Nonfatal scald-related burns among adults aged >/=65 years--United States, 2001-2006.
Scalds, which are burns attributed to hot liquids or steam, account for 33%-58% of all patients hospitalized for burns in the United States. Adults aged >/=65 years have a worse prognosis than younger patients after scald burns because of age-related factors and comorbid medical conditions, and they are subject to more extensive medical treatment than younger adults. To estimate the number of emergency department (ED) visits for nonfatal scald burns among U. ⋯ Two thirds of visits were made by women. Most (76%) of the nonfatal scald injuries occurred at home; 42% were associated with hot food and 30% with hot water or steam. The findings in this report highlight the need for effective scald-prevention programs targeted to older persons.

Case ReportsOseltamivir-resistant 2009 pandemic influenza A (H1N1) virus infection in two summer campers receiving prophylaxis--North Carolina, 2009.
Initial testing of the 2009 pandemic influenza A (H1N1) virus found it susceptible to neuraminidase inhibitors (oseltamivir and zanamivir) and resistant to adamantanes (amantadine and rimantadine). Neuraminidase inhibitors have been used widely for treatment and chemoprophylaxis of 2009 pandemic influenza A (H1N1); however, sporadic cases of oseltamivir-resistant 2009 pandemic influenza A (H1N1) virus infection have been reported worldwide, including nine U. S. cases identified as of September 4. ⋯ A second mutation (I223V) in neuraminidase also was detected in both specimens. This is the first report of oseltamivir resistance in pandemic H1N1 cases with an epidemiologic link. Health-care providers should be aware that antiviral resistance can develop during chemoprophylaxis or treatment with subtherapeutic dosages and should follow published recommendations for antiviral medications.
