Skin lesion in chikungunya

Acute encephalitis syndrome (AES) refers to an acute onset of fever and clinical neurological manifestation that includes mental confusion, disorientation, delirium, or coma, which may occur because of infectious or non-infectious causes. Cerebrospinal fluid (CSF) pleocytosis generally favors infectious etiology, and a normal CSF favors an encephalopathy or non-infectious AES. Among the infectious AES, viral, bacterial, rickettsial, fungal, and parasitic causes are the commonest. Geographical and seasonal clustering and other epidemiological characteristics are important in clinical decision making...

Chikungunya is a rapidly emerging infectious disease worldwide caused by a virus that belongs to the Togaviridae family. It can have varied presentations, but vesiculobullous lesions are commonly described. A widespread dissemination of such lesions, however, is extremely rare. Person-to-person transmission has not been documented, but rare reports have described maternal-fetal vertical transmission. We herein describe a unique case of congenital chikungunya resulting in a staphylococcal scalded skin syndrome-like presentation and discuss the clinical presentation, underlying pathophysiology, and how to differentiate this condition from true Stevens Johnson Syndrome-Toxic epidermal Necrolysis (SJS-TEN)...

Rickettsioses are a group of tick-borne infectious diseases. The clinical presentation is characterised by unspecified manifestations seen in illnesses such as dengue, zika, and chikungunya, so identification is complicated. The greatest impact occurs among the world's poorest populations. Rickettsioses have hardly been studied from a qualitative perspective to show the cultural horizon of the people affected. We aimed to describe the perception of Mayan indigenous farmers about their risk perception for disease transmission...

Chikungunya virus (CHIKV) is an emerging arbovirus whose transmission has already been reported in several countries. Although the majority of individuals acutely infected with CHIKV appear to become asymptomatic, reports showing the occurrence of atypical and severe forms of the disease are increasing. Among them, the neurological and skin manifestations require medical attention. Treatment of CHIKV infection is almost symptomatic. In this sense, we report the case of a 56-years-old man who presented fever, headaches, paresthesia and pain in the right arm with visible red spots on the skin starting 30 days before Hospital admission...

Chikungunya (CHK) fever is a re-emerging RNA viral infection caused by the bite of infected Aedes mosquitoes which presents with a multitude of mucocutaneous manifestations, including a characteristic morbilliform rash, centrofacial pigmentation, aphthae-like lesions, and vesiculobullous lesions sparing mucosae. The majority of these lesions resolve spontaneously and do not require specific therapy. With regular and cyclical outbreaks in many countries for many decades, it is obligatory for dermatologists to be aware of the different skin lesions in the wake of early diagnosis and the need for conservative management...

Chikungunya fever is a mosquito-borne viral disease classically characterized by an acute onset of fever, arthralgia, and skin rash. In this article, we report the acute febrile illness of an adult female with arthropathy and morbilliform eruptions. The patient developed panniculitis lesions on both shins. This report aims to describe an infrequent cutaneous presentation of chikungunya fever.

BACKGROUND: In 2016, there was a massive outbreak of chikungunya in North India. During the epidemic, we observed many neonatal and early infantile cases of chikungunya, with a probable perinatal transmission. METHODS: This retrospective study was carried out in a tertiary care neonatal centre between August 2016 and November 2016. Chikungunya virus (CHIKV) infection was detected and confirmed by reverse transcription-polymerase chain reaction (RT-PCR) and/or serology (anti-CHIKV IgM) in mothers and infants...

Chikungunya fever is a benign, self-limiting, acute viral illness. An epidemic occurred in New Delhi, India, in August and September 2016. We observed many cases with atypical cutaneous features mimicking Stevens-Johnson syndrome and toxic epidermal necrolysis during this epidemic, especially in infants and children. Twenty-one children (13 [61.9%] boys, 8 [38%] girls) presenting with vesico-bullous and necrotic lesions were reviewed. Cutaneous presentation included vesicles and bullae with purpuric macules and necrosis, seen in 16 (76%) patients...

