Malaria - Symptoms, Causes & Treatment
Malaria is a life-threatening mosquito-borne disease caused by Plasmodium parasites, transmitted through the bite of infected Anopheles mosquitoes.
Overview
India accounts for about 2% of global malaria cases. While the incidence has been decreasing, malaria remains a significant public health concern, particularly in rural and tribal areas.
Malaria can be fatal if not treated promptly. Early diagnosis through rapid diagnostic tests and proper antimalarial treatment can prevent complications and death.
Symptoms of Malaria
- FeverPrimary
Fever is a temporary increase in body temperature, usually above 100.4°F (38°C). It is a sign that the body is fighting an infection or illness.
- HeadachePrimary
A headache is pain or discomfort in the head, scalp, or neck. Most headaches are not serious and can be treated with lifestyle changes and medication.
- Muscle Pain
Muscle pain (myalgia) is aching or soreness in muscles that can range from mild to severe. It can affect a small area or the entire body.
- Nausea
Nausea is an uneasy feeling in the stomach that often comes before vomiting. It can be caused by many conditions including infections, pregnancy, motion sickness, and digestive disorders.
- Fatigue
Fatigue is a feeling of persistent tiredness or exhaustion that does not improve with rest. It can be physical, mental, or both, and may indicate an underlying health condition.
- Diarrhea
Diarrhea is characterized by loose, watery stools occurring more frequently than usual. It can be acute (lasting 1-2 days) or chronic (lasting more than 4 weeks).
Causes of Malaria
Plasmodium parasites (P. vivax and P. falciparum most common in India)
Transmitted by female Anopheles mosquito bites (evening/night)
Can rarely be transmitted through blood transfusion
Mother-to-child transmission during pregnancy
Treatment for Malaria
Artemisinin-based combination therapy (ACT) for P. falciparum
Chloroquine for P. vivax malaria
Primaquine for preventing relapse of P. vivax
IV artesunate for severe malaria
Supportive care (fluids, antipyretics)
Blood transfusion for severe anemia
Dialysis for kidney complications
Prevention
Use insecticide-treated bed nets
Indoor residual spraying with insecticides
Apply mosquito repellent
Wear protective clothing during evening/night
Eliminate mosquito breeding sites
Antimalarial prophylaxis for travelers
Prompt diagnosis and treatment
Risk Factors
Living in or traveling to malaria-endemic areas
Rural and tribal areas
Rainy season
Pregnancy
Children under 5
Weakened immune system
Lack of preventive measures
When to See a Doctor
See a doctor immediately if you develop fever with chills and sweating (especially cyclical pattern), headache, body aches, nausea, and fatigue, particularly if you live in or have traveled to a malaria-endemic area. Seek emergency care for high fever, confusion, seizures, or dark urine.

Which Doctor to Consult for Malaria

Related Conditions
These conditions share similar symptoms with malaria and may be relevant:
Dengue
Dengue is a mosquito-borne viral infection causing high fever, severe headache, body aches, and in severe cases, potentially life-threatening bleeding and shock.
Typhoid
Typhoid fever is a bacterial infection caused by Salmonella typhi, spread through contaminated food and water, causing prolonged fever, weakness, and digestive problems.
Irritable Bowel Syndrome
Irritable Bowel Syndrome (IBS) is a common functional gastrointestinal disorder characterized by abdominal pain, bloating, and changes in bowel habits (diarrhea, constipation, or both).
Chronic Kidney Disease
Chronic kidney disease (CKD) is a gradual loss of kidney function over months or years, eventually requiring dialysis or transplant if it progresses to end-stage.
Migraine
Migraine is a neurological condition that causes recurring episodes of moderate to severe headache, often accompanied by nausea, vomiting, and sensitivity to light and sound.
Anemia
Anemia is a condition where the blood lacks enough healthy red blood cells or hemoglobin to carry adequate oxygen to the body's tissues, causing fatigue, weakness, and other symptoms.
