RESUMEN
BACKGROUND: COVID-19 pandemic resulted in widespread and devastating physical, emotional, societal, and economic repercussions among workers in India. OBJECTIVES: To evaluate the impact of COVID-19 and to understand the challenges faced and coping mechanism adopted among fishermen community from the coastal area of Karnataka. METHODOLOGY: This community-based mixed-methods study included participants from a coastal Karnataka fishermen's community. Questionnaire based personal interviews collected information on sociodemographics, COVID-19 diagnosis, treatment, and related costs, COVID-19-appropriate behavior and were screened using DASS-21. Focus group discussions and key informant interviews were conducted to acquire qualitative data. RESULTS: Quantitative data collection involved 107 participants, predominantly males [70.1%], aged between 46-60 years [37.4%] and low socioeconomic status [79.4%]. Among 107, 51 participants reported to have probable COVID-19 symptoms. Around 11% had tested for COVID-19 and two were admitted in hospital with mean hospital stay of seven days. According to DASS-21, 20.6%, 15.9% and 9.3% of participants screened positive for depression, anxiety and stress respectively. Nearly one third of the participants were found to have significant socioeconomic impact.Major challenges faced included loss of livelihood, inaccessibility to health care, repayment of loans, stigma related to COVID-19 and meeting educational expenses of children with one dropping out of college. Activities of local self-help groups in the community and grass root level marketing strategies to sell fish were highly successful in mitigating the impact as a community. CONCLUSION: COVID-19 had a significant impact on fishermen community and implies a need for better pandemic and disaster preparedness strategies in the community.
RESUMEN
Experiences in early childhood form the bedrock of future human potential. In impoverished settings, structured early childhood education (ECE) in preschool years can augment overall childhood and later human abilities. The current study evaluates preschool learning exposure and childhood cognition, using longitudinal follow-up of a community-based birth cohort in Vellore, south India. The birth cohort study site in Vellore recruited 251 newborns between 2010 and 2012 from dense urban settlements and further followed up into childhood. Preschool enrolment details were obtained from parents. Childhood cognition was assessed by Weschler's preschool primary scale of intelligence (WPPSI) and Malin's intelligence scale for Indian Children (MISIC) at 5 and 9 years of age respectively. Bivariate and multivariate regression analyses were performed with adjustments for socio-economic status (SES), maternal education, stunting status and home environment. Out of 251 new-borns recruited into the MAL-ED birth cohort, 212 (84.46%) and 205 (81.7%) children were available for the 5 year and 9 year follow-up respectively. At 5 years, structured ECE of 18 to 24 months duration was significantly associated with higher cognition scores, with the highest increase in processing speed [ß: 19.55 (11.26-27.77)], followed by full-scale intelligence [ß: 6.75 (2.96-10.550)], even after adjustments for SES, maternal cognition, home factors and early childhood stunting status. Similarly adjusted analysis at 9 years showed that children who attended 1.5-2 years of structured ECE persisted to have higher cognition, especially in the performance domain [ß: 8.82 (2.60-15.03)], followed by the full-scale intelligence [ß: 7.24 (2.52-11.90)]. Follow-up of an Indian birth cohort showed that structured ECE exposure was associated with better school entry cognition as well as mid-childhood cognition. Strengthening ECE through a multi-pronged approach could facilitate to maximize cognitive potential of human capital.

Women from low- and middle-income countries face challenges in accessing and utilising quality healthcare. Technologies can aid in overcoming these challenges and the present scoping review is aimed at summarising the range of technologies used by women and assessing their role in enabling Indian women to learn about and access healthcare services. We conducted a comprehensive search from the date of inception of database till 2022 in PubMed and Google Scholar. Data was extracted from 43 studies and were thematically analysed. The range of technologies used by Indian women included integrated voice response system, short message services, audio-visual aids, telephone calls and mobile applications operated by health workers. Majority of the studies were community-based (79.1%), from five states (60.5%), done in rural settings (58.1%) and with interventional design (48.8%). Maternal and child health has been the major focus of studies, with lesser representation in domains of non-communicable and communicable diseases. The review also summarised barriers related to using technology - from health system and participant perspective. Technology-based interventions are enabling women to improve awareness about and accessibility to healthcare in India. Imparting digital literacy and scaling up technology use are potential solutions to scale-up healthcare access among women in India.