We describe a 3-month-old male infant who presented with acute onset fever, irritability and marked tachycardia. ECG was suggestive of atrial tachycardia. He developed erythematous blanchable skin rash on day 2 of illness, which progressed to vesiculobullous lesions over a few days' time. The child was managed with intravenous adenosine, carefully monitored fluid boluses, oxygen supplementation and close monitoring. Tachycardia improved within 24 hours. Blood for Chikungunya PCR was positive. The child was discharged after 5 days of hospitalisation with bullous lesions evolving into hyperpigmented macules followed by crusts and hypopigmentation by day 10...

INTRODUCTION: Atypical clinical manifestations have been observed in newborns and infants suffering from fever caused by the chikungunya virus. Objective: To describe the cases of fever caused by the chikungunya virus in newborns and infants with atypical mucocutaneous lesions. Materials and methods: We reviewed the clinical records, as well as lab tests and histopathological results, of newborns and infants diagnosed with Chikungunya virus and atypical mucocutaneous lesions in three regional hospitals...

Mosquito-transmitted Sindbis virus (SINV) causes fever, skin lesions and musculoskeletal symptoms if transmitted to man. SINV is the prototype virus of genus Alphavirus, which includes other arthritogenic viruses such as chikungunya virus (CHIKV) and Ross River virus (RRV) that cause large epidemics with a considerable public health burden. Until now the human B-cell epitopes have been studied for CHIKV and RRV, but not for SINV. To identify the B-cell epitopes in SINV-infection, we synthetised a library of linear 18-mer peptides covering the structural polyprotein of SINV, and probed it with SINV IgG-positive and IgG-negative serum pools...

A 47-year-old man with recent travel to the Caribbean was admitted with acute febrileillness associated with arthralgia and skin rash followed by sudden onset of bilateral visual field defects. Funduscopy revealed subtle bilateral paracentral dark lesions nasal to the fovea best seen on near infrared imaging as hyporeflective, wedge-shaped, paracentral macular lesions. Spectral-domain optical coherence tomography (SD-OCT) through the lesions revealed hyperreflective bands at the level of the outer plexiform layer and outer nuclear layer (ONL), with concomitant attenuation of the underlying external limiting membrane (ELM), ellipsoid zone (EZ), and interdigitation zone (IZ)...

Chikungunya virus (CHIKV) is transmitted when infected mosquito probes the host skin. While probing, mosquito saliva is expectorated into host skin along with virus which contains cocktail of molecules having anti-hemostatic and immunomodulatory properties. As mosquito saliva is a critical factor during natural arboviral infection, therefore we investigated mosquito saliva induced cutaneous events that modulate CHIKV infection. The effect of mosquito saliva on CHIKV infection was examined through inoculation of suckling mice subcutaneously with either CHIKV alone or uninfected mosquito bite followed by CHIKV...

Melanin is a canonical and major defense molecule in invertebrates but its role in mammalian immunity remains unexplored. In contrast, several recent studies have highlighted the emerging innate immune activities of human melanin-producing cells which can sense and respond to bacterial and viral infections. Indeed, the skin is a major portal of entry for pathogens such as arboviruses (Chikungunya, Dengue) and bacteria (mycobacterium leprae, Leptospira spirochetes). Melanocytes of the epidermis could contribute to the phagocytosis of these invading pathogens and to present antigens to competent immune cells...

Chikungunya fever, a re-emerging RNA viral infection produces different cutaneous manifestations in children compared to adults. 52 children with chikungunya fever, confirmed by positive IgM antibody test were seen during 2009-2010. Pigmentary lesions were common (27/52) followed by vesiculobullous lesions (16/52) and maculopapular lesions (14/52). Vesiculobullous lesions were most common in infants, although rarely reported in adults. Psoriasis was exacerbated in 4 children resulting in more severe forms. In 2 children, guttate psoriasis was observed for the first time...
