Widespread Household Transmission of SARS-CoV-2 B.1.1.529 (Omicron) Variant from Children, South Korea, 2022.
The role that children play in the transmission of the omicron variant is unclear. Here we report an outbreak that started in young children attending various pediatric facilities, leading to extensive household transmission that affected 75 families with 88 confirmed case-patients in 3 weeks. Tailored social and public health measures directed towards children and pediatric facilities are warranted with the emergence of highly transmissible omicron variant to mitigate the impact of coronavirus diseases 2019 (COVID-19).

Clinical features of Omicron variant infection in 445 patients with coronavirus 19 disease.
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) can mutate frequently and many new strains have emerged thus far. The clinical and epidemiological characteristics differ with each dominant strain. ⋯ None.

Identification of clinical characteristics and risk factors for mortality in COVID-19 is important for early detection and precise case management. The study aimed to describe the sociodemographic, clinical, and laboratory characteristics of in-hospital COVID-19 deaths in Almadinah Almonawarah city, Saudi Arabia, and to identify risk factors for early mortality among them. ⋯ Old age, comorbid illness, and severe respiratory involvement were prevalent among COVID-19 deaths. Comorbidity scores were significantly higher in women. Comorbidity was found to be significantly more associated with early deaths.

Clinical TrialDiaphragm Muscle Weakness Might Explain Exertional Dyspnea Fifteen Months After Hospitalization for COVID-19.
Rationale: Dyspnea is often a persistent symptom after acute coronavirus disease (COVID-19), even if cardiac and pulmonary function are normal. Objectives: This study investigated diaphragm muscle strength in patients after COVID-19 and its relationship to unexplained dyspnea on exertion. Methods: Fifty patients previously hospitalized with COVID-19 (14 female, age 58 ± 12 yr, half of whom were treated with mechanical ventilation, and half of whom were treated outside the ICU) were evaluated using pulmonary function testing, 6-minute-walk test, echocardiography, twitch transdiaphragmatic pressure after cervical magnetic stimulation of the phrenic nerve roots, and diaphragm ultrasound. ⋯ Conclusions: Diaphragm muscle weakness was present 15 months after hospitalization for COVID-19 even in patients who did not require mechanical ventilation, and this weakness was associated with dyspnea on exertion. The current study, therefore, identifies diaphragm muscle weakness as a correlate for persistent dyspnea in patients after COVID-19 in whom lung and cardiac function are normal. Clinical trial registered with www.clinicaltrials.gov (NCT04854863).