BACKGROUND: In 2017, more than half the cases of typhoid fever worldwide were projected to have occurred in India. In the absence of contemporary population-based data, it is unclear whether declining trends of hospitalization for typhoid in India reflect increased antibiotic treatment or a true reduction in infection. METHODS: From 2017 through 2020, we conducted weekly surveillance for acute febrile illness and measured the incidence of typhoid fever (as confirmed on blood culture) in a prospective cohort of children between the ages of 6 months and 14 years at three urban sites and one rural site in India. At an additional urban site and five rural sites, we combined blood-culture testing of hospitalized patients who had a fever with survey data regarding health care use to estimate incidence in the community. RESULTS: A total of 24,062 children who were enrolled in four cohorts contributed 46,959 child-years of observation. Among these children, 299 culture-confirmed typhoid cases were recorded, with an incidence per 100,000 child-years of 576 to 1173 cases in urban sites and 35 in rural Pune. The estimated incidence of typhoid fever from hospital surveillance ranged from 12 to 1622 cases per 100,000 child-years among children between the ages of 6 months and 14 years and from 108 to 970 cases per 100,000 person-years among those who were 15 years of age or older. Salmonella enterica serovar Paratyphi was isolated from 33 children, for an overall incidence of 68 cases per 100,000 child-years after adjustment for age. CONCLUSIONS: The incidence of typhoid fever in urban India remains high, with generally lower estimates of incidence in most rural areas.

Background Experiencing poor mental health during adolescence predisposes an individual to psychiatric morbid conditions in adulthood. We estimated the prevalence of psychological morbidity and its associated factors, among school-going adolescents in higher secondary schools of urban Puducherry. Methods We did this cross-sectional study among adolescents studying in classes 11 and 12 from selected schools of urban Puducherry, including one government and three private schools. Study tools used were the General Health Questionnaire-12 and Perceived Stress Scale-10 to assess psychological morbidity and perceived psychological stress in adolescents, respectively. Risk factors in academic, environmental, personal and health-related domains were captured using a structured questionnaire. Study questionnaires were self-administered by the participants in classrooms. Bivariate and multivariate analyses were done to identify risk factors for psychological morbidity. Results Of the 820 adolescents surveyed, the prevalence of psychological morbidity was 25.4% (95% CI 22.4- 28.5). Academic factors such as reporting peer pressure for academic performance and lack of extracurricular activities at school were associated with psychological morbidity. Among health-related factors, adolescents who reported having difficulty in coping with pubertal changes, being worried about their physical appearance, reporting substance abuse and experiencing sleep disturbances had greater chances of having screened with psychological morbidity. Of note, adolescents with psychological stress had 2.5 times higher chances of having psychological morbidity. Conclusions We estimated that 1 in 4 school-going adolescents in urban Puducherry suffered psychological morbidity. Reducing the academic burden and advocating health promotion through a life skills approach may improve mental wellness in Indian adolescents.

BACKGROUND: Human resilience is dynamic and generated through myriad interactions starting from early childhood. Resilience can improve quality of life and longevity. OBJECTIVE: The current analysis evaluates childhood resilience at 9 years of age and its associations with concurrent cognition and early childhood factors, using longitudinal follow-up of a community birth cohort in Vellore, south India. METHODS: Resilience was assessed using the Child and Youth Resilience Measure and cognition utilizing the Malin's Intelligence Scale for Indian Children. Early childhood variables included growth stunting, maternal depression scores, home environment scores, and socio-economic status (SES) at 2 years of age. Statistical evaluation included bivariate analysis with further multi-variate regression for each resilience domain and the total resilience score. FINDINGS: Out of 251 newborns recruited into the original birth cohort, 205 (81.7%) children were available for the 9-year follow-up. Mean (SD) scores in individual, caregiving, and context domains of resilience were 26.34 (3.2), 19.52 (1.6), and 20 (1.8) respectively. Individual resilience domain was associated with verbal cognition scores at 9 years of age (0.07, p = 0.019) and total home environment scores (0.16, p = 0.027) at 2 years of age, when adjusted for stunting, maternal depression, and SES. The total resilience score was associated only with concurrent verbal intelligence (0.08, p = 0.026) after adjustment with early childhood factors. Analysis of individual home environment factors showed that daily stimulation was associated with the individual domain of resilience. CONCLUSIONS: Follow-up of an Indian birth cohort showed that in addition to concurrent cognitive abilities, childhood resilience was related to early childhood stimulating home environment. Promoting optimal stimulating home environments in low-resource settings to nurture holistic childhood development including mental health is essential.
RESUMEN
We report an outbreak of typhoid fever between April and June 2019 in the Surveillance for Enteric Fever in India cohort, a pediatric cohort from four contiguous semi-urban settlements of Vellore in South India. This cohort of children 6 months to 15 years of age was under surveillance from October 2017 to December 2019. A clustering of typhoid cases in the cohort was noted with reference to time, place, and person. The overall typhoid attack rate in the cohort was 0.9%, with the highest attack rate of 1.7% being documented in one of the four areas. The rate of hospitalization and complications in children who were typhoid positive during the outbreak was 28% and 2%, respectively. Given the background of suboptimal water, sanitation, and hygiene, and the risk of typhoid fever outbreaks in these settings, it is imperative that a typhoid vaccine be considered for introduction as a pragmatic preventive approach.

