Delta plus variant mystery: What can cause the third Covid wave?

Things in India are looking to normalize and beginning to reopen after a deadly second wave of Covid-19 infections devastated the country in April and May.  There is various thought process from experts who are warning that a third wave could strike in the next few months. The majority of Indians are worried about new variants named delta plus, which is related to the Delta, an existing variant of concern first identified in India last year that was responsible for the deadly second wave.

The million-dollar question is how realistic these fears are. The reality is that future waves are not out of question but their severity and spread depend on several factors. In the past few weeks, the number of average daily cases in India has tapered down to less than 40,000 in recent days which was peak over 420,000 in May. The big drop in numbers has mainly because of strict lockdowns by states.

Many social and political events added to the second wave. If the reopening process are not orchestrated in a controlled fashion the next wave could come sooner than expected.

We are in a very decisive phase and our fate will depend on how we behave. Opening the states in a staggered manner is best. Going aggressive with vaccination and continue with COVID protocols will be the winning strategy. A balanced local and central health protocols could do the magic while severe action on defaulters could be used as a deterrent.

We know that the Delta variant had a killer impact during the second wave. The risk of future mutants in densely populated areas is known and preventive actions should be put in place immediately. There is no clear data around Delta plus but things have changed really fast when the proactive approach is not taken in advance. We need to understand that mutants only emerge when active transmission happening. A lot of research is happening around it take preemptive containment measures by understanding probable sequences.

So far data is indicating that the current vaccine is delivering good results in emerging mutants. India had sequenced 30,000 samples until June, but experts believe more needs to be done because the current vaccine is not a guaranteed long-term solution.

There are multiple cases where vaccinated people have got infected. Some call 3rd wave inevitable and some call it will be a smaller wave but the science is indicating that it will all depend on how effective our existing vaccine is against the new variants.

So, in conclusion, one can say that the key is the vaccinated population in controlling the wave and even allowing it to be formed. The acquired immunity and its efficacy will be crucial in determining the damage the third wave can cause. The required daily dose is upwards of 10 million to get all eligible populations covered by 2021.

The wide range of infection-causing natural antibodies and vaccination combined will provide the ammunition India needs badly to shield against future variants. The problem is the data around it is not very accurate. During the height of infections lot of COVID, infections went unreported. A lot of statisticians around it are guessing the acquired immunity percentage to be around 65%. This number should not be the reason we can take it easy.  

Acquired immunity is immunity you develop over time from a vaccine or exposure to the infection.

Conclusively it can be said that “Third wave is only possible if the new variant beats the barriers of acquired immunity.”

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.
