Case report on fatal human rabies infection in central India

Rabies is a zoonotic disease that affects the central nervous system of mammals and has a high mortality rate. It is a viral disease that can be prevented by vaccination. Dogs are the leading cause of human rabies deaths, accounting for up to 99% of all human rabies transmissions. On 15th December 2019 an 8 years old male child was bitten by a stray dog outside of his house. The patient visited with his parents to a nearby primary health care center on same day where his wound was washed with water. He received first dose of anti-rabies vaccine and was referred to a tertiary care center for immunoglobulin because of a history of wound bleeding. They did not visit tertiary care center for immunoglobulin as advised. 15 days after exposure on 1st January 2021 the patient presented with unusual behavior like fear of water and tremor. On examination his pupils were found dilated and he was referred to isolation ward of tertiary care center. Based on the history of animal bites and clinical signs, the patient was diagnosed as probable case of rabies. The patient eventually died within 24 hours of admission. Such kind of incident shows that there is lack of awareness regarding rabies in community. In this case, if the patient had completed the anti-rabies vaccination schedule and visited a higher centre on time for immunoglobulin, death could have been avoided. Mortality due to rabies can be prevented by raising public awareness about immunization.

Consciousness Detection on Injured Simulated Patients Using Manual and Automatic Classification via Visible and Infrared Imaging

In a disaster scene, triage is a key principle for effectively rescuing injured people according to severity level. One main parameter of the used triage algorithm is the patient’s consciousness. Unmanned aerial vehicles (UAV) have been investigated toward (semi-)automatic triage. In addition to vital parameters, such as heart and respiratory rate, UAVs should detect victims’ mobility and consciousness from the video data. This paper presents an algorithm combining deep learning with image processing techniques to detect human bodies for further (un)consciousness classification. The algorithm was tested in a 20-subject group in an outside environment with static (RGB and thermal) cameras where participants performed different limb movements in different body positions and angles between the cameras and the bodies’ longitudinal axis. The results verified that the algorithm performed better in RGB. For the most probable case of 0 degrees, RGB data obtained the following results: Mathews correlation coefficient (MMC) of 0.943, F1-score of 0.951, and precision-recall area under curve AUC (PRC) score of 0.968. For the thermal data, the MMC was 0.913, F1-score averaged 0.923, and AUC (PRC) was 0.960. Overall, the algorithm may be promising along with others for a complete contactless triage assessment in disaster events during day and night.

Clinical case of SARS-CoV-2-associated multisystem inflammatory syndrome

The clinical course, features of diagnostic examinations and difficulties in verification of the new nosology of multisystem inflammatory syndrome associated with SARS-CoV-2 in 15-year-old girls are described. The girl was taken to the Kyiv Regional Children's Hospital No. 2 with complaints of fever, intoxication syndrome, general weakness, dizziness, vertigo, lack of urine during the day. The child was examined by a consilium of doctors, examined in the laboratory and instrumentally, after a carefully collected epidemiological history revealed possible contact with a patient with coronavirus infection at the place of study and identified a probable case of multisystem inflammatory syndrome associated with SARS-CoV-2. According to the results of our own observations during the pandemic, this nosology was found in patients who relapsed into coronavirus infection in clinical or subclinical form and for the period of hospitalization had a clinical symptom complex of Kawasaki with similar symptoms. This disease is new today, has a variety of clinical manifestations and pathological features that are a problem for clinicians. After all, at present there are no unified protocols for the diagnosis and treatment of MIS-C (multisystem inflammatory syndrome) and each doctor relies on their own experience and previously described cases. This case of multisystem inflammatory syndrome will help practicing clinicians in the early stages to diagnose the disease and provide qualified care to patients. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local ethics committee of all participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the author.

Comparison of clinical, laboratory and radiological features in confirmed and unconfirmed COVID-19 patients

Background: We aimed to compare the clinical, laboratory and radiological findings of confirmed COVID-19 and unconfirmed patients. Methods: This was a single-center, retrospective study. Results: Overall, 620 patients (338 confirmed COVID-19 and 282 unconfirmed) were included. Confirmed COVID‐19 patients had higher percentages of close contact with a confirmed or probable case. In univariate analysis, the presence of myalgia and dyspnea, decreased leukocyte, neutrophil and platelet counts were best predictors for SARS-CoV-2 RT-PCR positivity. Multivariate analyses revealed that only platelet count was an independent predictor for SARS-CoV-2 RT-PCR positivity. Conclusion: Routine complete blood count may be helpful for distinguishing COVID-19 from other respiratory illnesses at an early stage, while PCR testing is unique for the diagnosis of COVID-19.

