CORONAVIRUS INFO PROVIDED BY DR. JIM HARRIS – 9/24/2020

September 24, 2020

Yesterday, Harrison County reported 8 new cases, Gregg 7, and Smith County 22. 

From Johns Hopkins:

1. WEDDING RECEPTION OUTBREAK An August wedding in Maine has been linked to more than 175 associated cases and 8 deaths, including many who did not attend the wedding. Notably, none of the associated deaths attended the wedding. Six of the 8 deaths were residents of a nearby long-term care facility, where an employee who lives with someone who attended the wedding is believed to have introduced the virus. Associated cases have been identified in multiple long-term care facilities and the county jail. The outbreak at the jail has been attributed to an employee who attended the wedding, and it has resulted in at least 84 cases, including nearly half of the incarcerated population and employees as well as 17 household contacts of employees.

The wedding reportedly had 62-65 attendees and an indoor ceremony and reception, which violated the state prohibition on gatherings of more than 50 people, and attendees reportedly did not adhere to recommendations regarding physical distancing or mask use. All attendees had their temperatures checked before entering; however, this failed to identify infectious individuals. The Maine CDC issued an “imminent health hazard” citation to the event facility where the reception was held for failing to maintain social distancing measures, allowing too many people to congregate, and neglecting to collect contact information from wedding guests. The facility reportedly suspended all operations due to the outbreak. This case study highlights the potential for transmission at individual events to spill over into the community as well as the limitations of temperature or symptom monitoring to identify infectious individuals.(J. Harris: This could happen tomorrow at any site in the US. Good tracking and testing made the situation informative — as well as frightening. The contagiousness of the virus is still as prevalent as it was in August. So, space out, avoid crowds, and wear your mask.)

2. Long-term hydroxychloroquine use in patients with rheumatic conditions and development of SARS-CoV-2 infection: a retrospective cohort study

From The Atlantic:The Core Lesson of the COVID-19 Heart Debate (The Atlantic) Autopsies have found traces of the coronavirus’s genetic material in the heart, and actual viral particles within the heart’s muscle cells. Experiments have found that SARS-CoV-2 can destroy lab-grown versions of those cells. Several studies have now shown that roughly 10 to 30 percent of hospitalized COVID-19 patients had high levels of troponin—a protein released into the blood when the heart’s muscle cells are damaged. Such patients are more likely to die than others with no signs of heart injury.

From Johns Hopkins:

1. Measurement of SARS-CoV-2 RNA in Wastewater Tracks Community Infection Dynamics(Nature Biotechnology) We measured severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA concentrations in primary sewage sludge in the New Haven, Connecticut, USA, metropolitan area during the Coronavirus Disease 2019 (COVID-19) outbreak in Spring 2020. SARS-CoV-2 RNA was detected throughout the more than 10-week study and, when adjusted for time lags, tracked the rise and fall of cases seen in SARS-CoV-2 clinical test results and local COVID-19 hospital admissions. Relative to these indicators, SARS-CoV-2 RNA concentrations in sludge were 0–2 d ahead of SARS-CoV-2 positive test results by date of specimen collection, 0–2 d ahead of the percentage of positive tests by date of specimen collection, 1–4 d ahead of local hospital admissions and 6–8 d ahead of SARS-CoV-2 positive test results by reporting date. Our data show the utility of viral RNA monitoring in municipal wastewater for SARS-CoV-2 infection surveillance at a population-wide level. In communities facing a delay between specimen collection and the reporting of test results, immediate wastewater results can provide considerable advance notice of infection dynamics.

2. EYEGLASSES Researchers from China published findings from study investigating whether the use of eyeglasses provides protection against SARS-CoV-2 transmission. The study, published in JAMA: Ophthalmology, included a cohort of 276 hospitalized COVID-19 patients in Hubei Province in January-March. Among these patients, 5.8% routinely wore eyeglasses—defined as more than 8 hours per day—compared to an estimated 31.5% among the general public. The researchers hypothesize that wearing glasses could reduce the amount that people touch their eyes, which could reduce SARS-CoV-2 transmission. While protective eyewear is recommended for healthcare professionals, peer-reviewed evidence is limited regarding any potential protective effect for the general public. Further research is necessary to better characterize any effect of eyeglasses on mitigating SARS-CoV-2 transmission risk outside the context of the healthcare setting.

3. SARS-CoV-2–Associated Deaths Among Persons Aged <21 Years — United States, February 12–July 31, 2020 Among 121 SARS-CoV-2–associated deaths among persons aged <21 years reported to CDC by July 31, 2020, 12 (10%) were infants and 85 (70%) were aged 10–20 years. Hispanic, non-Hispanic Black and non-Hispanic American Indian/Alaskan Native persons accounted for 94 (78%) of these deaths; 33% of deaths occurred outside of a hospital. Persons aged <21 years exposed to SARS-CoV-2 should be monitored for complications. Ongoing surveillance for SARS-CoV-2–associated infection, hospitalization, and death among persons aged <21 years should be continued as schools reopen in the United States. (CDC MMWR, 9/18/2020)
