Teenagers in the United States are one of the populations whose HIV infection rates are increasing most rapidly. This study was designed to measure college students' knowledge of HIV transmission methods using Kittleson and Venglarcik's HIV Transmission Survey. Participants ( N = 167) were divided into two groups, 99 students from a rural background and 68 students from an urban background. Students from an urban background were significantly more knowledgeable about documented HIV transmission modes than students from a rural background. Men were significantly less aware of documented HIV transmission modes than women. These results suggest that education about AIDS needs to be improved. The current educational procedures do not properly inform students in a fashion which exhibits the true risk of infection and those behaviors which increase risk. Fifteen years after the discovery of the HIV virus students are still largely unaware that they are at risk for contracting a fatal disease.

AbstractGreat efforts are devoted to end the HIV epidemic as it continues to have profound public health consequences in the United States and throughout the world, and new interventions and strategies are continuously needed. The use of HIV sequence data to infer transmission networks holds much promise to direct public heath interventions where they are most needed. As these new methods are being implemented, evaluating their benefits is essential. In this paper, we recognize challenges associated with such evaluation, and make the case that overcoming these challenges is key to the use of HIV sequence data in routine public health actions to disrupt HIV transmission networks.

Background: Each year, the FDA receives more than a million reports of suspected device-associated deaths, serious injuries, and malfunctions. Medical device reports (MDRs) are submitted to the FDA by mandatory reporters (manufacturers, importers, and device user facilities) and voluntary reporters such as healthcare professionals, patients, and consumers. The FDA uses MDRs to monitor device performance, including monitoring reports of infection or device contamination to detect potential device-related safety issues and to share this information in public communications. In this analysis, the FDA presents MDRs for duodenoscopes, which are a type of flexible endoscope that have been associated with infections in patients. Methods: For this analysis, we searched the MDR database for duodenoscope reports submitted between January 2015 and July 1, 2019. MDRs were classified into clinical risk categories based on the MDR’s text narratives as patient infection (indicated the presence of infection in patients potentially transmitted by the device), patient exposure (indicated a contaminated device has been used in a patient, but the MDR lacks clear mention of patient infection), or device contamination (indicated that the device was contaminated, but no mention of device use in patients or patient infection). Results: Overall, 1,115 duodenoscope reports related to a patient infection, patient exposure, or device contamination for devices marketed inside and outside the United States were received from January 2015 to mid-2019. Among them, 79 MDRs were received for deaths in patient infection, patient exposure, or device contamination reports. The number of reported infections decreased from 247 MDRs in 2015 to 55 MDRs in the first half of 2019. Furthermore, the number of reported deaths decreased from 25 MDRs in 2015 to 2 MDRs reported in the first half of 2019. Conclusions: The MDR data indicate a decrease in the number of reported infections. The decrease in infections suggests that efforts to reduce the risk of infection from duodenoscopes have yielded improvements; however, additional improvements are necessary to further decrease the risk of infection.Funding: NoneDisclosures: None

Abstract Recurrence of local transmission of Zika virus in Puerto Rico is a major public health risk to the United States, where mosquitoes Aedes aegypti (Linnaeus) and Aedes mediovittatus (Coquillett) are abundant. To determine the extent to which Ae. mediovittatus are capable of transmitting Zika virus and the influence of viremia, we evaluated infection and transmission in Ae. mediovittatus and Ae. aegypti from Puerto Rico using serial dilutions of infectious blood. Higher doses of infectious blood resulted in greater infection rates in both mosquitoes. Aedes aegypti females were up to twice as susceptible to infection than Ae. mediovittatus, indicating a more effective midgut infection barrier in the latter mosquito species. Aedes aegypti exhibited higher disseminated infection (40–95%) than Ae. mediovittatus (<5%), suggesting a substantial midgut escape barrier in Ae. mediovittatus. For Ae. aegypti, transmission rates were low over a range of doses of Zika virus ingested, suggesting substantial salivary gland barriers.

The Impact

Although vaccination is carried out worldwide, the vaccination rate varies greatly. As of 24 May 2021, in some countries, the proportion of the population fully vaccinated against COVID-19 has exceeded 50%, but in many countries, this proportion is still very low, less than 1%. This article aims to explore the impact of vaccination on the spread of the COVID-19 pandemic. As the herd immunity of almost all countries in the world has not been reached, several countries were selected as sample cases by employing the following criteria: more than 60 vaccine doses per 100 people and a population of more than one million people. In the end, a total of eight countries/regions were selected, including Israel, the UAE, Chile, the United Kingdom, the United States, Hungary, and Qatar. The results find that vaccination has a major impact on reducing infection rates in all countries. However, the infection rate after vaccination showed two trends. One is an inverted U-shaped trend, and the other is an L-shaped trend. For those countries with an inverted U-shaped trend, the infection rate begins to decline when the vaccination rate reaches 1.46–50.91 doses per 100 people.

