Importance of Early Diagnosis in Malaria Treatment

By Dr. Rajinder Kumar Singal in Internal Medicine

Oct 22 , 2025 | 6 min read

In many parts of India, malaria still shows up year after year, especially after the rains. It’s not something most people think of right away when they get a fever. Often, people assume it’s a viral infection or maybe just weakness, but that delay in getting checked can make a simple infection worse.

Early diagnosis is critical for malaria treatment because it significantly reduces the risk of severe illness and death, improves the effectiveness of medications, and prevents the spread of the disease to other people by quickly stopping the transmission cycle. Prompt testing also allows for correct treatment selection for the specific parasite type, preventing unnecessary or ineffective treatment and helping to control the emergence of drug-resistant malaria.


Understanding Malaria and Its Symptoms

Malaria is a serious illness caused by the Plasmodium parasite, which enters the body through the bite of a female Anopheles mosquito. The parasite infects the blood, affecting the liver and red blood cells. In India, the most common types are Plasmodium vivax and Plasmodium falciparum. Mosquitoes that carry malaria typically bite at night, increasing the risk for those who live in areas prone to mosquitoes and do not use protective measures such as nets or repellents.

In the early stages, malaria can resemble the flu or a viral fever, making it easy to overlook. Common symptoms include fever with chills, sweating after the fever subsides, headache, nausea, and extreme fatigue. Many individuals try to rest, but malaria does not improve with rest alone.

If not treated promptly, malaria can develop into severe malaria, which can affect vital organs. Symptoms of severe malaria include confusion, difficulty breathing, and seizures. Severe malaria can be life-threatening, particularly for vulnerable groups such as children, pregnant women, and the elderly. Recognising the symptoms early and seeking prompt treatment is crucial to avoid complications and ensure a full recovery.

What Does Malaria Treatment Involve?

When malaria is diagnosed, doctors typically treat it with antimalarial medicines. The most commonly prescribed first line of treatment is Chloroquine and second line is ACT (Artesunate and Sulfadoxine-Pyrimethamine) combination, which combines two medications that work together to kill the parasite.

Doctors consider several factors when deciding on the best treatment, including which Plasmodium parasite is present, the patient's symptoms, age, health, weight, and whether they have had malaria before or taken similar medicines.

However, treating malaria can sometimes be tricky. Some Plasmodium parasites have developed resistance to older medications, making treatment less effective.


Why is Early Diagnosis Such a Big Deal ?

Early diagnosis plays a crucial role in managing malaria and preventing its progression to severe stages. Here’s why it’s so important:

  • Catch the infection before it gets serious: The earlier you know, the faster you can stop the infection from spreading and causing organ damage, avoiding the need for ICU care, oxygen, or expensive procedures.
  • Medicine works better when started early: In the early stages, the parasite count in your blood is low, making it easier for medicines to clear it out. You’re also less likely to build drug resistance or require stronger doses.
  • It saves time, money, and lives: Early treatment typically means you won’t need hospital admission, saving money. It also helps reduce the spread of malaria in your area, protecting others in your home or neighbourhood from falling ill.


How is Malaria Diagnosed ?

If someone experiences a recurring fever with chills, it’s important to get tested rather than guessing the cause. Malaria is typically diagnosed using two key tests in clinics and labs:

  • RDT (Rapid Diagnostic Test): This test provides results within 15 to 20 minutes, offering a quick way to confirm malaria.
  • Microscope Test: A blood sample is examined under a microscope to detect the presence of malaria parasites in the blood.

Both of these tests are simple and require only a small drop of blood.


What Happens After You're Diagnosed ?

Once diagnosed with malaria, treatment usually begins immediately. In non-severe cases, you may not need to stay in the hospital, and the doctor will start the malaria treatment on the same day. The treatment plan typically includes:

  • The right medicine based on your test results: Doctors will prescribe antimalarial medications suited to the type and severity of malaria.
  • Advice on diet, water, and follow-up care: Staying hydrated and maintaining a proper diet is essential for recovery.

If you're feeling weak, doctors may ask for a few basic blood tests to track your progress during treatment.


What to Do During Recovery

Even if you start feeling better after a couple of days, it’s crucial to complete the full course of medication to avoid a relapse. Here are some recovery tips:

  • Drink fluids: Water, ORS (Oral Rehydration Solution), coconut water, or lemon water help to stay hydrated.
  • Eat light food: Options like khichdi, fruits, soft vegetable curry, and roti with dal are easy on the stomach.

For non-vegetarian meals, you can consume boiled eggs, fish curry with rice, or soft chicken soup, as long as your stomach tolerates it.

  • Rest properly: Even if you feel okay, it’s essential to rest to support the body’s full recovery.


How Can You Prevent Malaria?

Preventing malaria is all about keeping mosquitoes away and reducing the risk of being bitten. Here are some effective ways to protect yourself and your family:

  • Use Mosquito Nets: Always sleep under a mosquito net, especially if your windows remain open. This helps protect you from mosquito bites during the night when mosquitoes are most active.
  • Apply Repellents: Use mosquito repellents on your hands and feet, particularly in the evening, when mosquitoes are most likely to bite.
  • Maintain Clean Water Storage: Ensure that water storage areas like pots, coolers, and tanks are cleaned regularly. Don’t let water collect in any stagnant places, as these are breeding grounds for mosquitoes.
  • Regularly Spray Rooms: Use insecticide sprays in rooms to kill any mosquitoes that may be inside. Most people only think about spraying after someone falls ill, but it’s much better to prevent the problem before it arises.


Preventive Medicine for Travellers

If you’re planning to travel to malaria-prone areas such as forests or rural zones, it’s important to consult your doctor beforehand. Some people, particularly those with weaker immunity or pregnant women, may be prescribed preventive malaria medicines to avoid getting infected.


Conclusion

Malaria isn’t hard to treat, but only if you catch it early. That one test can save you from days of illness, expensive treatment, and even hospitalisation. Malaria treatment is more effective when the parasite hasn’t spread too much.
