C1348992

 A

In the UK NHS setting, the indication for a malaria screen in an 11-year-old child who has had mosquito bites, recent travel to Ethiopia, and did not receive malaria prophylaxis would be:

Yes – Screen for Malaria

Reasons:

  1. Travel to a malaria-endemic area (Ethiopia) – high-risk region for Plasmodium falciparum.

  2. No prophylaxis taken – increases risk of infection.

  3. Mosquito bites reported – possible exposure to the malaria parasite.

  4. Child's age (11 years) – children are at increased risk for complications from malaria.

  5. NHS guidelines (e.g. UKHSA / NICE / RCPCH) recommend screening any febrile illness or suggestive symptoms after travel to an endemic area, especially without prophylaxis.

Even without symptoms:

  • Malaria can present atypically in children, or early symptoms may be mild.

  • Consider testing if fever, malaise, headache, GI upset, or myalgia is present — or any unexplained illness in returning travelers.

Would you like a quick summary of what the NHS malaria screen usually includes?

In the UK NHS, when malaria is suspected, the recommendation is to perform a series of 3 malaria screens (blood films):

Why 3 malaria screens are needed:

  1. Parasite detection can vary – Malaria parasites may not be visible in a single blood sample due to their lifecycle and intermittent presence in peripheral blood.

  2. Increases diagnostic sensitivity – Repeated tests improve chances of catching low-level or fluctuating parasitemia.

  3. Guideline standard – NHS and UKHSA guidance recommends three thick and thin blood films taken 12–24 hours apart over a 48-hour period.


🔍 Summary of the NHS protocol:

  • Initial screen: Thick and thin film + rapid diagnostic test (RDT) if available.

  • If negative but malaria is still suspected: Repeat 2 more films at intervals (usually every 12–24 hours).

  • All samples must be examined by experienced microscopists.
