ObjectivesThis study examined knowledge and perceptions of COVID-19, prevalence of pre-existing conditions and access to essential resources among residents of internally displaced person (IDP) camps in Somalia, where overcrowded settlements with weakened infrastructure, inadequate water, sanitation, and hygiene facilities, and limited access to health services make this vulnerable population particularly susceptible to a COVID-19 outbreak.DesignA descriptive, cross-sectional survey.SettingTwelve IDP camps across six areas of the Lower Shabelle region in Somalia.Participants401 adult Somali IDP camp residents.ResultsThe majority of participants were female (86%) and had received no formal education (89%). While 58% reported being in ‘good’ health, half of the participants reported having one or more pre-existing conditions. Though 77% of respondents reported taking at least one COVID-19 preventative public health measure, respondents reported a lack of access to adequate sanitation, an inability to practice social distancing and nearly universal inability to receive a COVID-19 screening exam. Questions assessing knowledge surrounding COVID-19 prevention and treatment yielded answers of ‘I don’t know’ for roughly 50% of responses. The majority of participants were not familiar with basic information about the virus or confident that they could receive medical services if infected. 185 (47%) respondents indicated that camp living conditions needed to change to prevent the spread of COVID-19.ConclusionThis study highlights low levels of COVID-19 knowledge and limited access to essential prevention and treatment resources among individuals living in Somali IDP camps. A massive influx of additional resources is required to adequately address COVID-19 in Somalia, starting with codesigning interventions to educate those individuals most vulnerable to infection.

Despite its great promise of fault tolerance, the simplest demonstration of topological quantum computation remains elusive. Majorana modes are the primitive building blocks and their experimental realization on various platforms is yet to be confirmed. This work presents an experimental and theoretical framework for the space-resolved detection and exchange of Majorana modes on programmable (noisy) quantum hardware. We have implemented our framework by performing a series of measurements on a driven Ising-type quantum spin model with tunable interactions, which confirm the existence of the topological Majorana modes and distinguishes them from trivial modes. Lastly, we propose and demonstrate a novel technique for braiding the Majorana modes which results in the correct statistics but decreases the magnitude of the signal. The present work may be seen as the first reliable observation of Majorana modes on existing quantum hardware.

Background Open online forums like Reddit provide an opportunity to quantitatively examine COVID-19 vaccine perceptions early in the vaccine timeline. We examine COVID-19 misinformation on Reddit following vaccine scientific announcements, in the initial phases of the vaccine timeline. Methods We collected all posts on Reddit (reddit.com) from January 1 2020 - December 14 2020 (n=266,840) that contained both COVID-19 and vaccine-related keywords. We used topic modeling to understand changes in word prevalence within topics after the release of vaccine trial data. Social network analysis was also conducted to determine the relationship between Reddit communities (subreddits) that shared COVID-19 vaccine posts, and the movement of posts between subreddits. Results There was an association between a Pfizer press release reporting 90% efficacy and increased discussion on vaccine misinformation. We observed an association between Johnson and Johnson temporarily halting its vaccine trials and reduced misinformation. We found that information skeptical of vaccination was first posted in a subreddit (r/Coronavirus) which favored accurate information and then reposted in subreddits associated with antivaccine beliefs and conspiracy theories (e.g. conspiracy, NoNewNormal). Conclusions Our findings can inform the development of interventions where individuals determine the accuracy of vaccine information, and communications campaigns to improve COVID-19 vaccine perceptions, early in the vaccine timeline. Such efforts can increase individual- and population-level awareness of accurate and scientifically sound information regarding vaccines and thereby improve attitudes about vaccines, especially in the early phases of vaccine roll-out. Further research is needed to understand how social media can contribute to COVID-19 vaccination services.

Background: Three million internally displaced Somalis live in overcrowded settlements with weakened infrastructure, insufficient access to WASH facilities, and inaccessible health services. This vulnerable population is especially susceptible to COVID-19, which is expected to have worsened health outcomes and exacerbate existing structural challenges in the implementation of public health measures. This study examines knowledge of COVID-19, self-reported prevalence of preexisting conditions, and access to essential health services among residents of internally displaced persons (IDP) camps in Somalia. Methods: A descriptive, cross-sectional survey design assessing demographics, current health profiles, knowledge and perceptions of COVID-19, and access to resources was used. 401 Somali IDP camp residents completed the survey. Results: Though 77% of respondents reported taking at least one COVID-19 preventative public health measure, respondents reported a severe lack of access to adequate sanitation, an inability to practice social distancing, and nearly universal inability to receive a COVID-19 screening exam. Questions assessing knowledge surrounding COVID-19 prevention and treatment yielded answers of "I don't know" for roughly 50% of responses. The majority were not familiar with basic information about the virus or confident that they could receive medical services if infected. Those who perceived their health status to be "fair," as opposed to "good," showed 5.69 times higher odds of being concerned about contracting COVID-19. Respondents who felt more anxious or nervous and those who introduced one behavioral change to protect against COVID-19 transmission showed 10.16 and 5.20 times increased odds of being concerned about disease contraction, respectively. Conclusion: This study highlights immense gaps in the knowledge and perceptions of COVID-19 and access to treatment and preventative services among individuals living in Somali IDP camps. A massive influx of additional resources is required to adequately address COVID-19 in Somalia, starting with educating those individuals most vulnerable to infection.
