COVID associated Black Fungus: What you need to know

As COVID spreads across India, there has been an increase in reports of associated infection with a black fungus occurring in some patients. It affects the nose, mouth, eyes, and lungs, and can be fatal. This is an infection we need to be educated on, and early recognition of it can be life-saving. Today we will talk about Mucormycosis, the black fungus responsible for these infections, and what you should do to prevent or recognize an infection.

If you want to learn how to recognize the infection, go down to the INFECTION section of the article.

FUNGUS

When our body gets infected by a bacteria or virus, the signs and symptoms are often recognized early because bacteria and viruses are aggressive, with toxins and mechanisms designed to cause harm to our body and cause easily recognizable symptoms. Fungi on the other hand are slow-growing, and usually, our bodies can fight usually fight these infections before they become a problem. We breathe in fungal spores all the time, especially when outside, in the garden, or in fields, and they cause no harm.

Mucormycosis, the responsible fungus, is found in soil, and decaying fruits and vegetables. It can enter our body by inhalation, by eating foods infected with it, or by direct contact with an open wound, thereby entering our blood. It can be found inside the nose of healthy people, causing no problems or disease. Before the COVID pandemic, infection by mucormycosis was up to 80 times more prevalent in India than in other developed countries, though still rare.

IMMUNOSUPPRESSION

Looking at case reports of patients infected with mucormycosis shows a common theme. Immunocompromised patients are at much higher risk of infection by the fungus and are more likely to have severe disease. This includes patients with diabetes, poorly controlled diabetes, patients taking steroids, organ transplant patients (who are usually on immunosuppressive medications to prevent rejection), those with blood cancer (leukemia/lymphoma, reducing your blood immunity).

Diabetes (especially poorly controlled diabetes) is a major problem in these cases, as diabetes is fairly common in India, can lay unrecognized, and if not controlled or treated appropriately the rising blood sugar levels can damage your arteries, nerves, and significantly lower your immunity. Any infection in diabetic patients can be more difficult to treat and spread more quickly, and this is made worse by COVID-19.

COVID causes widespread inflammation throughout the body, especially the lungs, and the resulting damage causes difficulty breathing and death by respiratory failure. Steroids are currently our best way to treat COVID, by suppressing the body’s immune system and preventing lung damage. Unfortunately, this also allows mucormycosis spores inhaled by COVID patients to infect the now vulnerable, damaged airway, lungs, and sinuses, and start spreading. The body’s response to the infection is dampened by the steroids, and in those with diabetes, it is hindered further.

INFECTION

The black fungus usually spreads in the nose and sinuses of the skull, as it prefers a warm, humid environment. From here it can spread into the eyes and in rare cases the brain.

Recognize the symptoms of the fungus, and be very suspicious in patients with diabetes or those who have had high doses of steroids.

- Facial swelling on one side

- Nose or sinus congestion

- Pain in the sinuses, around the nose, and eyes

- Black mold growing around the nose or mouth

- Fever, headache

When it infects the lungs it can cause symptoms such as cough, shortness of breath, or chest pain. Unfortunately, this can be difficult to separate from symptoms of COVID infection.

If you suspect you or someone you know has these symptoms, and they have the risk factors of immunosuppression or diabetes, you should visit a doctor early. Mucormycosis has a high mortality rate, and a delay in diagnosis by even a week can double it. Your doctor will take swab samples from your nose and look for signs of the fungus under a microscope. Blood tests and scans are also helpful in identifying the fungal infection.

TREATMENT AND PREVENTION

Treatment of mucormycosis requires IV antifungals such as Amphotericin B and may involve surgery to remove the infected areas and prevent further spread. This can include surgery in and around the nose, sinuses, and in rare cases even the eyes. This all depends on the extent of the fungal infection.

Prevention is key in these cases. Simple measures such as wearing a mask to reduce inhalation of spores can minimize infection, especially in the vulnerable, though it may not prevent it if they already had spores present in their nose and sinuses. Glucose tests to look for diabetes, and strict control of diabetes will improve your chances significantly. Keeping your blood sugar levels within the normal range is very important, so if you are diabetic now is the time to stick to your diabetic diet and medications.

Finally, we need to be careful when using immunosuppressive medications to treat COVID, and determining which patients should receive steroids (dexamethasone, prednisolone) and other drugs such as tocilizumab. If you are young and healthy, or you have a milder infection of COVID-19, it may be better for you to not take steroids early. Those with more serious COVID-19 infections may need steroids to survive, and in these cases frequent checks for mucormycosis infection is advisable.

The rise in this rare fungal disease in patients with COVID-19 presents a problem, as we do not have much literature to base our recommendations on, the disease is slow-growing and can be difficult to treat. But as always, understanding the disease process for black fungus and knowing its symptoms is important, as is informing your family and friends about this disease.

