Clinical Presentation of Cases with SARS-CoV-2 Reinfection/ Reactivation.

BACKGROUND: Reinfection/reactivation of SARS-CoV-2 has been a matter of great interest from the immunological and vaccine perspective. However, little is known about the clinical presentation of such reinfection/reactivation. We report a case series of 9 COVID-19 patients having experienced two clinically- and/or virologically-confirmed episodes of COVID-19. METHODS: Epidemiological and clinical characteristics of 9 healthcare workers (HCWs) with two episodes of SARS-CoV-2 are described. RESULTS: The incidence of reinfection/reactivation amongst the HCWs was 2% (9 out of 491) with an average remission period of 66 days (range 43-78 days). Amongst the cases of reinfection 4/9 were asymptomatic in first episode were symptomatic in second episode. There is negative correlation between numbers of days the patients took to become SARS-CoV-2 negative by RT-CPR and/or clinically recover in the first episode and the second episode irrespective for the time spent in remission. CONCLUSION: Shorter durations of SARS-COV-2 infection in the first episode are associated with longer time to recovery in the second episode in patients with re-infection/reactivation.

Co-infection of malaria and early clearance of SARS-CoV-2 in healthcare workers.

Healthcare workers (HCWs) are at higher risk of contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Information regarding co-infection of SARS-CoV-2 with vector-borne diseases (malaria and dengue) is crucial especially for the countries wherein malaria and dengue are endemic. The objective was to study the prevalence, demographic, clinical presentations among HCWs with coronavirus disease 2019 (COVID-19) and to compare the viral clearance in HCWs with COVID-19 and co-infection of malaria and dengue. This retrospective study was conducted at a dedicated COVID-19 hospital, BYL Nair Charitable Hospital (NH), Mumbai, India April 6th-October 31st 2020. The SARS-CoV-2 infection in HCWs was confirmed by reverse transcription-plymerase chain reaction. Out of 491 HCWs infected with SARS-CoV-2, analysis of viral clearance was carried out in 467 HCWs over seven month periods, The prevalence of SARS-CoV-2 infection in HCWs was 13% (491 out of 3711). Out of the HCWs with COVID-19, prevalence of SARS-CoV-2 infection was higher among security guards (25%) with 1% mortality. The co-infection of malaria or dengue was reported in 31 HCWs (6.3%). The mean duration of virus clearance was longer (12 days) in symptomatic HCWs as compared to asymptomatic (8 days, p < .005). The recovery of SARS-CoV-2 infection in HCWs was faster (mean 8 days) with co-infection of malaria than without malaria (p < .005). We recommend universal testing of HCWs, to optimize staffing levels during the current pandemic as HCWs are the most precious resource. There is a need to effectively implement standard protocols for prevention of vector-borne diseases, especially in the hospital settings.

Prevalence and Clinical Presentation of COVID-19 among Healthcare Workers at a Dedicated Hospital in India

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is rapidly spreading in India and across the world. Healthcare workers (HCWs) are at increased risk of contracting COVID-19 due to direct or indirect exposure to COVID-19 patients, and require special attention. Limited information is available about its effect in HCWs. Secondary transmission from HCWs is a possibility among patients, family members, and the community. Therefore, it is important to investigate the infection risk of HCWs and the clinical characteristics of affected cases and possible source of infection with exposure details. Methods: The aim of this study is to analyze the medical records of HCWs with COVID-19 retrospectively and carry out the analysis of the data of HCWs with COVID-19 at TNMC and BYL Nair Charitable Hospital (NH, COVID-19 Hospital) in Mumbai. Results: Interim analysis was carried out for the data collected from 6th April to 20th August 2020. Total 3711 HCWs (frontline, 74.32%, non-frontline, 25.68%) are working at NH Mumbai. We observed 11% prevalence of SARS-CoV-2 infection among HCWs, 4% co-infection and 1% mortality. Majority (85%) of the HCWs with COVID-19 were symptomatic and 15% were asymptomatic. Comorbidities were reported in 19% of HCWs with COVID-19. Hypertension and Diabetes Mellitus were the most common co-morbidities reported. More than 4% percent of HCWs with COVID-19 were also positive for plasmodium vivax Malaria. Conclusion: The results of the study will be useful for determining the impact of COVID-19 and adverse outcomes in HCWs, identifying probable mode of acquiring SARS-CoV-2 infection in HCWs. This is required for planning the strategies to handle the epidemic of COVID-19 among HCWs in Mumbai region, and at Maharashtra state level.

Preparedness, administrative challenges for establishing obstetric services, and experience of delivering over 400 women at a tertiary care COVID-19 hospital in India.

OBJECTIVE: To provide a descriptive account of the challenges and administrative preparedness for establishing and sustaining safe obstetric services during the COVID-19 pandemic at Topiwala National Medical College & BYL Nair Charitable Hospital (NH), Mumbai, India. METHODS: The management of pregnant women with COVID-19 was implemented as per international (WHO, RCOG, ACOG) and national (Indian Council of Medical Research) recommendations and guidelines at an academic, tertiary care, COVID-19 hospital in India. RESULTS: Using a multidisciplinary approach and active engagement of a multispecialty team, obstetric services were provided to over 400 women with laboratory-confirmed COVID-19. A sustainable model is established for providing services to pregnant women with COVID-19 in Mumbai Metropolitan Region, India. CONCLUSION: With limited resources, it is possible to set up dedicated maternity services, aligned to international guidelines, for safe pregnancy outcomes in COVID-19 settings. This COVID-19 hospital addressed the challenges and implemented several known and novel methods to establish and sustain obstetric services for women with COVID-19. The model established in the present study can be replicated in other low- and middle-income countries.
