Comparison of Full Outline of Unresponsiveness Score and Glasgow Coma Scale for Assessment of Consciousness in Children With Acute Encephalitis Syndrome.

OBJECTIVE: To correlate the Full outline of unresponsiveness (FOUR) score and Glasgow coma scale (GCS) in the assessment of children with acute encephalitis syndrome (AES). METHODS: This observational study was conducted in the department of pediatrics of a public sector tertiary care center from January, 2019 to March, 2020. All consecutive patients of AES admitted during the study period (n=150) were recruited. Subjects were analyzed using the FOUR score and GCS on admission, and then 12-hourly till discharge/death. Treatment-related and demographic variables were collected and analyzed. Correlation between FOUR score and GCS scores was calculated using spearman correlation coefficient. RESULTS: Positive correlation was observed between the GCS score and the FOUR score (n=0.82; P<0.001). CONCLUSION: FOUR score and GCS were comparable to assess the level of consciousness in patients with AES. The possibility of using FOUR score as an alternative to GCS in children with AES needs to be considered.

Infectious causes of acute encephalitis syndrome hospitalizations in Central India, 2018-20.

BACKGROUND: We enhanced surveillance of hospitalizations of all ages for acute encephalitis syndrome (AES) along with infectious aetiologies, including the Japanese encephalitis virus (JEV). METHODS: From October 2018 to September 2020, we screened neurological patients for AES in all age groups in Maharashtra and Telangana States. AES cases were enrolled at study hospitals along with other referrals and sampled with cerebrospinal fluid, acute and convalescent sera. We tested specimens for non-viral aetiologies viz. leptospirosis, typhoid, scrub typhus, malaria and acute bacterial meningitis, along with viruses - JEV, Dengue virus (DENV), Chikungunya virus (CHIKV), Chandipura virus (CHPV) and Herpes simplex virus (HSV). RESULTS: Among 4977 neurological hospitalizations at three study site hospitals over two years period, 857 (17.2%) were AES. However, only 287 (33.5%) AES cases were eligible. Among 278 (96.9%) enrolled AES cases, infectious aetiologies were identified in 115 (41.4%) cases, including non-viral in 17 (6.1%) cases - leptospirosis (8), scrub-typhus (3) and typhoid (6); and viral in 98 (35.3%) cases - JEV (58, 20.9%), HSV (22, 7.9%), DENV (15, 5.4%) and CHPV (3, 1.1%). JEV confirmation was significantly higher in enrolled cases than referred cases (10.2%) (p < 0.05). However, the contribution of JEV in AES cases was similar in both children and adults. JE was reported year-round and from adjacent non-endemic districts. CONCLUSIONS: The Japanese encephalitis virus continues to be the leading cause of acute encephalitis syndrome in central India despite vaccination among children. Surveillance needs to be strengthened along with advanced diagnostic testing for assessing the impact of vaccination.

An algorithmic approach to identifying the aetiology of acute encephalitis syndrome in India: results of a 4-year enhanced surveillance study.

BACKGROUND: Annual outbreaks of acute encephalitis syndrome pose a major health burden in India. Although Japanese encephalitis virus (JEV) accounts for around 15% of reported cases, the aetiology of most cases remains unknown. We aimed to establish an enhanced surveillance network and to use a standardised diagnostic algorithm to conduct a systematic evaluation of acute encephalitis syndrome in India. METHODS: In this large-scale, systematic surveillance study in India, patients presenting with acute encephalitis syndrome (ie, acute onset of fever with altered mental status, seizure, or both) to any of the 18 participating hospitals across Uttar Pradesh, West Bengal, and Assam were evaluated for JEV (serum and cerebrospinal fluid [CSF] IgM ELISA) per standard of care. In enhanced surveillance, JEV IgM-negative specimens were additionally evaluated for scrub typhus, dengue virus, and West Nile virus by serum IgM ELISA, and for Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, dengue virus, herpes simplex virus, and enterovirus by CSF PCR across five referral laboratories. In 2017, chikungunya and Leptospira serum IgM by ELISA and Zika virus serum and CSF by PCR were also tested. FINDINGS: Of 10 107 patients with acute encephalitis syndrome enrolled in enhanced surveillance between Jan 1, 2014, and Dec 31, 2017, 5734 (57·8%) of 9917 participants with available data were male and 6179 (62·7%) of 9856 were children aged 15 years and younger. Among patients who provided a sample of either CSF or serum in enhanced surveillance, an aetiology was identified in 1921 (33·2%) of 5786 patients enrolled between 2014 and 2016 and in 1484 (34·3%) of 4321 patients enrolled in 2017. The most commonly identified aetiologies were JEV (1023 [17·7%] of 5786 patients), scrub typhus (645 [18·5%] of 3489), and dengue virus (161 [5·2%] of 3124). Among participants who provided both CSF and serum specimens, an aetiology was identified in 1446 (38·3%) of 3774 patients enrolled between 2014 and 2016 and in 936 (40·3%) of 2324 enrolled in 2017, representing a 3·1-times increase in the number of patients with acute encephalitis syndrome with an identified aetiology compared with standard care alone (299 [12·9%]; p<0·0001). INTERPRETATION: Implementation of a systematic diagnostic algorithm in an enhanced surveillance platform resulted in a 3·1-times increase in identification of the aetiology of acute encephalitis syndrome, besides JEV alone, and highlighted the importance of scrub typhus and dengue virus as important infectious aetiologies in India. These findings have prompted revision of the national testing guidelines for this syndrome across India. FUNDING: US Centers for Disease Control and Prevention.

