Although more than a dozen states have ratified laws that require booster seats for children older than 4 years, most states continue to have child restraint laws that only cover children through age 4 years. Lack of booster seat effectiveness data may be a barrier to passage of stronger child restraint laws. ⋯ Belt-positioning booster seats were associated with added safety benefits compared with seat belts to children through age 7 years, including reduction of injuries classically associated with improper seat belt fit in children.

Severe acute respiratory syndrome (SARS) is an emerging infectious disease that first manifested in humans in China in November 2002 and has subsequently spread worldwide. ⋯ The majority of cases in the SARS outbreak in the greater Toronto area were related to hospital exposure.

Although SARS is associated with significant morbidity and mortality, especially in patients with diabetes or other comorbid conditions, the vast majority (93.5%) of patients in our cohort survived.
