Dengue, malaria, and typhoid are three of the most common infectious diseases in tropical and subtropical countries like India. Despite being caused by different pathogens—viruses, parasites, and bacteria respectively—they often present with similar symptoms such as fever, fatigue, and body aches, making accurate diagnosis essential.
At Sparsh Diagnostic Centre, we help patients identify and differentiate between these infections through a combination of clinical evaluation and advanced diagnostic tests. In this blog, we explore the key differences between dengue, malaria, and typhoid in terms of causes, transmission, symptoms, diagnosis, treatment, and prevention.
What Are These Diseases?
Dengue
Caused by: Dengue virus (a Flavivirus)
Transmitted by: Aedes aegypti mosquito
Incubation period: 4–10 days
Affected organs: Blood vessels, liver, bone marrow
Malaria
Caused by: Plasmodium parasites (mainly P. falciparum and P. vivax)
Transmitted by: Female Anopheles mosquito
Incubation period: 7–30 days
Affected organs: Liver, red blood cells, spleen
Typhoid
Caused by: Salmonella typhi bacteria
Transmitted by: Contaminated food or water (fecal-oral route)
Incubation period: 6–30 days
Affected organs: Intestines, liver, spleen
Key Differences in Symptoms
| Symptom | Dengue | Malaria | Typhoid |
|---|---|---|---|
| Fever Pattern | Sudden high-grade (up to 104°F) | Cyclical fever with chills & sweats | Gradual onset, step-ladder pattern |
| Headache | Intense, persistent | Moderate to severe | Mild to moderate |
| Muscle & Joint Pain | Severe (“breakbone fever”) | Present but milder | Mild or absent |
| Nausea & Vomiting | Common | Common | Very common |
| Diarrhea/Constipation | Rare | Rare | Common (early constipation, later diarrhea) |
| Abdominal Pain | Mild | Mild to moderate | Persistent and common |
| Skin Rash | Appears 2–5 days after fever onset | Rare | Sometimes present (“rose spots”) |
| Chills & Sweating | Rare | Classic symptom | Rare |
| Enlarged Spleen/Liver | In severe cases | Common | Common |
| Bleeding (Gums/Nose) | Severe dengue | Rare | Rare |
| Mental Confusion/Delirium | Rare | In cerebral malaria | Severe cases |
| Onset of Symptoms | Sudden | Gradual or sudden | Gradual |
Differences in Diagnosis
Dengue
Blood Tests:
NS1 antigen (early detection)
IgM and IgG antibodies
Platelet count (often low)
Hematocrit (often high)
Clinical signs: Rash, severe headache, pain behind the eyes
Malaria
Blood Smear Microscopy:
Thick and thin blood smear to identify Plasmodium species
Rapid Diagnostic Tests (RDTs):
Detect malaria antigens
Other Tests:
Hemoglobin level, liver enzymes
Typhoid
Widal Test:
Detects antibodies against Salmonella antigens
Typhidot/IgM Tests
Blood Culture:
Most reliable in early stages
May show low WBCs and platelets
At Sparsh Diagnostic Centre, we offer all the above tests with same-day reporting for faster treatment decisions.
Treatment Differences
Dengue
No antiviral treatment
Supportive care:
Hydration (oral or IV)
Paracetamol for fever
Monitoring for bleeding or shock
Avoid NSAIDs (like ibuprofen or aspirin, due to bleeding risk)
Severe dengue may need ICU care, transfusion
Malaria
Antimalarial medications:
Chloroquine, Artesunate, Quinine, Mefloquine (based on resistance patterns)
Hospitalization in severe cases (especially P. falciparum)
IV fluids, antipyretics, and blood transfusions if anemia occurs
Typhoid
Azithromycin, Ciprofloxacin, or Ceftriaxone (based on resistance)
Supportive care:
Fluids and nutrition
Antipyretics
Severe cases may require hospitalization and IV antibiotics
Risk Factors and Complications
Dengue
Risk Factors:
Urban areas with stagnant water
Complications:
Malaria
Risk Factors:
Travel to or residence in endemic areas
Poor mosquito protection
Complications:
Cerebral malaria
Typhoid
Risk Factors:
Poor sanitation or hygiene
Contaminated water/food
Complications:
Intestinal perforation
Internal bleeding
Sepsis
Prevention Tips
General Preventive Measures
Use insect repellents
Wear full-sleeved clothing
Sleep under mosquito nets
Avoid stagnant water around the house
Dengue and Malaria
Mosquito control is key
Keep your environment clean
Use insecticide-treated nets and sprays
No vaccines for dengue widely available in India yet
Malaria prophylaxis pills for travelers to high-risk areas
Typhoid
Drink clean water
Avoid raw street food
Practice hand hygiene
Vaccination available (Typhoid Conjugate Vaccine)
How to Know Which Disease You Might Have?
All three illnesses may begin with fever, headache, and body pain, but certain features help you tell them apart:
| Feature | Likely Disease |
|---|---|
| Sudden high fever + rash + severe body pain | Dengue |
| Cyclical chills/sweats + travel to endemic zone | Malaria |
| Gradual fever + persistent abdominal pain + constipation | Typhoid |
Still unsure? It’s always safest to get tested. At Sparsh Diagnostic Centre, we offer reliable testing for all three under one roof.
Why Early Diagnosis Matters
Delayed treatment can lead to:
Dengue turning into hemorrhagic shock
Malaria progressing to cerebral involvement
Typhoid causing intestinal rupture
With the right diagnosis, these complications can be avoided. Act early. Get tested. Stay safe.