Viral aetiology in paediatric age group patients admitted with acute febrile encephalopathy in Western Rajasthan.

PURPOSE: In this study, we are trying to find out viral aetiology in paediatric age group patients from 1 month to 15 years of age in Western Rajasthan region. METHODS: A total of 105 patients from 1 month to 15 years were recruited into this study. CSF samples were collected and were processed by multiplex real-time PCR for detection of various predefined panels of viral agents. ELISA was also done for all samples for detection of dengue, JE, measles and mumps. RESULTS: A total of 32 samples out of 105 were tested positive for viral agents. Viral aetiology detected in this study were Adenovirus (n â€‹= â€‹2), EBV (n â€‹= â€‹1), HHV-1 (n â€‹= â€‹10), HHV-6 (N â€‹= â€‹5), Parechovirus (n â€‹= â€‹1), Parvovirus B19 (n â€‹= â€‹7), Dengue (n â€‹= â€‹2) and Measles (n â€‹= â€‹1). Mixed infections were also detected, HHV-1 and HHV-6 (n â€‹= â€‹2), HHV-1 and Parvovirus B19 (n â€‹= â€‹1). In 73 patients no viral aetiology could be detected. CONCLUSIONS: Parvovirus B19 is sporadically prevalent in this geographical region. In this study, HHV-6 was also found which has not been reported earlier from India.

Biotin-thiamine responsive basal ganglia disease in the era of COVID-19 outbreak diagnosis not to be missed: A case report.

BACKGROUND: Biotin-thiamine-responsive basal ganglia disease (BTRBGD) is a rare treatable autosomal recessive neurometabolic disorder characterized by progressive encephalopathy that eventually leads to severe disability and death if not treated with biotin and thiamine. BTRBGD is caused by mutations in the SLC19A3 gene on chromosome 2q36.6, encoding human thiamine transporter 2 (hTHTR2). Episodes of BTRBGD are often triggered by febrile illness. CASE REPORT: The patient was 2 years 10 months old male child presented with fever and progressive acute encephalopathy associated with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus infection. MRI revealed bilateral symmetrical high signal involving both basal ganglia and medial thalami which is swollen with central necrosis, initially diagnosed as acute necrotizing encephalomyelitis with increased severity. Genetic analysis revealed BTRBGD. CONCLUSION: BTRBGD requires high index of suspicion in any patient presenting with acute encephalopathy, characteristic MRI findings (that are difficult to differentiate from necrotizing encephalopathy), regardless of the existence of a proven viral infection.

Comparison of 4 weeks versus 12 weeks antiseizure medication for acute symptomatic seizures in children with Acute Encephalitis Syndrome: An open-label, randomized controlled trial.

