Public Health Interventions for the COVID-19 Pandemic Reduce Respiratory Tract Infection-Related Visits at Pediatric Emergency Departments in Taiwan.
Background and objective: Public health interventions such as social distancing, wearing surgical or N95 masks, and handwashing are effective in significantly reducing the risk of infection. The purpose of this article is to analyze the effect of public health interventions on respiratory tract infection-related visits to pediatric emergency departments during the COVID-19 pandemic in Taiwan. Method: Pediatric emergency department visits between January 1 2020 and April 30 2020 were included for trend analysis and compared to the same period during the past 3 years. ⋯ On the other hand, the proportion of urinary tract infections was significantly higher in 2020 during March (3.7 vs. 5.2%, p = 0.033) and April (3.9 vs. 6.5%, p < 0.001), and that of asthma was also higher in April (1.6 vs. 2.6%, p = 0.025). Furthermore, the intensive care unit admission rate was relatively higher in 2020 from February, with significant differences noted in March (1.3 vs. 2.8%, p < 0.001). Conclusion: Due to public health interventions for the COVID-19 pandemic, the transmission of not only COVID-19 but also other air droplet transmitted diseases in children may have been effectively prevented.

The SARS-CoV-2 outbreak in 2019 highlighted the fact that no specific medications providing effective treatment have been identified and approved. We explored the possibilities for COVID-19 by systematically reviewing evidence on the efficacy and safety of glycyrrhizin preparations for SARS and MERS. Electronic databases were systematically searched from inception to February 2020 for eligible studies that evaluated the efficacy and safety of glycyrrhizin preparations for SARS and MERS. ⋯ Compared to that with conventional medications, the average period from peak to 50% improvement of lesions, in terms of X-ray manifestations, was shorter with compound glycyrrhizin treatment ([Formula: see text]2.1[Formula: see text]d), and treatment reduced the dosage ([Formula: see text][Formula: see text]mg/d) and duration of the corticosteroids used, without other serious adverse reactions. Based on the available evidence regarding glycyrrhizin preparations for treating SARS and MERS, we infer that compound glycyrrhizin could be an optional therapeutic strategy for SARS-CoV-2 infections, especially those complicated with liver damage. Further research using well-designed randomized clinical trials (RCTs) is warranted to determine the dosage and duration of use of compound glycyrrhizin and to monitor its specific adverse effects.

Immunoinformatic Analysis of SARS-CoV-2 Nucleocapsid Protein and Identification of COVID-19 Vaccine Targets.
COVID-19 is a worldwide emergency; therefore, there is a critical need for foundational knowledge about B and T cell responses to SARS-CoV-2 essential for vaccine development. However, little information is available defining which determinants of SARS-CoV-2 other than the spike glycoprotein are recognized by the host immune system. In this study, we focus on the SARS-CoV-2 nucleocapsid protein as a suitable candidate target for vaccine formulations. ⋯ Most notably there is a region of potential T cell cross-reactivity within the SARS-CoV-2 N protein position 102-110 amino acids that traverses multiple human alpha and betacoronaviruses. Vaccination strategies designed to target these conserved epitope regions could generate immune responses that are cross-reactive across human coronaviruses, with potential to protect or modulate disease. Finally, these predictions can facilitate effective vaccine design against this high priority virus.

COVID-19 in long-term care facilities in Frankfurt am Main, Germany: incidence, case reports, and lessons learned.
As of August 30, 2020, the World Health Organisation (WHO) reported 24,822,800 COVID-19 infections world wide. Severe disease and deaths occur especially in older people with chronic illnesses. Residents of nursing homes are considered to be the most vulnerable group. ⋯ Due to the measures taken (monitoring of residents and staff, nursing care in protective clothing, prohibition or restriction of visits, physical distancing, isolation of infected people and quarantining of contact persons), only individual cases of COVID-19 illnesses occurred in nursing home residents in most homes and the outbreaks in the three homes could be stopped. We do not recommend regular nontargeted testing in nursing homes, but rather vigilance and the implementation of good hygiene as well as immediate targeted testing if COVID-19 is suspected in residents or staff. In order to mitigate the considerable negative effects of these measures on the residents, a good balance should be sought between infection prevention and the goal of ensuring self-determination and the residents' quality of life.
