Quick answer: Malaria develops in two main stages inside the body — a liver stage and a blood stage — and the blood stage produces cyclical fever with chills, sweating, headache and body ache. Malaria does not usually cause a skin rash; visible signs are more often paleness (pallor) or yellowing (jaundice). Any high fever with chills needs a malaria blood test.
Key takeaways
- Malaria has a liver stage (no symptoms) and a blood stage (when you feel unwell).
- The classic sign is a fever cycle — chills and shivering, then high fever, then sweating.
- Malaria usually does not cause a rash — that is more typical of dengue or viral fever.
- On the skin, malaria more often shows as pallor (paleness) or jaundice (yellowing).
- A blood test (rapid test or smear) is needed to confirm malaria.
- Confusion, breathlessness, jaundice or very high fever can mean severe malaria — an emergency.
What are the stages of malaria?
Malaria is caused by the Plasmodium parasite, spread by the bite of an infected Anopheles mosquito. After a mosquito bite, the parasite goes through stages inside the body before symptoms appear. Understanding these stages explains why malaria causes its typical fever pattern — and why a blood test is needed to confirm it.
The malaria life cycle and stages
| Stage | Where it happens | What it means for you |
|---|---|---|
| Liver stage | In the liver, after the mosquito bite | A 'silent' stage with no symptoms; the parasite multiplies before entering the blood. |
| Blood stage | Inside red blood cells | The symptomatic stage — this is when the fever, chills and other symptoms appear. |
| Transmission stage | Back to a mosquito | Forms that can infect another mosquito, allowing malaria to spread. |
The time between the mosquito bite and the first symptoms (the incubation period) is often 10–15 days, but can be longer depending on the type of malaria parasite.
Malaria symptoms by stage (the fever cycle)
When the blood stage begins, malaria often causes a repeating fever cycle (called a paroxysm) with three parts:
- Cold stage: shivering, chills and feeling very cold.
- Hot stage: high fever, headache, body ache, nausea and weakness.
- Sweating stage: heavy sweating as the fever falls, followed by tiredness.
This cycle can repeat every day or two, depending on the malaria type. Other common symptoms include headache, body and muscle aches, tiredness, poor appetite, nausea and sometimes vomiting.
What does malaria look like on the skin?
Many people search for what malaria 'looks like' on the skin. It is important to know:
Myth vs fact: does malaria cause a rash?
- Myth: malaria causes a typical skin rash.
- Fact: malaria does not usually cause a rash. A prominent rash points more towards dengue, chikungunya or a viral fever.
- On the skin, malaria can show as pallor (paleness) from anaemia, or jaundice (yellowing of the eyes and skin) — but these are seen only in very severe cases, which are not very common.
- Because these fevers can look similar and a rash can be confusing, a blood test is the only reliable way to know which infection it is.
Malaria vs dengue vs viral fever
This general comparison helps tell common monsoon fevers apart, but only a blood test can confirm the cause.
| Feature | Malaria | Dengue | Viral fever |
|---|---|---|---|
| Fever pattern | Cyclical fever with chills and sweating | Sudden high fever with severe body pain | Fever with cold-like symptoms |
| Skin signs | Usually none (no typical rash) | Rash can occur; easy bruising/bleeding in warning cases | Mild or no rash |
| Other clues | Shivering, sweating cycles, anaemia | Pain behind the eyes, low platelets | Runny nose, sore throat, cough |
| Confirmed by | Malaria rapid test (RDT) or blood smear | NS1 / IgM blood test, CBC | Usually clinical; tests to rule out others |
How malaria is diagnosed — and when to test
Malaria is confirmed with a blood test — either a rapid diagnostic test (RDT) or a blood smear examined under a microscope. You should see a doctor and get tested for any high fever with chills, especially during or after the rainy season, or after travel to a malaria-prone area. Testing early helps start the right treatment sooner.
Severe malaria — warning signs
Warning signs — seek emergency care if there is:
- Confusion, drowsiness, or a seizure
- Difficulty breathing or fast breathing
- Yellowing of the eyes or skin (jaundice)
- Bleeding, or very dark/reduced urine
- Very high fever that will not settle
- Extreme weakness, inability to sit or stand, or repeated vomiting
These can be signs of severe malaria, which is a medical emergency — especially in children, elderly people and pregnant women. Seek in-person emergency care immediately.
Special care: children, elderly people and pregnancy
- Children: can become seriously ill quickly — seek testing and care early for fever with chills.
- Elderly people: may show weakness or confusion; other illnesses can complicate malaria.
- Pregnancy: malaria in pregnancy is higher-risk and needs prompt medical care; never take anti-malarial or other medicines on your own — consult your doctor.
Can malaria be assessed through an online consultation?
Suitable for teleconsultation: For fever with chills, an online consultation with a General Physician is a good first step — the doctor can review your symptoms, advise on the right blood test, guide hydration and home care, and interpret your reports.
Limitations: Malaria needs a confirmed diagnosis and proper treatment, and severe malaria is an emergency. If any warning sign above appears, seek in-person emergency care immediately.
Talk to a doctor online
If you have fever with chills, you can consult a General Physician online on DocGenie to review your symptoms, decide on testing, and get safe guidance — and clear advice on when in-person care is needed.

Frequently asked questions
What are the stages of malaria?
Malaria has a silent liver stage (no symptoms) and a symptomatic blood stage, when fever and other symptoms appear. The blood stage causes the classic fever cycle of chills, high fever and sweating.
What does malaria look like on the skin?
Malaria does not usually cause a rash. On the skin it more often shows as pallor (paleness) from anaemia, or jaundice (yellowing of the eyes and skin) in more severe cases. A prominent rash suggests dengue or a viral fever instead.
Does malaria cause a rash?
Not typically. A noticeable rash points more towards dengue, chikungunya or viral fever. Because these can look similar, a blood test is the reliable way to confirm malaria.
What are the first symptoms of malaria?
Early malaria often begins with fever, chills and shivering, headache, body aches, tiredness and sometimes nausea, typically about 10–15 days after an infected mosquito bite.
How is malaria diagnosed?
With a blood test — a rapid diagnostic test (RDT) or a blood smear under a microscope. See a doctor for any high fever with chills, especially in the rainy season.
When is malaria an emergency?
Seek emergency care for confusion, drowsiness or seizures, difficulty breathing, jaundice, bleeding, very dark or reduced urine, or very high fever — these can indicate severe malaria.
