Diagnostic Accuracy of Web-Based COVID-19 Symptom Checkers: Comparison Study (Preprint)
An evaluation of 10 different web-based COVID-19 symptom checkers found that the number of COVID-19 cases that were assessed correctly varied considerably between different checkers, with Symptoma performing the best. The study assessed 50 COVID-19 case reports along with 410 non-COVID-19 controls and found that only two symptom checkers achieved a good balance between sensitivity…
COVID-19 and Parent Intention to Vaccinate Their Children Against Influenza
Changes in influenza vaccination intentions for 2020 differed significantly between parents whose children received the 2019 influenza vaccine compared to those whose children did not. Among parents whose children did not receive the 2019 vaccine, 34% reported that the COVID-19 pandemic made them less likely to have their child receive the 2020 vaccine. Among those…
COVID-19 Resilience for Survival: Occurrence of Domestic Violence During Lockdown at a Rural American College of Surgeons Verified Level One Trauma Center
There was a statistically significant increase in domestic violence assaults during the COVID-19 lockdown, particularly during the period after school closures, according to a retrospective review of all emergency department patients who presented to an American College of Surgeons verified rural level one trauma center. The increase in cases was observed particularly among white males,…
Increased Dengue Transmissions in Singapore Attributable to SARS-CoV-2 Social Distancing Measures
Social distancing policies in response to the COVID-19 pandemic in Singapore were temporally associated with a 37% increase in the number of dengue cases from baseline in a model controlling for climatic variables associated with mosquito abundance. The authors hypothesize that people may be more likely to be bitten in homes that are often naturally…
Increased Proportion of Physical Child Abuse Injuries at a Level I Pediatric Trauma Center during the Covid-19 Pandemic
The proportion of patients treated for traumatic injuries caused by physical child abuse at the Johns Hopkins Children’s Center during the COVID-19 pandemic was significantly higher compared to the previous two years. During the COVID-19 period, the median age of patients with injuries due to physical child abuse was 11.5 months, and 38% were male….
Clinical Characteristics of Asymptomatic Patients with SARS-CoV-2 in Zhejiang: An Imperceptible Source of Infection
A retrospective study of 22 asymptomatic patients infected with SARS-CoV-2 and 234 symptomatic patients with COVID-19 who were hospitalized in Hangzhou, China found that asymptomatic patients tended to be younger (28 years vs. 48 years), female (77% vs 36%), and had fewer coexisting diseases (5% vs 38%) than symptomatic patients. Dai et al. (Sept 19,…
Sequelae of COVID-19 in Hospitalized Children
A study of 28 hospitalized pediatric patients with COVID-19 in Turin, Italy found that all participants had nasal swabs negative for SARS-CoV-2 by PCR one month after discharge. Lung ultrasound findings had normalized within 5 weeks from hospital discharge in the majority of patients. 20 out of 24 patients developed anti-SARS-CoV-2 IgG at the follow-up…
Symptom Characterization and Outcomes of Sailors in Isolation After a COVID-19 Outbreak on a US Aircraft Carrier
Among sailors who disembarked from the USS Theodore Roosevelt, 736 out of 4,085 (18%) were positive for SARS-CoV-2, of whom 590 (80%) were symptomatic. Six sailors were hospitalized and one died. Loss of taste and smell were reported commonly. The authors note that in confined areas with young essential workers, COVID-19 symptoms may not be…
Case Series of Multisystem Inflammatory Syndrome in Adults Associated with SARS-CoV-2 Infection — United Kingdom and United States, March – August 2020
Morris et al. report 27 cases of multisystem inflammatory syndrome (MIS) associated with SARS-CoV-2 infection in adults that have been reported to CDC or published in the literature. MIS has been previously described among children and adolescents. MIS differs from typical manifestations of severe COVID-19 in that patients with MIS have minimal respiratory symptoms, hypoxemia,…
Waning of SARS-CoV-2 RBD Antibodies in Longitudinal Convalescent Plasma Samples within Four Months after Symptom Onset
A decrease in anti-RBD antibodies was observed over time in a study of individuals who had recovered from SARS-CoV-2 and who gave repeated blood donations. The study determined that the decline was not due to repeated donations, but rather that the anti-RBD response wanes over time of convalescence. The response was found to be relatively…