OBJECTIVE: To compare the proportion of children with seizure recurrence/s during 6-18 months of follow-up among children with acute symptomatic seizures underlying acute encephalitis syndrome (AES) treated with either 4 weeks or 12 weeks of antiseizure medication (ASM). METHODS: Eligible children aged 3 months to 12 years with acute symptomatic seizures underlying AES, receiving a single ASM at 4 weeks of illness, and without seizure recurrence from day 7-28 of illness were included in this comparative, parallel-group assignment, open-label, randomized control study (either 4 weeks or 12 weeks duration). The primary outcome was to compare proportions of children developing seizure recurrence over six months of follow-up. The secondary outcomes were to study seizure recurrence over 12-18 months follow-up and factor(s) associated with seizure recurrence. RESULTS: Of 232 children with AES screened, 60 eligible children were randomized in two groups. Baseline demographics were comparable (except the duration of illness) between the groups. Seizure recurrences at 6, 12 and 18 months were none, two (one in each group, relative risk 1.0, 95% CI 0.06-16.76; p-value >0.99), and six (one and five children in 4 and 12 weeks groups respectively, relative risk 0.17, 95% CI 0.01-1.62; p-value 0.19) respectively. There was no association of seizure recurrences with seizure characteristics, abnormal electroencephalography and neuroradiology. Children with disabilities at randomization had a higher risk of seizure recurrence at 18 months of follow-up (relative risk 7.16, 95% CI 1.1-43.9; p-value 0.049). SIGNIFICANCE: With limitations of the study design, this study provides Class I evidence that a shorter duration (4 weeks) of ASM is comparable with 12 weeks therapy for preventing seizure recurrences in children with AES.

Seasonal abundance of Leptotrombidium deliense, the vector of scrub typhus, in areas reporting acute encephalitis syndrome in Gorakhpur district, Uttar Pradesh, India.

The rickettsial pathogen Orientia tsutsugamushi, causing scrub typhus, has been implicated as a major cause of acute encephalitis syndrome (AES) in many places in India including Gorakhpur district of Uttar Pradesh. Seasonal abundance of the principal vector mite of the pathogen, Leptotrombidium deliense, its animal hosts, and prevalence of infection on them are important attributes in the assessment of outbreaks of the disease. Hence, these aspects were investigated, seasonally, in rural villages of Gorakhpur district, where peak incidence of AES cases were reported. A total of 903 animals (rodents/shrews) was collected using 6484 Sherman traps in eight study villages (14% overall trap rate). A sum of 5526 trombiculid mites comprising 12 species was collected from 676 live rodents/shrews screened. Suncus murinus, the Asian house shrew was the predominant species (67%). Among trombiculids, the principal vector mite, L. deliense, was predominant (64.7%) and its infestation index (i.e., average number of chiggers per host animal) was 5.3. The L. deliense infestation index was higher during July to November with a peak in October. Out of 401 animal sera samples screened, 68% were positive for antibodies against O. tsutsugamushi. Of 465 blood samples tested by nested PCR, seven were positive for the 56 kDa gene of O. tsutsugamushi. In conventional PCR, 41 out of 265 samples were positive for the 60 kDa groEL gene of O. tsutsugamushi. Among the 5526 mite samples, tested as 352 pools through nested PCR, four pools were positive for 56 kDa gene. Phylogenetic analysis of 56 and 60 kDa genes confirmed circulation of Karp and TA678 (rodents) and TA678 (mite) serotypes of O. tsutsugamushi in Gorakhpur. Peak incidence of AES in Gorakhpur district occurs during the rainy season (July-October), coinciding with the peak abundance of L. deliense. These results indicate involvement of L. deliense as the vector mite transmitting the scrub typhus pathogen O. tsutsugamushi to humans in the rural areas of Gorakhpur district, India.

Molecular Detection and Genetic Characterization of Orientia tsutsugamushi from Hospitalized Acute Encephalitis Syndrome Cases During Two Consecutive Outbreaks in Eastern Uttar Pradesh, India.

Background: Seasonal outbreaks of acute encephalitis syndrome (AES) have been reported especially in the pediatric population with a high case fatality rate in Eastern Uttar Pradesh, India. Orientia tsutsugamushi (OT) is a causative agent of scrub typhus that has been recently identified as a major cause of AES. However, the specific genotypes of OT responsible for AES cases of this region are not known. Therefore, the present study was undertaken to understand the molecular epidemiology of OT prevailing in the AES endemic Eastern Uttar Pradesh region of India. Methods: The study was conducted on 2529 hospitalized AES cases from August 2016 to December 2017. The presence of antibodies against OT from cerebrospinal fluid (CSF) and serum samples were tested using OT IgM enzyme-linked immunosorbent assay (ELISA), whereas OT DNA was tested from whole blood and CSF specimens targeting the partial gene of 56 kDa using nested PCR. Phylogenetic analysis was conducted with sequences (n = 241) generated in this study. Findings: Among the studied AES cases, 50% were found positive for antibodies against OT, whereas 37% of cases were positive for OT DNA. The genetic analysis study revealed that Gilliam (93.8%) is the prevailing genotype of OT followed by Karp (6.16%) genotype in AES cases. Furthermore, the Gilliam strains of this study showed they were >99% identical to earlier reported Gilliam strains from AES cases. Conclusion: We observed the presence of two main OT genotypes in AES cases, among which the majority of OT genotypes fall under the Gilliam clade. The understanding of predominant genotype will be beneficial for its future implications in vaccine development strategies and the development of rapid diagnostic tests.

