Alphaviruses are mosquito-transmitted RNA viruses which generally cause acute disease including mild febrile illness, rash, arthralgia, myalgia and more severely, encephalitis. In the mouse, peripheral infection with Semliki Forest virus (SFV) results in encephalitis. With non-virulent strains, infectious virus is detectable in the brain, by standard infectivity assays, for around ten days. As we have shown previously, in severe combined immunodeficient (SCID) mice, infectious virus is detectable for months in the brain...

REVIEW
José Moreira, Clarisse S Bressan, Patricia Brasil, Andre M Siqueira
BACKGROUND: The causes of acute febrile illness (AFI) in Latin America (LA) are diverse and its complexity increase as the proportion of fever due to malaria decreases as control and new pathogens emerge in the region. In this context, it is important to shed light over the gaps on the epidemiological characteristics and the geographic range for many AFI aetiologies. AIMS: To review studies on community-acquired fever etiology other than malaria in LA, and to highlight knowledge gaps and challenges needing further investigation...

Since 2005, Chikungunya virus (CHIKV) re-emerged and caused numerous outbreaks in the world, and finally, was introduced into the Americas in 2013. The lack of CHIKV-specific therapies has led to the use of non-specific drugs. Chloroquine, which is commonly used to treat febrile illnesses in the tropics, has been shown to inhibit CHIKV replication in vitro. To assess the in vivo effect of chloroquine, two complementary studies were performed: (i) a prophylactic study in a non-human primate model (NHP); and (ii) a curative study "CuraChik", which was performed during the Reunion Island outbreak in 2006 in a human cohort...

OBJECTIVE: Febrile proteinuria is functional proteinuria and is seen as a transitory phenomenon during acute febrile illness, mainly viral infections. It is a benign phenomenon and clears promptly with resolution of the infection. CLINICAL PRESENTATION AND INTERVENTION: In this report, we present a patient who was thought to have febrile proteinuria. Persistence of significant proteinuria after resolution of the infection prompted biochemical and genetic work-up which lead to the diagnosis of Dent-2 disease...

Hemophagocytic lymfohistiocytosis (HLH) is rare, life-threatening condition, characterized by excessive activation of immune system with subsequent proinflammatory state resulting in multiorgan failure. Most frequently, it appears in infancy as a primary disorder caused by mutation of immune-regulatory genes. Increasingly, HLH is being diagnosed as a secondary - adult - form, which occurs as a result of aberrant immune response. Viral or bacterial systemic infections, malignancy with a predominance of lymphoproliferative disorders and autoimmune diseases are the most common triggers...

Chikungunya fever is an arthropod-borne infection caused by Chikungunya virus (CHIKV). Even though clinical features of Chikungunya fever in the Mexican population have been described before, there is no detailed information. The aim of this study was to perform a full description of the clinical features in confirmed Chikungunya-infected patients and describe the molecular epidemiology of CHIKV. We evaluated febrile patients who sought medical assistance in Tapachula, Chiapas, Mexico, from June through July 2015...

BACKGROUND: New-onset refractory status epilepticus (NORSE) refers to a clinical presentation in a patient without active epilepsy or other existing relevant neurological disorder, with new onset of refractory status epilepticus in the absence of a clear acute or active structural, metabolic, or toxic cause. Febrile infection-related epilepsy syndrome (FIRES) is a subset of NORSE that requires a febrile infection between 24 hours and 2 weeks prior to the onset of refractory status epilepticus, with or without fever at the onset of status epilepticus, and with no restriction to the age of the patient...

The intracellular pathogen Rickettsia felis causes flea-borne spotted fever and is increasingly recognized as an emerging cause of febrile illness in Africa, where co-infection with Plasmodium falciparum is common. Rickettsiae invade endothelial cells. Little is known, however, about the early immune responses to infection. In this study, we characterize for the first time the cytokine profile in the acute phase of illness caused by R. felis infection, as well as in plasmodial co-infection, using serum from 23 febrile children < 15 years of age and 20 age-matched healthy controls from Ghana...

BACKGROUND Influenza viruses induce uncomplicated infections in most cases in individuals with no known predisposing factors. Acute febrile illness is generally limited to upper respiratory symptoms and several constitutional symptoms, including headache, lethargy, and myalgia. However, influenza A virus is a cause of severe morbidity and mortality worldwide. Some patients are at risk for serious and fatal complications. Cardiac involvement is a well-known condition, but, clinically apparent influenza myocarditis is not common...

