Clinical Features of Malaria
Clinical presentation. Infection with malaria parasites may result in a wide variety of symptoms, ranging from absent or very mild symptoms to severe disease and even death. Malaria disease can be categorized as uncomplicated or severe (complicated). In general, malaria is a curable disease if diagnosed and treated promptly and correctly.

Clinical review: Severe malaria
Cerebral malaria is the most common clinical presentation and cause of death in adults with severe malaria. The onset may be dramatic with a generalized convulsion, or gradual with initial drowsiness and confusion, followed by coma lasting from several hours to several days.
Importantly, virtually all patients with malaria present with headache. Clinical symptoms include the following: Cough. Fatigue. Malaise. Shaking chills. Arthralgia. Myalgia. Patients experience a paroxysm of fever, shaking chills, and sweats (every 48 or 72 h, depending on species).
Treatment of Severe Malaria
Criteria for severe malaria. Patients with any manifestations of severe malaria, e.g., impaired consciousness/coma, hemoglobin <7 g/dL, acute kidney injury, acute respiratory distress syndrome, circulatory collapse/shock, acidosis, jaundice (with other signs of severe malaria), disseminated intravascular coagulation, and/or parasite density of ≥5% should be treated promptly and aggressively ...
Severe malaria
Severe malaria is a medical emergency. It is a major cause of preventable childhood death in tropical countries. Severe malaria justifies considerable global investment in malaria control and elimination yet, increasingly, international agencies, funders and policy makers are unfamiliar with it, and so it is overlooked. In sub-Saharan Africa, severe malaria is overdiagnosed in clinical practice.

Malaria
Malaria is a parasitic infection transmitted by the Anopheles mosquito that leads to acute life-threatening disease and poses a significant global health threat. Two billion people risk contracting malaria annually, including those in 90 endemic countries and 125 million travelers, and 1.5 to 2.7 million people die in a year.[1] The Plasmodium parasite has a multistage lifecycle, which leads ...
PDF Review of Malaria Diagnosis and Treatment in the United States
Clinical characteristics of locally acquired mosquito-transmitted malaria — U.S., May-July 2023. All 8 individuals were adults and had fever. 7/8 (88%) individuals were hospitalized. All 8 individuals received oral antimalarial treatment. All received treatment to prevent future disease relapse.

Clinical presentation Malaria is separated conveniently into two disease presentations: uncomplicated and severe. Symptoms of uncomplicated malaria are very non-specific, and can include fever, chills, body-aches, headache, cough, and diarrhoea, making clinical diagnosis unreliable.

Severe Malaria Signs and Symptoms
Using data compiled from prospective series of severe P. falciparum malaria studies, a TMIH supplement on severe malaria shows the prevalence of different features of severe P. falciparum malaria by age on the left side, and the mortality in children and adults associated with manifestations of cerebral and renal impairment and metabolic acidosis alone or in combination using Venn diagrams on ...
The complexities of malaria disease manifestations with a focus on
Malaria is a serious parasitic disease in the developing world, causing high morbidity and mortality. The pathogenesis of malaria is complex, and the clinical presentation of disease ranges from severe and complicated, to mild and uncomplicated, to asymptomatic malaria. Despite a wealth of studies on the clinical severity of disease, asymptomatic malaria infections are still poorly understood.
Clinical features
Presentation may be delayed in people who have taken chemoprophylaxis. Most missed cases of malaria are wrongly diagnosed as non-specific viral infections, influenza, gastroenteritis, and hepatitis. Clinical features of malaria include: Fever (often 39°C or higher), sweats, ... Features of severe or complicated malaria in adults include:
Clinical Aspects of Uncomplicated and Severe Malaria
The clinical manifestations of malaria are dependent on the previous immune status of the host. 7 In areas where endemicity of P. falciparum malaria is stable, severe malaria most commonly occurs in children up to 5 years of age, while is less common in older children and adults because of the acquisition of partial immunity. In areas of lower ...
Clinical manifestations and outcomes of severe malaria in adult
Background Malaria is a major public health concern in The Gambia. There is limited data on the clinical manifestation and outcome of severe malaria in adult patients in The Gambia. The study therefore assessed the clinical manifestations and outcome of severe malaria in adult patients admitted at the Edward Francis Small Teaching Hospital. Methods The study retrospectively reviewed the ...
Diagnosis, clinical presentation, and in-hospital mortality of severe
Background: Severe falciparum malaria with human immunodeficiency virus (HIV) coinfection is common in settings with a high prevalence of both diseases, but there is little information on whether HIV affects the clinical presentation and outcome of severe malaria. Methods: HIV status was assessed prospectively in hospitalized parasitemic adults and children with severe malaria in Beira ...

Cerebral malaria is a clinical syndrome of impaired consciousness associated with malaria in the absence of hypoglycemia, convulsions, drugs, and nonmalarial causes characterized by unrousable coma defined by a Glasgow Coma Score less than11 (adults) or Blantyre Coma Score less than 3 (children) .Two large intervention trials in Asian adults and African children with severe malaria found that ...

The clinical presentation and outcome of severe vivax malaria was found to be similar to severe malaria caused by P. falciparum and mixed infection, except for higher chances of severe anaemia among the children infected with P. falciparum (P = 0·04).

Clinical immunity to malaria involves epigenetic reprogramming of
The regulation of inflammation is a critical aspect of disease tolerance and naturally acquired clinical immunity to malaria. Here, we demonstrate using RNA sequencing and epigenetic landscape profiling by cytometry by time-of-flight, that the regulation of inflammatory pathways during asymptomatic parasitemia occurs downstream of pathogen sensing-at the epigenetic level.
Pharmacokinetic Models of Tafenoquine: Insights for Optimal Malaria
Malaria is a preventable and treatable infectious disease that spreads worldwide and is caused by protozoan parasites of the genus Plasmodium, which are transmitted through the bites of infected female Anopheles mosquitoes [].The most common and prevalent species infecting humans are P. falciparum and P. vivax, and clinical disease manifestation depends on the level of immunity [].
ABO and Rhesus blood group variability and their associations with
Background Plasmodium falciparum infection is associated with the human ABO blood group. However, there is a paucity of data on the role that ABO and Rhesus blood groups play in malaria clinical presentations. Therefore, the objective of this study was to assess the association of human ABO blood groups and the Rhesus blood (Rh) types with the severity of malaria. Methods This cross-sectional ...
Clinical and Lab profile of severe and uncomplicated malaria: A
Clinical presentation of malaria varies from asymptomatic infection to benign/uncomplicated disease and even severe/fatal cases depending on host and environmental factors.5 While P.vivax was considered to cause uncomplicated malaria previously, systematic review of clinical studies of severe malaria has shown increase in severe and even fatal ...
Cellular immune response to SARS-CoV-2 and clinical presentation in
Tapela et al. study the impact of previous malaria exposure on people with COVID-19. Prior malaria exposure may influence the immune response to SARS-CoV-2 and might be linked to milder COVID-19 cases in malaria-endemic regions, offering valuable insights for viral disease management and outbreak control in these populations.