Infant with right hemiplegia due to acute encephalopathy with biphasic seizures and late reduced diffusion (AESD): A case report.

RATIONALE: Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is a condition characterized by biphasic convulsions and disturbance of consciousness. In Japan, the most common pediatric cases of acute encephalopathy are associated with infection. AESD usually occurs in early childhood, with the characteristic magnetic resonance imaging (MRI) appearance called "bright tree appearance." The disease often has neurological sequelae and interferes with the schooling of children and their activities of daily living; however, there are few clinical case reports of hemiplegia caused by AESD. PATIENT CONCERNS: A case with right-sided hemiplegia due to AESD in an 11-month-old girl who was followed up to 30 mo of age. DIAGNOSES: The patient was diagnosed with overlap AESD and hemiconvulsion-hemiplegia-epilepsy syndrome (HHE syndrome), based on the clinical course and imaging findings. DNA tests of her blood and cerebrospinal fluid revealed the presence of human herpesvirus 6. INTERVENTIONS: Pharmacotherapy and rehabilitation therapy. OUTCOME: Gross motor function has recovered considerably, but she had a mild developmental delay at 30 mo old. LESSONS: Hemiplegia due to AESD was extremely rare, and appropriate rehabilitation treatment resulted in recovery of physical function. However, as mild developmental delay was observed, the patient was referred to a specialized facility before entering school.

Health system preparedness & community participation in Japanese encephalitis/acute encephalitis syndrome (JE/AES) prevention in a tribal district of Odisha, India.

BACKGROUND & OBJECTIVES: Japanese encephalitis/acute encephalitis syndrome (JE/AES) is one of the major zoonotic arbodiseases that has a significant effect on human and animal health. Though many studies have been published on the epidemiology and transmission mechanisms of JE/AES, but there is little evidence on health system preparedness, including community-based engagement. This study was undertaken to explore a multi-stakeholder perspective on health system preparedness for the prevention of JE/AES in a tribal district of Odisha, India. METHODS: This study was conducted at Malkangiri district of Odisha. A total of nine focus group discussions (FGDs) among women having under-five children, community volunteers, and community health workers (CHWs), and 20 in-depth-interviews (IDIs) among community leaders, healthcare providers, and programme managers were conducted. The FGDs and IDIs were digitally recorded, transcribed, translated and analysed using content analysis approach. RESULTS: Health system preparedness for the prevention of JE/AES was improved, including effective vector management, implementation of the surveillance system, and vaccination programme. The JE vaccine was introduced under Universal Immunization Programme in Odisha in 2016. Behavioural Change Communication activities were provided with the support of community volunteers on Village Health Nutrition and Sanitation Day (VHNSD) under Gaon Kalyan Samiti (GKS) platforms. The CHWs were actively involved in vector management and raising sanitation and hygiene awareness. INTERPRETATION & CONCLUSIONS: Community participation and coordination between different stakeholders have a significant impact on the successful implementation of the programme. It was suggested that there was a need for a sustainability approach to active participation, orientation and capacity building training among CHWs and community volunteers to successfully implement the programme.

Investigations of seasonal outbreaks of acute encephalitis syndrome due to Orientia tsutsugamushi in Gorakhpur region, India: A One Health case study.

