Malaria

Causes & Risk Factors

Malaria is transmitted through the bite of infected Anopheles mosquitoes, with risk influenced by:

•  Living in or traveling to a malaria-endemic area.

•  Time of day and season — Anopheles mosquitoes typically bite between dusk and dawn, and transmission may vary seasonally.

•  Limited use of mosquito protection measures, including bed nets and repellents.

•  Lack of antimalarial prophylaxis when traveling to an endemic area, where recommended.

•  Previous malaria infection does not provide complete protection against future infection.

Symptoms & When to Test

Malaria symptoms classically occur in cycles, though presentation can vary depending on the infecting species.

•  Fever, often with cycles of chills, rigors, and sweating

•  Headache

•  Fatigue and body aches

•  Nausea and vomiting

•  In severe cases — confusion, difficulty breathing, or signs of organ involvement, which constitute a medical emergency

When Should You Consider Testing?

Testing is appropriate promptly for anyone with fever and a history of travel to or residence in a malaria-endemic area, since malaria can progress rapidly and requires timely diagnosis and treatment.

Why Tests Are Combined

Peripheral blood smear remains the gold-standard diagnostic method, since it can identify the malaria parasite species and estimate parasite density (parasitemia), both of which are important for guiding treatment decisions and assessing severity.

Rapid malaria antigen testing offers faster results and can be particularly useful when immediate treatment decisions are needed, though it may have some limitations compared to smear examination for species identification in certain situations.

Because different Plasmodium species can require different treatment approaches, and because malaria severity can escalate quickly, accurate species identification through smear examination (complemented by rapid antigen testing where appropriate) is an important part of correct management.

Tests Available at NPL

Most infectious-disease molecular tests and microbiological investigations do not require fasting. However, some blood tests ordered at the same time may have specific preparation requirements. Please follow the instructions provided by your doctor or NPL.

When to See a Doctor

•  Fever with a history of travel to or residence in a malaria-endemic area — seek prompt evaluation

•  Fever with cyclic chills, rigors, and sweating

•  Any signs of severe illness — confusion, difficulty breathing, severe weakness — seek urgent care immediately

•  Known malaria with worsening symptoms despite treatment
