MMWR. Morbidity and mortality weekly report

Since the 1988 World Health Assembly resolution to eradicate poliomyelitis globally through 2002, the number of countries where polio is endemic declined from 125 to seven, and the estimated incidence of polio decreased >99%. In 2002, the European Region became the third World Health Organization (WHO) region certified as polio-free, joining the Region of the Americas and the Western Pacific Region, certified polio-free in 1994 and 2000, respectively. Despite these achievements, a provisional total of 1,920 polio cases were reported during 2002, a substantial increase from 483 in 2001, reflecting primarily the large polio epidemic in India. This report summarizes global progress achieved in polio eradication during 2002 and describes remaining challenges.

Case ReportsSevere acute respiratory syndrome (SARS) and coronavirus testing--United States, 2003.
CDC and the World Health Organization (WHO) are continuing to investigate the multicountry outbreak of severe acute respiratory syndrome (SARS). Infection with a novel coronavirus has been implicated as a possible cause of SARS. ⋯ S. residents with SARS and summarizes the clinical histories of the five U.

Nonfatal fall-related traumatic brain injury among older adults--California, 1996-1999.
In the United States, falls are the second leading cause of traumatic brain injury (TBI) hospitalizations overall and the leading cause of TBI hospitalizations among persons aged > or = 65 years. In 1995, TBIs resulted in an estimated $56 billion in direct and indirect costs in the United States. In California, during 1999, a total of 61,475 hospitalizations from falls were reported among persons aged > 65 years. ⋯ As part of CDC's program of state-based TBI surveillance, California hospital discharge data were collected and analyzed to describe fall-related TBIs. This report summarizes the results of that analysis, which support previous findings that persons aged > or = 65 years are at risk for hospitalization for a fall and that same-level falls are far more common among persons aged > or = 65 years than falls from a higher level (e.g., a ladder, chair, or stair). Defining the circumstances of fall injuries and recognizing the type of fall leading to TBI hospitalizations among older persons can help health-care providers conduct risk assessment and management of falls in this population.