Gorakhpur division consisting of Gorakhpur and neighboring districts Deoria, Kushinagar and Maharajganj in Uttar Pradesh, India, have been witnessing seasonal outbreaks of acute encephalitis syndrome (AES) among children for the last three decades. Investigations conducted during 2005 identified Japanese encephalitis (JE) virus as an aetiology of AES. With the introduction of JE vaccination and other control strategies, the incidence of JE in the region declined, however, outbreaks of acute febrile illness with neurological manifestations continued to occur. Subsequent investigations identified Orientia tsutsugamushi, as the major aetiology of AES outbreaks in the region. This review details clinical, epidemiological, animal and entomological investigations conducted for AES due to O. tsutsugamushi during 2015 and 2017 in Gorakhpur region. Surveillance of acute febrile illness among children attending peripheral health facilities identified scrub typhus as an important aetiology of febrile illness during monsoon and post-monsoon months. Population-based serosurveys indicated high endemicity of scrub typhus. Entomological studies demonstrated natural infection of O. tsutsugamushi in small animal hosts and vector mites. Children acquired this infection through recent exposure to outdoor environment, while playing, or visiting fields or defecating in open fields. A few of the children with scrub typhus progress to develop CNS manifestations. Hence, early administration of appropriate antibiotics is crucial in preventing progression of AFI due to scrub typhus to AES. The investigations conducted by the multi-disciplinary team helped understand the transmission dynamics of scrub typhus in Gorakhpur division and recommend strategies for its control.

Association of leptospirosis and scrub typhus in acute encephalitis syndrome in a tertiary care hospital in Odisha, India.

BACKGROUND: Acute encephalitis syndrome (AES) is a major public health concern in India, causing febrile illness principally associated with viral infection. Bacteria-like scrub typhus and leptospirosis also cause acute febrile illness. Therefore, this study was conceived to address the possible etiological agents contributing to sporadic AES in a tertiary care center in Odisha, India. METHOD: This was a prospective hospital-based study that enrolled 92 consecutive patients with clinically diagnosed AES whose blood/cerebrospinal fluid samples were tested for IgM antibodies to dengue, Japanese encephalitis (JE), herpes simplex virus (HSV), Epstein-Barr virus (EBV), leptospirosis and scrub typhus. RESULTS: Viral antibodies to dengue were detected in three (3.26%) cases, HSV1 in four (4.34%) and HSV2 in three (3.26%) cases. Significantly, antibodies to EBV in 22 (23.591%) and to JE in 27 (29.34%) cases were detected. Notably, 30 (32.60%) and 11(12.0%) of patients had IgM antibodies to leptospirosis and scrub typhus, respectively. CONCLUSION: This observation indicates an association of leptospirosis and scrub typhus infection in sporadic cases of AES, besides other viruses.

Is the Frontal Lobe the Primary Target of SARS-CoV-2?

Acute delirium and other neuropsychiatric symptoms have frequently been reported in COVID-19 patients and are variably referred to as acute encephalopathy, COVID-19 encephalopathy, SARS-CoV-2 encephalitis, or steroid-responsive encephalitis. COVID-19 specific biomarkers of cognitive impairment are currently lacking, but there is some evidence that SARS-CoV-2 could preferentially and directly target the frontal lobes, as suggested by behavioral and dysexecutive symptoms, fronto-temporal hypoperfusion on MRI, EEG slowing in frontal regions, and frontal hypometabolism on 18F-FDG-PET imaging. We suggest that an inflammatory parainfectious process targeting preferentially the frontal lobes (and/or frontal networks) could be the underlying cause of these shared clinical, neurophysiological, and imaging findings in COVID-19 patients. We explore the biological mechanisms and the clinical biomarkers that might underlie such disruption of frontal circuits and highlight the need of standardized diagnostic procedures to be applied when investigating patients with these clinical findings. We also suggest the use of a unique label, to increase comparability across studies.

Rapid and severe neurologic deterioration due to influenza associated encephalopathy in a healthy child.

Rapid neurologic deterioration is rare in healthy school age children, particularly in the absence of trauma or toxic exposure. Hemorrhagic or ischemic stroke, infectious etiologies and metabolic causes must be emergently considered. We present the clinical details of a previously well child with two days of mild viral symptoms who progressed from playful and active to severe neurologic injury over the course of eight hours.

Basal Ganglia Disease Mimicking Acute Encephalitis Syndrome Among Infants of Bodo Tribe, Assam.

We conducted a review of hospital records of infants with acute encephalitis syndrome with bilateral symmetrical basal ganglia infarcts, between 2011-2015, at a single center in Assam. Thiamine (as part of multivitamin injection) was used in the treatment of 23 infants and not used in 27; Only 1 (3.7%) infant died in the former group and 20 infants (86.9%) died in the latter [RR (95% CI) 0.04 (0.006,0.29); P<0.001). Two infants on follow-up had normal development, both in the thiamine group. The study suggests the possibility of subclinical thiamine deficiency, mitochondrial diseases, or SLC19A3 gene mutation in this population.