Preparedness, Identification and Care of COVID-19 Cases by Front Line Health Workers in Selected Health Facilities in Mbale District Uganda: A Cross-Sectional Study

Introduction: The nature of work of Health care professionals exposes them to high risks of contracting COVID-19 and spreading it among themselves, to their patients and subsequently to the general community. Thus, it is essential that frontline health workers are equipped with both material and knowledge to enable them accurately suspect, detect, isolate, and manage COVID-19 cases. Findings have indicated a high prevalence of COVID-19 infections among front-line health workers. The Current Study assessed preparedness, identification, and care of COVID-19 Cases by frontline health workers in selected health facilities in Mbale District. Methodology: Across sectional survey was used to collect quantitative data using Google forms, An online platform for data collection. Data was collected from 189 frontline health workers in both government and private Health facilities in Mbale District between April and August 2020. Data was analysed using Statistical Package for the Social Sciences (SPSS) version 20. Findings: The study found that a good proportion of frontline health workers can identify cases by symptom and case definitions as probable case 113/189(59.8%), suspected case 60/189(36%) and confirmed case 22/189 (11.6%). There were generally low levels of preparedness in terms of initial service care being offered with the highest being 53/189(28.2%) and 50/189(26.4%) for facilities that had places for isolation and those with intravenous fluids respectively and the least was being able to offer oxygen and Intensive Care Services at 43/189(22.0%) and 20/189(10.3%) respectively. Conclusion and recommendations: There’s a need to ensure a continuous supply of PPEs and IPC materials to health facilities. CPD programs are essential in equipping Health workers with up-to-date information on COVID-19 Case Management. Facilities should be supported to setup isolation facilities at all levels, both permanent and temporary. Provision of Face masks to health workers should be prioritised and hand washing facilities should be installed at every serving point.

376. Sensitivity and Specificity of the WHO Probable SARS-CoV-2 Case Definition Among Symptomatic Healthcare Personnel

Background SARS-CoV-2 continues to spread globally, including in limited resource settings. It is therefore important to derive general case definitions that can be useful and accurate in the absence of timely test results. We aim to validate the World Health Organization (WHO) case definition, a symptom-screening tool currently used to identify SARS-CoV-2 cases in a cohort of symptomatic health care providers (HCP) who completed a symptom survey interview and received a PCR test at Boston Medical Center (BMC) between March 13, 2020 and May 5, 2020. Methods We classified each HCP as a probable or not probable case of SARS-CoV-2 based on the WHO case definition. Using PCR test as gold standard, we computed the sensitivity and specificity of the WHO case definition. We used a stepwise logistic regression model on all PCR-tested HCP to identify symptoms predictive of PCR positivity. Results Of 328 included HCP, 109 (33.2%) were PCR positive, 213 (64.9%) negative, and 6 (1.8%) had indeterminate test result. The sensitivity and specificity of the WHO case definition were 65.1% and 74.6%, respectively. The positive predictive value was 56.8% and the negative predictive value was 80.7%. Symptoms found to be predictive of PCR positivity were fever, headache, loss of smell and/or loss of taste, and muscle ache/joint pain. Sore throat was found to be predictive of PCR negativity. The area under the curve using the final model was 0.8412. All statistically significant symptoms included in the final model, were also included in the WHO case definition. Conclusion In our largely symptomatic HCP cohort, our model yielded similar symptoms to those identified in the WHO probable case definition. As seen in similar studies, it is unlikely that further adjustment will improve the performance of a SARS-CoV-2 case definition. However, it is concerning that 35% (38/109) of PCR positive SARS-CoV-2 HCP would have been classified as not probable cases by the WHO definition, given that this definition does not even include asymptomatic cases. This is further evidence for global building of laboratory capacity and development of affordable diagnostics to improve global pandemic control. Disclosures All Authors: No reported disclosures

1147. Sentinel Surveillance of Bacterial Pneumonia in Children Under 5 years Treated in HOMI - Fundación Hospital pediatrico la Misericordia in Bogotá, Colombia 2016-2020