Background: Differentiating scrub typhus from other acute febrile illness is difficult due to non specificity of clinical symptoms and relative absence of eschar in Indian population. The diagnosis thus relies mainly on laboratory tests. Antibody based serological tests are mainstay of scrub typhus diagnosis. Here, we evaluated the diagnostic performance of IgM ELISA, IgM IFA and ICT to detect antibodies against O. tsutsugamushi in acute serum of febrile patients. Methodology: The serum samples from 600 randomly selected patients suffering from acute undifferentiated fever were tested by all the three tests mentioned above...

BACKGROUND: Carnitine palmitoyltransferase II deficiency (CPT II) is an autosomal recessive disorder and the most common inherited disorder of mitochondrial long-chain fatty acid oxidation, characterised by attacks of myalgia and myoglobinuria. The most common "classic" myopathic form occurs in young adults and is characterised by recurrent episodes of rhabdomyolysis triggered by prolonged exercise, fasting or febrile illness. CASE PRESENTATION: We present a case of a 22-year-old Caucasian male admitted to our hospital with fever, dyspnea, fatigue, myalgia and dark urine (brown-coloured)...

There is no definitive predictor of dengue severity, and this has led to a very large number of unnecessary hospitalizations worldwide. Although mast cell mediators are believed to a play role in dengue severity, the lack of precise kinetic data demands further research on early predictors. We enrolled 111 patients with confirmed dengue and 85 with "other febrile illness" (OFI) in a hospital-based prospective study in Vietnam. Dengue patients were classified as level 1, 2, or 3 based on the clinical intervention received...

We report identification of Madariaga virus (MADV) in plasma and urine samples from a child with acute undifferentiated febrile illness in Venezuela. Our data document the occurrence of milder MADV infections (ie, without encephalitis), with a symptom complex that resembles that seen with other arboviral infections, including dengue and zika.

Scrub typhus (ST) is an underdiagnosed acute febrile illness in the Asia Pacific region with recent reemergence. Clinical diagnosis is difficult, and laboratory confirmation is largely based on serological and molecular tests. However, Weil-Felix test still remains the only test available in much of the rural tropics where a disproportionate number of cases occur. Sensitive and affordable assays are important for broader use and accurate diagnosis. We evaluated the diagnostic capabilities of serological and molecular assays on single acute clinical samples...

Scrub typhus is becoming a clinically important cause of acute undifferentiated febrile illness in Taiwan. The incubation period is between 6 and 21 days after exposure. It is transmitted by chiggers (larva of trombiculid mite) in long grasses and in dirt-floor homes, with infection characterized by a flu-like illness of fever, headache, and myalgia lasting approximately 1 week. It has various systemic manifestations, including GI symptoms. In some, the illness progresses to multiorgan dysfunction syndrome and death...

Children with citrullinaemia commonly present in the neonatal period with life-threatening hyperammonaemia and progressive encephalopathy. Less often, 'hypomorphic' or mild late-onset childhood or adult-onset forms may be seen with intermittent neurological symptoms or acute crisis in pregnancy. We describe an 11-year-old boy with late-onset citrullinaemia manifesting as brief episodes of ataxia triggered by minor febrile illnesses, significant citrullinaemia, mild hyperammonaemia, normal neurological examination and mild cerebellar atrophy...

Scrub typhus is a mite borne infectious disease which has re-emerged in India in the 3rd millennium after years of quiescence. In this review, the authors hypothesize the various factors responsible for resurgence of this disease. The main drivers that could have contributed to the upsurge in scrub typhus cases in past two decades are changes in land use land cover (LULC) and urbanisation which are; as a result of the population explosion, causing a strain on sanitation and also increased diversion of forest land for agricultural use...

Chikungunya is an arbovirus that is transmitted by the Aedes mosquito causing a febrile illness with periodic outbreaks in large parts of the world. In the last decade it has become a public health concern in a host of countries and has affected international tourists. In the vast majority of cases Chikungunya presents as an acute febrile illness, associated with rash, headache, myalgia and debilitating arthralgia or even polyarthritis. A small proportion of patients present atypically with nervous, ocular, renal, myocardial, respiratory and renal system involvement and may require ICU management...

Group A beta-hemolytic streptococcus can cause several postinfectious, nonsuppurative immune- mediated diseases including acute rheumatic fever, poststreptococcal reactive arthritis, pediatric autoimmune neuropsychiatric disorders, and poststreptococcal glomerulonephritis. Except for sporadic outbreaks, poststreptococcal autoimmune syndromes occur most commonly in sub-Saharan Africa, India, Australia, and New Zealand. Children younger than three years are rarely affected by group A streptococcus pharyngitis or rheumatic fever, and usually do not require testing...
