Understanding the relationship between social risk factors and COVID-19 contacts.
The purpose of this study was to facilitate researchers’ understanding of the prevalence of patients' social risk factors during the pandemic and recognize how social risks may intensify COVID-19. Between January and September 2020, the researchers conducted a national survey of Kaiser Permanente members and analyzed only the data from those who responded to a set of COVID-19 survey items. The survey included questions on their experiences with social risks, whether they knew of people with COVID-19, if COVID-19 affected their emotional and mental health, and their preferred type of assistance. The study found that 62% of respondents reported social risks, with 38% reporting having 2 or more social risks. The most common response was financial strain (45%). One third of respondents reported one or more contact types with COVID-19. respondents with 2 or more COVID-19 contact types reported higher rates of housing instability, financial strain, food insecurity, and social isolation than those with fewer contacts. Fifty percent of respondents reported that COVID-19 affected their emotional, mental health negatively, and 19% of respondents noted that it affected their ability to maintain a job.

Major update 2: antibody response and risk for reinfection after SARS-CoV-2 infection-final update of a living, rapid review.
This paper is a final updated living rapid review to synthesize evidence on the SARS-CoV-2 antibody response and reinfection risk with a focus on gaps identified in the author’s prior reports. A literature review was done for English-language cohort studies evaluating IgG antibody duration at least 12 months after SARS-CoV-2 infection, the antibody response among immunocompromised adults, predictors of nonseroconversion, and reinfection risk. Study data was extracted and two investigators rated quality. Most adults had IgG antibodies after SARS-CoV-2 infection at time points greater than 12 months. Although most immunocompromised adults develop antibodies, the overall proportion with antibodies is lower compared with immunocompetent adults. Prior infection provided substantial, sustained protection against symptomatic reinfection with the Delta variant (high strength of evidence) and reduced the risk for severe disease due to Omicron variant (moderate strength of evidence). Prior infection was less protective against reinfection with Omicron overall (moderate strength of evidence), but protection from earlier variants waned rapidly (low strength of evidence).
