movement.

Proper hydration ensures these components function effectively.

What Happens When You Are Dehydrated?

When the body lacks sufficient water:

Synovial fluid production may decrease
Cartilage may lose elasticity
Joint cushioning becomes less effective

This can result in stiffness and discomfort.

1. Reduced Joint Lubrication

Synovial fluid requires adequate hydration to maintain volume and viscosity.

Without enough water:

Friction between bones increases
Movement becomes less smooth
Risk of wear and tear rises

2. Increased Joint Stiffness

Dehydration may cause joints to feel tight, especially:

In the morning
After prolonged sitting
During physical activity

Stiffness may limit flexibility.

3. Higher Risk of Injury

Poorly lubricated joints may be more prone to:

Sprains
Strains
Cartilage damage

Hydration supports tissue resilience.

4. Worsening of Existing Joint Conditions

Individuals with conditions such as osteoarthritis may experience increased discomfort if hydration is inadequate.

While water does not cure arthritis, it supports overall joint function.

5. Reduced Nutrient Delivery

Water helps transport nutrients to joint tissues.

Dehydration may impair circulation and nutrient exchange, slowing tissue repair.

Signs of Dehydration That May Affect Joints

Dry mouth
Dark urine
Fatigue
Headaches
Muscle cramps
Joint stiffness

Recognizing early dehydration signs prevents complications.

How Much Water Do You Need?

Hydration needs vary depending on:

Body weight
Climate
Physical activity level
Health conditions

On average, adults may require 2–3 liters of water daily.

In hot climates such as India, higher intake may be necessary due to increased sweating.

Tips to Maintain Proper Hydration

1. Drink Water Regularly

Do not wait until you feel thirsty.

2. Eat Water-Rich Foods

Include:

Cucumbers
Watermelon
Oranges
Tomatoes

3. Limit Excessive Caffeine and Alcohol

These may contribute to fluid loss.

4. Carry a Water Bottle

Keeping water accessible encourages consistent intake.

5. Hydrate Before and After Exercise

Physical activity increases fluid loss through sweat.

Hydration and Joint Health in India

In India’s hot and humid climate, dehydration is common, especially during summer months.

Outdoor workers, athletes and elderly individuals are particularly vulnerable.

Maintaining adequate hydration supports not only joint health but overall wellbeing.

When to Consult a Doctor

Seek medical advice if you experience:

Persistent joint pain
Swelling
Limited range of motion
Redness or warmth around joints

These may indicate underlying joint disorders requiring evaluation.

Conclusion

Poor hydration can negatively affect joint health by reducing lubrication, increasing stiffness and raising injury risk. Since cartilage and synovial fluid depend heavily on water, maintaining adequate hydration is essential for smooth movement and long-term mobility.

Drinking sufficient water daily is a simple yet powerful step toward protecting joint health. Combined with regular exercise and balanced nutrition, proper hydration supports active and pain-free living.

Small daily hydration habits can make a significant difference in how your joints feel and function.