5K Run for a Cause: How Community Fitness Drives Preventive Health Awareness

5K Run for a Cause: How Community Fitness Drives Preventive Health Awareness

Physical activity is one of the most effective tools for disease prevention, yet it remains underutilised in everyday life. Community-based fitness initiatives such as a 5K Run for a Cause play a powerful role in bridging this gap by making movement accessible, meaningful and socially engaging. These events combine the benefits of exercise with awareness-building, creating lasting impact on public health.

In India, lifestyle-related diseases such as diabetes, heart disease and obesity are rising rapidly. According to the Indian Council of Medical Research (ICMR) and National Family Health Survey (NFHS-5), physical inactivity is a major contributor to this growing burden. Events that encourage structured, enjoyable physical activity help counter this trend.

 

What Is a 5K Run for a Cause?

A 5K Run for a Cause is a short-distance running or walking event designed to promote fitness while supporting a health, social or community objective. Participants may run, jog or walk the 5-kilometre distance, making the event inclusive for people of varying fitness levels.

Beyond physical activity, these runs aim to:

  • raise awareness about preventive health
     

  • encourage active lifestyles
     

  • build community participation
     

  • support wellness-driven causes
     

 

Why 5K Is an Ideal Distance

The 5-kilometre distance is widely recognised as:

  • achievable for beginners
     

  • challenging enough to promote fitness
     

  • safe for most age groups with minimal training
     

WHO physical activity guidelines support moderate-intensity exercise like running or brisk walking for improving cardiovascular and metabolic health.

 

Health Benefits of Participating in a 5K Run

Improved Cardiovascular Health

Running and brisk walking strengthen the heart, improve circulation and lower blood pressure. Regular participation reduces the risk of heart disease and stroke.

 

Better Metabolic Health

Physical activity improves insulin sensitivity and supports weight management. ICMR data shows that regular movement significantly reduces diabetes risk.

 

Enhanced Mental Wellbeing

Exercise releases endorphins that reduce stress, anxiety and depression. Community runs add a social element that further supports mental health.

 

Improved Musculoskeletal Strength

Running strengthens muscles, bones and joints, reducing the risk of age-related mobility issues.

 

Role of 5K Runs in Preventive Healthcare

Preventive healthcare focuses on reducing disease risk before illness develops. A 5K Run for a Cause supports prevention by:

  • promoting physical activity
     

  • encouraging regular movement habits
     

  • raising awareness about lifestyle diseases
     

  • motivating health-conscious behaviour
     

NITI Aayog identifies physical activity promotion as a key pillar of preventive healthcare in India.

 

Community Impact of a 5K Run for a Cause

Building Health Awareness

Runs often highlight specific causes such as heart health, diabetes prevention or mental wellbeing, reinforcing public health messages.

Strengthening Social Bonds

Community participation fosters shared goals and mutual motivation, increasing long-term adherence to healthy habits.

Encouraging Family Participation

Inclusive events encourage families to adopt healthier lifestyles together.

 

5K Runs and Corporate Wellness Programs

Corporate wellness programs increasingly include physical activity initiatives.

Benefits for organisations include:

  • improved employee engagement
     

  • reduced absenteeism
     

  • enhanced team bonding
     

  • positive employer branding
     

EY-FICCI reports show that wellness initiatives focused on physical activity deliver strong participation and measurable health benefits.

 

Accessibility and Inclusivity

A key strength of 5K runs is inclusivity.

They accommodate:

  • first-time runners
     

  • walkers
     

  • older adults
     

  • people transitioning to active lifestyles
     

This inclusiveness reduces barriers to participation.

 

Supporting Long-Term Behaviour Change

One-time events create awareness, but their true value lies in inspiring long-term change.

Participants often:

  • continue walking or running regularly
     

  • become more conscious of fitness
     

  • seek preventive health checkups
     

Lancet studies indicate that community-based physical activity initiatives can influence long-term health behaviours.

 

Safety and Health Considerations

For safe participation:

  • individuals should assess fitness levels
     

  • warm-up and cool-down are essential
     

  • hydration should be prioritised
     

  • those with medical conditions should seek medical advice
     

Proper guidance ensures benefits without injury.

 

Role of Awareness and Education

Successful runs integrate education through:

  • health talks
     

  • informational materials
     

  • screening camps
     

  • wellness resources
     

This combination reinforces preventive health messages.

 

Measuring Impact

Impact can be assessed through:

  • participation rates
     

  • follow-up health initiatives
     

  • employee engagement metrics
     

  • community feedback
     

Data-driven evaluation improves future program design.

 

Why 5K Runs Matter in India

India faces challenges such as:

  • rising sedentary lifestyles
     

  • limited health awareness
     

  • increasing chronic disease burden
     

Community fitness events provide a scalable, low-cost solution to promote active living and prevention.

 

Conclusion

A 5K Run for a Cause is more than a fitness event—it is a preventive health movement. By combining physical activity with purpose, these runs encourage healthier lifestyles, strengthen community bonds and raise awareness about long-term wellbeing. In a country where lifestyle diseases are growing rapidly, initiatives that make movement accessible and meaningful are essential. A simple 5K run can be a powerful step toward a healthier, more active society.
