“…Given that household exposures to SARS‐CoV‐2 pose a higher risk for viral transmission than nonhousehold exposures, 1,2 it is unsurprising that the SAR among participants within this study was greater than that previously reported among TTS participants following nonhousehold exposures in universally masked settings (28% vs 1.7%, respectively) 5 . The greater observed SAR in this study could also reflect the transmission dynamics and increased transmissibility of the omicron variant as compared to the delta variant; omicron was the predominant strain during this study 5 .…”

“…Since the onset of the coronavirus disease 2019 (COVID‐19) pandemic, school exclusion following exposure to severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has resulted in millions of missed school days for students and staff across the United States. Given the logistical difficulties of isolating from those within a shared household setting 1 and the high risk of viral transmission between household members, 2 current US Centers for Disease Control and Prevention (CDC) guidance recommends a longer quarantine following a household SARS‐CoV‐2 exposure, 3 resulting in an increased length of school exclusion in comparison to those who have had a non‐household SARS‐CoV‐2 exposure. Consequently, those living in crowded, shared, or multigenerational households are disproportionately impacted by prolonged school exclusion following household SARS‐CoV‐2 exposures 4 .…”

BACKGROUND Test‐to‐stay (TTS) is a strategy to limit school exclusion following an exposure to severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). We evaluated the use of TTS within universally masked kindergarten through 12th grade (K‐12) school settings following household SARS‐CoV‐2 exposure. METHODS Three hundred twenty‐two participants were enrolled. Serial rapid antigen testing was performed up to 15 days post‐exposure. Analysis‐eligible participants completed the 15‐day testing protocol, tested positive any time during the testing window, or received a negative test on or after day 9. Primary outcomes included within‐school tertiary attack rate (TAR) (test positivity among close contacts of positive TTS participants), and school days saved among TTS participants. RESULTS Seventy‐three of 265 analysis‐eligible participants tested positive for SARS‐CoV‐2 (secondary attack rate of 28% [95% CI: 16‐63%]). Among 77 within‐school close contacts, 2 were positive (TAR = 3% [95% CI: 1‐5%]). Participant absences were limited to 338 days, resulting in 82% of 1849 school days saved. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY TTS facilitates continued in‐person learning and can greatly reduce the number of missed school days. CONCLUSIONS Within universally masked K‐12 schools, TTS is a safe alternative to school exclusion following household SARS‐CoV‐2 exposure.

“…Our findings illustrate the wider impact of cases in children, with an increase in household clusters observed in both primary and secondary school-aged index cases. While we cannot determine definitively that subsequent cases within the household represent transmission from index cases, the risk from cohabitation makes this likely [ 14 - 17 ]. The rise in clusters seeded by secondary school-aged children may reflect in part the systematic asymptomatic testing of this age group at the start of the school term, leading to increased testing among household contacts.…”

Easing of COVID-19 restrictions in England in the summer of 2021 was followed by a sharp rise in cases among school-aged children. Weekly rates of SARS-CoV-2 infection in primary and secondary school children reached 733.3 and 1,664.7/100,000 population, respectively, by week 39 2021. A surge in household clusters with school-aged index cases was noted at the start of the school term, with secondary cases predominantly in children aged 5–15 years and adults aged 30–49 years.

Background: The coronavirus disease 2019 (COVID-19), caused by a virus named SARS-CoV-2, has spread rapidly around the world. Objective: To better understand the recent development of therapeutic strategies against COVID-19 and the patent landscape, we analyze patent documents surrounding COVID-19. Methods: The patent documents surrounding COVID-19 from 6 major countries, including China, the US, Russia, Korea, India, and Singapore, were analyzed by a comprehensive analysis. The patent documents surrounding COVID-19 were published from November 2019 to April 2021. Results: The analysis showed that China was the most prolific country in patents surrounding COVID-19, with over 300 published patent documents. A significant feature of therapeutic strategies against COVID-19 was the contribution of traditional Chinese medicines in China. Our study showed the number of patents in the therapeutic area was about half in all patent applications, which indicated that therapeutic approaches, detecting, and protecting approaches were the same in importance against COVID-19. Conclusion: The main therapeutic strategies against COVID-19 include traditional Chinese medicines, chemical drugs, and vaccines. An effective and fast approach against COVID-19 is to use vaccines or traditional Chinese Medicines. The present study showed the development of a therapeutic strategy surrounding COVID-19 based on patent insight for the first time and provided new insight into therapeutic strategy against COVID-19.
