ABSTRACT
India became one of the most COVID-19 affected countries with more than 4 million infected cases and 71,000 deaths by September 2020. We studied the temporal dynamics and geographic distribution of SARS-CoV-2 subtypes in India. Moreover, we analysed the RGD motif and D614G mutation in the spike protein of SARS-CoV-2. We used a previously proposed viral subtyping method based upon informative subtype markers (ISMs). The ISMs were identified on the basis of information entropy using 94,515 genome sequences of SARS-CoV-2 available publicly at the Global Initiative on Sharing All Influenza Data (GISAID). We identified 11 distinct positions in the SARS-CoV-2 genomes for defining ISMs resulting in 798 unique ISMs. The most abundant ISM in India was transferred from European countries. In contrast, the second most abundant ISM in India was found to be transferred via Australia. Moreover, the eastern regions in India were infected by the ISM most abundant in China due to geographical linkage. Our analysis confirmed higher rates of new cases in the countries abundant with S-G614 strain compared to countries with abundant S-D614 strain. In India, overall S-G614 was most prevalent compared to S-D614, except a few regions including New Delhi, Bihar, and Rajasthan.

In response to the COVID-19 pandemic, quality improvement teams at Cleveland Clinic initiated a number of measures to guide the care of patients with suspected or confirmed COVID-19 infection and protect care givers. This included increasing the frequency of team meetings from monthly to daily or weekly and creating task forces to create protocols for patient transport, airway management, and management of personal protective equipment and medications in short supply. Enterprise wide, we postponed non-essential surgeries, set up an overflow intensive care unit onsite, created a web-based COVID-19 toolkit for all care givers, and sent daily emails about the most recent developments, decisions, and recommendations from national and international societies.
ABSTRACT
The operating room environment is very dynamic with many unique challenges for anesthesia teams caring for patients with confirmed or suspected COVID-19. Specific recommendations by national organizations and institution specific step-by-step guidelines and education materials are required to maintain safety for both patients and caregivers perioperatively, with transport, and medication management.
