9/25—Poor self-reported adherence to COVID-19-related quarantine requests, Norway
We found low self-reported adherence to requested measures among 1,704 individuals (42%; 95% confidence interval: 37–48). Adherence was lower in May–June–July (33–38%) compared with April (66%), and higher among those experiencing COVID-19-compatible symptoms (71%) compared with those without (28%) (Steens et al. 2020).
Mass Events Trigger Malta's Second Peak After Initial Successful Pandemic Suppression
Stability was disrupted when two major mass events were organized despite various health professional warnings. In a matter of few just days, daily cases rose to two-digit figures, with high community transmission, a drastic rise in active cases, and a rate per hundred thousand in Europe second only to Spain.
Association of Daily Wear of Eyeglasses With Susceptibility to Coronavirus Disease 2019 Infection
A total of 276 patients with COVID-19 were enrolled in Suizhou Zengdu Hospital, China. The proportion of people with myopia in Hubei province, based on a previous study, was 31.5%, which was much higher than the proportion of patients with COVID-19 who had myopia in this sample (5.8%; 95% CI, 3.04%-8.55%), suggesting that daily wearers of eyeglasses may be less susceptible to COVID-19.
SARS-CoV-2 Viral Load Predicts Mortality in Patients with and Without Cancer Who Are Hospitalized with COVID-19
We measured SARS-CoV-2 viral load using […] RT-PCR specimens in 100 patients with cancer and 2914 without cancer who were admitted to three New York City hospitals. Overall, the in-hospital mortality rate was 38.8% among patients with a high viral load, 24.1% among patients with a medium viral load, and 15.3% among patients with a low viral load (P<0.001). SARS-CoV-2 viral load results may offer vital prognostic information for patients who are hospitalized with COVID-19.
Occurrence and transmission potential of asymptomatic and presymptomatic SARS-CoV-2 infections: A living systematic review and meta-analysis
The overall estimate of the proportion of people who become infected with SARS-CoV-2 and remain asymptomatic throughout infection was 20% (95% confidence interval [CI] 17–25). The secondary attack rate was lower in contacts of people with asymptomatic infection than those with symptomatic infection (relative risk 0.35, 95% CI 0.10–1.27). The findings of this living systematic review suggest that most people who become infected with SARS-CoV-2 will not remain asymptomatic throughout the course of the infection.