BACKGROUND: Millions of children worldwide especially in the Asian subcontinent are vulnerable to early childhood stunting. There are contradictory reports of the association between catch-up growth in childhood and school age cognition. METHODS: A community-based birth cohort recruited between 2010 and 2012 from urban slums in Vellore, India was followed up until 9 years of age. From regular anthropometric measurements, stunting status for each individual child was calculated at 2, 5 and 9 years. Cognition was assessed at 9 years of age using the Malin's Intelligence Scale for Indian Children (MISIC). Children were divided into groups based on stunting at each time point as well as catch-up growth, and a regression model was utilised to evaluate their association with cognition at 9 years. RESULTS: Among 203 children included in this analysis, 94/203 (46.31%) children were stunted at 2 years of age, of whom 39.36% had a catch-up growth at 5 years of age, and 38.30% at 9 years. Around 10% of the cohort remained stunted at all time points. In the multivariable analysis, children who were stunted at 2, 5 and 9 years had a significantly lower verbal and total intelligence quotient (IQ) scores by 4.6 points compared to those who were never stunted. Children with catch up growth following stunting at 2 years had higher cognition scores than those who were persistently stunted throughout the childhood. CONCLUSIONS: This study showed persistent stunting in childhood was associated with lowering of 4-5 IQ points in childhood cognition at 9 years of age. Recovery from early life stunting in children with catch up growth prevented further lowering of cognition scores in these children compared to persistently stunted children. Nutritional supplementation during late infancy and early toddlerhood in addition to continuing nutritional supplementation programmes for preschool and school children can improve childhood stunting and cognitive abilities in vulnerable populations.

Cohorte de NacimientoRESUMEN
BACKGROUND: Pregnancy and early infancy are considered to be the vulnerable phases for severe influenza infection causing morbidity and mortality. Despite WHO recommendations, influenza is not included in the immunization programs of many low- and middle-income countries. This systematic review is aimed at identifying barriers and facilitators for maternal influenza vaccination amongst the perinatal women and their health care providers in low- and middle-income countries. METHODS: We selected 11 studies from the 1669 records identified from PubMed, CABI, EMBASE and Global Health databases. Studies related to both pandemic and routine influenza vaccination and studies conducted amongst women in the antenatal as well as postnatal period were included. Both qualitative, quantitative, cross-sectional and interventional studies were included. RESULTS: Knowledge about influenza disease, perception of the disease severity during pregnancy and risk to the foetus/newborn and perceived benefits of influenza vaccination during pregnancy were associated with increased uptake of influenza vaccination during pregnancy. Recommendation by health care provider, vaccination in previous pregnancy and availability of vaccine in public health system facilitated vaccine uptake. High parity, higher education, vaccination in the later months of pregnancy, less than 4 antenatal visits, concerns about vaccine safety and negative publicity in media were identified as barriers for influenza vaccination. Lack of government recommendation, concerns about safety and effectiveness and distrust in manufacturer were the barriers for the healthcare providers to recommend vaccination. CONCLUSION: While availability of influenza vaccine in public health system can be a key to the success of vaccine implementation program, increasing the awareness about need and benefits of maternal influenza vaccination amongst pregnant women as well as their health care providers is crucial to improve the acceptance of maternal influenza vaccination in low and middle-income countries.

