The recent description of chronic hepatitis E in organ transplant recipients deserves increased awareness in the context of hepatitis E virus (HEV) infection in immunocompromised individuals. Reported here is what is apparently the first PCR-documented case of acute hepatitis E in a human immunodeficiency virus (HIV)-1-infected patient. The CD4+ T-lymphocyte count was 246/mm3. The IgM anti-HEV antibody and HEV RNA tests results from serum were positive. Hepatitis was benign, and chronic HEV infection was ruled out. The HEV genotype was 3f. The patient did not report recent travel abroad. HEV should be tested in HIV-infected individuals presenting with acute hepatitis. HEV RNA detection is useful in diagnosing HEV infection and in monitoring recovery.

Community-Associated Methicillin-Resistant Staphylococcus aureus

Historically, infection with strains of methicillin‐resistant Staphylococcus aureus (MRSA), which are usually multidrug‐resistant, has been acquired by persons in hospitals, nursing homes, and other health care institutions. These infections are known as health care–associated MRSA infections. Community‐associated MRSA (CA‐MRSA) infection, which bears significant similarities to and differences from health care–associated MRSA infection, appears to be on the rise and has been described in several well‐defined populations, such as children, incarcerated persons, Alaskan Natives, Native Americans, Pacific Islanders, sports participants, and military personnel. CA‐MRSA infection has caused severe morbidity and death in otherwise healthy persons. Proven, reproducible strategies and programs for preventing the emergence and spread of CA‐MRSA are lacking. Further surveillance and epidemiological and clinical studies on CA‐MRSA infections are necessary for documenting the extent of the problem and for developing and evaluating effective prevention and control efforts.

The anterior nares are the most important screening site of colonization with Staphylococcus aureus. We screened 2966 individuals for S. aureus carriage with swabs of both nares and throat. A total of 37.1% of persons were nasal carriers, and 12.8% were solely throat carriers. Screening of throat swabs significantly increases the sensitivity of detection among carriers by 25.7%.
