INTRODUCTION: Imported malaria cases continue to be reported in Sri Lanka. Similarly, hepatitis E is also considered a travel associated imported disease in Sri Lanka. This is a report of the first co-infection of malaria and hepatitis E in Sri Lanka. OBJECTIVES: A 21-year-old European who visited Sri Lanka after a 2 months stay in India, was admitted to hospital with fever, vomiting, abdominal pain, and dark-coloured urine on the 4th day after his arrival. On examination, he had splenomegaly but no hepatomegaly. He had thrombocytopaenia; 89% neutrophils; 9% lymphocytes; elevated liver enzymes and hyperbilirubinaemia. Urine was positive for bile pigment. METHODS: Considering his travel history to India, he was tested for malaria. The rapid diagnostic test became positive for Plasmodium falciparum while microscopy showed P. falciparum ring stages with a parasite density of 120/μl. He was treated as for uncomplicated P. falciparum malaria with oral Artemisinin-based Combination Therapy. The patient became fever-free and blood smears became negative after 13 hours following 2 doses of antimalarials. RESULTS: However, his liver functions were further deranged with apparent jaundice (ALT: 250 U/L; AST: 175 U/L; ALP: 130 U/L; GGT: 179 U/L; total bilirubin: 10.65 mg/dL; direct bilirubin: 8.08 mg/dL; indirect bilirubin: 2.57 mg/dL). Further blood tests detected hepatitis E-specific IgM antibodies. He was treated with oral ursodiol but no specific antiviral was given. Following the completion of antimalarials, he was discharged from the hospital upon clinical recovery. CONCLUSION: Clinicians should be vigilant on travel-associated co-infections in patients who are diagnosed with imported malaria.
The first reported case of co-infection of imported hepatitis E and Plasmodium falciparum malaria in Sri Lanka

Global travel and tourism, especially across tropical countries, may lead to importation of malaria and other infectious diseases into Sri Lanka. This case report describes the first co-infection of imported hepatitis E and Plasmodium falciparum malaria in a tourist diagnosed in Sri Lanka. The patient was initially diagnosed with uncomplicated P. falciparum malaria and was started on treatment with oral Artemisinin-based Combination Therapy (ACT). Deterioration of hepatic enzymes and hyperbilirubinaemia despite the rapid parasitological response to antimalarials led to further investigation and diagnosis of co-infecting hepatitis E in this patient. The importance of clinicians being vigilant on travel associated co-infections is highlighted to ensure early diagnosis and better patient management.
A malaria death due to an imported Plasmodium falciparum infection in Sri Lanka during the prevention of re-establishment phase of malaria
(BioMed Central, 2023) Seneviratne, S.; Fernando, D.; Chulasiri, P.; Gunasekera, K.; Thenuwara, N.; Aluthweera, C.; Wijesundara, A.; Fernandopulle, R.; Mendis, K.; Wickremasinghe, R.
BACKGROUND: Sri Lanka has maintained a rigorous programme to prevent the re-establishment of malaria ever since the disease was eliminated in October 2012. It includes efforts to sustain case surveillance to ensure early diagnosis and management of malaria. Yet, in April of 2023 the death occurred of an individual with imported malaria. CASE PRESENTATION: The deceased was a 37-year-old Sri Lankan male who returned to Sri Lanka on the 10th of April after a business trip to several countries including Tanzania. He was febrile on arrival and consulted three Allopathic Medical Practitioners in succession in his home town in the Western Province of Sri Lanka, over a period of 5 days starting from the very day that he arrived in the country. Malaria was not tested for at any of these consultations and his clinical condition deteriorated. On the evening of 14th of April he was admitted to the medical intensive care unit of a major private hospital in the capital city of Colombo with multiple organ failure. There, on a request by the treating physician blood was tested for malaria and reported early the next morning as Plasmodium falciparum malaria with a high parasitaemia (> 10%). The patient died shortly after on the 15th of April before any anti-malarial medication was administered. The deceased had been a frequent business traveller to Africa, but with no past history of malaria. He had not taken chemoprophylaxis for malaria on this or previous travels to Africa. DISCUSSION: The patient's P. falciparum infection progressed rapidly over 5 days of arriving in Sri Lanka leading to severe malaria without being diagnosed, despite him seeking healthcare from three different Medical Practitioners. Finally, a diagnosis of malaria was made on admission to an intensive care unit; the patient died before anti-malarial medicines were administered. CONCLUSIONS: This first death due to severe P. falciparum malaria reported in Sri Lanka after elimination of the disease was due to the delay in diagnosing malaria.
