ABSTRACT
Background: The purpose of this work was to describe the experiences of EMS personnel in responding to drug overdose-related calls and the impact the pandemic has had to help better inform current response and treatment efforts. Methods: Semi-structured interviews were conducted with 99 EMS personnel across 18 areas throughout the United States that were designated as Early Warning Network sentinel sites by the National Institute on Drug Abuse-funded National Drug Early Warning System. Participants were asked about topics including the potential burdens from the pandemic and the opioid crisis. We coded the interview responses and identified themes through qualitative analysis. Multiple cycles of descriptive coding, recoding, subcoding, pattern-coding, and thematic coding of responses were conducted. Results: Responses were categorized into the following themes: 1) being over-worked from increased call volume;2) increased risk for personal harm when responding to patients;3) compassion fatigue due to long hours and repeat calls for the same people;4) conflicting perceptions of the utility of naloxone;5) the need for better treatment options to respond to opioid crisis on top of COVID-19. Conclusions: The burden of the substance use disorder (SUD) crisis on EMS personnel has been compounded by the COVID-19 pandemic. These reports from EMS personnel throughout the US can help inform policy and procedures to better protect the mental health of EMS personnel and to ensure better care for patients with SUD. These experiences and recommendations may be of use for other countries as substance use and COVID-19 are global health issues. © 2023 The Authors.

ABSTRACT
Background. The consequences of SARS-CoV2 reinfections for patients, healthcare workers and society are unclear. We reviewed the clinical, laboratory, and epidemiological characteristics of patients re-infected with genetically distinct strains of SARS-CoV2 identified by Whole Virus Genome Sequencing (WvGS). Methods. Cases were selected based on a positive SARS-CoV-2 Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) test, clinical resolution, a negative interim test and a subsequent positive nasopharyngeal swab. Positive samples were prepared for sequencing by cDNA synthesis, tiled-PCR following the ARTIC protocol and amplicon sequencing using Illumina MiSeq platform. Raw reads were mapped to the reference sequence using bowtie and Samtools was used for variants calling and to generate the consensus sequences. Comparative sequence analysis was conducted by phylogenetic inference maximum likelihood method with RAxML using the multiple sequence aligned by MAFFT. Clades and variants were assigned respectively using Nextstrain and Pangolin COVID-19 lineage assigner (Figure 1). The clinical, radiological and laboratory data were collected from patient medical notes and laboratory information system. Results. Two cases of SARS-CoV-2 reinfection were detected by RT-PCR (patient 1 and 2). CT values and strain variants are presented in Table 1. The time between detection of the first and second infection was 67 and 270 days respectively. WvGS confirmed that the second episodes were due to a genetically distinct strain of SARS CoV2. These reflected the dominant contemporaneous variants in circulation. Both patients were immunocompromised from co-morbidities and medications. First and subsequent infections were minimally symptomatic. Both cases were associated with known hospital outbreaks. They passed away within 2 weeks of the second infection of unrelated causes. Conclusion. Two patients in this study were diagnosed with a SARS-CoV-2 reinfection confirmed by WvGS. A common factor in these cases was immunocompromise. Where a previously infected patient test shows a new positive or an unexpected reduction in CT value is observed, we recommend individual risk assessment to determine the timing of discontinuation of isolation and infection control precautions.