The Outbreaks of Acute Encephalitis Syndrome in Uttar Pradesh, India (1978-2020) and Its Effective Management: A Remarkable Public Health Success Story.

INTRODUCTION: Acute encephalitis syndrome (AES) is a major public health enigma in India and the world. Uttar Pradesh (UP) is witnessing recurrent and extensive seasonal AES outbreaks since 1978. Government of India and UP state government have devised various mitigation measures to reduce AES burden and AES associated mortality, morbidity and disability in Uttar Pradesh. The aim of this study was to describe the public health measures taken in order to control seasonal outbreaks of AES in UP between 1978 and 2020. METHODS: We used literature review as a method of analysis, including the Indian government policy documents. This review utilized search engines such as PubMed, Google Scholar, Research Gate, Cochrane, Medline to retrieve articles and information using strategic keywords related to Acute Encephalitis Syndrome. Data was also collected from progress reports of government schemes and websites of Indian Council of Medical Research (ICMR), National Vector Borne Disease Control Programme (NVBDCP) and Integrated Disease Surveillance Programmes (IDSP). RESULTS: The incidence of AES cases in UP have declined from 18.2 per million population during 2005-2009 to 15 per million population during 2015-2019 [CI 12.6-20.6, P-value < 0.001] and case fatality rate (CFR) reduced from 33% during 1980-1984 to 12.6% during 2015-2019 [CI 17.4-30.98, P-value < 0.001]. AES incidence was 9 (2019) and 7 (2020) cases per million populations respectively and CFR was 5.8% (2019) and 5% (2020). This decline was likely due to active surveillance programs identifying aetiological agents and risk factors of AES cases. The identified etiologies of AES include Japanese encephalitis virus (5-20%), Enterovirus (0.1-33%), Orientia tsutsugamushi (45-60%) and other viral (0.2-4.2%), bacterial (0-5%) and Rickettsial (0.5-2%) causes. The aggressive immunization programs against Japanese encephalitis with vaccination coverage of 72.3% in UP helped in declining of JE cases in the region. The presumptive treatment of febrile cases with empirical Doxycycline and Azithromycin (EDA) caused decline in Scrub Typhus-AES cases. Decrease in incidence of vector borne diseases (Malaria, Dengue, Japanese Encephalitis and Kala Azar) i.e., 39.6/100,000 population in 2010 to 18/100,000 population in 2017 is highlighting the impact of vector control interventions. Strengthening healthcare infrastructure in BRD medical college and establishment of Encephalitis Treatment Centre (ETC) at peripheral health centres and emergency ambulance services (Dial 108) reduced the referral time and helped in early treatment and management of AES cases. The AES admissions increased at ETC centres to 60% and overall case fatality rate of AES declined to 3%. Under clean India mission and Jal Jeevan mission, proportion of population with clean drinking water increased from 74.3% in 1992 to 98.7% in 2020. The proportion of household having toilet facilities increased from 22.9% in 1992 to 67.4% in 2020. Provisions for better nutritional status under state and national nutrition mission helped in reducing the burden of stunting (52%) and wasting (53.4%) among under five children in 1992 to 38.8% (stunting) and 36.8% (wasting) in year 2018. These factors have all likely contributed to steady AES decline observed in UP. CONCLUSION: There is a recent steady decline in AES incidence and CFR since implementation of intensive AES surveillance system and JE immunization campaigns which is highlighting the success of interventions made by central and state government to control seasonal AES outbreaks in UP. Currently, AES incidence is 9 cases per million population (in year 2019) and mortality is 5.8%.

Spotted Fever Group Rickettsiae among Children with Acute Febrile Illness, in Gorakhpur, India.

Seasonal outbreaks of acute encephalitis syndrome have been occurring in Gorakhpur division in the Indian state of Uttar Pradesh during monsoon and post-monsoon months. Orientia tsutsugamushi was identified as the major aetiology of these outbreaks. Orientia tsutsugamushi was also identified as one of the important aetiology of febrile illness among children attending peripheral health facilities. The present study was undertaken to detect antibodies against spotted fever group rickettsiae (SFGR) and typhus group rickettsiae (TGR) among children with acute febrile illness presenting at peripheral health facilities in Gorakhpur district. Of the 224 blood samples tested, SFGR infection was detected in 13 (6%) patients. None of the samples tested positive for TGR.
