Article Abstract
Introduction: Infection with is a recognized cause of severe malaria including deaths. The exact burden and patterns of severe monoinfections is however still not well quantified, especially in endemic regions. We examined the magnitude and patterns of severe malaria caused by monoinfections of and associated predictors among patients admitted to a tertiary care center for malaria in Vietnam.
Methods: A retrospective cohort study was conducted based on the patients' medical records at the Hospital for Tropical Diseases from January 2015 to December 2018. Extracted information included demographic, epidemiologic, clinical, laboratory and treatment characteristics.
Results: Monoinfections with were found in 153 (34.5, 95% CI 30.3-39.1%) patients of whom, uncomplicated and severe malaria were documented in 89.5% (137/153, 95% CI 83.7-93.5%) and 10.5% (16/153, 95% CI 6.5-16.3%), respectively. Patterns of severe malaria included jaundice (8 cases), hypoglycemia (3 cases), shock (2 cases), anemia (2 cases), and cerebral malaria (1 case). Among 153 patients, 73 (47.7%) had classic malaria paroxysm, 57 (37.3%) had >7 days of illness at the time of admission, and 40 (26.1%) were referred from other hospitals. A misdiagnosis as having other diseases from malaria cases coming from other hospitals was up to 32.5% (13/40). Being admitted to hospital after day 7th of illness (AOR = 6.33, 95% CI 1.14-35.30, p = 0.035) was a predictor of severe malaria. Severe malaria was statistically associated with longer hospital length of stay (p = 0.035). Early and late treatment failures and recrudescence were not recorded. All patients recovered completely.
Discussion: This study confirms the emergence of severe vivax malaria in Vietnam which is associated with delayed hospital admission and increased hospital length of stay. Clinical manifestations of infection can be misdiagnosed which results in delayed treatment. To meet the goal of malaria elimination by 2030, it is crucial that the non-tertiary hospitals have the capacity to quickly and correctly diagnose malaria and then provide treatment for malaria including infections. More robust studies need to be conducted to fully elucidate the magnitude of severe in Vietnam.

Although China has achieved malaria elimination certification, the risk of malaria transmission reintroduction due to imported malaria remains. We analyzed data on imported malaria cases collected from January 1, 2014 to December 31, 2021, using multivariable logistic regression analysis to identify the factors associated with severe and relapsing malaria. The odds of severe malaria were around 4-fold greater for patients who were initially diagnosed with a nonmalarial illness than for patients initially diagnosed with malaria.

Unexplained fever poses significant diagnostic challenges in resource-limited settings like Bamako, Mali, where overlapping endemic diseases include malaria, HIV/AIDS, yellow fever, typhoid, and others. This study aimed to elucidate the infectious etiologies of acute febrile illnesses in this context. Acute febrile patients of any age were enrolled after informed consent or assent.

Malaria remains a significant global health challenge, particularly in endemic regions of Africa, with being the most virulent species. This case report details the presentation of a 24-year-old Caucasian woman who collapsed at a train station in the United Kingdom after experiencing a week of fever, malaise, abdominal pain, and gastrointestinal symptoms. At emergency care, she was initially resuscitated with intravenous fluids and antipyretics.

Malaria kills millions of people annually, and it is one of the major causes of preventable mortality in the world. Of the different plasmodium species that induce malaria, Plasmodium falciparum and Plasmodium vivax account for the most severe form of malarial disease in humans. This review focuses on understanding preventive measures, mutation-based disease evolution, malaria-related biomarkers, and potential plant bioactive components for the treatment and management of malaria.

Streptococcus pneumoniae and influenza A virus (IAV) are significant agents of pneumonia cases and severe respiratory infections globally. Secondary bacterial infections, particularly by Streptococcus pneumoniae, are common in IAV-infected individuals, leading to critical outcomes. Despite reducing mortality, pneumococcal vaccines have high production costs and are serotype specific.