Abstract Introduction Causes of COVID-19 burden in urban, suburban, and rural counties are unclear, as early studies provide mixed results implicating high prevalence of pre-existing health risks and chronic diseases. However, poor sleep health that has been linked to infection-based pandemics may provide additional insight for place-based burden. To address this gap, we investigated the relationship between habitual insufficient sleep (sleep <7 hrs./24 hr. period) and COVID-19 cases and deaths across urban, suburban, and rural counties in the US. Methods County-level variables were obtained from the 2014–2018 American community survey five-year estimates and the Center for Disease Control and Prevention. These included percent with insufficient sleep, percent uninsured, percent obese, and social vulnerability index. County level COVID-19 infection and death data through September 12, 2020 were obtained from USA Facts. Cumulative COVID-19 infections and deaths for urban (n=68), suburban (n=740), and rural (n=2331) counties were modeled using separate negative binomial mixed effects regression models with logarithmic link and random state-level intercepts. Zero-inflated models were considered for deaths among suburban and rural counties to account for excess zeros. Results Multivariate regression models indicated positive associations between cumulative COVID-19 infection rates and insufficient sleep in urban, suburban and rural counties. The incidence rate ratio (IRR) for urban counties was 1.03 (95% CI: 1.01 – 1.05), 1.04 (95% CI: 1.02 – 1.05) for suburban, and 1.02 (95% CI: 1.00 – 1.03) rural counties.. Similar positive associations were observed with county-level COVID-19 death rates, IRR = 1.11 (95% CI: 1.07 – 1.16) for urban counties, IRR = 1.04 (95% CI: 1.01 – 1.06) for suburban counties, and IRR = 1.03 (95% CI: 1.01 – 1.05) for rural counties. Level of urbanicity moderated the association between insufficient sleep and COVID deaths, but not for the association between insufficient sleep and COVID infection rates. Conclusion Insufficient sleep was associated with COVID-19 infection cases and mortality rates in urban, suburban and rural counties. Level of urbanicity only moderated the relationship between insufficient sleep and COVID death rates. Future studies should investigate individual-level analysis to understand the role of sleep mitigating COVID-19 infection and death rates.

The Relationship

Introduction: Infection has been described as a trigger for acute ischemic stroke, but the relationship between postoperative infection and the risk of postoperative stroke is unclear. We investigated the association between postoperative infection and stroke using the American College of Surgeons National Surgical Quality Initiative Program (NSQIP) database. Hypothesis: Postoperative infection is associated with an increased risk of postoperative stroke. Methods: We used the NSQIP database to identify all patients who underwent surgery between the years of 2000 and 2010 and developed a postoperative stroke within 30 days of surgery. The group was further stratified according to the presence of infection preceding stroke. Using a logistic regression model adjusted for age, race, sex, medical comorbidities, surgical type, and dichotomized functional status, we compared the risk of stroke in patients with and without preceding infections, and investigated the risk of infection following stroke. Results: 729,886 surgical patients were identified, of whom 2,703 (0.3%) developed postoperative stroke. 848 (0.12%) patients developed both postoperative stroke and infection. Among patients who had postoperative stroke, 100 (3.7%) had developed an infection prior to developing a stroke. Patients with infection prior to stroke had a lower risk of stroke than patients who did not develop infection prior to stroke (adjusted odds ratio [OR] 0.25, 95%CI 0.20-0.32). 748 patients (0.1%) developed an infection after having a postoperative stroke. These patients had a higher risk of infection (incidence rate ratio 2.76, 95%CI 2.57-2.97) and a higher odds of infection (adjusted odds ratio [OR] 3.47, 95%CI 3.18-3.78) than patients who did not have a stroke. Conclusions: We found that the presence of a preceding infection was associated with a low risk of postoperative stroke in a large surgical inpatient sample. Although the total number of strokes may have been under-reported, these results conflict with other studies that report that infection is a trigger for ischemic stroke. Further analyses using more granular data are needed to investigate the relationship between postoperative infection and the risk of postoperative stroke.
