Little is known about the community psychological and behavioral responses to influenza pandemics. ⋯ The lack of substantial change in preventive measures or knowledge about the modes of H1N1 transmission in the general population suggests that community mitigation measures played little role in mitigating the impact of the first wave of 2009 influenza A(H1N1) pandemic in Hong Kong.

Regional differences in the prevalence of Panton-Valentine leukocidin (PVL) and PVL isoform-harboring strains as well as in the local population structure of Staphylococcus aureus may influence the clinical spectrum of S. aureus infections. ⋯ PVL(+) and PVL(-) infections are clearly distinct. MSSA contributes a large but underrecognized burden of PVL(+) disease. Compared with elsewhere in the world, there is a relative abundance of the clade that contains CC93 and CC121 in both northern Australia and Asia.

Rotavirus is a common cause of severe diarrheal disease in children worldwide. Ninety percent of the associated deaths occur in sub-Saharan Africa and South East Asia. Our aim was to review the prevalence of rotavirus infection in Africa over the past 30 years. ⋯ Rotavirus is an important cause of severe diarrheal disease in children <5 years of age in Africa. Clinical trials in South Africa and Malawi have shown that severe rotavirus disease is a vaccine-preventable entity in Africa.
