On the occasion of World Malaria Day 2025, medical experts have highlighted a startling fact that many people are unaware of – malaria-causing parasites can quietly hide in a person’s liver for several months without showing any symptoms. This dormant presence can later cause recurring fever and health complications, making malaria more difficult to control and treat.

What Makes Malaria Dangerous?

Malaria is a life-threatening disease caused by Plasmodium parasites, which are transmitted through the bites of infected female Anopheles mosquitoes. While most people associate malaria with high fever, chills, and body aches, the real threat often lies deeper. According to health professionals, certain types of malaria, particularly Plasmodium vivax, can remain inactive in the liver even after the visible symptoms subside.

Dr. Nikhil Sharma, an internal medicine specialist, explains, “People often think they’re cured after initial treatment, but in some cases, the malaria parasite lodges itself in the liver and waits silently. Weeks or even months later, it can reemerge and cause a relapse.”

Why Prevention is the Best Cure

Because of malaria’s ability to lie dormant, it’s important to focus on prevention rather than just treatment. A single bite from an infected mosquito can start the disease cycle. That’s why awareness and proactive protection play a key role in reducing infection rates, especially during the monsoon season when mosquito breeding increases.

“Preventing mosquito bites is far more effective than relying solely on medication,” Dr. Sharma adds. “We must also be alert to recurring symptoms, even after previous episodes of malaria.”

Doctor-Recommended Tips to Prevent Malaria

• Use Mosquito Nets: Always sleep under insecticide-treated nets, especially in high-risk areas.
• Apply Repellent: Use mosquito repellents on exposed skin and clothing, especially during dawn and dusk when mosquitoes are most active.
• Keep Surroundings Clean: Eliminate standing water from flower pots, coolers, buckets, and drains to reduce mosquito breeding.
• Wear Protective Clothing: Long-sleeved shirts and pants help reduce exposure to mosquito bites.
• Install Screens: Fit doors and windows with fine mesh screens to keep mosquitoes out.
• Travel Precautions: If you are traveling to a malaria-prone region, consult your doctor in advance for anti-malarial medication.

Common Symptoms of Malaria

Being alert to early symptoms can help ensure timely diagnosis and treatment. The following signs should not be ignored:

• Sudden high fever
• Chills and shivering
• Headache and fatigue
• Nausea and vomiting
• Muscle pain
• In severe cases, convulsions or unconsciousness

Importance of Timely Testing and Treatment

If malaria is suspected, a blood test is essential to confirm the presence of the parasite. Quick treatment not only cures the illness but also prevents further transmission. Doctors recommend completing the entire course of prescribed medication to ensure the parasite is completely eliminated, including any dormant forms in the liver.

India’s Battle Against Malaria

India has made significant strides in malaria control over the years. However, regions with poor sanitation and water logging remain hotspots. The Ministry of Health and Family Welfare has launched several campaigns to promote mosquito control and encourage people to seek immediate medical help at the first sign of symptoms.

According to the latest government data, urban slums, rural areas, and tribal regions remain most vulnerable due to limited access to healthcare and prevention resources.

A Collective Responsibility

On this World Malaria Day, citizens are urged to play an active role in protecting their communities. From using simple preventive tools like mosquito nets to reporting suspected malaria cases promptly, everyone can contribute to India’s goal of eradicating malaria.

As “We need a mindset change. Malaria is preventable. It’s no longer just a rural disease. Urban dwellers, too, must remain vigilant. Cleanliness, early diagnosis, and continued public health efforts will eventually help us win the fight against this silent enemy.”

Let us use this awareness day as a reminder that health and hygiene are the first lines