BACKGROUND: Early childhood developmental pattern analyses not only project future cognition potential, but also identify potential risks for possible intervention. The current study evaluates developmental trends in the first 3 years of life and their predictors in a low and middle income country setting. METHODS: Trends of early childhood development at 6, 15, 24 and 36 months of age and their predictors were explored in a longitudinal community-based birth cohort study in an urban slum in Vellore, South India. Development was assessed using the Bayley Scales of Infant and Toddler Development-III (BSID-III). RESULTS: The birth cohort enrolled 251 children with 94, 91, 91 and 87% follow-up at 6, 15, 24 and 36 months respectively. Child development domains of cognition, language, motor and social skills showed a significant decline in scores between 6 and 36 months of age. Higher socioeconomic position (SEP) and nurturing home environment contributed to increase in cognition scores by 1.9 and 0.9 units respectively. However, stunting caused a decline in cognition scores by 1.7 units. Higher maternal cognition, higher SEP, and caregiver responsivity positively contributed to language change over time, while higher maternal depression contributed negatively. An enriching home environment, growth parameters and blood iron status had positive association with change in motor skills. CONCLUSIONS: A triple intervention plan to enhance home environment and nurturance, early childhood nutrient supplementation, and maternal education and well-being might prevent child developmental decline in high risk settings.

BACKGROUND: Head circumference (HC) measurement is routinely not performed in early childhood and there is conflicting information about its utility in literature. The current study analyses the association between HC at two years of age and cognition at two and five years of age. METHODS: A community based birth-cohort recruited between 2010 and 2012 was followed up till five years of age in an urban slum in Vellore, India. Children were recruited at birth after informed parental consent by consecutive sampling using eligibility criteria of healthy new-born, singleton pregnancy and family's availability in the study area during follow-up. HC measured at two years of age was used as the exposure variable to calculate association with cognition at both two and five years of age. Cognitive domain of Bayley scale of infant development was used at two years of age and Wechsler Preschool Primary Scales of Intelligence at five years. RESULTS: Of the 251 enrolled children, 138 (55%) were girls and 71 (30%) belonged to lower socioeconomic status. At 2 years, 8.81% of children had HC < - 3SD. Compared to children with HC z-scores ≥ - 2 SD, those with measurements < - 3 SD had a lower cognition scores by - 2.21 [95% CI: - 3.87 - -0.56] at 2 years. Also, children with HC < - 3 SD at two years scored significantly lower scores in cognitive domains of verbal, - 7.35 [95% CI: - 11.78 - -2.92] and performance, - 7.07 [95% CI: - 11.77 - -2.36] intelligence at five years. CONCLUSIONS: This study showed that smaller HC at 2 years of age was negatively associated with cognition at both 2 and 5 years of age. Early childhood HC measurements can be utilised as a cheaper screening tool to identify children at risk in LMIC settings. Further studies can confirm these findings in diverse settings.

BACKGROUND: Typhoid fever causes substantial morbidity and mortality in low- and middle-income countries. We conducted a case-control study in Vellore, southern India, to understand risk factors for transmission of typhoid. METHODS: From April 2018 to October 2019, households of blood culture-confirmed typhoid cases that occurred within a fever surveillance cohort aged 6 months-15 years, and controls matched for age, sex, geographic location, and socioeconomic status, were recruited. Information on risk factors was obtained using standard questionnaires. Household and environmental samples were collected for detection of Salmonella Typhi using real-time polymerase chain reaction. Multivariable analysis was used to evaluate associations between risk factors and typhoid. RESULTS: One hundred pairs of cases and controls were recruited. On multivariable regression analysis, mothers eating food from street vendors during the previous week (odds ratio [OR]â =â 2.04; 95% confidence interval [CI], 1.03-4.12; Pâ =â .04) was independently associated with typhoid, whereas treatment of household drinking water (ORâ =â 0.45; 95% CI, 0.25-0.80; Pâ =â .007) was protective. There was no significant difference in S Typhi detection between the environmental samples from case and control households. CONCLUSIONS: Street-vended food is a risk factor for typhoid in densely populated urban communities of Vellore. Improved sanitation facilities and awareness about point-of-use water treatment are likely to contribute to typhoid control.