Background Pneumonia is one of the leading causes of hospitalization and death in children under 5y. The main causes of bacterial pneumonia (BP) are Streptococcus pneumoniae (Spn) and Haemophilus influenzae (Hi). Colombia implemented the Hib vaccine in 1997 with a 3 + 0 scheme and the PCV10 vaccine in 2012, using a 2 + 1 scheme. Sentinel surveillance of BP is carried out at HOMI - Fundación Hospital Pediátrico La Misericordia, which is part of the invasive bacterial vaccine preventable disease surveillance network. Methods A daily active search for cases that met the definitions established in the protocol of the Pan American Health Organization was carried out. All hospitalized patients under 5 years of age with a diagnosis of community acquired pneumonia (ICD10 J10 to J22) were classified as suspected cases, while all suspected cases in which chest X-ray showed a radiological pattern compatible with bacterial pneumonia were considered a probable case. Blood cultures were taken from probable cases; if results were positive (Spn, Hi), the samples were sent to the district and national reference laboratories for confirmation and serotyping. The data obtained in the period January 2016 to December 2020 were analyzed. Results 5272 suspected cases of bacterial pneumonia were found, of which 60% were < 2 y. The highest incidence occurred from March to June (Figure 1). Blood cultures were performed in 2223 (92%) of the 2432 (46.1%) probable cases, confirming 127 (5.2%) cases. Spn, Hi, and other bacteria were found in 55, 27, and 28 cases, respectively (Table 1). Serotyping was performed in 85.4% of the Spn isolates and 77.7% of Hi isolates. The most frequent Spn serotypes were Spn19A in 19 cases (40.4%), Spn3 in 12 cases (25.5%), and Spn14 in 4 cases (8.5%). The presence of Spn19A has increased over time (Figure 2). The most frequent Hi was non-typeable in 13 patients (61.9%), followed by serotype b 6 (28.5%) and serotype a 2 (9.5%). The rate of hospitalization for BP was 9/1000 children < 5 years, and 43 patients died. Case fatality rate was 1.7% among probable cases. Graph 1. Trend of suspected bacterial pneumonia cases in children under 5 years old. HOMI. 2016-2020 Table 1. Bacterial pneumonia isolates. HOMI. 2016 - 2020 Graph 2. Bacterial pneumonia serotypes. HOMI. January 2016 - December 2020 Conclusion BP mainly occurs in 2-year-old children. Spn 19A is the most common bacteria. Although the most frequent Hi is non-typeable, cases of Hib are still observed. Sentinel surveillance allows measuring the impact of public health interventions on this disease.

Fatal Rift Valley Fever Outbreak Caused By Exposure To Meat From Sick And Dead Livestock: Uganda, July 2018

Background: Rift Valley Fever (RVF) is a viral hemorrhagic fever that can be fatal to humans and livestock. During June-October 2018, reported RVF cases increased sharply in eight western and central Ugandan districts. We investigated to identify the scope of the outbreak, determine risk factors, and recommend control measures.Methods: We defined a probable case as acute onset of unexplained fever with thrombocytopenia or leukopenia, plus ≥1 of: unexplained bleeding, blurred vision, or unexplained death during June–October 2018 in a resident of the affected districts. A confirmed case was a probable case with a positive PCR test for RVF. We reviewed medical records and actively searched for cases in communities. In a case-control study, we compared exposures of cases and age-, sex-, and neighbourhood-matched controls. We reviewed livestock RVF surveillance data.Results: We identified 19 cases (17 confirmed, 2 probable); 13 (68%) died. The mean age of the case-patients was 36 (range: 27-55) years. The attack rate in men (15/10,000) was 19 times higher than in women (0.78/10,000). Stratified epidemic curves indicated multiple point-source outbreaks, often following skinning/butchering livestock or eating grilled meat from livestock that had been sick or died of unknown causes (‘sick/dead livestock’). All case-patients with data (n=18) ate or butchered meat from sick/dead livestock. Of the 18 case-patients and 90 controls who participated in the case-control study, 10 case-patients (56%) and five controls (5.6%) cut or handled raw meat from sick/dead livestock (ORadj=14, 95%CI=2.8-72). RVF-seropositive livestock were identified from serum samples taken from farms where human cases had occurred.Conclusion. Human RVF outbreaks in Western and Central Uganda in 2018 were caused by contact with raw meat of sick/dead livestock. We recommended wearing protective gear during butchering, and safe handling and disposal of carcasses of sick/dead livestock. RVF surveillance data between human and livestock health sectors should be shared to facilitate early warning and detection for RVF.

A probable case of collapse due to hyoscine patch

This case report highlights the potentially serious side effects of hyoscine and how a seemingly innocuous patch may confound patients and doctors alike. It demonstrates how easy it is to miss an obvious diagnosis when in fact a thorough medical history including an exhaustive drug history can easily point us in the direction of the diagnosis fairly quickly. Finally, hyoscine may cause potentially serious side effects and patients who are taking it, either orally or transdermally, should be made aware of these.