BACKGROUND: Typhoid is known to be heterogenous in time and space, with documented spatiotemporal clustering and hotspots associated with environmental factors. This analysis evaluated spatial clustering of typhoid and modeled incidence rates of typhoid from active surveillance at 4 sites with child cohorts in India. METHODS: Among approximately 24 000 children aged 0.5-15 years followed for 2 years, typhoid was confirmed by blood culture in all children with fever >3 days. Local hotspots for incident typhoid cases were assessed using SaTScan spatial cluster detection. Incidence of typhoid was modeled with sociodemographic and water, sanitation, and hygiene-related factors in smaller grids using nonspatial and spatial regression analyses. RESULTS: Hotspot households for typhoid were identified at Vellore and Kolkata. There were 4 significant SaTScan clusters (P < .05) for typhoid in Vellore. Mean incidence of typhoid was 0.004 per child-year with the highest incidence (0.526 per child-year) in Kolkata. Unsafe water and poor sanitation were positively associated with typhoid in Kolkata and Delhi, whereas drinking untreated water was significantly associated in Vellore (P = .0342) and Delhi (P = .0188). CONCLUSIONS: Despite decades of efforts to improve water and sanitation by the Indian government, environmental factors continue to influence the incidence of typhoid. Hence, administration of the conjugate vaccine may be essential even as efforts to improve water and sanitation continue.

BACKGROUND: Blood culture, despite low sensitivity, is the gold standard for enteric fever diagnosis. Understanding predictors of blood culture positivity may help design strategies to optimize enteric fever diagnosis. METHODS: A cohort of 6760 children aged 0.5-15 years was followed for 3 years for enteric fever with blood cultures in an automated system, for fevers >3 days. Factors affecting test positivity in fevers and participant-level predictors for culture refusals were analyzed using regression models. RESULTS: Overall, 6097 suspected typhoid/paratyphoid fever (STF) episodes were reported, of which 5703 (93.5%) STFs had sampling for blood cultures, with 394 (6.5%) refusals. Salmonella enterica serovar Typhi/Paratyphi positivity was culture-confirmed in 3.8% (218/5703) of STF episodes. Older children (odds ratio [OR], 1.96 [95% CI, 1.39-2.77]), larger blood volume inoculated (OR, 2.82 [95% CI, 1.71-4.66]), higher temperatures during fever (OR, 3.77 [95% CI, 2.89-4.91]), and fevers diagnosed as suspected typhoid or acute undifferentiated fever (OR, 6.06 [95% CI, 3.11-11.78]) had a higher probability of culture positivity. Antibiotics before culture did not decrease culture positivity. Blood culture refusals were higher for children from wealthier households or with milder illness. CONCLUSIONS: Performing blood cultures in older children with fever, especially those fevers with toxic presentation and increasing blood volume for inoculation are strategies to improve enteric fever detection in surveillance settings.

BACKGROUND: Acute febrile illness in children is frequently treated with antibiotics. However, the inappropriate use of antibiotics has led to the emergence of multidrug-resistant pathogens. METHODS: We measured use of antibiotics for fever in 4 pediatric cohorts that were part of the Surveillance for Enteric Fever in India (SEFI) network. In this network, 24 062 children were followed up weekly, capturing information on fever and other morbidity between October 2017 and December 2019. RESULTS: An antibiotic was given in 27 183 of the 76 027 (35.8%) episodes of fever. The incidence of fever-related antibiotic use was 58.0 (95% confidence interval [CI], 57.2-58.6) per 100 child-years. The median time to initiation of antibiotics was 4 days, and in 65% of those who received an antibiotic it was initiated by the second day. Antibiotics were continued for <3 days in 24% of the episodes. Higher temperature, younger age, male sex, joint family, higher education, internet access, and availability of personal conveyance were associated with antibiotic treatment for fever. CONCLUSIONS: In developing countries where antibiotic use is not regulated, broad-spectrum antibiotics are initiated early, and often inappropriately, in febrile illness. Frequent and inappropriate use of antibiotics may increase risk of antimicrobial resistance.

BACKGROUND: Children suffer the highest burden of the typhoid fever, with a considerable proportion shedding Salmonella Typhi in stool, potentially resulting in transmission of S Typhi. METHODS: We enrolled 70 children with blood culture-confirmed typhoid fever (index cases), from 63 households, during community-based fever surveillance in India. The index cases and their household contacts were followed up with stool samples at multiple time points over 3 weeks and 1 week, respectively. S Typhi was detected using quantitative real-time polymerase chain reaction. RESULTS: Fifteen of 70 (21.4%) children with culture-confirmed typhoid fever shed S Typhi in stool after onset of fever. Ten of 15 children shed S Typhi for a median of 11.5 (range, 3-61) days from the day of completion of antibiotics. Of 172 household contacts from 56 of the 63 index case households, 12 (7%) contacts in 11 (19.6%) households had S Typhi in stool. Five of the 12 contacts who were shedding S Typhi were asymptomatic, whereas 7 reported recent fever. CONCLUSIONS: One in 5 children with typhoid fever shed S Typhi, with shedding persisting even after antibiotics. One in 5 households had at least 1 contact of the child shedding S Typhi, highlighting potential concurrent typhoid infections in households in settings with poor water and sanitation.

BACKGROUND: Primary data on causes and costs of hospitalization are necessary for costing and cost-effectiveness analysis. Data on incidence and causes of hospitalization and consequent expenses among Indian children are limited. METHODS: A cohort of 6000 children aged 0.5-15 years residing in urban Vellore was followed for 3 years, under the Vellore Typhoid Study, 2016-2017, and later under the Surveillance for Enteric Fever project, 2017-2019. Data on hospitalization events and associated antibiotic use, and direct medical costs for fever-related hospitalization of study children were obtained from caregivers through weekly follow-up by study field workers. RESULTS: The incidence of hospitalization was 33 per 1000 child-years of observation. Children aged 0.5-5 years had the highest incidence of hospitalization. The top 5 infectious causes for hospitalization were acute undifferentiated fevers, respiratory tract infections, acute gastroenteritis, enteric fever, and dengue. The overall median cost of hospitalization for fever was 4243 (interquartile range, 2502-7215) Indian rupees (INR). An episode of dengue had a median cost of 5627 INR, followed by acute undifferentiated fevers and enteric fever with median costs of 3860 and 3507 INR, respectively. CONCLUSIONS: Hospitalization for fever is common in young children and impacts household finances in low-income Indian households.

OBJECTIVE: Early childhood factors can have persisting effects on development and cognition in children. We propose to explore the trends of Fe deficiency and Pb toxicity in early childhood and their association with child development at 2 years of age and cognition at 5 years. DESIGN: Longitudinal birth cohort study. SETTING: Urban slum, Vellore, India. PARTICIPANTS: Children enrolled at birth were followed up regularly in the first 2 years with developmental and cognitive assessments at 2 and 5 years of age, respectively. RESULTS: The birth cohort enrolled 251 children with 228 children followed up at 2 years and 212 at 5 years of age. Fe deficiency (ID) was highest at 15 months of age and improved subsequently at 24 months. Blood Pb levels (BLL) remained high at all age groups with an increasing trend with age; 97 % at 36 months having high BLL. Persistent high mean BLL at 15 and 24 months had negative association with both cognition and expressive language raw scores of 24 months, while high mean BLL at 15, 24 and 36 months had no significant association with any of the domains of cognition at 5 years of age. Early childhood cumulative body Fe status at 7, 15 and 24 months did not show any association with child development at 2 years, but was associated with verbal, performance and processing speed components of cognition at 5 years. CONCLUSIONS: Optimising body Fe status and limiting Pb exposure in early childhood can augment child development and school entry cognition.

We investigated an outbreak of hepatitis A infection among children in an urban settlement of Vellore, South India. A total of 58 cases of jaundice were reported between April and August 2019. Sera from children who presented with jaundice were tested for hepatitis A virus (HAV) IgM. HAV IgM was positive in 18 (94.7%) of the 19 cases tested. These children also received a blood culture at the same time, as a part of the ongoing Surveillance for Enteric Fever in India (SEFI). Blood cultures from three children with confirmed hepatitis A infection grew Salmonella sp.: two with Salmonella Typhi and one with Salmonella Poona. Salmonella Poona is being reported for the first time from India. The overall hospitalization rate during the outbreak was 21%. Outbreaks of hepatitis A continue to occur with substantial morbidity in children from endemic settings, with notable emergence of other concurrent enteric infections, thereby warranting continued surveillance.

A 5-year-old male child with blood culture confirmed typhoid fever presented with twitching over the left scapular region. Contrast computerized tomography and electroencephalogram were normal. Following treatment with azithromycin and clonazepam, the twitching subsided. Subsultus tendinum, a rare neurological complication of typhoid fever, resolves spontaneously with treatment.
